Differential gene expression profiles. mRNA levels of (A) angiogenic-associated genes; (B) antioxidant genes; and (C) transcription factors were measured using PCR arrays and compared between WT (black line, n = 3), wHet (gray bar, n = 3), and hHet (white bar, n = 3) placentas. All levels were normalized to Gapdh and Actb levels.
