Overexpression of IC53d promotes the proliferation of gastric cancer cells by activating the AKT/GSK3β/cyclin D1 signaling pathway. Oncol Rep. 2019 Mar 05;: Authors: Lin JX, Xie XS, Weng XF, Qiu SL, Xie JW, Wang JB, Lu J, Chen QY, Cao LL, Lin M, Tu RH, Li P, Huang CM, Zheng CH Abstract Cyclin‑dependent kinase 5 regulatory subunit‑​associated protein 3 (CDK5RAP3 or C53) is involved in the development of various types of tumor, and alternative splicing of C53 results in numerous transcription variants that encode different isoforms. The present study aimed to clone human C53 isoform d (IC53d) and explore its role in the proliferation of gastric cancer cells. Reverse transcription‑quantitative polymerase chain reaction was used to detect the expression levels of IC53d in 80 primary gastric adenocarcinoma tissues and adjacent normal tissues. In addition, the association between IC53d and clinicopathological parameters was determined. Gastric cancer cell lines stably overexpressing IC53d were established to observe its effects on cell proliferation, invasion and migration, and on in vivo tumorigenicity, and the mechanism of action was explored. The results of the presen study demonstrated that IC53d was upregulated in gastric cancer tissues and was associated with tumor T‑stage. Furthermore, overexpression of IC53d promoted the proliferation, colony formation and G1/S phase transition of gastric cancer cells, leading to enhanc...
