Abstract:
Objective To investigate the effect of ketamine on c-fos gene expression in the glutamate induced injury of neuronal PC12 cells line. Methods The differentiated PC12 cells were seeded in 6-well plates(2?10~6/well) and incubated for 18 h,and then were randomly allocated to receive fresh medium(group C)or(10 mmol/L) glutamate(group G) or 0.1 mmol/L ketamine plus 10 mmol/L glutamate(group K1) or 0.5 mmol/L ketamine plus 10 mmol/L glutamate(group K2) or 1.0 mmol/L ketamine plus 10 mmol/L glutamate(group K3).At 5,15,30,60,120,240 and 360 min after administration of these drugs,the cells were collected respectively.(Total) cellular RNA was extracted.Reverse transcriptase-polymerase chain reaction was applied to determine cDNA amplification products with GAPDH mRNA as an internal control.Densities of DNA bands were quantified using the image analysis system.(Results)c-fos mRNA increased at 15 min,peaked at 30 min and 60 min,decreased at 120 min,reco-(vered) to the base level at 360 min among group G,K1 and K2.The c-fos mRNA levels were markedly elevated in group G as compared with the control levels(P
