Role of RNA modifications in blood development and regeneration

Rajesh Gunage et al. Exp Hematol. 2024 Oct.

Abstract

Blood development and regeneration require rapid turnover of cells, and ribonucleic acid (RNA) modifications play a key role in it via regulating stemness and cell fate regulation. RNA modifications affect gene activity via posttranscriptional and translation-mediated mechanisms. Diverse molecular players involved in RNA-modification processes are abundantly expressed by hematopoietic stem cells and lineages. Close to 150 RNA chemical modifications have been reported, but only N6-methyl adenosine (m6A), inosine (I), pseudouridine (Ψ), and m1A-a handful-have been studied in-cell fate regulation. The role of RNA modification in blood diseases and disorders is an emerging field and offers potential for therapeutic interventions. Knowledge of RNA-modification and enzymatic activities could be used to design therapies in the future. Here, we summarized the recent advances in RNA modification and the epitranscriptome field and discussed their regulation of blood development and regeneration.
