NRCMs were subjected to adenoviral overexpression of OGT and OGA. (A) Immunoblot for OGT and OGA protein expression following adenoviral treatment. (B) Immunoblot for protein O-GlcNAcylation demonstrated an induction of O-GlcNAc in response to Ad-OGT and a reduction in response to Ad-OGA. (C) Mitochondrial function assay of NRCMs 48 h post-transfection. Parameters of mitochondrial function were calculated from (C), including: (D) basal respiration, (E) maximal respiration, (F) reserve capacity, (G) ATP-linked respiration, and (H) proton leak. As indicated in bars, n = 5 independent experiments; *P < 0.05, compared with Ad-Null.
