Cdk4 stability
WebMoreover, knockdown of CDK4 reversed the Cdc37-mediated effect in promoting the progression of CRC. Our findings showed that Cdc37 played a critical role in promoting CRC cell survival by increasing CDK4 stability to activate the RB1 signaling pathway. Thereby, Cdc37 might serve as a potential therapeutic target in CRC patients.
