目的
2
探讨秦皮乙素(Esc)通过调控蛋白激酶B(AKT)/S期激酶相关蛋白2(SKP2)/MutT同源酶1(MTH1)通路诱导急性髓系白血病(AML)HL-60细胞凋亡的作用。
方法
2
将HL-60细胞分为Control组(常规培养)、Esc低浓度组(L-Esc组,25 μmol/L Esc)、Esc中浓度组(M-Esc组,50 μmol/L Esc)、Esc高浓度组(H-Esc组,100 μmol/L Esc)、Esc高浓度+SC79(AKT激动剂)组(100 μmol/L Esc+5 μmol/L SC79)。采用MTT法和克隆形成实验检测细胞增殖能力;采用CM-H

DCFDA荧光探针法检测细胞中活性氧(ROS)水平;采用流式细胞术检测细胞凋亡情况;采用Western blot法检测细胞中凋亡相关蛋白[B细胞淋巴瘤2(Bcl-2)、Bcl-2相关X蛋白(Bax)、裂解的胱天蛋白酶3(cleaved caspase-3)
]
和AKT/SKP2/MTH1通路相关蛋白[磷酸化AKT(p-AKT)、AKT、SKP2、MTH1
]
及AKT上下游效应蛋白磷脂酰肌醇3激酶(PI3K)和周期蛋白依赖性激酶抑制剂1(P21)、周期蛋白依赖性激酶抑制剂1B(P27)的表达。
结果
2
与Control组相比,L-Esc组、M-Esc组、H-Esc组细胞的存活率、集落数以及AKT、PI3K蛋白的磷酸化水平和SKP2、MTH1、Bcl-2蛋白表达水平均显著降低(
P
<0.05),而ROS水平、细胞凋亡率和Bax、cleaved caspase-3、P21、P27蛋白表达水平均显著升高(
P
<0.05),且Esc的作用具有浓度依赖性
(
P
<0.05);与H-Esc组相比,Esc高浓度+SC79组细胞上述指标均被显著逆转(
P
<0.05)。
结论
2
Esc可能通过抑制AKT/SKP2/MTH1通路,促进HL-60细胞中ROS的大量产生及细胞凋亡程序的启动,最终有效抑制HL-60细胞增殖。
OBJECTIVE
2
To investigate the apoptosis-inducing effect of esculetin (Esc) on acute myeloid leukemia (AML) HL-60 cells by regulating the protein kinase B (AKT)/S-phase kinase-associated protein 2 (SKP2)/MutT homolog 1 (MTH1) pathway.
METHODS
2
AML HL-60 cells were randomly divided into control group (routine culture), Esc low-concentration group (L-Esc group, 25 μmol/L Esc), Esc medium-concentration group (M-Esc group, 50 μmol/L Esc), Esc high-concentration group (H-Esc group, 100 μmol/L Esc), and high-concentration of Esc+ SC79 (AKT agonist) group (100 μmol/L Esc+5 μmol/L SC79). Cell proliferation in each group was detected by MTT assay and colony formation assay. The level of reactive oxygen species (ROS) in cells was measured by using the CM-H

DCFDA fluorescent probe. Cell apoptosis was analyzed by flow cytometry. Western blot assay was performed to detect the expression levels of apoptosis-related proteins [B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein (Bax), cleaved caspase-3
]
, AKT/SKP2/MTH1 pathway-related proteins (p-AKT, AKT, SKP2, MTH1), along with the upstream and downstream proteins of AKT phosphatidylinositol 3-kinase (PI3K), cyclin-dependent kinase inhibitor 1 (P21) and cyclin-dependent kinase inhibitor 1B (P27).
RESULTS
2
Compared with control group, the cell viability, colony number, and the phosphorylation levels of AKT and PI3K proteins as well as protein expressions of SKP2, MTH1 and Bcl-2 were significantly decreased (
P
<0.05), while ROS level, apoptosis rate, and the expression levels of Bax, cleaved caspase-3, P21 and P27 proteins were significantly increased (
P
<0.05). Moreover, the effects of Esc ex
hibited concentration-dependence (
P
<0.05). Compared with H-Esc group, above indexes of high-concentration of Esc+SC79 group were reversed significantly (
P
<0.05).
CONCLUSIONS
2
Esc may promote massive ROS production and induce activation of apoptosis in HL-60 cells by inhibiting the AKT/SKP2/MTH1 pathway, thus inhibiting the proliferation of HL-60 cells.
