Fold change in expression of VEGFR2 mRNA, relative to β-actin, at p0, p14 and p18 room air (RA) and 50/10 OIR. Significantly increased fold expression in VEGFR2 mRNA was present in 50/10 OIR compared to RA at p18 (*p=0.004). A trend toward increased fold expression of VEGFR2 in 50/10 OIR was noted at p14 (p=0.06). Student t-tests.
