Objective To explore the effect of silent CACUL1 expression on the proliferation of esophageal cancer cells and its mechanism. Methods Real-time quantitative PCR was used to detect the change of CACUL1 mRNA expression after transfection CACUL1 siRNA in EC109 cells. EC109 cell proliferation was determined by MTT assay. Cell cycle and apoptotic rate were analyzed by flow cytometry( FCM),and the expression of CDK2-Cyclin A/E protein was detected by Western blot method. Results CACUL1 mRNA and protein expressio...
