Objective :To study the role of P44/42MAPK on the apoptosis of adrenocortical cells of rat induced by Triptolide. Methods :Adrenocortical cells of rats were dispersed primarily in vitro,with different concentration gradients of Triptolide poisoning at the same time,or in the same concentration of Triptolide poisoning at different time points,using combined labeling with annexin-V and propidium iodide(PI)and flow cytometry,the protein imprinting method analysis to detect the total protein,phosphorylation lev...
