Clinical sample validation revealed that EDIL3 expression was significantly elevated in BA liver tissue, and its high expression was significantly negatively correlated with the survival rate of patients' native livers.<h4>Conclusion</h4>Discoidin I-like domain 3 is a novel gene with a potentially key role in BA-related liver fibrosis, possibly influencing the proliferation and apoptosis of cholangiocytes by regulating the PI3K-AKT signaling pathway, thereby participating in the occurrence and development of liver fibrosis. The gene discussed is EDIL3; the disease is Hepatic fibrosis.
