Invention field
The present invention relates to utilize VEGF (VEGF) receptor antagonist and chemotherapeutics, radiotherapy, and/or the method for other growth factor receptor antagonist therapeutic alliance tumor.
Background of invention
Blood vessel is meant the vascularization of blood capillary from preexist in embryo and adult biology, and known blood vessel is a tumor growth, survival and the key factor that shifts.Somatomedin and receptor thereof, comprise epidermal growth factor (EGF), transforminggrowthfactor-(TGF-α), transforming growth factor-beta (TGF-β), acidity and basic fibroblast growth factor (aFGF and bFGF), platelet-derived somatomedin (PDGF), and VEGF (VEGF) plays a role in the blood vessel of tumor takes place.See Klagsbrun ﹠amp; D ' Amore, Annual Rev.Physiol., 53:217-239 (1991).These somatomedin can be induced receptor activation with combining of its cell surface receptor, cause and the modification signal transduction pathway, cause cell proliferation and differentiation.VEGF, a kind of endotheliocyte-specificity mitogen, then different with these factors, this is to promote endothelial cell proliferation and work as blood vessel generation derivant by specificity because of it.
VEGF is a kind of isotype biglycan albumen of being made up of the subunit of two 23kD, and it is a kind of stronger vascular permeability derivant, and the stimulant of endothelial cell migration and propagation is important surviving factor for the blood vessel of new formation.VEGF has 4 kinds of different monomer isotypes, and they are to produce from the alternative splicing of mRNA.They comprise two kinds of film combining form (VEGF 206And VEGF 189) and two kinds of soluble form (VEGF 165And VEGF 121).In removing extraplacental all human tissues, VEGF 165The content of isotype is the highest.
VEGF is the important regulator that blood vessel takes place, blood vessel is meant neovascularity because the original position of endothelium precursor is broken up (angioblast) and from the beginning grown, VEGF is at (the Breier etc. of embryonal tissue, Development (Camb.), 114:521 (1992)), macrophage, and the propagation epidermal keratinocytes (Brown etc. in the wound healing process, J.Exp.Med., 176:1375 (1992)) expresses in, and relate to tissue edema (Ferrara etc., Endocr.Rev., 13:18 (1992)) with inflammation-related.In situ hybridization research is verified, VEGF is high level expression in a lot of people's tumors are, comprises glioblastoma multiforme, hemangioblastoma, central nervous system's tumor and AIDS-dependency Kaposi (Plate etc., (1992) Nature 359:845-848; Plate etc. (1993) CancerRes.53:5822-5827; Berkman etc. (1993) J.Clin.Invest.91:153-159; Nakamura etc. (1992) AIDS Weekly, 13 (1)).High-caliber VEGF observes (Shweiki etc., (1992) Nature359:843-845) in also can taking place at the blood vessel of hypoxia inducible.
The biological respinse of VEGF is by its high-affinity receptor mediation, and they are the selective expression on the endotheliocyte in embryo's generation (Millauer, Cell, 72:835-846 (1993)) and the neoplastic process.Vegf receptor (VEGFRs) is III receptoroid type tyrosine kinase normally, it is characterized in that having in the outer receptor ligand binding domain of they aminoterminal born of the same parents some, the ring of 5 or 7 immunoglobulin-likes (Kaipainen etc., J.Exp.Med., 178:2077-2088 (1993)) normally.Two other district comprises that one is striden film district and the interior catalytic domain of carboxyl terminal born of the same parents, it can be by the insertion of kinases (interkinase) sequence in the hydrophilic of different length, be also referred to as kinases and insert territory disconnection (Terman etc., Oncogene, 6:1677-1683 (1991)).VEGFRs comprises by Shibuya etc., Oncogene, the fins sample tyrosine kinase receptor (flt-1) of 5:519-524 (1990) order-checking, or VEGFR-1, the WO92/14248 that submits on February 20th, 1992, with Terman etc., Oncogene describes among the 6:1677-1683 (1991), and by Matthews etc., Proc.Natl.Acad.Sci.USA, 88:9026-9030 (1991) order-checking, contain receptor/fetal livers kinases (KDR/flk-1) that kinases inserts the territory, or VEGFR-2, certain other receptor also can be in conjunction with VEGF as neuropilin-1 and-2.Other tyrosine kinase receptor, VEGFR-3 (flt-4) can be in conjunction with congener VEGF-C and the VEGF-D of VEGF, and even more important in vasculolymphatic growth.
High-caliber Flk-1 expresses (Plate etc., (1992) Nature 359:845-848) by soaking into gliomatous endotheliocyte.The level of Flk-1 can be raised (Plate etc., (1993) CancerRes.53:5822-5827) by the VEGF specificity that people's glioblastoma produces.The high level expression of Flk-1 in the glioblastoma relevant with endotheliocyte (GAEC) shows that it is derivative in neoplastic process that receptor active is likely, this is because almost detect the transcript less than Flk-1 in normal brain endothelial cell.This rise is limited at and the very near vascular endothelial cell of tumor.With in and anti-VEGF monoclonal antibody (mAbs) the blocking VEGF activity xenograft that can the suppress people's tumor (Kim etc. that in nude mice, grow, (1993) Nature 362:841-844), thus show the direct effect of VEGF in the blood vessel relevant with tumor takes place.
