Objects Firstly to explore impaction on rat liver cell line BRL-3A proliferation exerted by TGF-β1, further use lentivirus expressing shRNA targeted to smad3 gene to silent SMAD3 of BRL-3 A,which is an important downstream protein of TGF-β1/smads pathway, then survey proliferation difference between BRL-3A and BRL-3 A infected by lentivirus again,besides study its action mechanisms preliminary, laying foundations for further studies of accelerating liver regeneration based on TGF-β1 pathway.
