Abstract Background The role of N1‐methyladenosine (m1A) in cancer is poorly understood. Here we explored the function of RNA methyltransferase TRNA methyltransferase 61A (TRMT61A) in colorectal cancer (CRC) and its potential as a therapeutic target. Methods RNA m1A levels were assessed through liquid chromatography‐mass spectrometry.