Though the VEGF part raises in tumor cell, and its receptor also raises in soaking into the vascular endothelial cell of tumor, and VEGF part and receptor thereof the expression in the normal cell that takes place to have nothing to do with blood vessel is lower.Therefore, this normal cell can not be affected owing to the interaction between blocking VEGF and receptor thereof, takes place and tumor growth thereby suppress blood vessel.
The antagonist that the purpose of this invention is to provide vegf receptor.Another object of the present invention provides uses this vegf receptor antagonist, particularly uses this vegf receptor antagonist and radiotherapy, and chemotherapy or other receptor antagonist are united and suppressed the blood vessel generation, suppress or alleviate the method for mammal tumor growth thus.

Growth factor receptor antagonist
The used growth factor receptor antagonist (except the vegf receptor antagonist) of the present invention comprises all substances that the part that can suppress growth factor receptors stimulates growth factor receptors.The inhibition of this stimulation can suppress to express the cell growth of growth factor receptors.
Some example that relates to tumorigenic growth factor receptors is epidermal growth factor (EGFR), platelet-derived somatomedin (PDGFR), insulin like growth factor (IGFR), nerve growth factor (NGFR), and the receptor of fibroblast growth factor (FGF).
Preferably, the used growth factor receptor antagonist of the present invention is the EGFR antagonist.EGFR antagonist of the present invention is a biomolecule, micromolecule, or any other material, they can suppress the EGFR activation, suppress the tyrosine kinase activity of EGFR thus, and prevent the receptor autophosphorylation, and other protein phosphorylation that relates to various EGFR signal pathways.The activatory inhibition of EGFR is meant the activatory any reduction of EGFR, and it need not to stop fully or stop the activation of EGFR.
In addition, the activatory inhibition of EGFR of the present invention's definition is meant because the EGFR that EGFR antagonist and acceptor interaction produce suppresses.Interaction is meant sufficient physics or chemical interaction between EGFR antagonist and the receptor, so could suppress the activity of tyrosine kinase.Those skilled in the art should understand this chemically interactive example, and it is included between EGFR antagonist and the receptor, and association known in the art or bonding also comprise covalent bonding, ionic bonding, hydrogen bonding etc.Form contrast with the EGF antagonist, it and ligand interaction suppress activation thus.
According to the concrete condition of other somatomedin, the activatory increase of EGFR may be because ligand level raises, EGFR gene amplification, and receptor transcription increases or causes that the sudden change increase of raising receptor signal causes.The amplification of coding EGFR gene causes increasing with the bonded part number of EGFR, thereby further stimulates cellular proliferation.EGFR also can not have overexpression under the situation of gene amplification, is to transcribe by increasing EGFR by inference, mRNA translation, or the sudden change of protein stability is finished.The EGFR mutant is in glioma, and nonsmall-cell lung cancer identifies in ovarian cancer and the carcinoma of prostate that they have the tyrosine kinase of constitutive activity, shows the active effect of high-level EGFR, rather than the effect of EGFR overexpression in these cancers.See, for example, Pedersen etc., Ann.Oncol., 12 (6): 745-60 (2001).(EGFRvIII of III type EGFR sudden change-various name, de2-7EGFR or AEGFR-lack the part by the outer ligand binding domain of born of the same parents of exon 2-7 coding); See Wikstrand etc., Cancer Res., 55:3140-3148 (1995).
In one of them embodiment of the present invention, the EGFR antagonist suppresses EGFR and combines with its part.But the extracellular domain of part and EGFR outside combine the costimulatory receptor dimerization, EGFR autophosphorylation, the activation of the inside cytoplasmic tyrosine kinase domain of receptor and relate to the initiation of the synthetic and a plurality of signal transduction pathways that cell division is regulated of DNA.The part of EGFR comprises, for example, and EGF, TGF-α, amphiregulin, heparin-in conjunction with EGF (HB-EGF) and betarecullulin.EGF and TGF-α are the main endogenic ligands that can cause the stimulation of EGFR-mediation, although TGF-α promote aspect the blood vessel generation more effective.
In another embodiment of the present invention, the EGFR antagonist is in conjunction with EGFR.Should understand the EGFR antagonist can divide outside the combination with the born of the same parents outside of EGFR, suppresses or does not suppress the combination of part, or combine with tyrosine kinase domain is inner.Example in conjunction with the EGFR antagonist of EGFR comprises, but is not restricted to, and biomolecule as the antibody special to EGFR (and function equivalent), directly acts on the synthetic inhibitors of kinases of EGFR cytoplasm domain, as micromolecule.
The biomolecule that EGFR antagonist of the present invention is preferably special to EGFR, more preferably antibody, or its function equivalent.Description to the used antibody of the present invention can be found in the part of " antibody " by name.In addition, after antibodies, preferably make EGFR-antibody complex internalization and degraded, prevent that receptor from being utilized by cell again.
Known biomolecule EGFR antagonist is ERBITUX TM(IMC-C225), it is chimeric (people/mice) monoclonal antibody special to EGFR.See, for example, U.S. Patent number 4,943,533 (Mendelsohn etc.); U.S. Patent number 6,217,866 (Schlessinger etc.); U.

The vegf receptor antagonist
In embodiment, vegf receptor antagonist specificity is in conjunction with the epitope on the vegf receptor extracellular domain therein.The extracellular domain of vegf receptor is a part-in conjunction with the territory.Part-can find at any one end of receptor in conjunction with the territory, but be usually located at amino terminal.
