1976), a progressive increase in sensitivity to digestion by the e n z y m e w a s found with age of the mice. This indicates that mice a c c u m u l a t e single-strand regions in their heart D N A as they age. Mori and G o t o (1982), h o w e v e r , could not repeat this Si e n d o n u c l e a s e result. T h e basis for this discrepancy is unclear. 48 I Accumulation of DNA Damage in Somatic Cells Zahn et al. (1987) studied age-correlated D N A damage in human muscle tissue. D N A damage was determined as D N A alterations that give rise to complete molecular b r e a k s during the treatment of purified D N A solutions with single-strand-specific nucleases.

T h e a u t h o r s concluded that a large proportion of the D N A in small n e u r o n s of the cerebellum undergoes no metabolic t u r n o v e r during the h u m a n life span. Other studies, reviewed by Slatkin et al. (1985), also have shown that in vivo most m o u s e brain neuronal D N A is metabolically stable. 1 3 1 2 1 3 1 2 1 3 I 2 Altogether, low D N A repair capacity w a s shown in all 10 studies on neuronal tissue (for s u m m a r y , see Table III).
