Clinical significance of lncRNA XIST expression in cholangiocarcinoma and its effect on cell migration and invasion
Background
Cholangiocarcinoma is a malignant tumor that occurs in the bile duct system, and the prognosis of patients is poor. Currently, research suggests that long non-coding RNAs (lncRNAs) in the treatment and prevention of cholangiocarcinoma. This study primarily focuses on the regulation and potential mechanism of the lncRNA XIST (XIST) in cholangiocarcinoma.
Methods
The levels of XIST and miR-126–3p in cholangiocarcinoma tissues and cells were detected using real-time quantitative polymerase chain reaction (RT-qPCR). Cell transfection status, including migration and invasion, was examined via the Transwell method. The relationship between XIST and miR-126–3p was observed by dual-luciferase gene reporter assay and verified by rescue assays. Additionally, the prognostic significance of XIST in cholangiocarcinoma was determined using Kaplan-Meier and multivariate Cox regression analyses.
Results
XIST expression was increased in cholangiocarcinoma, while miR-126–3p was decreased, in both tissues and cells. The successful construction of silencing XIST was found to inhibit the count of cell migration and invasion. XIST directly targeted miR-126–3p to regulate the progression of cholangiocarcinoma.
Conclusion
XIST sponging miR-126–3p inhibited the progression of cholangiocarcinoma and improved the prognosis for patients. This finding provides new insights and opportunities for future studies on cholangiocarcinoma prognostic biomarkers.
期刊介绍：
Clinics and Research in Hepatology and Gastroenterology publishes high-quality original research papers in the field of hepatology and gastroenterology. The editors put the accent on rapid communication of new research and clinical developments and so called "hot topic" issues. Following a clear Editorial line, besides original articles and case reports, each issue features editorials, commentaries and reviews. The journal encourages research and discussion between all those involved in the specialty on an international level. All articles are peer reviewed by international experts, the articles in press are online and indexed in the international databases (Current Contents, Pubmed, Scopus, Science Direct).
Clinics and Research in Hepatology and Gastroenterology is a subscription journal (with optional open access), which allows you to publish your research without any cost to you (unless you proactively chose the open access option). Your article will be available to all researchers around the globe whose institution has a subscription to the journal.