Some examples of vegf receptor comprise protein tyrosine kinase receptor, as the flt-1 (VEGFR-1) that mentions in the document, KDR and flk-1 (VEGFR-2).Illustrate that clearly this description will be followed the conventional document nomenclature of vegf receptor except as otherwise noted or otherwise.KDR (VEGFR-2) is known as the human form (Terman etc., above-mentioned) of the vegf receptor with MW 180kD.Flk-1 (VEGFR-2) is known as the Mus homologue (Matthews etc., above-mentioned) of KDR.Flt-1 (VEGFR-1) is known as the multi-form of vegf receptor, but receptor related with KDR/flk-1 (VEGFR-2).See Shibuya etc., above-mentioned.
Other vegf receptor comprises with those of VEGF crosslinked labeling, or with KDR (VEGFR-2) altogether-those of immunoprecipitation.The molecular weight of these some form known of vegf receptor is approximately 170KD, and 150KD, 130-135KD, 120-125KD and 85KD. see, for example, and Quinn etc., Proc.Nat ' l Acad.Sci USA, 90:7533-7537 (1993); Scher etc., J.Biol.Chem., 271:5761-5767 (1996).
Common and the cell of vegf receptor is as the endotheliocyte combination.Vegf receptor also can with non--endotheliocyte, as the tumor cell combination.Optionally, vegf receptor can be free on cell, preferred soluble form.
But antagonist neutralize VEGF receptor of the present invention.In this manual, in and receptor be the inherent kinase activity deactivation of instigating receptor, thereby transduction signal.The neutral reliable determination method of vegf receptor is to suppress receptor phosphorylation.
The present invention is not subjected to the restriction of the neutral any special mechanism of vegf receptor.When this application of application, also do not understand mechanism, by wherein the neutral mechanism of a kind of antagonist need not be with identical by the neutral mechanism of another kind of antagonist by antibody neutralize VEGF receptor.Some possible mechanism comprises that hindering the VEGF part combines the territory combination with the born of the same parents of vegf receptor are outer, and prevents receptor dimerization or oligomerization.Yet, can not get rid of other mechanism.
Vegf receptor of the present invention (or VEGFR) antagonist is a biomolecule, micromolecule, or any other material of inhibition receptor VEGFR subfamily.The activatory inhibition of receptor VEGFR subfamily is meant the activatory any reduction of VEGFR.That is, when hindering activation, need not to stop fully the VEGFR activation.In addition, after the activatory inhibition of the defined VEGFR of the present invention is meant that VEGFR antagonist and VEGFR interact, the inhibition of VEGFR antagonist.Association is meant sufficient physics or chemical interaction between VEGFR antagonist and the VEGFR, thereby suppresses the tyrosine kinase activity of receptor.Those skilled in the art should understand this chemically interactive example, comprise association known in the art or bonding, comprise covalent bonding, ionic bonding, hydrogen bonding etc.Therefore, VEGFR antagonist of the present invention can suppress the tyrosine kinase activity of receptor, hinders receptor autophosphorylation and various other protein phosphorylations that relate to the VEGFR signal pathway.This approach that relates to blood vessel generation and angiopoietic adjusting comprises following any: phospholipase C γ (PLC γ) approach or phosphatidylinositols 3 ' kinases (PI3-K)/Akt and the activated protein kinase of mitogen (MAPK) approach.See, for example, Larriv é e etc., Int ' l J.Mol.Med., 5:447-56 (2000).
Receptor VEGFR subfamily is characterised in that 7 immunoglobulin-like rings in the extracellular domain, single exist (III receptoroid tyrosine kinase) of striding the tyrosine kinase domain that ruptures in film district and the intracellular region.Receptor VEGFR subfamily also has a lot of known members, and its example comprises VEGFR-1, VEGFR-2, and VEGFR-3.It is believed that KDR (VEGFR-2) is main VEGF signal transducer, it can cause the propagation of endotheliocyte, migration, and differentiation, pipe forms, the keeping of the increase of vascular permeability and vascular integrity.VEGFR-1 has more weak kinase activity, and when being subjected to the VEGF stimulation, can not produce mitogenic response, combines with VEGF though it can be higher than the about 10 times affinity of KDR (VEGFR-2).VEGFR-1 also relates to the generation of VEGF and the inductive mononuclear cell of placental growth factor (PIGF) and macrophage migration and tissue factor.
For above-mentioned EGFR, the activatory increase of VEGFR may be by high-caliber part, the amplification of VEGFR gene, the increase of receptor transcription or cause that the sudden change of raising receptor signal causes.
In one of them embodiment of the present invention, the VEGFR antagonist suppresses VEGFR and combines with its part.But part combines the costimulatory receptor dimerization with the extracellular domain of VEGFR outside, VEGFR autophosphorylation, the activation of the inner cytoplasmic tyrosine kinase domain of receptor and relate to vascularization and the initiation of a plurality of signal transduction pathways of the adjusting that blood vessel takes place.
