Abstract

The present study aimed to investigate the expression of methionine sulfoxide reductases B3 (MSRB3) in gastric cancer (GC) and its clinical significance. A total of 90 specimens from patients with GC were collected to evaluate MSRB3 protein expression by immunohistochemical staining. The associations between MSRB3 protein expression, clinicopathological characteristics and prognosis of patients with GC were subsequently investigated. The results demonstrated that MSRB3 protein expression in GC tissues samples was significantly higher compared with that in paired adjacent normal tissues (P=0.017). Among the 90 GC cases, 64 (71.1%) exhibited higher MSRB3 expression. In addition, the diagnostic value of MSRB3 for patients with GC was estimated with a sensitivity of 71.1% and a specificity of 46.7%. However, MSRB3 expression was not associated with clinicopathological characteristics of patients with GC. Kaplan‑Meier analysis indicated that patients with high MSRB3 expression had significantly shorter overall survival (OS) times compared with those with low expression (P=0.040). Univariate Cox regression analysis indicated that maximum tumor diameter, depth of invasion, lymph node metastasis, Tumor‑Node‑Metastasis (TNM) stage and MSRB3 expression were significantly associated with OS time. Multivariate Cox regression analysis indicated that MSRB3 was an independent predicting factor for the OS time of patients with GC (P=0.049). In addition, analysis using The Cancer Genome Atlas (TCGA) database validated these results. Kaplan‑Meier analysis revealed that higher MSRB3 mRNA expression was associated with poorer OS time in 442 patients with GC (P=0.004). Univariate analysis of the TCGA data indicated that age, depth of invasion, lymph node metastasis, distant metastasis, TNM stage and MSRB3 expression were significantly associated with OS time; however, sex and histological differentiation were not associated with OS time. Multivariate analysis demonstrated that MSRB3 was an independent prognostic factor in patients with GC (P=0.001). In conclusion, these results demonstrated that MSRB3 expression was upregulated in patients GC, which suggests that MSBR3 may serve as a potential prognostic biomarker.
