Densitometric analysis of selected myocardial enzymes and proteins involved in myocardial glucose metabolism in non-hypertrophied and hypertrophied hearts from male and female rats. (A) Enolase-α, (B) Enolase-β, (C) phosphofructokinase-1, and (D) pyruvate dehydrogeanse complex E1α subunit. White bar, male non-hypertrophied hearts; black bar, male hypertrophied hearts; light grey bar, female non-hypertrophied hearts; dark grey bar, female hypertrophied hearts. *, vs. sex-matched non-hypertrophied hearts (p < 0.05). $, vs. corresponding male hearts (p < 0.05). Values are expressed in arbitrary densitometry units, normalized to corresponding GAPDH densitometry units obtained from the same immunoblot. Numbers per group: 12 to 16 male non-hypertrophied hearts, 8 to 14 male hypertrophied hearts, and 6 to 8 female non-hypertrophied hearts, 6 to 8 female hypertrophied hearts. Values are mean ± SEM.
