Abstract
TLR8-AS1 has been characterized as an oncogenic lncRNA in ovarian cancer, while its role in hepatocellular carcinoma (HCC) is unknown. This study aimed to explore the role of TLR8-AS1 in HCC. TLR8-AS1 expression in HCC and paired non-tumor tissues from 62 HCC patients was determined by RT-qPCR. The prognostic value of TLR8-AS1 for HCC was analyzed by performing a 5-year follow-up. Correlations between TLR8-AS1 and mature miR-34a and miR-34a precursor were analyzed by Pearson's correlation coefficient. The roles of TLR8-AS1 and miR-34a in regulating the proliferation and migration were explored by CCK-8 assay and Transwell migration assay. We found that TLR8-AS1 was upregulated in HCC and predicted poor survival. Across HCC tissues, TLR8-AS1 was inversely correlated with mature miR-34a, but not miR-34a precursor. In HCC cells, TLR8-AS1 overexpression downregulated mature miR-34a, but not miR-34a precursor. Cell proliferation and Transwell migration assay showed that TLR8-AS1 overexpression reduced the enhancing effects of miR-34a on cell proliferation and migration. TLR8-AS1 may suppress miR-34a maturation in HCC to suppress cell proliferation and migration.Entities:
