Objective To observe the effects of CoC12 treatment on the expression of Hypoxia-inducible factor-1(HIF-1α) in mice hippocampus at different time point.Methods Balb/c mice were injected with CoCl2 and the change of HIF-1 α was detected by western blot and immunofluorescence and confocal laser scanning microscope at different time point(0h,1h,2h,3h,4h,5h and 6h) after injection.Results The relative protein level of HIF-1α was 0.135 ±0.01,0.572 ±0.01,0.595 ±0.03,1.09 ±0.03,1.30 +0.04,1.275 ±0.03,0.947 ±0.03respectively at different time point after the injection.The HIF-1α protein level reached its peak value at 4 h and decreased at 5h and 6h.Fluorescence intensity of HIF-1α was 13.33 ± 3.42,30.95 ± 7.86,46.50 ± 9.65,61.50± 10.02,88.30 + 15.69,71.39 ± 11.28,67.41 ± 10.78 respectively at different time point after the injection.The HIF-1α fluorescence intensity also reached its peak value at 4 h and decreased at 5h and 6h.Conclusion Time dependent HIF-1α accumulation was in close correlation with the CoCl2.
