Figure 6. AICAR- and SFM-induced GAPDH translocation in AMPKα-knockout MEFs. (A and B) Normal and AMPKα-null MEF cells (AMPKα1^−/−, AMPKα2^−/−, and AMPKα1^−/−/α2^−/−) were cultured in 10% FBS medium for 2 days and then treated with 1 mM AICAR (A) or SFM (B) for 2 days. Cells were immunostained with a GAPDH-specific antibody and analyzed by confocal laser scanning microscopy. The number of cells having nuclear GAPDH with or without cytosolic GAPDH was counted, and the percentage distributions were calculated (n = 10 and 20 for total replicates in A and B, respectively) and plotted as means +/− standard deviations. ^**p < 0.01 and ^***p < 0.001, compared with the normal value in the absence of AICAR or SFM (−), ^##p < 0.01 and ^###p < 0.001, compared each value in the presence (+) to that in the absence of AICAR or SFM (−).
