While Val762Ala polymorphism was associated with reduced susceptibility to DR, the Arg399Gln polymorphism contributed an elevated to risk for DR in South-Indian T2DM individuals.
Our findings support the view that PARP-1 Val762Ala polymorphism may contribute to an increased risk of lung cancer in the Chinese population, especially for adenocarcinoma.
The present meta-analysis provides evidence that the PARP-1 Val762Ala may be involved in cancer development at least in some ethnic groups (Asian) or some specific cancer types (gastric, cervical, and lung cancers, and glioma).
eNOS 894G > T and PARP-1 Val762Ala polymorphisms appeared to associate significantly with DN, with the former contributing to an enhanced risk and the latter to a reduced susceptibility to DN in South Indian T2DM individuals.
In conclusion, this meta-analysis suggests that the PARP-1 rs1136410: T > C polymorphism is a susceptibility factor for GI cancers, but the variant allele of MGMT rs12917: C > T polymorphism appears to be a protective factor for colorectal cancer.
In conclusion, APE1 (Asp148Glu), PARP1 (Ala762Val), and XRCC1 (Arg399Gln, Arg194Trp) were associated with the susceptibility to CRC, but were not associated with the prognosis of CRC.
The 242T and 762Ala alleles were significantly more frequent in T2DM subjects without CAD than those with CAD, </span>thereby associating them with a significant protective effect against development of CAD [p=0.002 (C242T); 0.02 (Val762Ala)].
The association between higher red meat intake (>3 servings per week) and CRC was modified by the PARP Val762Ala single-nucleotide polymorphisms (SNP; case-only interaction P = 0.026).
The present study implies that genetic variants of PARP-1 may contribute to breast cancerogenesis and that PARP-1 htSNP c.852T>C (Ala284Ala) may influence hormonal therapy of breast cancer.

We investigated associations between the risk of lung cancer in residents of the coal-mining region and polymorphisms in the genes APEX1 (rs1130409), hOGG1 (rs1052133), XRCC1 (rs25489, rs25487), XRCC2 (rs3218536), XRCC3 (rs861539), ADPRT/PARP1 (rs1136410), XPD/ERCC2 (rs13181), XPG/ERCC5 (rs17655), XPC (rs2228001), ATM (rs1801516), and NBS1 (rs1805794).
In rs1136410 (Val762Ala) heterozygous mutant genotype (CT) was observed notably lower (OR: 0.44., 95% CI: 0.33-0.57., p<0.0001) in brain tumor patients compared to controls and ~2 fold increased frequency of homozygous mutant genotype (CC) was observed in brain tumor patients versus controls (OR: 1.51., 95%CI: 1.16-1.96, p = 0.001).

Major allele homozygote (CC) of rs1136410 and combined genotype (TT+TC) of rs180414 showed a significant association with thyroid cancer risk (OR = 1.30; 95% CI 0.99-1.77; P = 0.05) and (OR = 0.43; 95% CI = 0.27-0.67; P = 0.03).

Taken together, our data suggest that SNP rs1136410 may confer protection against CAD through modulation of PARP activities and gene-environment interactions in a Chinese Han population.
