目的
2
探讨米托蒽醌脂质体(Lipo-MIT)对卵巢癌细胞增殖、迁移及癌症干细胞(CSCs)干性的影响,并基于磷脂酰肌醇3激酶(PI3K)/蛋白激酶B(AKT)通路探讨其作用机制。
方法
2
通过体外实验考察Lipo-MIT对细胞增殖、迁移和CSCs干性特征的影响。构建裸鼠人卵巢癌细胞A2780异种移植瘤模型,探究2、5 mg/kg Lipo-MIT对荷瘤裸鼠安全性以及体内肿瘤生长、肿瘤组织病理特征的影响,并考察Lipo-MIT对细胞与肿瘤组织中PI3K/AKT通路、上皮-间充质转化、干性相关蛋白表达的调控作用。
结果
2
Lipo-MIT对A2780、SK-OV3和OV-CAR5细胞的半数抑制浓度分别为0.72、5.41
、2.77 μmol/L;与溶剂对照(0.1%二甲基亚砜)比较,0.5~2.5 μmol/L Lipo-MIT可显著降低细胞克隆形成率、缩短细胞迁移距离、减少迁移细胞数、下调神经钙黏素(N-cadherin)蛋白表达、上调上皮钙黏素(E-cadherin)蛋白表达(
P
<0.05),并降低肿瘤球形成率、下调乙醛脱氢酶1A1(ALDH1A1)蛋白表达(
P
<0.05);1.0、2.5 μmol/L Lipo-MIT可显著降低干细胞成球概率和下调细胞中性别决定区Y框蛋白2表达(
P
<0.05)。2、5 mg/kg Lipo-MIT对荷瘤裸鼠的体重、饮食量和饮水量及脏器(心、肝、脾、肺、肾)指数均无明显影响(
P
>0.05),可显著改善肿瘤组织的病理变化,并可显著抑制肿瘤组织中N-cadherin和CD133、ALDH1A1(仅5 mg/kg Lipo-MIT)蛋白表达(
P
<0.05),上调E-cadherin(仅5 mg/kg Lipo-MIT)蛋白表达(
P
<0.05)。不同浓度/剂量Lipo-MIT均可显著降低细胞/肿瘤组织中PI3K、AKT蛋白的磷酸化水平(
P
<0.05)。
结论
2
Lipo-MIT可通过抑制PI3K/AKT通路活性来抑制卵巢癌细胞的增殖、迁移和干性。
OBJECTIVE
2
To investigate the effects of Mitoxantrone liposomes (Lipo-MIT) on the proliferation, migration and cancer stem cell (CSCs) stemness of ovarian cancer cells, as well as to explore its mechanism of action based on the phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT) pathway.
METHODS
2
The effects of Lipo-MIT on cell proliferation, migration and the stemness characteristics of CSCs were investigated through
in vitro
experiments. A human ovarian cancer A2780 cells xenograft tumor model of nude mouse was established to explore the effects of Lipo-MIT at doses of 2 and 5 mg/kg on the safety of tumor-bearing mice, as well as
in vivo
tumor growth and the pathological characteristics of tumor tissues. The influence of Lipo-MIT on the expression levels of PI3K/AKT pathway-related proteins, epithelial-mesenchymal transition related proteins, and stemness related proteins in both cells and tumor tissues was also investigated.
RESULTS
2
The half maximal inhibitory concentrations of Lipo-MIT against A2780, SK-OV3, and OV-CAR5 cells were 0.72, 5.41, and 2.77 μmol/L, respectively. Compared with solvent control (0.1% dimethyl sulfoxide), 0.5-2.5 μmol
/L Lipo-MIT significantly reduced the cell colony formation rate, shortened the cell migration distance, decreased the number of migrated cells, down-regulated the protein expression of N-cadherin, up-regulated the protein expression of E-cadherin (
P
<0.05), and also decreased the stem cell sphere formation frequency and down-regulated the protein expression of aldehyde dehydrogenase 1A1 (ALDH1A1) (
P
<0.05). Additionally, 1.0 and 2.5 μmol/L Lipo-MIT significantly reduced the stem cell sphere formation probability and down-regulated the protein expression of sex determining region Y box protein 2 in cells (
P
<0.05).
In vivo
experimental results demonstrated that 2, 5 mg/kg Lipo-MIT had no significant effects on the body weight, food intake, water intake, and organ (heart, liver, spleen, lung, and kidney) indices of tumor-bearing nude mice (
P
>0.05), but could significantly improve the pathological changes of tumor tissues and remarkably inhibit the protein expressions of N-cadherin, CD133 and ALDH1A1 (only at 5 mg/kg Lipo-MIT), up-regulate the expression of E-cadherin (only at 5 mg/kg Lipo-MIT) in tumor tissues (
P
<0.05). Lipo-MIT at different concentrations/doses significantly reduced the phosphorylation levels of PI3K and AKT proteins in cells/tumor tissues (
P
<0.05).
CONCLUSIONS
2
Lipo-MIT can inhibit the proliferation and migration of ovarian cancer cells and the stemness by suppressing the activity of the PI3K/AKT pathway.
