esophageal squamous cell carcinoma; lncRNA Erbb4-IR; miR-145
Erbb4-IR is a recently identified lncRNA with pivotal functions in renal injury. The present study investigated the roles of Erbb4-IR in esophageal squamous cell carcinoma (ESCC). It was observed that Erbb4-IR was upregulated in tumor tissues of patients with ESCC. Plasma levels of Erbb4-IR in patients with ESCC were positively correlated with expression levels of Erbb4-IR in tumor tissues. MicroRNA-145 (miR-145) was downregulated in tumor tissues and inversely correlated with Erbb4-IR only in tumor tissues. Erbb4-IR overexpression led to downregulated miR-145, and increased rates of ECSS cell proliferation and decreased rates of ECSS cell apoptosis. Overexpression of miR-145 showed no significant effects on Erbb4-IR expression, but played an opposite role on cancer cell proliferation and apoptosis. In addition, miR-145 overexpression attenuated the effects of Erbb4-IR overexpression. Therefore, lncRNA Erbb4-IR may promote ESCC by downregulating miR-145.
