Özet

The findings of the studies on poly(ADP-ribose) polymerase-1 (PARP-1) have suggested that the enzyme inactivation provides significant protection against systemic or tissue inflammation in animal models. It has also shown that the single-nucleotide polymorphism (Val762Ala) of the PARP-1 causes about 40% decrease of enzyme activity. The aim of this study was to analyze the association of the PARP-1 Val762Ala polymorphism in Turkish patients with rheumatoid arthritis. A total of 128 RA patients and 165 normal controls from the same geographic region were studied and polymerase chain reaction (PCR)-based restriction analysis was used to identify Val762Ala polymorphism of the PARP-1. Association analyses were performed using chi (2) tests. Our results indicated that the distribution of the PARP-1 genotypes and alleles did not differ significantly among subjects with or without RA (P > 0.05). The results of the study indicate that, for our Turkish sample, the V762A polymorphism of the PARP-1 may not be involved in susceptibility to RA, implying that the polymorphism may not function as a candidate gene marker for screening RA patients.
