Expression of protein kinase C in multidrug resistant cells of colorectal carcinoma / 吉林大学学报(医学版)

ABSTRACT

Objective To detect the expression of protein kinase C(PKC) in multidrug resistant cells of colorectal carcinoma after ionizing irradiation and observe the effect of PKC on occurrence and development of the multidrug resistant.Methods The effect of PKC on multidrug resistant HCG-8 cells of colorectal carcinoma after treated with X-ray was detected by indirect immunofluorescence technique and flow cytometry.Results Compared with sham-irradiation group,the positive percentage of PKC was increased significantly(P