The part of VEGFR comprises VEGF and congener P1GF thereof, VEGF-B, VEGF-C, VEGF-D, and VEGF-E.For example, P1GF, it is a dimerization secreting type factor in conjunction with VEGFR-1, and it is by the villus cell trophoderm, and the outer trophoderm of syntrophoblast and fine hair produces in a large number, and the homology of its aminoacid sequence and VEGF is very high.The mankind have 3 kinds of isotypes, P1GF-1, P1GF-2, and P1GF-3.To lacking studies confirm that of P1GF mice, this somatomedin itself takes place to have nothing to do with blood vessel, but but the blood vessel in the specificity adjusting pathological process takes place and the osmosis of VEGF.And VEGF-D and VEGF-C are closely related, and this is to can not find N-and the terminal existence of extending of C-because be in other VEGF family member.In adult tissue, the mRNA of VEGF-D is at heart, lung, and skeletal muscle, the content in colon and the small intestinal is the abundantest.The analysis that the VEGF-D receptor-specific is carried out discloses, and VEGF-D is the part of VEGFR-2 (Flk1) and VEGFR-3 (Flt4), and can activate these receptors; Yet VEGF-D is not in conjunction with VEGFR-1.In addition, VEGF-D is the mitogen of endotheliocyte.
In another embodiment of the present invention, the VEGFR antagonist is in conjunction with VEGFR.Will be appreciated that the VEGFR antagonist can divide outside the combination with the born of the same parents outside of VEGFR, suppresses or do not suppress the combination of part, the VEGFR antagonist also can combine with tyrosine kinase domain is inner.Example in conjunction with the VEGFR antagonist of VEGFR comprises, but is not restricted to, and biomolecule is as receptor ribozyme and the antibody (or its function equivalent) special to VEGFR with directly act on the synthetic inhibitors of kinases in VEGFR cytoplasmic structure territory, as micromolecule.Preferred VEGFR antagonist of the present invention is the biomolecule special to VEGFR, and more preferably antibody or its function equivalent below will be for a more detailed description to them.Optionally, VEGFR antagonist of the present invention is the micromolecule inhibitors of kinases, will be described in detail it below.

The activity of EXAMPLE V antibody
EXAMPLE V-1 ELISA and use the DC-101 immunoprecipitation
It is found that rat IgG1 monoclonal antibody DC-101 is special to Mus tyrosine kinase receptor flk-1 (VEGFR-2).The ELISA data show, the flk-1 (VEGFR-2) of antibody and purification: SEAP combines, but do not combine with alkali phosphatase or other receptor tyrosine kinase such as FLK-2.As shown in Figure 1, DC-101 can make Mus flk-1 (VEGFR-2): the SEAPS immunoprecipitation, and can not make independent SEAPS immunoprecipitation.
EXAMPLE V-2 usefulness DC-101 suppresses Flk-1 (VEGFR-2) receptor phosphorylation
Experimentize so that determine whether DC-101 can pass through its related part VEGF 165In and the phosphorylation of flk-1 (VEGFR-2) in the C441 cell.In these researchs, monoclonal antibody and VEGF joined in the cell monolayer 15 minutes simultaneously in room temperature.These conditions are designed to measure antibody to the bonded competitive effect of receptor/ligand (competitive inhibition).These measurement results shown in Fig. 2 a show, when measuring cell under the situation that is having DC-101 to exist, and VEGF 165Inductive flk-1 (VEGFR-2)/fms receptor phosphorylation significantly reduces.In addition, these data show, Mab and VEGF 165The receptor that competition stops part to cause activates fully.In order to measure the sensitivity that suppresses due to VEGF-flk-1 (VEGFR-2) the interaction partners DC-101, the C441 cell is the VEGF with maximal stimulus concentration 165(40ng/ml) in conjunction with the TPPA of various levels.The titrating result of these Mab provides in Fig. 2 b.When the concentration of DC-101 during greater than 0.5 μ g/ml, VEGF 165Due to flk-1 (VEGFR-2) phosphorylation significantly reduce.These data show, the antibody of relatively low concentration (<1 μ g/ml) is enough to suppress the receptor activation due to the part.In that the part of 80ng/ml is excessive when existing, 5 μ g/ml antibody just can neutralize VEGF 165Stimulation to flk-1 (VEGFR-2).In contrast, use CSF-1 to go up the effect of test DC-101 at the fms/FLK-2 receptor (10A2 cell line) that stimulates fully.Under these conditions, DC-101 is to not influence of receptor activation.
EXAMPLE V-3 utilizes DC-101 to suppress research
By studying degree and the specificity that further assessment Mab suppresses, wherein before adding part, with cell precincubation DC-101, so that antibody and receptor are fully acted on.In these experiments, with 5 μ g/ml DC-101, (ImClone, NY) Zhi Bei rat anti-FLK-2Mab (2A13) and control rats IgG1 (Zymed Labs) room temperature incubation cell monolayer is 15 minutes, adds 40ng/ml VEGF then by conventional method 165Incubation is 15 minutes again.In order relatively to measure, wherein add DC-101 and VEGF simultaneously 165(competitive inhibition).The result of these researchs (Fig. 4) shows, can eliminate VEGF fully with anti--flk-1 (VEGFR-2) monoclonal antibody of flk-1 (VEGFR-2)/fms cells transfected precincubation 165Due to receptor activation.Similar results is to use VEGF 121Stimulate observed.When flk-1 (VEGFR-2) phosphorylation due to the rat antibody that adds irrelevant isotype coupling can not influence VEGF, the activity of the identical trace of surveying with anti--fms polyclonal antibody shows that the level of per pass receptor protein is identical.These data show that the observed phosphorylation inhibition of use DC-101 is the blocking-up owing to receptor activation, rather than lacks receptor protein in the test specimen.
