Figure 4. Activation of mitochondrial biogenesis by EPO is dependent on Akt and eNOS.
A. Cardiac mRNA expression for NRF-1 and PGC-1α in Wt mice at day 3 post-EPO is absent in eNOS -/- and Akt1-/- mice. B. Increases in Tfam mRNA and mtDNA copy number in Wt mice at day 3 post-EPO is absent in eNOS -/- and Akt1-/- mice. C. SOD2 mRNA expression in Wt mouse heart pre- and post- EPO (left), and pre- and at post-EPO day 3 in Wt, eNOS -/- and Akt1-/- mice relative to GAPDH (right) (* P<0.05 vs. control; n=4).
