	VEGFR1	VEGFR2	CD31	Tie-2	Ang-1	Ang-2	VEGF	HIF-1α
Cortex	54 ± 22	86 ± 16	170 ± 51	81 ± 23	71 ± 8	107 ± 17	146 ± 17	89 ± 15
Cerebellum	132 ± 38	120 ± 23	107 ± 23	90 ± 41	101 ± 21	94 ± 12	77 ± 6	101 ± 15
Hippocampus	133 ± 38	94 ± 19	108 ± 23	143 ± 50	62 ± 15	103 ± 17	65 ± 17	95 ± 19

Values are expressed as percent ± SEM of levels found in control littermates. No significant differences were found for any of the proteins evaluated.
