mg/kg PP9对荷瘤裸鼠瘤体体积、瘤体质量、细胞核增殖相关抗原Ki-67、cleaved caspase-3蛋白表达的影响。结果 与对照组比较,
2、4 μmol/L PP9可显著降低细胞的克隆数和克隆形成率,显著升高其凋亡率和Fas、FasL、cleaved caspase-8、cleaved caspase-3蛋白
的表达水平(P<0.05或P<0.01);而联用KR-33493可显著逆转PP9对Fas/FasL信号通路相关蛋白表达的上调作用(P<0.01)。与
对照组裸鼠比较,PP9组裸鼠的瘤体体积(第27天)、瘤体质量、Ki-67蛋白的表达水平均显著降低,cleaved caspase-3蛋白的表达水平
显著升高(P<0.01)。结论 PP9可通过激活Fas/FasL信号通路来诱导肝癌HepG2细胞凋亡;同时,PP9还能有效抑制裸鼠移植瘤的

ABSTRACT OBJECTIVE To investigate the induction of apoptosis in hepatocellular carcinoma cells by polyphyllin 9 (PP9)
through the regulation of the Fas/Fas ligand (FasL) signaling pathway, and its inhibitory effect on the growth of transplanted tumor
in nude mice. METHODS Based on the screening of cell lines and intervention conditions, HepG2 cells were selected as the
experimental subject to investigate the effects of 2 μmol/L and 4 μmol/L PP9 treatment on cell colony formation activity, apoptosis
rate, as well as the protein expressions of Fas, FasL, cleaved caspase-8 and cleaved caspase-3. Additionally, Fas inhibitor KR-
33493 was introduced to investigate the underlying mechanism of PP9’s anti-hepatocellular carcinoma activity. Using HepG2 cell
tumor-bearing nude mice model as the object, and 5-fluorouracil (20 mg/kg) as the positive control, the effects of 10 mg/kg PP9
on tumor volume, tumor mass, and the protein expressions of the nuclear proliferation-associated antigen Ki-67 and cleaved
caspase-3 in tumor-bearing nude mice were investigated. RESULTS Compared with the control group, 2, 4 μmol/L PP9
significantly decreased the number of clones and the clone formation rate of cells, but significantly increased the apoptosis rate, the
protein expressions of Fas, FasL, cleaved caspase-8 and cleaved caspase-3 (P<0.05 or P<0.01). However, the combination of
Fas inhibitor KR-33493 could significantly reverse the effect of PP9 on the up-regulation of proteins related to the Fas/FasL
signaling pathway (P<0.01). Compared with the control group, the tumor volume (on day 27), mass and protein expression of Ki-
67 in nude mice of the PP9 group were significantly decreased, while the protein expression of cleaved caspase-3 was significantly
increased (P<0.01). CONCLUSIONS PP9 can induce
