[1] Modulation of mcl-1 transcription by serum deprivation sensitizes cancer cells to cisplatin / V. V. Senichkin, G. S. Kopeina, E. A. Prokhorova et al. // Biochimica et Biophysica Acta - General Subjects. — 2018. — Vol. 1862, no. 3. — P. 557–566. The development of approaches that increase therapeutic effects of anti-cancer drugs is one of the most important tasks of oncology. Caloric restriction in vivo or serum deprivation (SD) in vitro has been shown to be an effective tool for sensitizing cancer cells to chemotherapeutic drugs. However, the detailed mechanisms underlying the enhancement of apoptosis in cancer cells by SD remain to be elucidated. RESULTS: We demonstrated that SD sensitizes cancer cells to treatment with chemotherapeutic agent cisplatin. This effect is independent on activation of caspases-2 and -8, apical caspases triggering apoptosis in response to genotoxic stress. SD potentiates cell death via downregulation of the anti-apoptotic protein Mcl-1. In fact, SD reduces the Mcl-1 mRNA level, which consequently decreases the Mcl-1 protein level and renders cells more susceptible to apoptosis induction via the formation of apoptosome. CONCLUSIONS: Mcl-1 protein is an important regulator of sensitivity of cancer cells to apoptotic stimuli upon SD. GENERAL SIGNIFICANCE: This study identifies Mcl-1 as a new target for the sensitization of human cancer cells to cell death by SD, which is of great significance for the development of efficient anti-cancer therapies.
