Overexpression of Mothers Against Decapentaplegic Homolog 7 Activates the Yes‐Associated Protein/NOTCH Cascade and Promotes Liver Carcinogenesis in Mice and Humans

Background and Aims Mothers against decapentaplegic homolog (SMAD) 7 is an antagonist of TGF‐β signaling. In the present investigation, we sought to determine the relevance of SMAD7 in liver carcinogenesis using in vitro and in vivo approaches. Approach and Results We found that SMAD7 is up‐regulated in a subset of human HCC samples with poor prognosis. Gene set enrichment analysis revealed that SMAD7 expression correlates with activated...
