Effect of gensenoside Rg3 on apoptosis of Hep-2 and expression of HIF-1alha in human laryngeal cancer cell line under anoxic conditions



Effect of gensenoside Rg3 on apoptosis of Hep-2 and expression of HIF-1alha in human laryngeal cancer cell line under anoxic conditions



Zhong Yao Cai 32(1): 102-106



To study the mechanism and effect of gensenoside Rg3 on Hep-2 Cell Line during the normoxia and hypoxia. Hep-2 Human Laryngeal Cancer Cell Line was cultured under anoxic conditions, and set the normal control group and positive control group (DDP). MTT was used to observe the growth inhibition rates of Hep-2 Human Laryngeal Cancer Cell by Rg3; The cell cycle and cell apoptosis analysis were detected by FCM. Then the expression of HIF-1alpha and VEGF protein was detected by immunohistochemistry and FCM; The expression of HIF-1alpha and VEGF mRNA were detected by transcription-polymerase chain reaction (RT-PCR). Rg3 could significantly inhibit the growth of Hep-2 cells and arrest the cells in G0/G1 phase during normoxia and hypoxia The mRNA and protein expression of HIF-1alpha were dolon-regulated. Rg3 can inhibit Hep-2 cells growth by delaying the progress of cell cycle and inhibit the expression of HIF-1alpha during hypoxia, this may be the mechanism of its anti-tumor effect.
