Objective To verify the genes screened by the polymerase chain reaction (PCR) chip of cell cycle. Methods The colon cancer cells SW480 were randomized into two groups, the test group (with gastrin stimulation) and con-trol group (without gastrin stimulation). The method of Western blot was used to detect the expression of calcylin binding pro-tein/Siah-1 interacting protein (Cacybp/SIP) before and after gastrin stimulation. The differential expression genes, cyclin de-pendent kinase 8 (CDK8) and cyclin dependent kinase subunit (CKS2), were verified by using real-time quantitative PCR (qRT-PCR). Results It was found that before the stimulation, CacyBP/SIP was located and expressed in cytoplasm, and then in both cytoplasm and nucleus after gastrin stimulation. The qRT-PCR results of CDK8 and CKS2 genes were consis-tent with those of microarray detection. The expressions of CDK8 and CKS2 were up-regulated (P < 0.05). Conclusion The stimulation of human gastrin can lead to the nuclear translocation of CacyBP/SIP. The results of microarray are reliable, and the differentially expressed genes screened through gene chip deserve further study.
