Abstract:
Objective To investigate the apoptosis of cultured normal human hepatocyte HL-7702 cells induced by glycodeoxycholate(GCDC)and to explore its possible mechanism.Methods HL-7702 cells were incubated with various concentrations(100,150,200 and 250 ?mol/L)of GCDC.The changes of cellular morphology were observed under optical microscope.The apoptosis rate of HL-7702 was determined by Annexin V-FITC/PI double staining.The changes of HL-7702 cell intracelluar \[Ca2+\]i were determined with Fluo-3/AM load technique.The mRNA expression levels of Bcl-2/Bax in HL-7702 cells were analyzed by RT-PCR.Results Typical apoptotic morphological changes were observed after HL-7702 cells had been treated with 150 ?mol/L GCDC for 24 h;HL-7702 cells could be induced to undergo apoptosis in a concentration-dependent manner after 100,150,200,and 250 ?mol/L GCDC treatment for 24 hours.The apoptosis rates were(13.16?2.9)%,(20.3?3.0)%,(25.02?2.1)% and(45.02?3.5)%,which were markedly higher(P
