ABSTRACT
Objective To investigate the association between SERPINH1 gene expression in gastric cancer tissue with the pathology and prognosis and its action mechanism in gastric cancer.Methods The gastric cancer data in the TCGA and GEO public databases were collected,and the retrospective analysis and survival analysis were conducted on the SERPINH1 expression data of the tumor tissue samples and related clinical information;the gene set enrichment analysis(GSEA) was used to analyze the SERPINH1 expression related functional gene sets and to investigate the SERPINH1 action mechanism.Results In 421 cases of gastric cancer sample,the SERPINH1 expression level had no significant differences with the tumor grade,N stage and metastasis.However,its high expression was significantly correlated with the tumor invasion depth(T stage)(P=0.049).The higher the expression level,the preater the invasion depth.In the survival analysis,the patients with high SERPINH1 expression showed a poorer prognosis than those with low SERPINH1 expression[P<0.001,HR(95%CI)1.97 (1.61-2.41)].The gene set enrichment analaysis found that the related gene sets such as tumor signal pathway and tumor microenvironment were enriched in the SERPINH1 high expression samples.The gene expression chip data in 69 cases of gastric cancer and paracancerous tissue also suggested that SERPINH1 was highly expressed in gastric cancer (P<0.000 1) with a greater diagnostic value (AUC=0.988 1).Conclusion High expression of SERPINH1 is correlated with the occurrence and development of gastric cancer,and has a greater clinical significance.
