Regeneration is vital for many organisms, enabling them to repair injuries and adapt to environmental changes. The mechanisms underlying regeneration are complex and involve coordinated events at the cellular and molecular levels. Moreover, while some species exhibit remarkable regenerative capabilities, others, like mammals, have limited regenerative potential. Central to this process is the regulation of gene expression, and among the numerous genes involved, MYC emerges as a regulator of relevant processes during regeneration with roles conserved in several species, including . This mini-review aims to provide valuable insights into the regeneration process in flies, focusing on significant organs where the role of MYC has been identified: from the imaginal discs, where MYC regulates cell growth, structure, and proliferation, to the gut, where it maintains the balance between renewal and differentiation of stem cells, and the central nervous system, where it influences the activities of neural stem cells and the interaction between glia and neuronal cells. By emphasizing the molecular mechanisms regulated by MYC, its significance in controlling regeneration mechanisms, and its conserved role in flies, we aim to offer valuable insights into the utility of as a model for studying regeneration. Moreover, unraveling MYC's function in during regeneration may help translate findings into the mechanisms underlying human tissue repair.
再生对许多生物体至关重要,使它们能够修复损伤并适应环境变化。再生的潜在机制很复杂,涉及细胞和分子水平上的协同事件。此外,虽然一些物种具有显著的再生能力,但其他物种,如哺乳动物,再生潜力有限。这一过程的核心是基因表达的调控,在众多涉及的基因中,MYC在再生过程中作为相关过程的调节因子出现,其作用在包括……在内的几个物种中是保守的。本综述旨在深入了解果蝇的再生过程,重点关注已确定MYC作用的重要器官:从MYC调节细胞生长、结构和增殖的成虫盘,到其维持干细胞更新与分化平衡的肠道,以及其影响神经干细胞活性和神经胶质细胞与神经元细胞相互作用的中枢神经系统。通过强调由MYC调节的分子机制、其在控制再生机制中的重要性以及其在果蝇中的保守作用,我们旨在为将……作为研究再生的模型的实用性提供有价值的见解。此外,阐明MYC在……再生过程中的功能可能有助于将研究结果转化为人类组织修复的潜在机制。
