Figure Lengend Snippet: TGF-β signaling in Cav-1-deficient hepatocytes. In the absence of Cav-1, TβRs delocalize between the membrane and the cytoplasm, leading to a TGF-β-deficient signaling. Lesser activated Smad2/3 translocates to the nucleus, and the higher levels of SnoN impair the transcription of growth-arrest genes and enhance hepatocyte proliferation in the process of liver regeneration. In the presence of Cav-1, TGF-β signaling is sufficient to maintain the balance between cell proliferation and cell growth arrest characteristic of regenerating liver.
