Ribosomal RNA 2'O-methylation as a novel layer of inter-tumour heterogeneity in breast cancer.

Recent epitranscriptomics studies unravelled that ribosomal RNA (rRNA) 2'O-methylation is an additional layer of gene expression regulation highlighting the ribosome as a novel actor of translation control. However, this major finding lies on evidences coming mainly, if not exclusively, from cellular models. Using the innovative next-generation RiboMeth-seq technology, we established the first rRNA 2'O-methylation landscape in 195 primary human breast tumours.

2'-O-Methylation of Ribosomal RNA: Towards an Epitranscriptomic Control of Translation?

Ribosomal RNA (rRNA) undergoes post-transcriptional modification of over 200 nucleotides, predominantly 2'-O-methylation (2'-O-Me). 2'-O-Methylation protects RNA from hydrolysis and modifies RNA strand flexibility but does not contribute to Watson-Crick base pairing. The contribution of 2'-O-Me to the translational capacity of ribosomes has been established.
