Long non-coding ribonucleic acid W5 inhibits progression and predicts favorable prognosis in hepatocellular carcinoma. | LitMetric

AI Article Synopsis

Article Abstract

Background: Accumulating evidence has revealed that several long non-coding ribonucleic acids (lncRNAs) are crucial in the progress of hepatocellular carcinoma (HCC).

Aim: To classify a long non-coding RNA, ., lncRNA W5, and to determine the clinical significance and potential roles of lncRNA W5 in HCC.

Methods: The results showed that lncRNA W5 expression was significantly downregulated in HCC cell lines and tissues. Analysis of the association between lncRNA W5 expression levels and clinicopathological features suggested that low lncRNA W5 expression was related to large tumor size ( < 0.01), poor histological grade ( < 0.05) and serious portal vein tumor thrombosis ( < 0.05). Furthermore, Kaplan-Meier survival analysis showed that low expression of lncRNA W5 predicts poor overall survival ( = 0.016).

Results: Gain-of-loss function experiments, including cell counting kit8 assays, colony formation assays, and transwell assays, were performed to investigate the biological roles of lncRNA W5. experiments showed that ectopic overexpression of lncRNA W5 suppressed HCC cell proliferation, migration and invasion; conversely, silencing of lncRNA W5 promoted cell proliferation, migration and invasion. In addition, acting as a tumor suppressor gene in HCC, lncRNA W5 inhibited the growth of HCC xenograft tumors .

Conclusion: These results showed that lncRNA W5 is down-regulated in HCC, and it may suppress HCC progression and predict poor clinical outcomes in patients with HCC. LncRNA W5 may serve as a potential HCC prognostic biomarker in addition to a therapeutic target.
