Another study analyzed H19 expression levels in biliary atresia patients and found that H19 was upregulated in the liver of biliary atresia patients compared to healthy individuals, and the expression of H19 was correlated with the expression of fibrogenic markers αSMA and transforming growth factor beta 1 (TGF-β1) (37). The gene discussed is TGFB1; the disease is biliary atresia.
