Citrulline and atorvastatin‐induced changes in (A) phospho(Thr172)‐AMPKα/total AMPKα and (B) SREBP‐1 protein expression in human HuH7 hepatocarcinoma cells. (C) Western blot images of phospho(Thr172)‐AMPKα, total AMPKα and SREBP‐1 protein expression from (A) and (B). (D) l‐NAME, a NOS inhibitor, reduces citrulline and atorvastatin‐induced changes in phospho(Thr172)‐AMPKα/total AMPKα. * P < 0.05, significantly different from controls; $
P < 0.05, significantly different from control and other treated groups.
