The vitamin A metabolite, retinoic acid, is an important signaling molecule during embryonic development serving critical roles in morphogenesis, organ patterning and skeletal and neural development. Retinoic acid is also important in postnatal life in the maintenance of tissue homeostasis, while retinoid-based therapies have long been used in the treatment of a variety of cancers and skin disorders. As the number of people living with chronic disorders continues to increase, there is great interest in extending the use of retinoid therapies in promoting the maintenance and repair of adult tissues. However, there are still many conflicting results as we struggle to understand the role of retinoic acid in the multitude of processes that contribute to tissue injury and repair. This review will assess our current knowledge of the role retinoic acid signaling in the development of fibroblasts, and their transformation to myofibroblasts, and of the potential use of retinoid therapies in the treatment of organ fibrosis.
维生素 A 的代谢产物视黄酸是胚胎发育过程中的一种重要信号分子,在形态发生、器官模式形成以及骨骼和神经发育中起着关键作用。视黄酸在后生生活中对于维持组织内环境稳定也很重要,而基于维甲酸的治疗方法长期以来一直用于治疗各种癌症和皮肤疾病。随着患有慢性疾病的人数不断增加,人们对延长维甲酸疗法的应用以促进成人组织的维持和修复产生了浓厚的兴趣。然而,在我们努力理解视黄酸在促进组织损伤和修复的多种过程中的作用时,仍然存在许多相互矛盾的结果。这篇综述将评估我们目前对视黄酸信号在成纤维细胞发育及其向肌成纤维细胞转化中的作用的认识,以及视黄酸疗法在治疗器官纤维化中的潜在用途。
