MLC1 and Familial prostate cancer: In literature, Western blot analysis on the phosphorylation of AKT on Ser-473 versus Thr-308 in PC-3 cells, a human prostate cancer cell line, and in MDA-MB-231 cells, a human breast cancer cell line, demonstrated that OSU-T315 selectively suppressed AKT phosphorylation on Ser-473, not on Thr-308, in a dose-dependent manner and this was accompanied by parallel decreases in the phosphorylation levels of GSK3β and MLC, two downstream targets of ILK [2].
