Abstract

The aim of this article was to assess whether and how BARX1 affects the progression of malignant phenotype of endometrial carcinoma (EC) cells. BARX1 levels and its prognostic value were evaluated using the EC-related RNA sequence dataset from The Cancer Genome Atlas (TCGA) database. Functional experiments were performed to evaluate the biological roles of BARX1 in EC HEC-1-A and KLE cells by silencing BARX1. BARX1 was upregulated in EC tissues according to the public database and in EC cells. High expression of BARX1 led to a poor prognosis and significantly related to clinical stage, pathological grade, death, histological subtypes, and menopause status in patients with EC. Silencing BARX1 notably suppressed the aggressive phenotypes of EC cells, as evidenced by inhibiting cells viability, growth, invasion and migration. Furthermore, depletion of BARX1 decreased the phosphorylation (p) levels of ERK and MEK, also reinforced the suppressive effects of ERK/MEK pathway blocker PD98059 on the p-ERK and p-MEK levels. Together, our results demonstrated that BARX1 functions as a carcinogen by regulating the cell viability, invasion, and migration at least partly through the ERK/MEK pathway.
