N2,N2-dimethylguanosine

view
  • Name: N2,N2-dimethylguanosine
  • Description: N2,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. This compound is found in higher levels in the blood of old healthy people as compared to young healthy people making it a biomarker in the study of ageing. Correlations between this metabolite and others found either in too higer or lower concentrations suggest that some functions are compromised in elderly healthy people.
