    AbstractThe long noncoding RNAs (lncRNAs) are widely involved in the progression of various malignant tumors. The current study investigated the role and mechanism of lncRNA melanoma highly expressed noncoding RNA (MHENCR) in colorectal carcinoma. The expression of MHENCR was measured by real-time quantitative reverse transcription PCR (RT-qPCR). The chi-square analysis was used to analyze the correlation between MHECNR and miR-532-3p. Kaplan-Meier curve and multivariate Cox regression analysis were conducted to assess the significance of MHENCR in clinic. The interaction of MHENCR and miR-532-3p was probed using Pearson analysis and dual-luciferase reporter assay. Cellular experiments were implemented to explore the effects of MHENCR/miR-532-3p on colorectal carcinoma cells. Compared with para-cancerous tissues, MHENCR expression was increased and miR-532-3p expression was decreased in tumor tissues. High expression of MHENCR exhibited shorter overall survival. Interfering of MHENCR suppressed cellular activities while the silence of miR-532-3p diminished the decreased cellular behaviors in colorectal carcinoma cells. Interfering with MHENCR expression represses colorectal carcinoma cell proliferation, migration, and invasion by regulating miR-532-3p. MHENCR may act as a novel prognostic marker in colorectal carcinoma and MHENCR/miR-532-3p may serve as a potential target for treating colorectal carcinoma.
