Elevation of microRNA-214 is associated with progression of liver fibrosis in patients with biliary atresia

Study identifies elevated microRNA-214 levels in liver tissue and serum as a predictor of severe fibrosis in biliary atresia patients post-Kasai procedure. Serum miR-214 demonstrates potential as a non-invasive biomarker for monitoring fibrosis progression, with cut-off value showing strong predictive accuracy for advanced disease stages.
