GPR116 overexpression correlates with poor prognosis in gastric cancer

Abstract

The G protein-coupled receptor 116 (GPR116) is an adhesion subtype of the G protein-coupled receptor family and has been reported to be involved in tumorigenesis and cancer progression. Moreover, it has been shown to predict poor prognosis in breast and colorectal cancers. However, little is known about the role of GPR116 in gastric cancer (GC). In this study, we aimed to investigate the expression and clinical prognostic significance of GPR116 in GC.The mRNA expression levels of GPR116 in GC were analyzed using Gene Expression Omnibus and UALCAN databases, and GPR116 protein expression in GC tissues was detected using immunohistochemistry. The relationship between GPR116 expression and prognosis in patients with GC was analyzed and further validated using the Kaplan–Meier Plotter database. The correlation between GPR116 and the differentially expressed genes identified was analyzed using the LinkedOmics database. Gene set enrichment analysis was performed using WebGestalt. The results revealed that GPR116 expression was significantly upregulated in GC tissues, which was positively correlated with tumor node metastasis (TNM) staging and tumor invasion. Prognostic analysis suggested that high GPR116 expression contributed to poor overall survival in GC patients. Multivariate Cox analysis indicated that GPR116 overexpression was an independent prognostic indicator in patients with GC (HR = 1.855, 95% CI 1.021–3.370, P = .043). Enrichment analysis showed that GPR116 co-expression genes were mainly involved in extracellular matrix-receptor interaction, focal adhesion, cell adhesion, PI3K-Akt signaling, DNA replication, and cell cycle pathways. In conclusion, GPR116 was highly expressed in GC tissues and associated with poor prognosis in patients with GC, Thus GPR116 may be a novel prognostic marker and a potential therapeutic target for GC treatment.

Polysaccharide of Lactobacillus casei SB27 reduced colon cancer cell prognosis through mitochondrial damage by upregulation of HINT2

“…The occurrence and development of tumors are determined by many factors, including the relative activity of proto oncogenes and tumor suppressor genes, immune microenvironment, and inflammatory microenvironment 16 . The pro‐inflammatory nature of prognosis is related to the pathogenesis of many chronic inflammatory diseases 17,18 . Therefore, the inflammatory microenvironment formed by the release of a large number of inflammatory factors in the process of prognosis may promote the occurrence and development of tumors 16 .…”

Biomarker discovery with quantum neural networks: a case-study in CTLA4-activation pathways

“…GPR116 has been reported to be involved in cancer progression and predicts poor prognosis in other types of cancer. The study [91] shows that GPR116 expression is upregulated in gastric cancer (GC) tissues and is positively correlated with tumor invasion and poor prognosis. GPR116 may be a novel prognostic marker and a potential therapeutic target for GC treatment.…”
