FIELD OF THE INVENTION

[0003] The present invention relates compositions useful for modulating Fas and Fas ligand expression on cells and for modulating efficacy of therapeutic agents.

BACKGROUND OF THE INVENTION

[0004] The Fas (Apo-1, CD95) and Fas ligand (FasL, CD95L) system is one of the best-studied cell death systems. Fas is a type-I membrane protein abundantly expressed by cells in various tissues and particularly on activated T cells, heart cells, kidney cells and hepatocytes. FasL is a type-II transmembrane protein expressed particularly on activated T cells and natural killer cells (Nagata, S. Ann. Rev. Genet. 33:29, 1999), and is expressed constitutively in immune-privileged sites as, for example, the eye and testis (Griffith et al. Science 270:630, 1995).

[0005] Fas and FasL interactions (Fas/FasL) play an essential role in the regulation of immune cells and in the elimination of autoreactive cells (Sabelko-Downes et al. Curr. Opin. Immunol. 12:330, 2000). In addition, Fas/FasL mediates the killing of cancer cells and of virus-infected cells (Famularo et al. Med. Hypoth. 53:50, 1999; Owen-Schaub et al. Int. J. Oncol. 17:5, 2000). In contrast, FasL, expressed on cancer cells, may attack cells of the immune system (O° Connell, J. Exp. Med. 184:1075, 1996) or facilitate local tumor invasion by killing surrounding tissue (Yoong et al. Am. J. Pathol. 154:693, 1999). FasL, expressed on activated T cells, may also participate in tissue damage in fulminant hepatitis and in graft-versus-host disease (Kondo et al. Nature Med. 3:409, 1997; Braun et al. J. Exp. Med. 183:657, 1996).

[0006] Binding of FasL to Fas, or cross-linking of Fas with agonistic antibodies, induces apoptosis (Nagata, S. Ann. Rev. Genet. 33:29, 1999) that results in cell death. Apoptosis is an active cellular death process characterized by distinctive morphological changes that include condensation of nuclear chromatin, cell shrinkage, nuclear disintegration, plasma membrane blebbing, and the formation of membrane-bound apoptotic bodies (Wyllie et al. Int. Rev. Cytol. 68:251, 1980). A molecular hallmark of apoptosis is degradation of cellular nuclear DNA into oligonucleosomal-length fragments as the result of activation of endogenous endonucleases (Wyllie A. Nature 284:555, 1980). Caspases (cysteine-aspartyl-specific proteases) have been implicated as key enzymes in the execution of the late stage of apoptosis. The binding of FasL to Fas activates a cascade of caspases via a FADD adaptor (Fas-associated protein with death domain), which leads to the cleavage of various cellular substrates and to DNA fragmentation (Nagata, S. Ann. Rev. Genet. 33:29, 1999).

[0007] Synthetic oligonucleotides are polyanionic sequences that can be internalized by cells (Vlassov et al. Biochim. Biophys. Acta 1197:95, 1994) and bind selectively to nucleic acids (Wagner, R. Nature: 372:333, 1994), to specific cellular proteins (Bates et al. J. Biol. Chem. 274:26369, 1999) and to specific nuclear proteins (Scaggiante et al. Eur. J. Biochem. 252:207, 1998), and inhibit cell proliferation. Proliferation is the culmination of the progression of a cell through the cell cycle, resulting in the division of one cell into two cells. Alterations in cell cycle progression occur in all cancers and may result from over-expression of genes, mutation of regulatory genes, or abrogation of DNA damage checkpoints (Hochhauser D. Anti-Cancer Chemotherapeutic Agents 8:903, 1997).

[0008] Synthetic phosphorothioate oligonucleotides containing unmethylated CpG dinucleotides flanked by two 5′ purine and two 3′ pyrimidine (CpG motifs) are reported to induce the synthesis of cytokines by macrophages and B cells, to increase the activity of NK cells and cytotoxic T lymphocytes, and to enhance T-helper 1 response (Ballas et al. J. Immunol. 157:1840, 1996; Klinman et al. Proc. Natl. Acad. Sci. USA93:2879, 1996; Lipford et al. Eur. J. Immunol. 27:2340, 1997). A 20 base synthetic CpG motif is reported to block Fas expression on activated B cells and to block apoptosis induced by anti-Fas monoclonal antibodies (Wang et al. Cell. Immunol. 180:162, 1997). Irradiation is reported to upregulate the expression of Fas on cancer cells (Sheard et al. Int. J. Cancer 73:757, 1997; Nishioka et al. Int. J. Mol. Med. 3:275, 1999).

[0009] The ability to modulate the Fas/FasL system has many clinical applications for use in diseases including, but not limited to, neoplastic autoimmune, degenerative and cardiovascular diseases. However, most prior Fas/FasL modulating agents have proven to be less than adequate in clinical applications. Moreover, many of these agents are inefficient, toxic or have significant adverse effects.

