LncRNA MIR22HG abrogation inhibits proliferation and induces apoptosis in esophageal adenocarcinoma cells via activation of the STAT3/c-Myc/FAK signaling
Long non-coding RNAs (IncRNAs) have involved in human malignancies and played an important role in gene regulations. The dysregulation of IncRNA MIR22HG has been reported in several cancers. However, the role of MIR22HG in esophageal adenocarcinoma (EAC) is poorly understood. Loss of function approaches were used to investigate the biological role of MIR22HG in EAC cells. The effects of MIR22HG on cell proliferation were evaluated by WST-1 and colony formation assays. The effects of MIR22HG on cell migration and invasion were examined using transwell assays. QRT-PCR and Western blot were used to evaluate the mRNA and protein expression of related genes. In this study, abrogation of MIR22HG inhibited cell proliferation, colony formation, invasion and migration in EAC 3 cell lines (OE33, OE19 and FLO-1). Mechanistically, MIR22HG silencing decreased the expression of STAT3/c-Myc/p-FAK proteins and induced apoptosis in EAC cell lines. These results delineate a novel mechanism of MIR22HG in EAC, and may provide potential targets by developing IncRNA-based therapies for EAC.
