摘要:

目的:探究柚皮素(NAR)通过PI3K/AKT/NF-κB通路抑制卵巢癌细胞增殖、凋亡和侵袭能力的机制。方法:体外培养卵巢癌细胞,并分为空白组、低剂量柚皮素组、中剂量柚皮素组和高剂量柚皮素组;使用柚皮素预处理后,检测NAR对卵巢癌细胞增殖、凋亡、侵袭及迁移的影响情况;检测细胞侵袭迁移及凋亡相关蛋白和PI3K/AKT/NF-κB通路相关蛋白的表达情况。结果:使用柚皮素处理后,各组卵巢癌细胞增殖、迁移、侵袭受到显著抑制,凋亡受到显著促进,且对柚皮素呈剂量依赖性。相比空白组,使用柚皮素各组PCNA、Bcl-2、N-cadherin、MMP-9、MMP-2蛋白水平显著降低(P<0.01),Bax、Caspase-3、E-cadherin、PI3K蛋白表达水平及AKT、p65磷酸化水平显著升高(P<0.01),且随着柚皮素使用剂量的增加呈剂量依赖性,总AKT蛋白表达无显著变化(P>0.05)。结论:NAR可能通过抑制EMT及PI3K/AKT/NF-κB通路抑制卵巢癌细胞增殖和侵袭能力,并促进卵巢癌细胞的凋亡,在一定剂量范围内呈剂量依赖性。

Abstract:

AIM: To investigate the mechanism of naringenin (NAR) inhibiting the proliferation, apoptosis and invasion ability of ovarian cancer cells by PI3K/AKT/NF-κB pathway. METHODS: Ovarian cancer cells were cultured in vitro. They were divided into blank group (Control), low-dose NAR group, medium-dose NAR group and high-dose NAR group. After pretreatment with NAR, effects of NAR on proliferation, apoptosis, invasion and migration of ovarian cancer cells were detected. The expression of invasion, migration and apoptosis related proteins and PI3K/AKT/NF-κB pathway-related proteins was detected. RESULTS:The proliferation, migration and invasion of ovarian cancer cells were significantly inhibited in groups treated with NAR, while apoptosis was significantly promoted, showing dose-dependence to NAR. Compared with blank group, levels of PCNA, Bcl-2, N-cadherin, MMP-9 and MMP-2 protein were significantly decreased in the groups treated with NAR (P<0.01), while expression levels of Bax, Caspase-3, E-cadherin and PI3K protein, phosphorylation level of AKT and p65 were significantly increased (P<0.01). With increase of NAR dose, there was dose-dependence. There was no significant change in total AKT protein expression (P>0.05). CONCLUSION: NAR may inhibit proliferation and invasion ability of ovarian cancer cells by inhibiting EMT and PI3K/AKT/NF-κB pathway, and promote apoptosis of ovarian cancer cells, showing dose-dependence within a certain dose range.