EXAMPLE V-4 combines by facs analysis DC-101 and C441 cell
Measure the combining of 3T3 cell of mAb and flk-1 (VEGFR-2)/fms receptor (C441 cell) transfection by facs analysis.Result shown in Figure 6 proves, chimeric flk-1 (the VEGFR-2)/fms that expresses on the C441 cell surface can be by mAb DC-101 specific recognition, and can not be by at relevant tyrosine kinase receptor, the identification of the isotype antibody of FLK-2 incubation.The mAb-receptor is determined according to algoscopy in the interactional efficient of cell surface, wherein measures the bonded varying level of mAb on complete C441 cell.These results shown in Figure 7 show, mAb with about 500ng/ml relatively than significant affinity and flk-1 (VEGFR-2)/fms receptors bind.These results show that the flk-1 (VEGFR-2) of mAb pair cell surface expression has stronger affinity.
EXAMPLE V-5 is by the reactivity of immune precipitation determination DC-101
The extent of reaction of DC-101 and flk-1 (VEGFR-2)/fms receptor is by after the VEGF activation, measures antibody and makes the ability of receptor immunoprecipitation and further assessment.Fig. 8 represents the immunoprecipitation due to the mAb DC-101 of C441 cells phosphorylation flk-1 (VEGFR-2)/fms receptor that VEGF stimulates.The result shows that the DC-101 monoclonal antibody has similar receptor acting level with anti-fms polyclonal antibody, and rat anti FLK-2 antibody 2H37 (IgG1) and 2A13 (IgG2a) then do not have reactivity.Experimentize then, determine whether mAb DC-101 can be in the inductive flk-1 of maximal stimulus concentration (40ng/ml) neutralize VEGF (the VEGFR-2)/fms phosphorylation of part.In these researchs, monoclonal antibody and part are joined in the cell monolayer simultaneously, or before ligand stimulation, add, room temperature measuring 15 minutes.These conditions are studied, bonded competitive effect of receptor/ligand (competitive inhibition) and pre-binding antibody are stoped the receptor activation effect to determine antibody.These measurement results shown in Figure 4 show that the phosphorylation of flk-1 (VEGFR-2)/fms reduces by adding mAb and VEGF simultaneously, and can obviously be suppressed with the pre-bonded antibody of receptor.The densitometric scan of these data discloses, and mAbDC-101 and flk-1 (VEGFR-2)/fms interacts, suppress phosphorylation to the receptor matched group (4 road) that stimulates fully 6% (5 roads, P) with 40% (6 roads, C).According to our deducibility mAb DC-101 and the ligand-receptor interaction keen competition of these data, in and the activation of flk-1 receptor.For the sensitivity of determining to suppress due to VEGF-flk-1 (VEGFR-2) the interaction partners mAb DC-101, when antibody concentration increases gradually, with maximum VEGF level determination C441 cell.Mensuration is in competition with in advance in conjunction with under the condition, carries out with mAb.The titrating result of these mAb provides in Fig. 9.When mAb DC-101 and concentration during, can be observed the remarkable reduction of flk-1 (VEGFR-2) phosphorylation greater than the VEGF antibody competition of 0.5 μ g/ml.These data also show, the pre-binding antibody of relatively low concentration (<1 μ g/ml) is enough to suppress fully the receptor activation due to the part.
EXAMPLE V-6 is measured the activity of DC-101 by the phosphorylation assay method
For further assessment mAb DC-101 carries out phosphorylation assay to the antagonism of receptor activation, wherein the antibody of fixed amount (5 μ g/ml) is joined that (Fig. 3 a) in the C441 cell that part stimulated that consumption increases gradually.Reading by light densitometry quantizes to have and the inductive phosphorylation level of each ligand concentration when not having mAb DC-101.The figure of these data that Fig. 3 b provides shows, even there is excessive VEGF to exist, antibody also can part in and receptor phosphorylation.In order to assess the specificity of mAb DC-101, tested among the antibody competition inhibition 3T3 transfectional cell series 10A2 ability of the inductive fms/FLK-2 receptor activation of CSF-1 to receptor activation.In these experiments, the mAb DC-101 and the known complete activatory CSF-1 concentration of receptor (20-40ng/ml) that causes of having tested 5 μ g/ml.These results shown in Figure 10 show that mAb DC-101 is to the not effect of fms/FLK-2 receptor phosphorylation of CSF-1 mediation.
EXAMPLE V-7 is by the inhibitory action of precincubation research DC-101
By studying degree and the specificity that further assessment antibody suppresses, wherein DC-101 or irrelevant antibody are used cell precincubation before adding part, fully act on to guarantee antibody and receptor.In these experiments, cell monolayer is before adding 40ng/ml VEGF, with 5 μ g/mlDC-101, rat anti FLK-2mAb (2A13) or control rats IgG1 (Zymed Labs) precincubation.In order to compare, also carried out competitive assay, wherein add antibody and VEGF simultaneously.The result of these researchs shows, have only and can eliminate the receptor activation due to the VEGF to anti-flk-1 (VEGFR-2) monoclonal antibody and flk-1 (VEGFR-2)/fms cells transfected precincubation fully, the rat antibody of the irrelevant isotype coupling of adding then can not influence flk-1 (VEGFR-2) phosphorylation due to the VEGF.The activity (Figure 11) of surveying same trace with anti--fms polyclone shows that the receptor protein of per pass is on level terms.These data show, the cell observation of handling with mAb DC-101 to the phosphorylation deficiency be owing to blocked the phosphorylation of the inductive equivalent expressed receptor of VEGF-.
