Metabolite Identification
Common NameN2,N2-Dimethylguanosine
DescriptionN2,N2-Dimethylguanosine is an urinary nucleoside, a primary degradation product of tRNA. The mean levels of urinary N2,N2-Dimethylguanosine in the patients with colorectal cancer are significantly higher than those in patients with intestinal villous adenoma or the healthy adults (PMID 15991285 ).
