Abstract: The present invention relates to methods and compositions for the specific inhibition of kinase suppressor of Ras (KSR). In particular, the invention provides genetic approaches and nucleic acids for the specific inhibition of KSR, particularly of KSR expression. The invention relates to antisense oligonucleotides and the expression of nucleic acid which is substantially complementary to KSR RNA. Oligonucleotide and nucleic acid compositions are provided. The invention provides methods to inhibit KSR, including inhibition of KSR expression. Methods for blocking gfRas mediated tumorigenesis, metastasis, and for cancer therapy are provided. Methods for conferring radiosensitivity to cells are also provided.

Abstract: Described are methods for protecting the female reproductive system against natural and artificial insults by administering to women a composition comprising an agent that antagonizes one or more acid sphingomyelinase (ASMase) gene products. Specifically, methods disclosed herein serve to protect women's germline from damage resulting from cancer therapy regimens including chemotherapy or radiotherapy. In one aspect, the method preserves, enhances, or revives ovarian function in women, by administering to women a composition containing sphingosine-1-phosphate, or an analog thereof. Also disclosed are methods to prevent or ameliorate menopausal syndromes and to improve in vitro fertilization techniques.

Abstract: The present invention relates, first, to methods for the modulation of acid sphingomyelinase (ASM)-related processes, including apoptosis. Such apoptosis can include, but is not limited to, environmental stress-induced apoptosis such as, for example, ionizing radiation and/or chemotherapeutic agent-induced apoptosis. Apoptosis can be characterized by a cellular morphology comprising cellular condensation, nuclear condensation or zeiosis. The present invention further relates to methods for the identification of compounds which modulate (i.e., either increase or decrease) sensitivity to ASM-related processes, including apoptosis.
