Abstract
N6-methyladenosine (m6A), a reversible and dynamic RNA modification, plays pivotal roles in regulating stem cell pluripotency and early embryogenesis. Disruptions in m6A homeostasis lead to profound developmental defects, impairing processes such as stem cell self-renewal, lineage specification, oocyte maturation, zygotic genome activation, and maternal RNA degradation after fertilization. Beyond its well-recognized roles in mRNA transport, stability, and translation, recent studies have highlighted m6A’s critical role in transcriptional regulation through intricate RNA–chromatin interactions, notably involving chromatin-associated regulatory RNAs (carRNAs) and retrotransposon RNAs. This review delves into the dynamic regulatory landscape of m6A, highlighting its critical interplay with chromatin modifications, and explores its broader implications in stem cell biology and early embryonic development.
期刊介绍:
Current Opinion in Genetics and Development aims to stimulate scientifically grounded, interdisciplinary, multi-scale debate and exchange of ideas. It contains polished, concise and timely reviews and opinions, with particular emphasis on those articles published in the past two years. In addition to describing recent trends, the authors are encouraged to give their subjective opinion of the topics discussed.
In Current Opinion in Genetics and Development we help the reader by providing in a systematic manner:
1. The views of experts on current advances in their field in a clear and readable form.
2. Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications.[...]
The subject of Genetics and Development is divided into six themed sections, each of which is reviewed once a year:
• Cancer Genomics
• Genome Architecture and Expression
• Molecular and genetic basis of disease
• Developmental mechanisms, patterning and evolution
• Cell reprogramming, regeneration and repair
• Genetics of Human Origin / Evolutionary genetics (alternate years)