The interaction of EXAMPLE V-8 antibody and homoreceptor form
Experimentize then, determine anti-flk-1 (VEGFR-2) monoclonal antibody whether with human endothelial cell on the homoreceptor form interact.On clone's HUVEC cell (ATCC), the titration that the DC-101 that concentration is increased gradually carries out shows, antibody has complicated in conjunction with behavior.Data representation different antibodies and the interaction (Vaisman etc., J.Biol.Chem.265,19461-19466,1990) that is present in the vegf receptor on the endotheliocyte.Then to those similar conditions of Fig. 8 report under, utilize the phosphorylation assay method to describe the specificity of DC-101 and the HUVEC cell interaction of VEGF stimulation.In these researchs, when deduction during ligand component, DC-101 can make the protein band immunoprecipitation of HUVEC cell, those similar (Figure 12) of described protein band molecular weight and crosslinked VEGF-receptor band.When the VEGF irritation cell (relatively 1 road and 2 roads among Figure 12), these bands show the increase of phosphorylation.In addition, the inductive receptor band of VEGF phosphorylation is to strengthen (3 roads among Figure 12) by add 1 μ g/ml heparin when measuring.These find and had before reported, when having the low concentration heparin, VEGF consistent with the bonded increase of endotheliocyte (Gitay-Goren etc., J.Biol.Chem.267,6093-6098.1992).
Be difficult to determine that immunoprecipitation albumen and DC-101 interaction can produce the phosphorylation band of the observed complexity of Figure 12, Figure 12 has provided various receptor forms and has gone up combining of VEGF with HUVEC, and stimulates their associating probabilities of back.It is reported that molecular weight is about 180 (KDR (VEGFR-2)), 155,130-135, the receptor form of 120-125 and 85 cell surface expression can be in conjunction with the VEGF on the HUVEC.The probability of some not isoacceptor forms different dimerization behind ligand stimulation has been emphasized in this discovery, and the mode of its different dimerization is similar to KDR-flk-1 (VEGFR-2/VEGFR-1).Yet except KDR (VEGFR-2), the accurate characteristic of these receptor forms and effect are also indeterminate.So, antibody response may because with the vegf receptor that does not wherein rely on KDR (VEGFR-2) in one of interact and to cause.
By facs analysis as can be known, DC-101 neither with the people KDR (VEGFR-2) of ELISA form reaction, do not combine with the HUVEC of fresh separated yet.These results show that DC-101 and people KDR (VEGFR-2) directly effect are unlikely.
By facs analysis as can be known, different with DC-101, Mab 25 and Mab 73 all with the people KDR (VEGFR-2) of ELISA form reaction, and in conjunction with the HUVEC of fresh separated.
The mitogenesis algoscopy of EXAMPLE V-9 HUVEC
Have and when not having antibody to exist, antagonist is tested in the mitogenesis algoscopy of the HUVEC cell (ATCC) that stimulates with VEGF, can be observed the inhibitory action of DC-101 to endotheliocyte.These results show, the remarkable increase of the cell proliferation due to the VEGF can approximately be reduced 35% by DC-101.Under the growth conditions that these algoscopys are used, the heparin cell growth does not have different effects.
Because DC-101 can work to the receptor phosphorylation of inductive propagation of VEGF and HUVEC, therefore can expect that these results are because Mab and indefinite receptor form interact, wherein indefinite receptor form is difficult near cell surface, but can be to some effect of HUVEC growth performance, although this effect is very little.And DC-101 can show the suitable phosphorylation band of the molecular weight fact that immunoprecipitation comes out from the HUVEC that VEGF-stimulates, DC-101 can with indefinite flk-1 (VEGFR-2) the sample protein-interacting relevant with activated receptor.
EXAMPLE V-10 Mab 25 and Mab 73 combine with C441 cell and HUVEC's
By facs analysis as can be known, Mabs 25 and 73 can be in conjunction with C441 and HUVEC, and can be in two cell lines internalization.The result of Western blotting shows that two kinds of anti-flk-1Mabs can detect the FLK/fms receptor band that immunoprecipitation comes out from the C441 cell by anti-fms polyclonal antibody.(seeing the method for top EXAMPLE IV-2).These antibody can cause the specificity neutralization of the inductive flk-1 of VEGF (VEGFR-2)/fms receptor, and mice pdgf receptor phosphorylation or the people EGF receptor phosphorylation due to the EGF due to the PDGF do not acted on.(seeing the method for the foregoing description IV-1).By proliferation assay as can be known, they have the ability of the HUVEC to 50% that suppresses the VEGF stimulation, and DC-101 then influences the very little degree that grows to.
