摘要:

目的 探究胸腺素β10(thymosin β10, TMSB10)在胃癌中的表达及促进胃癌进展的分子机制。 方法 收集蚌埠医学院第二附属医院70例胃癌患者病理切片,免疫组化检测TMSB10在胃腺癌中的表达,并分析其预后影响。为研究作用机制,通过转染技术、CCK8实验、EDU实验、Transwell小室实验,划痕实验,糖酵解实验,蛋白印迹实验,观察TMSB10对胃癌细胞的增殖和糖酵解的影响及机制研究。 结果 临床样本免疫组化显示,TMSB10在胃癌中高表达。同时,TMSB10的表达水平与肿瘤大小(P < 0.05)、TNM分期(P < 0.01)和远处转移具有相关性。在机制研究中,通过体外实验CCK-8、EDU实验、Transwel实验及糖酵解检测实验发现过表达TMSB10后促进胃癌细胞增殖、侵袭、迁移及糖酵解表型,反之亦然。Western blot实验结果显示过表达TMSB10可能通过上调AMPK/mTOR信号通路调节胃癌的发生。 结论 TMSB10通过AMPK/mTOR信号通路促进胃癌细胞增殖、侵袭、迁移及糖酵解过程。

Abstract:

Objective To investigate the expression of Thymosinβ10 (TMSB10) in gastric cancer and its molecular mechanism in promoting the progression of gastric cancer. Methods We collected pathological sections of 70 patients with gastric cancer in our hospital, detected expression of TMSB10 in gastric adenocarcinoma by immunohistochemistry, and analyzed its prognostic effect. In order to study the mechanism of action, the effects of TMSB10 on the proliferation and glycolysis of gastric cancer cells and its related mechanism were observed by transfection technique, CCK8 test, EDU assay, Transwell assay, scratch test, glycolysis assay and Western blot. Results Immunohistochemistry showed that TMSB10was highly expressed in gastric cancer, while the expression level of TMSB10 was correlated with tumor size (P = 0.032), TNM stage (P = 0.002) and distant metastasis. In the mechanism study, we found that overexpression of TMSB10 promoted the proliferation, invasion, migration and glycolytic phenotype of gastric cancer cells through in vitro CCK-8 test, EDU assay, Transwel assay and glycolysis assay, and vice versa. Western blot results showed that overexpression of TMSB10 may regulate the occurrence of gastric cancer through up-regulation of the AMPK/mTOR signaling pathway. Conclusions TMSB10 promotes the proliferation, invasion, migration and glycolysis gastric cancer through the AMPK/mTOR signaling pathway.
