“…16 PARP activity is positively correlated with speciesspecific life span in mammalian species. 17,18,19 A (gt)n repeat polymorphism lies in exon 1. 20 The known six alleles, designated according to size (85 bp-99 bp size range), show bimodal frequency distribution, with peaks at 85 bp and 93 bp alleles.…”

“…There are two forms of ADPRT/PARP-1 activity: (1) the constitutive level, associated with normal cellular processes; and (2) the induced level in response to DNA damage [Pero et al, 1985]. Several previous studies reported a positive correlation between its enzyme activity and the species' life span [Pero et al, 1985;Grube and Burkle, 1992;Burkle et al, 1994]. The mRNA levels and enzyme activities were higher in younger than in older subjects [Muiras et al, 1998;Burkle, 2000;Ly et al, 2000], suggesting that poly(ADPribosyl)ation plays a role in aging.…”

“…Cellular ADPRT/PARP-1 may slow the rate of genomic instability resulting from constant exposure to endogenous and exogenous DNA-damaging agents, thereby affecting aging [Burkle et al, 1994;2001;Kapahi et al, 1999]. There are two forms of ADPRT/PARP-1 activity: (1) the constitutive level, associated with normal cellular processes; and (2) the induced level in response to DNA damage [Pero et al, 1985].…”

“…More recently PARP gene expression was studied and demonstrated to be associated to genetic instability in human breast cancer (Bieche et al, 1996). The activity of PARP was shown to positively correlate with species-specific life span of mammals (Burkle et al, 1994). It is known that telomeres shorten with age and this may influence genetic instability (Murnane, 1996), although the potential role of PARP activity in these phenomena remains to be elucidated.…”

“…Among these are nucleosomal core histones, histone HI, HMG proteins, topoisomerases I and II and PARP itself (Braz and Lechner, 1986; Althaus, 1987). The catalytic activity of PARP is strongly dependent on the presence of DNA strand breaks, which represent the sites for the enzyme recognition (Gradwohl et al, 1990;Ikejima et al, 1990;Molinete et al, 1993;Burkle et al, 1994;Panzeter et al, 1994). The stimulation of PARP by reactive oxygen species has been demonstrated Heller et al, 1995;Crist6vao and Rueff, 1996).…”
