胃癌中FOXOs基因表达与幽门螺杆菌感染的相关性及临床意义

Correlation Between FOXOs Genes Expression and Helicobacter Pylori Infection in Gastric Cancer and Its Clinical Significance

摘要

摘要:
目的探讨转录因子叉头框蛋白O（FOXOs）基因在胃癌组织中的表达及其与幽门螺杆菌（Hp）感染的相关性和临床意义。
方法免疫组织化学法检测41例Hp（−）和29例Hp（+）胃癌患者的癌组织、癌旁组织及30名健康者胃组织中FOXOs（包括FOXO1、FOXO3、FOXO4及FOXO6）基因的表达水平，分析其表达与Hp感染、临床病理特征的相关性，Kaplan-Meier plotter数据库分析其与胃癌患者生存预后的关系。
结果与Hp（−）胃癌组织相比，Hp（+）胃癌组织中FOXO1、FOXO4和FOXO6的表达水平偏高（P<0.05）；而 Hp（+）胃癌患者的癌组织中FOXO1、FOXO3和FOXO4表达水平却低于癌旁组织（P<0.05）及正常胃组织（P<0.0001）。FOXOs在胃癌组织中的表达率与胃癌分化程度、浸润深度、淋巴结转移和TNM分期等密切相关（P<0.05）。同时，FOXO1/3与胃癌患者生存预后有关。
结论 Hp感染促进胃癌组织中FOXO1/4/6的表达，抑癌基因FOXO1/4的高表达可能是Hp（+）的胃癌患者具有更好预后的原因之一；FOXOs基因广泛参与调控胃癌的疾病进程，这对疾病治疗具有一定价值。

Abstract:
Objective To investigate the expression of transcription factor forkhead box protein O (FOXO) genes in gastric cancer tissues and their correlation and clinical significance with Helicobacter pylori (Hp) infection.
Methods The expression levels of FOXOs genes (including FOXO1, FOXO3, FOXO4, and FOXO6) were detected by immunohistochemistry in cancer tissues and paracancerous tissues from 41 gastric cancer patients with Hp (−) and 29 gastric cancer patients with Hp (+) , as well as in gastric tissues from 30 healthy individuals. The correlation between FOXOs expression and Hp infection, clinical pathological features was analyzed. The relationship between FOXOs expression and survival prognosis of gastric cancer patients was analyzed using the Kaplan-Meier plotter.
Results Compared with those in the Hp(−) gastric cancer tissues, the expression levels of FOXO1, FOXO4, and FOXO6 were higher in the Hp(+) gastric cancer tissues (P<0.05). Meanwhile, the expression levels of FOXO1, FOXO3, and FOXO4 in the Hp(+) gastric cancer tissues were lower than that in the paracancerous tissues (P<0.05) and normal tissues (P<0.0001). The expression of FOXOs in gastric cancer tissues was closely correlated with the degree of differentiation, depth of infiltration, lymph node metastasis, and TNM stage of gastric cancer (P<0.05). Meanwhile, FOXO1/3 was associated with the survival prognosis of patients with gastric cancer.
Conclusion Hp infection promotes the expression of FOXO1/4/6 in gastric cancer tissues. The high expression of tumor suppressor genes FOXO1/4 may be one of the reasons for better prognosis in Hp (+) gastric cancer patients. FOXOs genes are widely involved in regulating the disease progression of gastric cancer, which has certain value for disease treatment.
