Article Abstract

The intricate world of RNA modifications, collectively termed the epitranscriptome, covers over 170 identified modifications and impacts RNA metabolism and, consequently, almost all biological processes. In this review, we focus on the regulatory roles and biological functions of a panel of dominant RNA modifications (including m A, m C, Ψ, ac C, m A, and m G) on three RNA types-mRNA, tRNA, and rRNA-in mammalian development, particularly in the context of reproduction as well as embryonic development. We discuss in detail how those modifications, along with their regulatory proteins, affect RNA processing, structure, localization, stability, and translation efficiency. We also highlight the associations among dysfunctions in RNA modification-related proteins, abnormal modification deposition and various diseases, emphasizing the roles of RNA modifications in critical developmental processes such as stem cell self-renewal and cell fate transition. Elucidating the molecular mechanisms by which RNA modifications influence diverse developmental processes holds promise for developing innovative strategies to manage developmental disorders. Finally, we outline several unexplored areas in the field of RNA modification that warrant further investigation.

Testicular ageing is accompanied by a series of morphological changes, while the features of mitochondrial dysfunction remain largely unknown. Herein, we observed a range of age-related modifications in testicular morphology and spermatogenic cells, and conducted single-cell RNA sequencing on young and old testes in Drosophila. Pseudotime trajectory revealed significant changes in germline subpopulations during ageing.

RNA modifications are widespread throughout the mammalian transcriptome and play pivotal roles in regulating various cellular processes. These modifications are strongly linked to the development of many cancers. One of the most prevalent forms of RNA modifications in humans is adenosine-to-inosine (A-to-I) editing, catalyzed by the enzyme adenosine deaminase acting on RNA (ADAR) in double-stranded RNA (dsRNA).

N6-methyladenosine (m6A) modification: Emerging regulators in plant-virus interactions.

Electronic address:

N6-methyladenosine (m6A), a reversible epigenetic modification, is widely present on both cellular and viral RNAs. This modification undergoes catalysis by methyltransferases (writers), removal by demethylases (erasers), and recognition by m6A-binding proteins (readers), ultimately influencing the fate and function of modified RNA molecules. With recent advances in sequencing technologies, the genome-wide mapping of m6A has become possible, enabling a deeper exploration of its roles during viral infections.
