Collagen (Col) types I and III are integral components in wound healing and tissue regeneration, influencing tissue development, homeostasis, and related pathologies. Col I and Col III expression changes during different stages of wound healing and understanding the regulation of collagen phenotype determination is crucial for unraveling the complexities of these processes. Transcription factors and microRNAs, directly and indirectly, play a critical role in regulating collagen expression, however, a comprehensive understanding of the factors regulating Col I and III phenotypes remains elusive. This critically analyzed published reports with focuses on various factors regulating the expression of Col I and Col III at the transcriptional and translational levels. We performed bioinformatics analysis with an input of proinflammatory mediators, growth factors, elastases, and matrix metalloproteinases and predicted transcription factors and microRNAs involved in the regulation of collagen expression. Network analysis revealed an interaction between genes, transcription factors, and microRNAs and provided a holistic view of the regulatory landscape governing collagen expression and unveils intricate interconnections. This analysis lays a founda-tional framework for guiding future research and therapeutic interventions to promote extracellular matrix remodeling, wound healing, and tissue regeneration after an injury by modulating collagen expression. In essence, this scientific groundwork offers a comprehensive exploration of the regulatory dynamics in collagen synthesis, serving as a valuable resource for advancing both basic research and clinical interventions in tissue repair.
I型和III型胶原蛋白(Col)是伤口愈合和组织再生的重要组成部分,影响组织发育、体内平衡及相关病理过程。在伤口愈合的不同阶段,Col I和Col III的表达会发生变化,了解胶原蛋白表型决定的调控机制对于阐明这些过程的复杂性至关重要。转录因子和微小RNA直接或间接地在调节胶原蛋白表达中起关键作用,然而,对调节Col I和III表型的因素仍缺乏全面了解。本文对已发表的报告进行了批判性分析,重点关注在转录和翻译水平上调节Col I和Col III表达的各种因素。我们以促炎介质、生长因子、弹性蛋白酶和基质金属蛋白酶为输入进行了生物信息学分析,并预测了参与胶原蛋白表达调控的转录因子和微小RNA。网络分析揭示了基因、转录因子和微小RNA之间的相互作用,提供了胶原蛋白表达调控格局的整体视图,并揭示了复杂的相互联系。该分析为指导未来研究和治疗干预奠定了基础框架,通过调节胶原蛋白表达来促进损伤后的细胞外基质重塑、伤口愈合和组织再生。从本质上讲,这项科学基础工作全面探索了胶原蛋白合成中的调控动态,为推进组织修复的基础研究和临床干预提供了宝贵资源。
