Figure 3. The optimum concentration of LRG was investigated and the knockdown cell model of AMPKa was constructed in H19-7 cell line. (A) The optimum concentration of LRG was investigated in cell level by incubating cells with different concentrations of LRG (0, 50, 75, 100, 125, and 150 nM); (B) Knockdown of AMPKa in cell level was constructed. *p < 0.05.
