Oxidative stress measurement under glycemia in vitro and in vivo. (A) ROS test by flow cytometry in HK2 cells in vitro. (B) Quantitation of ROS levels in HK2 cells. (C) MDA, (D) GSH, (E) SOD and (F) catalase concentration or IU in kidney tissues in normal control, DN-wild and DN NGAL-/- mice in vivo. NGAL, neutrophil gelatinase-associated lipocalin; HK2, human kidney 2; ROS, reactive oxygen species; MDA, malonaldehyde; GSH, glutathione; SOD, superoxide dismutase; DN, diabetic nephropathy; KD, knockdown; NC, negative control; HG, high glucose; NG, normal glucose.
