摘要

Growing research indicates that long noncoding RNAs (lncRNAs) are pivotal in the development and advancement of hepatocellular carcinoma (HCC). Our research pinpointed LINC01547 as a notable lncRNA that was significantly downregulated in Hep3B cells treated with bufotalin, whereas it exhibited elevated expression levels in HCC tumor tissues. Further study found that silencing LINC01547 markedly suppressed proliferation, induced apoptosis, and inhibited migration and invasion in Hep3B and HepG2 cells. LINC01547 knockdown reduced ADAR1 expression, which led to apoptosis and suppressed metastasis via inhibition of the FAK signaling pathway. Additionally, silencing LINC01547 upregulated miR-146b-5p, which in turn decreased RAC1 levels, further promoting apoptosis and inhibiting metastasis in HCC cells. In vivo, a Hep3B tumor-bearing mouse model confirmed the antitumor effects of LINC01547 silencing. Our findings demonstrate that LINC01547 regulates HCC cell apoptosis and metastasis through the ADAR1/FAK and miR-146b-5p/RAC1 pathways, suggesting that LINC01547 may serve as a biomarker and potential therapeutic target for HCC.
