Impacts of PM on the expression of autophagy-associated proteins and mRNA were determined by western blotting and RT-qPCR in HK-2 cells. β-actin was used as an internal control. Expression of (A, B) Beclin-1, (C, D) LC-3II, and (E, F) P62 was determined by western blotting and RT-qPCR. NG – normal glucose, 5.5 mM glucose; HG – high glucose, 30 mM glucose; NG+PM – PM (1 mM) plus 5.5 mM glucose; HG+PM – PM (1 mM) plus 30 mM glucose. (#

P<0.01 compared with NG. * P<0.05, ** P<0.01 compared with the HG group). PM – pyridoxamine; RT-qPCR – reverse transcription-quantitative polymerase chain reaction; HK-2 – human proximal tubular epithelial cells.
