    ..These results indicate that chronic inflammation associated with HCV infection shifts hepatocytic TGF-beta signaling from tumor-suppression to fibrogenesis, accelerating liver fibrosis and increasing risk for HCC. ..

    ..This review addresses TGF-?/Smad signal transduction in chronic liver injuries and carcinogenic processes. We also discuss the reversibility of Smad signaling after antiviral therapy. ..

    ..Based on these findings, we have reason to hope that pharmacologic inhibition of linker phosphorylation might suppress progression to human advanced carcinomas by switching from protumorigenic to tumor-suppressive TGF-? signaling. ..
