VEGF protein expression. (a) There were no changes in VEGF levels with hypoxia alone in either wildtype or HIF-1α knockout. (b) There also were no significant changes in VEGF levels after HI, although there was a trend toward an increase in the HIF-1α knockout 15 min after HI (p=0.11). (c) There was no change in VEGF expression in HPc/HI mouse cortex in either wildtype or HIF-1α knockout. White columns are wildtype. Black columns are HIF-1α knockout.
