Cell Cycle Target-Based Therapy of Ovarian Cancer
Abstract
In many tumors, the actively dividing cells account for only a small proportion of the total, with the remainder of the cells being in a quiescent state or G0. Indeed, tumor cell population in G0 ranges from 70-95% and the quiescent cell population of tumors poses a barrier to the success of many cancer therapies. Numerous studies demonstrate that non-steroidal antiinflammatory drugs (NSAIDs) hold significant promise as anti-cancer therapeutics. We started identifying now the best of NSAIDs therapy for apoptosis induction of quiescent ovarian cancer cells. In this report we show that structurally unrelated NSAIDS induces apoptosis in quiescent ovarian cancer cells. Strong inducers of apoptosis included flufenamic acid, flurbiprofen, celebrex and finasteride, whereas treatment with ibuprofen in low levels of apoptosis. Additionally, the spectrum of NSAIDs obtained in this analysis differs from the spectrum of NSAIDs obtained by our group for induction of apoptosis in proliferative ovarian cancer cells. Our results offer a multitude of novel entry points for drug development and will provide opportunities for a rational design of new combination treatment modalities for ovarian cancer.
