Acquired cellular resistance to traditional chemotherapeutics is a common obstacle in the treatment of most cancer cell types. This resistance occurs as a result of changes in the underlying molecular mechanisms of disease progression. The development of novel chemotherapeutic approaches designed to enhance the efficacy of protypical anti-cancer drugs is important in order to overcome this issue. Such approaches will aid in understanding the biomolecular phenomena responsible for drug resistance and disease progression. Combining signaling pathway inhibitors has become an effective strategy for enhancing tumor cell death by targeting multiple pathways known to regulate cell survival. Pemetrexed, an FDA-approved anti-folate …

Interleukin-7 (IL-7) is an essential cytokine for lymphocyte growth that has the potential for promoting proliferation and survival. While the survival and proliferative functions of IL-7 are well established, the identities of IL-7 signaling components in pathways other than JAK/STAT, that accomplish these tasks remain poorly defined. To this end, we used IL-7 dependent T-cells to examine those components necessary for cell growth and survival. Our studies revealed two novel signal transducers of the IL-7 growth signal: BimL and JunD. IL-7 promoted the activity of JNK (Jun N-terminal Kinase), and that JNK, in turn, drove the expression of JunD, a …
