Biochem Biophys Res Commun:JNK1 /β-连环蛋白调节人晶状体上皮细胞中H2O2诱导发生的上皮-间质转化

2019-04-09 不详 网络

中山大学眼科学国家重点实验室的Li J等人近日在Biochem Biophys Res Commun杂志上发表了一篇研究性论文,他们发现暴露于低剂量(100μM)的H2O2会引起hLECs发生EMT,E-cadherin和ZO-1同时下调,而α平滑肌肌动蛋白(α-SMA)上调。

中山大学眼科学国家重点实验室的Li J等人近日在Biochem Biophys Res Commun杂志上发表了一篇研究性论文,他们发现暴露于低剂量(100μM)的H2O2会引起hLECs发生EMT,E-cadherin和ZO-1同时下调,而α平滑肌肌动蛋白(α-SMA)上调。

上皮-间质转化(EMT)是纤维化白内障的主要原因。最近研究显示,氧化应激可以引发人晶状体上皮细胞(hLEC)的上皮 - 间充质转变。但是,潜在的机制尚未完全理解。

他们研究发现,H2O2诱导的EMT伴随着磷酸化JNK1的积累。相反,通过siRNA敲低JNK1可逆转H2O2诱导发生的EMT。有趣的是,与正常晶状体囊相比,在白内障的人晶状体囊中JNK1、β-连环蛋白及其下游效应物细胞周期蛋白D和c-Myc的表达都显着提高。

因此,他们认为,活化的JNK1可以将β-连环蛋白从细胞膜上解离,随后转移至细胞核并引发下游因子的转录。细胞核β-连环蛋白、细胞周期蛋白D和c-Myc在H2O2诱导发生EMT过程中得到积累,并且在hLEC中降低JNK1的表达可以消除上述现象。

总之,他们研究表明JNK1通过介导β-连环蛋白的转运对hLECs中H2O2诱导的EMT至关重要。
