DNA repair is quite conserved and important for living organisms as stated above. Markers of DNA damage - observe in age-associated disease Obvious evident -- ppl who has defective in DNA repair -- show features of premature or accelerated aging Defect in different pw --aging features in different tissues; Cockayne syndrome, ataxia-telangiectasia -- premature neurological aging Werner syndrome, Hutchinson-Gilford progeria -- cardiovascular aging >50 DNA repair disorders described with various degrees of overlapping phenotypes with aging -- > suggest different types of DNA damage -- > different pathologie
