To investigate the role of HIF-1α in SH-SY5 Y cell injury induced by quinolinic acid, SH-SY5 Y cells were divided into control group, quinolinic acid low, medium and high dosage groups and HIF-1α inhibitor(2ME2) pretreated group; the cell viability was determined by MTT reduction assay and LDH assay; cell apoptosis was determined by Hoechst 33342 staining; the intracellular distribution of HIF-1α was examined by HIF-1α immunostaining and the expressions of HIF-1α, Akt, p-Akt, Bcl-2 and Bax were determined b...
