Research Abstract

Hyoxia-inducible factor 1(HIF-1) is a transcription factor that regulates the adaptive response to hypoxia in mammalian cells. It consists of a regulatory subunit HIF-1α, which accumulates under hypmic conditions, and constitutively expressed subunit, HIF-1β. We investigated HIF-1α naked DNA-induced angiogenesis in a cerebral ischemic model in vivo. We utilized a rat encephalo-myo-synangiosis model and inoculated HIF-1α naked DNA on the brain surface or temporal muscle. We analyzed HIF-1α induced angiogenic factors and collateral circulation. A histological section treated with HIF-1α DNA showed an increased expression of HIF-1α and VEGF with collateral circulation, in comparison with control DNA HIF-1α transcription factor is able to promote significant angiogenesis development.
Geranylgeranylacetone (GGA) is known as an antinuclear agent and more recently as a heat shock protein (HSP) inducer. This study evaluated the neuroprotective effect of GGA against cerebral infarction induced by permanent left middle cerebral artery (MCA) occlusion in rats. GGA was given orally in various regimens prior to MCA ocdusion Pretreatment with a single oral GGAdose (800 mg/kg) 48 hours before ischemia significantly attenuated cerebral infarction volume. A significant increase in HSP70 immunoreactivity was found in the neocortex in GGA-treated animals with or without ischemia. Pretreatment with a single oral dose of GGA provides an important tool for exploring the mechanisms of neuroprotection against cerebral ischemic neuronal damage.
