Abstract
Long noncoding RNA, RNA component of mitochondrial RNA processing endoribonuclease (RMRP) plays an important role in cancer development and is closely correlated with prognosis in cancer patients. However, whether RMRP affects prognosis in patients with hepatocellular carcinoma (HCC) remains unclear. The aim of the present study was to investigate the expression level of RMRP in HCC and its correlation with prognosis in patients with HCC and explain the effects and associated mechanisms by conducting an in vitro study. The high expression level of RMRP was correlated with poor prognosis in patients with HCC. Using in vitro analysis, RMRP knockdown suppressed HCC cell proliferation, invasion, and migration (P < .05). miRNA-206 overexpression had similar effects in HCC cell lines (Bel-7402 and Huh-7). Using Western blot analysis and cellular immunofluorescence detection, RMRP downregulation significantly suppressed TACR1/Erk1/2 pathway, while miRNA-206 was significantly upregulated (P < .05). RMRP downregulation inhibits HCC-related biological activities by the regulation of miRNA-206/TACR1.Entities:
