Figure 3.

Relative protein expression levels of PDH subunits analyzed by WB. Representative images of WB of the protein expression of PDH subunits E2, E3BP, E1α, and E1β (A) from cardiac tissue of controls and patients with HFrEF of ischemic (ICM) or non-ischemic (idiopathic) origin (IDC). Corresponding quantitative densitometry of protein expression of the PDH subunits E2, E3BP, E1α, and E1β (B) Protein values were normalized using the PDH V-chain complex. Points represent individuals (Control, n = 10; ICM, n = 9; IDC, n = 8) and mean ± standard deviation scatter cloud values are presented. *p < 0.05.
