Figure 2From: Susceptibility to ATP depletion of primary proximal tubular cell cultures derived from mice lacking either the α1 or the α2 isoform of the catalytic domain of AMPK Effect of metabolic stress on cytosolic ATP levels in MPT cells from α1 -/- and α2 -/- KO mice. MPT cells from α1-/- mice or α2-/- KO mice, or their WT controls, were subjected to graded ATP depletion by incubation in the presence of antimycin (2 μM) and varying concentrations of dextrose for 4 hrs. Cell ATP levels were measured and normalized to cell protein content. All values are expressed as a percent of ATP levels in MPT cells incubated under control conditions (10 mM dextrose, in the absence of antimycin). * p < 0.02, antimycin plus 10 mM dextrose vs. control conditions; # p < 0.01, antimycin plus 5 mM dextrose vs. antimycin plus 10 mM dextrose; p < 0.01, antimycin plus 2.5 mM dextrose vs. antimycin plus 5 mM dextrose.Back to article page
