Tripartite motif containing 59 (TRIM59) promotes esophageal cancer progression via promoting MST4 expression and ERK pathway

Abstract

Objective: To detect the expression of tripartite motif containing 59 (TRIM59) in human esophageal cancer (EC) tissues and explore whether TRIM59 could affect the progression of EC.Methods: Quantitative PCR and immunohistochemistry assays were performed to detect the expression of TRIM59 in 40 human EC tissues and corresponding non-tumor tissues. The correlations between TRIM59 expression and clinical pathological features of patients with EC were also investigated. CCK-8, colony formation, wound closure, and transwell assays were performed to detect the effects of TRIM59 on EC cells in vitro., Immunoblotting assays were performed to detect the effects of TRIM59 on the expression of mammalian sterile-20-like kinase 4 (MST4) and ERK pathway.Results: We reported increased expression of TRIM59 in human EC tissues, and its expression was correlated with clinical features, including metastasis (p = .011*) and maximum diameter (p = .027*), in patients with EC. We further found that TRIM59 contributed to the proliferation and invasion of EC cells via regulating mammalian sterile-20-like kinase 4 (MST4) expression and ERK pathway.Conclusion: Our data confirmed the involvement of TRIM59 in EC progression and proposed that TRIM59 could serve as a promising therapeutic target for the treatment of EC.
