Figure 4From: A possible role for AMP-activated protein kinase activated by metformin and AICAR in human granulosa cells The phosphorylation of pI κ B. The phosphorylation of pIκB in KGN cells treated with TNF-α (1nM) and metformin (1 mM) (n = 4). A: The phosphorylation of pIκB was quantified against GAPDH. B: Representative blots illustrating the effect of treatment on pIκB and GAPDH by metformin for 15 min. The blot layout is in the same order as the graph in B.Back to article page
