Abstract
<sec> <title>Objective:</title> This study was designed to probe the influence and mechanism of lncRNA HOTAIR on migration, apoptosis and proliferation of hepatocellular carcinoma (HCC) cells. </sec> <sec> <title>Methods:</title>
We evaluated LncRNA HOTAIR expression in HCC tissues and adjacent tissues, and serum of HCC patients and healthy controls. Later, we knocked down lncRNA HOTAIR, and utilized CCK-8 to determine Hep3B cell proliferation, flow cytometry for prospecting Hep3B cell apoptosis, and cell scratch
assay for observing Hep3B cell migration.We anticipated the direct target of lncRNA HOTAIR, and adopted luciferase reporter assay to verify. Moreover, we inhibitedmiR-126-5p expression, and rescue experiment for evaluating the influence of si-HOTAIR+miR-126-5p inhibitors on Hep3B cell migration,
apoptosis as well as proliferation. </sec> <sec> <title>Results:</title> Our results showed that lncRNA HOTAIR expression in tumor tissues and serum was significantly increased. Moreover, lncRNA HOTAIR inhibition significantly decreased the Hep3B cell proliferation
rate, elevated Hep3B cell apoptosis rate, and inhibited Hep3B cell migration. Luciferase reporter assay suggested that miR-126-5p was the direct target of lncRNA HOTAIR. Furthermore, co-transfection of si-HOTAIR+miR-126-5p inhibitor could diminishthe effects of HOTAIR silencing on apoptosis,
proliferation and migration. </sec> <sec> <title>Conclusion:</title> Silencing of lncRNA-HOTAIR can inhibit the HCC cell migration and proliferation, and increase the apoptosis by up-regulating miR-126-5p expression. </sec>
