ABSTRACT
Objective To investigate the expression of glucose transporter 3(GLUT 3) transcription level at different ischemic time in rats' focal cerebral ischemic penumbra and core of cortices.Methods Focal ischemic models of middle cerebral artery occlusion (MCAO) in rats were made by inserting nylon surgical thread. Brain samples were harvested from ischemic penumbra and core of cortices. The change of GLUT 3 mRNA was assessed by RT PCR.Results GLUT 3 mRNA in the penumbra regions slightly increased at 3 h after ischemia, and reached a peak at 24 h, in 96h following ischemia it came back to the normal level. As for ischemic core regions, GLUT 3 mRNA had a short time increase at 3 h after ischemia, and then rapidly decrease to the low level. Conclusion GLUT 3 mRNA expression was notably up regulated in the penumbra regions after focal cerebral ischemia,it may be a protective reaction against ischemic injury.