[0010] Therefore, there is a continuing need for novel compositions and methods that modulate the expression of Fas and FasL on cells. There is also a need for novel compositions and methods that modulate the efficacy of Fas and FasL modulatory agents on disease. There is also a need for novel compositions and methods that modulate the expression of Fas and FasL on cells in order to treat diseases in animals or humans associated with altered expression of Fas or FasL on cells.

[0074] Phosphodiester sequences were prepared by Sigma-Genosys (Woodlands, Tex.) using Abacus Segmented Synthesis Technology. Unless stated otherwise, the sequences were dispersed in autoclaved deionized water or in a pharmaceutically acceptable buffer such as, but not limited to, saline immediately prior to use.

[0077] Peripheral blood mononuclear cells (hereinafter, “PBMCs”) were isolated from human blood by Ficoll-Hypaque (Amersham Pharmacia Biotech, Baie d'Urfée, Québec, Canada) density gradient centrifugation.

[0078] Cancer cells and PBMCs were seeded in 6 well flat-bottom microplates and were maintained at 37° C. in a 5% CO2 atmosphere. Unless stated otherwise, 2×105 cells/ml were incubated for 48 h with 0 μg/ml (control) or 100 μg/ml (5.5 μM) (treated) of the sequences.

[0079] Measurement of Fas and of FasL at the Cell Surface

[0080] Fas and FasL expression were measured by flow cytometry using anti-Fas FITC-conjugated monoclonal antibodies and anti-FasL PE-conjugated monoclonal antibodies in a FACScalibur Flow Cytometer (Becton Dickinson, San Jose, Calif., USA) using the CELLQuest program (Becton Dickinson).

[0081] Results are expressed as percentage (%) increase in the expression of Fas and of FasL measured on treated cells compared to control cells.

[0098] Inhibition of Fas Expression on Jurkat Human Leukemia T Cells by Cycloheximide

[0099] Jurkat human leukemia T cells were pre-incubated with 0.0 μg/ml (−CHX) or with 0.1 μg/ml of cycloheximide (+CHX) for 1 h. Ten μg/ml or 100 μg/ml of 6 base SEQ ID NO:5 (GGGTGG) was added to both the −CHX and +CHX cells and the incubation was continued for 24 hours and for 48 hours (Table 10).

[0100] As shown in Table 10, SEQ ID NO:5 upregulated Fas expression on Jurkat T cells. With 10 μg/ml of SEQ ID NO:5, cycloheximide decreased Fas expression 92% after 24 h and 44% after 48 h. With 100 μg/ml of SEQ ID NO:5 cycloheximide decreased Fas expression 65% after 24 h and 23% after 48 h. These data suggest that 6 base SEQ ID NO:5 stimulates de novo synthesis of Fas.

Cell proliferation was measured using dimethylthiazol-diphenyltetrazolium (MTT) reduction (Mosman et al. J. Immunol. Methods 65:55, 1983). MTT was measured at a wavelength of 570 nm using a multiplate spectrophotometer reader (ELX800, Bio-TEK Instruments Inc., Winooski, Vt.).

[0108] EL-4 murine T lymphoma cells are implanted into C57/BL6 lpr/lpr (Fas negative mice). The mice are divided into 30 groups of 10 mice. On day 0, group 1 mice receive saline, group 2 mice receive 1, 10 or 100 mg/kg of SEQ. ID NO:5, group 3 mice receive 1, 10 or 100 mg/kg of SEQ. ID NO:16, group 4 receive 1, 10 or 100 mg/kg of SEQ. ID NO:17, group 5 mice receive 1, 10 or 100 mg/kg of SEQ. ID NO: 18, group 6 mice receive anti-Fas antibodies, group 7 mice receive 1, 10 or 100 mg/kg of SEQ. ID NO:5 +anti-Fas antibodies, group 8 mice receive 1, 10 or 100 mg/kg of SEQ. ID NO: 16 +anti-Fas antibodies, group 9 receive 1, 10 or 100 mg/kg of SEQ. ID NO:17 +anti-Fas antibodies, group 10 mice receive 1, 10 or 100 mg/kg of SEQ. ID NO:18 +anti-Fas antibodies. In these different groups, anti-Fas antibodies are administered at any dose in the range of about 0.003 to about 0.3 mg/kg. Group 1 mice have the most tumor mass, groups 2, 3, 4, 5 and 6 mice have less tumor mass than group 1 mice, and group 7, 8, 9 and 10 mice have the least tumor mass. The efficacy of the SEQ.

In these different groups, anti-Fas antibodies are administered at any dose in the range of about 0.003 to about 0.3 mg/kg. Group 6, 7, 8, 9 and 10 mice show less progression of EAE than group 1, 2, 3, 4 and 5 mice. Group 7, 8, 9 and 10 mice show the least progression of EAE. The efficacy of the SEQ. ID NO:5, the SEQ.
