Quantification of modified nucleotides and nucleosides by isotope dilution mass spectrometry
Mass Spectrometry Reviews, Volume 43, Issue 5, Page 998-1018, September/October 2024.Abstract Epigenetic modifications are closely related to certain disorders of the organism, including the development of tumors. One of the main epigenetic modifications is the methylation of DNA cytosines, 5‐methyl‐2′‐deoxycycytidine. Furthermore, 5‐mdC can be oxidized to form three new modifications, 5‐(hydroxymethyl)‐2′‐deoxycytidine, 5‐formyl‐2 ...
