In the developing vertebrate retina, retinal progenitor cells (RPCs) proliferate and give rise to terminally differentiated neurons with exquisite spatio-temporal precision. Lineage commitment, fate determination and terminal differentiation are controlled by intricate crosstalk between the genome and epigenome. Indeed, epigenetic regulation plays pivotal roles in numerous cell fate specification and differentiation events in the retina. Moreover, aberrant chromatin structure can contribute to developmental disorders and retinal pathologies. In this review, we highlight recent advances in our understanding of epigenetic regulation in the retina. We also provide insight into several aspects of epigenetic-related regulation that should be investigated in future studies of retinal development and disease. Importantly, focusing on these mechanisms could contribute to the development of novel treatment strategies targeting a variety of retinal disorders.
在发育中的脊椎动物视网膜中,视网膜祖细胞(RPC)增殖,并以极高的时空精度产生终末分化的神经元。谱系决定、命运决定和终末分化受基因组和表观基因组之间复杂的串扰控制。事实上,表观遗传调控在视网膜中许多细胞命运特化和分化事件中发挥关键作用。此外,染色质结构异常可导致发育障碍和视网膜病变。在这篇综述中,我们强调了在视网膜中对表观遗传调控理解的最新进展。我们还深入探讨了一些与表观遗传相关的调控方面,这些方面应在未来的视网膜发育和疾病研究中进行研究。重要的是,关注这些机制可能有助于开发针对多种视网膜疾病的新型治疗策略。
