A: MALDI-TOF mass spectrum generated from conditioned media collected after incubation of hGEnCs with 1 μM ANG II in the presence of 1 mM 1,10-phenanthroline alone (top) or the combination of 1 mM 1,10-phenanthroline and 1 mM DTT (bottom) for 4 h. Dashed box: quantitative inspection of ANG III (931 m/z) peaks using 10 nM AQUA-ANG III (937 m/z) as internal standard. B: quantification of observed differences at 4 h (average from 3 separate batches of cells). Values are means ± SE. *P < 0.01.
