5-Hydroxymethyl-2-deoxycytidine

5-Hydroxymethyl-2'-deoxycytidine is an oxidized derivative of 5-methyl-2'-deoxycytidine (5-mdC) in DNA, causing DNA damage reactions, chromosomal aberrations, replication fork damage, and loss of cell viability.5-Hydroxymethyl-2'-deoxycytidine is an oxidized derivative of 5-methyl-2'-deoxycytidine in DNA. Hydroxymethyl-2'-deoxycytidine replication fork instability is associated with the presence of poly (ADP-ribose) polymerase 1 (PARP1) on chromatin.
