Ankrd33 Is Overexpressed In Gastric Adenocarcinoma And Predictive For Poor Prognosis

The aim of the current study was to investigate and discuss the function of ANKRD33 gene in the pathogenesis of gastric adenocarcinoma. The marked up-regulated expression of ANKRD33 gene in gastric adenocarcinoma tissues compared to normal tissues was found by bioinformatics analysis. Kaplan-Meier analysis revealed that high expression of ANKRD33 is correlated with lower overall survival of gastric adenocarcinoma patients. The results of qPCR revealed that mRNA expression level of ANKRD33 was dramatically higher in AGS, SGC7901, and BGC823 cell lines than that in the GES1 cells. Knockdown of ANKRD33 remarkably inhibited the viability, invasion, and migration of AGS and BGC823 cells. Furthermore, the ratio of p-AKT/AKT and p-mTOR/mTOR was significantly decreased in AGS cells which transfected with si- ANKRD33. All the above results illustrated that ANKRD33 would act as a tumor forwarder in gastric adenocarcinoma development and have a high potential to be a marker molecule in the diagnosis and treatment of gastric tumors.
