Fetal Programming and Sexual Dimorphism of Mitochondrial Protein Expression and Activity of Hearts of Prenatally Hypoxic Guinea Pig Offspring

Figure 4

Effects of prenatal hypoxia (HPX) on cardiac mitochondrial complex (I-V) expression of left ventricular heart tissue from male (a) and female (b) offspring. Hearts were obtained from offspring exposed to normoxia (NMX, open bars) or prenatal HPX (10.5% O₂, 14 d, hatched bars). Western immunoblots illustrate protein expression of representative subunits of Complexes I-V using an antibody cocktail.