The immunoprecipitation of EXAMPLE V-11 KDR (VEGFR-2) and Mab25 and Mab73
On behalf of a class, KDR (VEGFR-2) can utilize Mab 25 and Mab 73 phosphoprotein that immunoprecipitation comes out from activation HUVEC.KDR (VEGFR-2) detects in Western blotting, and uses anti-flk-1/KDR (VEGFR-1/VEGFR-2) polyclonal antibody (IM142) to carry out immunoprecipitation analysis from the HUVEC that goes down to posterity in early days that VEGF-stimulates.On the contrary, utilize these antibody immunoprecipitation comes out from the HUVEC that VEGF-stimulates band and IM142 cross reaction, and not with resist-flt-1 (anti-VEGFR-1) polyclonal antibody cross reaction.Based on experimental evidence, infer that according to these discoveries Mabs can influence the activity of KDR among the HUVEC (VEGFR-2), and hint is relevant with the breeder reaction in the activation endotheliocyte as the KDR (VEGFR-2) of vegf receptor.(seeing the method for top EXAMPLE IV-3)
The existence of vegf receptor form on the non-endothelium of example VI (tumor) cell
By immunoprecipitation some tumors system is screened, determining they and the albumino reaction of DC-101, and with anti-phosphotyrosine detection.The immunoblotting of cell line 8161 (melanoma) and A431 (epidermoid carcinoma) can produce molecular weight and be about 170 and the phosphorylation band of 120kd.These results show that people's vegf receptor form is at non-endotheliocyte, as expressing in the tumor cell.
Similarly experiment shows that KDR (VEGFR-2) sample receptor is expressed among the OVCAR-3 at ovarian cancer cell line.As if these cells also secretion of VEGF.The phosphorylation band is to utilize anti--KDR (VEGFR-2) polyclonal antibody immunoprecipitation from the OVCAR-3 cell that VEGF-stimulates to come out, and by western blot analysis as can be known, it can react with anti-flk-1 (VEGFR-2) Mabs.And, utilize the Mus Mabs band that immunoprecipitation comes out from these cells can with same polyclonal antibody cross reaction.In addition, by proliferation assay as can be known, some mouse-anti-flk-1 (VEGFR-2) Mabs can cause these cell inhibiting effects.These results have confirmed the non-endothelium expression (that is, expressing) of people's vegf receptor form on tumor cell.The data of phosphorylation and proliferation assay also show, in the VEGF scalable tumor generating process, and the receptor active of autocrine and paracrine mode.(seeing the method for the foregoing description IV-3)

Can design is carried out studying in the body be the growth of tumour cell that block VEGF expression for definite anti-flk-1 (VEGFR-2) monoclonal antibody.In these experiments, used people's glioblastoma multiforme cell line, it has high-caliber VEGF information, and can not handle after 24 hours in having the culture medium of serum, secretes the VEGF somatomedin (Fig. 5) of about 5ng/ml.
The 0th day, give nude mouse (nu/nu; Charles River Labs) 1,000,000 spongioblast oncocytes of flank injection 1-2.Beginning on the same day, giving animal peritoneal injection DC-101 or control antibodies (100 μ g/ animal).Subsequently, the 3rd, 5,7,10,12,14,17,19 and 21 days, mice was accepted Antybody therapy.The 0th, 3,5,7,10,12,14,17,19 and 21 days, inject the control rats antibody of 100 μ g DC-101 or Mus FLK-2 (2A13) receptor to animal, every animal inoculates 1mg altogether.Tumor began at the 5th day to occur, and continued 50 days always.Measure tumor size with caliber gauge every day, and utilize following formula to calculate gross tumor volume: p/6x than major diameter x (than minor diameter) 2(Baselga J.Nat ' l CancerInst.85:1327-1333).At least measure weekly 3 times, and according to top described calculating gross tumor volume.In the DC-101 group, an early stage death of suffering from the animal of tumor in research is arranged, can not be used to measure the statistically-significant difference between two groups.
After Figure 14 a and 14b represent 38 days, between DC-101 and the 2A13 matched group, the comparison that each animal tumor growth alleviates.Though in research process, variation has all taken place for the size of all animal tumors and quantity, the mice for the treatment of with DC-101 shows comprehensive delay in the tumour progression process.Wherein mice of DC-101 group keeps not having tumor until the 49th talent finds less growth.Even then, tumor growth is still significantly suppressed.Data are carried out statistical analysis, so that assess the difference of tumor size between two groups.Data are carried out the standard analysis of covariance, and wherein the tumor size reduced with treatment time.The result shows, the tumor size reduce in time aspect, DC-101 group and the mice obviously different (p<0.0001) of injecting 2A13.
Figure 15 represents the therapeutic effect of DC-101 to nude mouse, has transplanted people's glioblastoma cell line GBM-18 of secretion of VEGF in the described nude mouse.Give mouse bare subcutaneous injection GBM-18 cell, and they are divided into 3 treatment groups: PBS matched group, irrelevant rat IgG1 matched group, and DC-101.Treatment is carried out simultaneously with the xenotransplantation of tumor, and continues for 4 weeks.The result shows, compares with matched group, and the GBM-18 tumor growth in the nude mice for the treatment of with DC-101 significantly reduces.This experiment shows, DC-101 suppresses tumor growth by the VEGF activation of flk-1 (VEGFR-2) on the blocking-up cancer-related vascular endothelial cell, and DC-101 is as having therapeutic value at the resisting of the vascularized tumors of secretion of VEGF-blood vessel propellant.
