The MetS-VLDL induced O-GlcNAcylation of Cx40 and Cx43. (a) The immunoblot shows increase in total O-GlcNAcylated Cx40 and Cx40 proteins in MetS-VLDL group. (b) Densitometry demonstrates that in the MetS-VLDL group, a significant increase in O-GlcNAcylation levels for both Cx40 and Cx43 (n = 4 for each group; 1.37 ± 0.26 folds to control, $P = 0.03 for Cx40 and 1.36 ± 0.15 folds to control, $P = 0.02 for Cx43).
