: Magmas, a gene encoding for the mitochondrial import inner membrane translocase subunit, Tim16, protects different cell lines from the antitumoral effects of several pro-apoptotic stimuli (i.e. chemicals and chemotherapeutic agents). The synthetic Compound 5 is capable of sensitizing chemoresistant tumor cells overexpressing Magmas to proapoptotic stimuli, indicating that this molecule may be useful to overcome tumor chemoresistance. The aim of our study was to evaluate whet...

TIM16 a component of the translocase complex TIM23 of the mitochondrial inner membrane is encoded by the Magmas gene. Magmas was found to be over-expressed in human pituitary adenomas. Silencing Magmas in ACTH secreting rat pituitary adenoma cells enhances sensitivity to pro-apoptotic stimuli. Moreover, Magmas overexpression protects GH secreting rat pituitary adenoma cell lines towards apoptosis. Recently, we found that compound 5, a TIM16 inhibitor, is not cytotoxic but enha...
