GAPDH and nutritional disorder: Though this seems to disagree with prior studies which demonstrate that iron deficiency (Quail & Yeoh, 1995) and iron loading (Sheokand et al., 2014) could upregulate hepatocyte GAPDH, we posit that this inconsistency could be because (a) our mice were in a homeostatic steady‐state and that (b) their disparity in iron status did not reach a state of either iron deficiency or excess that had been associated with a change in GAPDH expression (Quail & Yeoh, 1995; Sheokand et al., 2014).
