Protein expression of VEGF isoforms in left ventricular myocardium by duration of intermittent hypoxia. (a) Representative images of cardiac VEGF₁₈₈, VEGF₁₆₄, and VEGF₁₂₀ in the left ventricle quantified by Western blot with normalization against GAPDH (N = 4/group). (b) Densitometry analysis of VEGF₁₂₀. *different from normoxia (p = 0.01) and IH‐1 (p = 0.03). (c) Densitometry analysis of VEGF₁₆₄. *different from normoxia (p < 0.001) and IH‐1 (p = 0.01). (d) Densitometry analysis of VEGF_188, no significant changes found. Results are expressed as mean ± SEM in arbitrary units
