Methods: Apoptosis-related indicators and PML-RARA expression were determined to investigate the effect of GRh2 on NB4 cells. Z-VAD-FMK,LY294002和C 87作为caspase的抑制剂,以及磷脂酰肌醇3-激酶(PI3K)和肿瘤坏死因子-α(TNF-α)途径用于澄清GRH2诱导的ppoptosis and Pml-Rara rara rara rara degradation degradation pred 结果: grh2剂量和时间依赖性降低NB4细胞的生存能力。经过12小时的处理后,NB4细胞中GRH2诱导的凋亡,细胞周期停滞和CASPASE3,CASPASE8和CASPASE9激活。 GRH2诱导的NB4细胞凋亡伴随着反应性的大量产生氧,线粒体损伤和上调BAX/BCL-2表达。 GRH2还诱导了NB4细胞中下游p53途径的PML/PML-RARA降解,PML核体形成和激活。 Z-VAD-FMK抑制了caspase的激活,并显着逆转了GRH2诱导的凋亡和PML-RARA降解。 GRH2还上调TNF-α表达并抑制Akt磷酸化。 LY294002, an inhibitor of the PI3K pathway, enhanced the antitumor effects of GRh2, and C 87, an inhibitor of the TNF-α pathway, reversed NB4 cell viability, and GRh2-mediated apoptosis in a caspase-8-dependent manner. Conclusion: GRH2通过AKT/BAX/CASPASE9和TNF-α/CASPASE8途径引起NB4细胞中caspase依赖性PML-RARA降解和凋亡。
