Reading between the bases: technological advances in RNA modification detection

|
By Isaia Barbieri, Maxim Bouvet
| Frontiers
Abstract Despite the rapid expansion of epitranscriptomics, accurately detecting and mapping RNA modifications remains a major technical challenge that limits our understanding of their functional and therapeutic relevance. More than 170 chemical RNA modifications have been identified, collectively shaping the epitranscriptome through dynamic regulation of RNA processing, stability, localization, and translation.

Abstract Mitochondria play a central role in metastatic spread and cancer progression, with the IκBα/NF-κB signaling axis acting as a key regulator of both processes. We suggest that a stable fraction of IκBα localizes to mitochondria, where it escapes proteasomal degradation and acquires oncogenic functions independent of its canonical role in NF-κB inhibition.

| Nature Verified
Abstract METTL9 is an enzyme catalysing N1-methylation of histidine residues (1MH) within eukaryotic proteins. Given its high expression in vertebrate nervous system and its potential association with neurodevelopmental delay, we dissected Mettl9 role during neural development.
