着色性干皮病补体组C (XPC)蛋白是核苷酸切除修复中重要的DNA损伤识别因子。XPC的缺失与人类肺癌发生的早期阶段有关,XPC mRNA水平的降低预示着非小细胞肺癌(NSCLC)患者预后不良。然而,肺癌中XPC表达缺失与不良预后之间的联系机制尚不清楚。在这里,我们报告了XPC沉默通过下调E-Cadherin来驱动NSCLC细胞增殖和迁移的证据。在具有上皮表型的非小细胞肺癌中,XPC敲除增强增殖和迁移,同时降低E-Cadherin的表达。在体外和体内实验中,E-Cadherin在这些细胞中的恢复抑制了XPC敲低诱导的细胞生长。机制研究表明,XPC缺失通过激活ERK通路和上调Snail表达来抑制E-Cadherin的表达。我们的研究结果表明,XPC沉默诱导的E-Cadherin表达的降低,至少在一定程度上是低XPC表达的NSCLC患者预后不良的原因。
Xeroderma pigmentosum complementation group C (XPC) protein is an important DNA damage recognition factor in nucleotide excision repair. Deletion of XPC is associated with early stages of human lung carcinogenesis, and reduced XPC mRNA levels predict poor patient outcome for non-small cell lung cancer (NSCLC). However, the mechanisms linking loss of XPC expression and poor prognosis in lung cancer are still unclear. Here, we report evidence that XPC silencing drives proliferation and migration of NSCLC cells by down-regulating E-Cadherin. XPC knockdown enhanced proliferation and migration while decreasing E-Cadherin expression in NSCLC cells with an epithelial phenotype. Restoration of E-Cadherin in these cells suppressed XPC knockdown-induced cell growth both in vitro and in vivo. Mechanistic studies showed that the loss of XPC repressed E-Cadherin expression by activating the ERK pathway and upregulating Snail expression. Our findings indicate that XPC silencing-induced reduction of E-Cadherin expression contributes, at least in part, to the poor outcome of NSCLC patients with low XPC expression.
