In a study by Yu et al., they showed that the serum miR-17-5p levels of patients with cirrhosis were significantly higher than those of healthy controls, and that the inhibition of this miRNA led to the suppression of hepatic stellate cell proliferation induced by transforming growth factor-β1 (TGF-β1) [33]. The gene discussed is TGFB1; the disease is Cirrhosis.
