Silcening YWHAE gene expression suppresses the proliferation of colon cancer cells by inducing gene differentially expressed.

In this study,YWHAE expression was silenced by RNA interference in colon cancer cell lines, and investigate the correlation between YWHAE expression and colon cancer proliferation,and differential expressed genes were analized by gene assay and qPCR technologe.The proliferation and colony formation ability of colon cancer cells were significantly reduced after YWHAE knockdown. More 1200 known genes were found to be involved in the YWHAE functions related tumorigenesis by genechip analysis, these genes related to cell proliferation/apoptosis and cell cycle process. qRT-PCR results showed an expression pattern consistent with that of the genechip analysis. Lentivirus-mediated RNA interference was used to knockdown YWHAE expression in colon cancer cell lines. And cell proliferation assays . GeneChip analysis were carried out for mRNA expression profiling, followed, the expressed levels of mRNA and protein were measured by Quantitative real-time polymerase chain reaction (qRT-PCR) and western blot , respectively.
