In addition to the transforming growth factor (TGF-β1) signaling pathway, which is known to play major role in the activation of HSCs in liver fibrosis, many other pathways are implicated in liver fibrosis in NAFLD, such as the Hedgehog (Hh) [23,24], PI3K/AKT, and JAK/STAT/ERK signaling pathways [18]. The gene discussed is AKT1; the disease is Hepatic fibrosis.