The tumor intrusion can take place to suppress by eliminating blood vessel in the monoclonal antibody of flk-1 (VEGFR-2) receptor tyrosine kinase.Invasive growth and blood vessel are the key characters of malignant tumor.Two phenomenons all are proved and are suitable for distinguishing benign and virulent keratinocyte in the surface transplantation algoscopy.After being transplanted on the nude mice dorsal muscles with the bonded cell monolayer of collagen gel, initial all tumor cells that form constitute squamous epithelial cancer, but have only pernicious keratinocyte in 2-3 invasive growth in week.But optimum and all induction of vascular generations of malignant cell.Yet the blood vessel of malignant cell reacts and takes place early, and is stronger, and blood capillary is towards pernicious epithelial growth.In addition, in the graft of benign tumor cells, blood capillary disappears after week at 2-3, and pernicious keratinocyte is then kept continual blood vessel occurred level.VEGF (VEGF) and related part thereof play a part crucial in tumor vessel takes place.The administration of DC-101 can destroy continual blood vessel and take place, and invades thereby suppress tumor.Antibody can stop vasoganglion ripe of new formation and further expand, but can not significantly disturb initial blood vessel to induce.These results confirm that the tumor intrusion needs blood vessel formerly to take place, and vegf receptor is most important in the blood vessel of keeping this model system takes place.
The DC-101 of example VII A-2 variable concentrations is to the effect of the glioblastoma (gbm-18) of being established
Give athymic mouse (nu/nu) subcutaneous vaccination GBM-18 (people's glioblastoma multiforme).When the average external volume of tumor reaches 100-200mm 3The time, the beginning Antybody therapy.Treatment comprises following 6 injections (2 times weekly, injected for 3 weeks): (i) DC-101 of per injection 200,400 or 800 μ g; The rat IgG (per injection 400 μ g) of (ii) irrelevant isotype coupling; Or (iii) PBS.Measure gross tumor volume with caliber gauge.Compare with irrelevant monoclonal antibody group with PBS, the tumor suppression of DC-101 group is (*) relatively significantly.
Other experiment susceptible of proof rat anti flk-1 (VEGFR-2) monoclonal antibody DC-101 is to the effect of nude mice GBM-18 tumor growth.The 0th day, give animal (nu/nu; Charles RiverLabs; 10 animal/groups) subcutaneous injection GBM-18 cell (people's glioblastoma [100]; 100 a ten thousand/animal).Began treatment on the 7th day with PBS or DC-101 (per injection 200 μ g), weekly twice, continue 3 weeks (6x).The mean tumour volume and the data that disappear that each group of graphical representation changes in time, (slope is represented with λ to give their tumor growth rates separately among the figure; Solid line) and 99% confidence limit (dotted line).The slope of curve of the animal of handling with DC-101 and obviously different (p<0.01) of PBS.It should be noted that irrelevant rat IgG1 monoclonal antibody (anti-mice IgA; Pharmigen) growth to the GBM-18 xenograft does not influence, its result and use PBS observed similar (not providing data).
The cure rate of people's tumor xenogeneic graft in the nude mice of the alternative increase of the anti-flk-1 of example VII A I (VEGFR-2) antibody radiotherapy-induced
This embodiment is in order to assess the important vegf receptor-2 on the Mus tumor vascular endothelial cell capable of blocking, can the monoclonal antibody DC-101 of flk-1 (VEGFR-2) increase the curability of the tumor xenogeneic graft that fractionated radiotherapy (RT) causes, and can this antibody regulate the radiotherapy side effect of normal structure (mouse skin) simultaneously.
Cai Liao ﹠amp; Method: in the subcutaneous back leg that is implanted to nude mice of human small cell lung carcinoma 54A and glioblastoma multiforme U87.(the 0th day) begin treatment when diameter of tumor reaches 8mm.The DC-101 of per 3 days peritoneal injections 20 or 40mg/kg body weight injects 6 times altogether.Continuous 5 days, the fractionated radiotherapy accumulated dose that equates every day.The 0th day, mice is injection of antibodies for the first time, or beginning RT.For conjoint therapy, the DC-101 administration was beginning in the 0th day, and RT was beginning in the 1st day.After the treatment, measure the tumor size weekly 2-3 time.After in arbitrary group, observing tumor recurrence, follow the tracks of the mice 90 days that local control tumor is arranged.In preceding 30 days behind beginning RT, use the acute skin reaction in score scale assessment tumor radiotherapy zone.
The result: separately the mode that the antibody that uses can dose dependent suppresses two kinds of growth of tumor (but can not disappear).This acting among the 54A than more remarkable in the U87 xenograft.In arbitrary model, compare with carrying out RT separately, can further postpone growth of tumor to the radiotherapy and the DC-101 associating of lowest dose level (25-30Gy altogether).Antibody also is the curative effect that increases RT in the mode of dose dependent.For example, the DC-101 of higher dosage can make the required radiotherapy dosage of local control 50% tumor reduce: be 1.7 times (67.6Gy when carrying out RT separately reduces to the 39.1Gy of conjoint therapy) in the 54A xenograft; In U87 1.3 times (from 97.8-74.8Gy).Also have some particular importances, that this effect that is exactly DC-101 is optionally to tumor.That is, do not detect the parallel change of antibody to the skin radiotherapy side effect.As assessment in other experiment, the raising of the inductive tumor radiotherapy of DC-101 reaction has nothing to do with the change of their radiosensitization or oxidation, and significantly to reduce mesenchyma stroma of tumors hydraulic pressure relevant with antibody.
Conclusion: the result shows jointly, at the antibody of these growth factor molecule major receptors the alternative tumor of strengthening gradation RT of the blocking-up of VEGF-signal pipeline is cured reaction; Therefore and provide a kind of therapy.
