The Role of N6‐Methyladenosine Modification in Health and Disease
MedComm, Volume 7, Issue 6, June 2026.N6‐methyladenosine (m6A) is the most prevalent internal RNA modification in eukaryotes, acting as a pivotal epitranscriptomic regulator of RNA metabolism. This modification plays a dual role: it maintains physiological homeostasis under normal conditions but drives disease progression when dysregulated.
