M6A eraser ALKBH5/treRNA1/DDX46 axis regulates BCR expression.

ABSTRACT: Epitranscriptomic modifications, particularly N6-methyladenosine (m6A), have emerged as critical regulators of RNA stability, localization, and translation, shaping immune responses and tumor progression. In B-cell biology, m6A modifications influence germinal center formation and antigen-driven differentiation, underscoring their importance in immune regulation. Among m6A regulators, ALKBH5 (RNA demethylase) is pivotal in removing methylation marks and modulating gene expression in diverse cellular contexts. Despite advancements in understanding m6A dynamics, the mechanistic interplay between m6A demethylation and B-cell receptor (BCR) signaling pathways still needs to be explored. This study reveals a novel regulatory axis involving ALKBH5, treRNA1 (Translation Regulatory Long Non-Coding
