This article highlights the importance of the recent study by Grohmann et al. published in the November, 2018 issue of Cell. It contributes to the understanding of molecular mechanisms which relate obesity with NASH and HCC. This study highlights the respective roles of STAT-1 signaling in inducing NASH and fibrosis and of STAT-3 in promoting HCC formation. Probably the most relevant finding is that STAT-3 signaling can drive tumor onset in a context of obesity with NAFLD, independently of the presence of NASH and fibrosis.
