PDE5A Suppresses Proteasome Activity Leading to Insulin Resistance in C2C12 Myotubes
Figure 4
Effects of PDE5A on the proteasome activity in C2C12 myotubes. (a) Effects of PDE5A overexpression (OE) on the GFPu protein levels; (b) effects of PDE5A knockdown (KD) on the GFPu protein levels; (c) effects of PDE5A overexpression on the chymotrypsin-like activity of proteasome; (d) effects of PDE5A knockdown on the chymotrypsin-like activity of proteasome. (e) Representative western blots showing the effects of proteasome inhibitor MG132 on the GFPu protein levels; (f) quantification of the GFPu protein levels in (e). . , vs. the control group or the indicated group.
