Published in Women's Health Weekly, June 19th, 2008
Fresh data on cancer are presented in the report 'The PERK/eIF2 alpha signaling pathway of Unfolded Protein Response is essential for N-(4-hydroxyphenyl)retinamide (4HPR)-induced cytotoxicity in cancer cells.' "N-(4-hydroxyphenyl)retinamide (4HPR) is a synthetic retinoid that has been tested in clinical trials as a cancer chemopreventive drug. 4HPR is cytotoxic to cancer cells but the underlying molecular mechanisms are at present only partially understood. Here we demonstrate that in the human cervical cancer cell line HeLa and the human leukemia cell line HL-60, 4HPR caused rapid, Reactive Oxygen Species (ROS)-dependent activation of the Unfolded Protein Response (UPR)," scientists in...
