AIM: To construct recombinant lentiviral vector with short hairpin RNA( shRNA) of CREB gene,and to investigate the effect of CREB gene silencing on mitochondrial morphology and cell apoptosis in oxygen-glucose deprivation/reoxygenation( OGD/R)-induced cortical neurons. METHODS: Three lentiviral vectors pLenti Lox3. 7( PLL) inserted shRNA fragments targeting CREB gene were co-transfected with the packaging plasmids ps PAX2 and pMD2. G to the 293 T cells,and the virus particles,which was infected with the pri...
