目的
2
探讨人参皂苷Rh
2
对人胶质瘤U87、U251细胞增殖、凋亡的影响及可能机制。
方法
2
以人胶质瘤U87、U251细胞为对象,经不同浓度的人参皂苷Rh
2
作用后,检测细胞的增殖、凋亡情况以及细胞中组蛋白脱乙酰酶1(HDAC1)蛋白和凋亡相关蛋白[B细胞淋巴瘤2(Bcl-2)、Bcl-2相关X蛋白(Bax)、切割型胱天蛋白酶3(cleaved caspase-3)
]
的表达情况。
结果
2
10、20、30、40、50、60、70、80 μmol/L的人参皂苷Rh
2
均能显著升高U87、U251细胞的增殖抑制率(
P
<0.05或
P
<0.01),该成分对2种细胞作用48 h的半数抑制浓度分别为51.34、55.84 μmol/L;30、50 μmol/L的人参皂苷Rh
2
均能显著升高2种细胞的总凋亡率,能显著降低HDAC1、Bcl-2蛋白的表达水平,并显著升高Bax、cleaved caspase-3蛋白的表达水平(
P
<0.05或
P
<0.01)。
结论
2
人参皂苷Rh
2
可抑制2种人胶质瘤细胞增殖并促进其凋亡,其作用可能与下调HDAC1蛋白的表达和激活Bcl-2家族蛋白介导的凋亡途径有关。
OBJECTIVE
2
To investigate the effects and mechanism of ginsenoside Rh
2
on the proliferation and apoptosis in human glioma U87 and U251 cells.
METHODS
2
Using human glioma U87 and U251 cells as subjects, the proliferation and apoptosis, as well as the expression of histone deacetylase 1 (HDAC1) protein and apoptosis-related proteins [B cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax) and cleaved caspase-3
]
were detected after being treated with different concentrations of ginsenoside Rh
2
.
RESULTS
2
The concentrations of 10, 20, 30, 40, 50, 60, 70, 80 μmol/L ginsenoside Rh
2
could generally significantly increase the proliferation inhibition rate of U87 and U251 cells (
P
<0.05 or
P
<0.01), and the half inhibitory concentrations of this component after 48 hours of action were 51.34 and 55.84 μmol/L, respectively; 30, 50 μmol/L ginsenoside Rh
2
could increase the total apoptotic rate of both types of cells, reduced the protein expressions of HDAC1 and Bcl-2, and increased the protein expressions of Bax and c
leaved caspase-3 significantly (
P
<0.05 or
P
<0.01).
CONCLUSIONS
2
Ginsenoside Rh
2
has a significant inhibitory effect on the proliferation of glioma cells and promotes the apoptosis of cells, which may be through reducing the expression of HDAC1 protein and activating the Bcl-2 family protein-mediated apoptosis pathway.
