The expression of VEGFA and HIF-1α was analyzed at 12h, 24h, 48h and 72h incubation time, respectively. We also accessed a GEO dataset of stroke to analyze in vivo the alteration of HIF-1α and VEGFA expression, and the correlations between HIF-1α, VEGFA and CD31 mRNA levels in vascular vessels after stroke.Results: VEGFA and HIF-1α expression were significantly higher in at each time point in the AdHIF-1α than other groups (p< 0.05), whereas the Ad group and hypoxia group, showed no statistically significant difference (p> 0.05). Moreover, VEGFA and HIF-1α levels were significantly higher in BMEC under hypoxia conditions than normoxia conditions (p < 0.05). Both HIF-1α and VEGFA expression significantly increased after stroke in vivo with 1.30 and 1.57 fold-change in log2, respectively. There were significantly positive associations between HIF-1α, VEGFA and CD31 mRNA levels in vivo after stroke.Conclusion: Hypoxia-induced HIF-1α and VEGFA expression in vascular vessels, and recombinant AdHIF-1α could up-regulate VEGFA, and enhance HIF-1ααlevels in BMEC in vitro, which may play an important role in the recovery of stroke.Keywords: AdHIF-1α, brain microvascular endothelial cells, hypoxia, VEGFA, strokeJin MLZou ZHTao TLi JXu JLuo KJLiu ZDove Medical Pressarticleadhif-1αbrain microvascular endothelial cellshypoxiavegfastrokeNeurosciences.
