Abstract Objective To investigate the effect of all-trans retinoic acid (ATRA) on related genes CD133,Sox2 and GSK3B of gastric cancer stem cells in order to find a new starting point for the treatment of gastric cancer.Methods Human gastric cancer xenografts in nude mice were divided into control group, 5-FU group, ATRA group and 5-FU+ATRA group. After intraperitoneal injection of ATRA, the general condition of nude mice were observed before the tumor-bearing mice were sacrificed to remove the tumor tissue. HE staining was used to detect gastric cancer cell necrosis of the tissue. The expression of CD133mRNA, Sox2mRNA and GSK3BmRNA was detected using semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) and real-time quantitative PCR analysis while immunohistochemistry was adopted to detect the expression of CD133, Sox2 protein and GSK3B.Results Compared with the control group, the tumor shrank in 5-Fu group, ATRA group, and 5-Fu+ATRA group. The difference was significant (P<0.05). The expressions of CD133, Sox2 stem cell-related factors were high in 5 -Fu group, ATRA group, and 5-Fu+ATRA group. However, there was significant difference in GSK3B expression between ATRA group and 5-Fu+ATRA group, (P<0.05).Conclusions After the administration of ATRA, gastric cancer stem cell markers, such as CD133 and Sox2, have a higher expression. The increased expression of CD133, Sox2 and GSK3B might inhibit the growth of tumor cells. The new use of ATRA can contribute to the prognosis of gastric cancer.
