Silicosis is a scarring lung disease caused by inhaling fine particles of crystalline silica in the workplace of many industries. Due to the lack of effective treatment and management, the continued high incidence of silicosis remains a major public health concern worldwide, especially in the developing countries. Till now, related molecular mechanisms underlying silicosis are still not completely understood. Multiple pathways have been reported to be participated in the pathological process of silicosis, and more complex signaling pathways are receiving attention. The activated extracellular signal-regulated kinase (ERK) signaling pathway has been recognized to control some functions in the cell. Recent studies have identified that the ERK signaling pathway contributes to the formation and development of silicosis through regulating the processes of oxidative stress, inflammatory response, proliferation and activation of fibroblasts, epithelial-mesenchymal transformation, autophagy, and apoptosis of cells. In this review article, we summarize the latest findings on the role of ERK signaling pathway in silica-induced experimental models of silicosis, as well as clinical perspectives.
矽肺是一种瘢痕性肺部疾病,由许多行业工作场所中吸入结晶二氧化硅细颗粒所致。由于缺乏有效的治疗和管理方法,矽肺的持续高发病率仍是全球主要的公共卫生问题,在发展中国家尤为如此。到目前为止,矽肺相关的分子机制仍未完全明确。据报道,多种途径参与了矽肺的病理过程,并且越来越多复杂的信号通路受到关注。活化的细胞外信号调节激酶(ERK)信号通路已被认为可控制细胞中的某些功能。最近的研究表明,ERK信号通路通过调节氧化应激、炎症反应、成纤维细胞的增殖和活化、上皮-间质转化、自噬以及细胞凋亡等过程,促进矽肺的形成和发展。在这篇综述文章中,我们总结了ERK信号通路在二氧化硅诱导的矽肺实验模型中的作用的最新发现以及临床观点。
