Wnt myofibroblastic activation of hepatic stellate cells (WP3649)

This pathway is modeled after figure 5 from Kweon et al. The WNT signaling pathway activates Beta-catenin which inhibits serine and cysteine proteases. This inhibition of these proteins increases MeCP2 stability and induces epigenetic repression of Ppar-y leading to hepatic stellate cell myofibroblastic activation causing liver fibrosis which can lead to liver cirrhosis.
