The transition of fibroblasts to myofibroblasts (FMT) represents a pivotal process in wound healing, tissue repair, and fibrotic diseases. This intricate transformation involves dynamic changes in cellular morphology, gene expression, and extracellular matrix remodeling. While extensively studied at the molecular level, recent research has illuminated the regulatory roles of non-coding RNAs (ncRNAs) in orchestrating FMT. This review explores the emerging roles of ncRNAs, including microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), in regulating this intricate process. NcRNAs interface with key signaling pathways, transcription factors, and epigenetic mechanisms to fine-tune gene expression during FMT. Their functions are critical in maintaining tissue homeostasis, and disruptions in these regulatory networks have been linked to pathological fibrosis across various tissues. Understanding the dynamic roles of ncRNAs in FMT bears therapeutic promise. Targeting specific ncRNAs holds potential to mitigate exaggerated myofibroblast activation and tissue fibrosis. However, challenges in delivery and specificity of ncRNA-based therapies remain. In summary, ncRNAs emerge as integral regulators in the symphony of FMT, orchestrating the balance between quiescent fibroblasts and activated myofibroblasts. As research advances, these ncRNAs appear to be prospects for innovative therapeutic strategies, offering hope in taming the complexities of fibrosis and restoring tissue equilibrium.
成纤维细胞向肌成纤维细胞的转变(FMT)是伤口愈合、组织修复和纤维化疾病中的一个关键过程。这种复杂的转变涉及细胞形态、基因表达和细胞外基质重塑的动态变化。虽然在分子水平上已进行了广泛研究,但最近的研究揭示了非编码RNA(ncRNA)在协调FMT中的调节作用。本综述探讨了ncRNA,包括微小RNA(miRNA)、长链非编码RNA(lncRNA)和环状RNA(circRNA),在调节这一复杂过程中的新作用。ncRNA与关键信号通路、转录因子和表观遗传机制相互作用,以在FMT过程中微调基因表达。它们的功能对于维持组织稳态至关重要,而这些调节网络的破坏与各种组织中的病理性纤维化有关。了解ncRNA在FMT中的动态作用具有治疗前景。靶向特定的ncRNA有可能减轻过度的肌成纤维细胞活化和组织纤维化。然而,基于ncRNA的疗法在递送和特异性方面仍存在挑战。总之,ncRNA在FMT的交响乐中成为不可或缺的调节因子,协调静止成纤维细胞和活化肌成纤维细胞之间的平衡。随着研究的进展,这些ncRNA似乎是创新治疗策略的前景,为驯服纤维化的复杂性和恢复组织平衡带来了希望。
