Immunostaining for YAP, apoptosis marker (TUNEL), fibrosis markers (sirius red and aSMA), progenitors (K19) and osteopontin, from representative liver sections from wild-type mice fed chow diet (n=7), Western diet (n=8) or methionine-choline deficient (MCD)-diet (n=6). YAP staining is graphed as Mean±SEM. **P<0.01, chow versus NASH-inducing diets, ##P<0.01, Western versus MCD diet. Correlations between YAP immunostaining and the above immunohistochemistries as well as mRNA expression.
