Bim phosphorylation review

WebJan 30, 2009 · Treatment with calf intestinal phosphatase demonstrated that these alterations in Bim migration were due to phosphorylation and subsequent de-phosphorylation of Bim. Bim becomes hyper-phosphorylated during mitotic arrest (Fig. 2A, compare lanes 4 and 5) and undergoes de-phosphorylation as cells become apoptotic … WebJun 24, 2011 · Although cisplatin can induce ERK ( 25, 26) and ERK can phosphorylate Bim to target it for degradation, it is unclear thus far whether Bim degradation via cisplatin-induced ERK-mediated phosphorylation plays a role in cisplatin resistance, which is the focus of this study. In this study, we showed that cisplatin induces ERK activation, and …
