04/01/2002 - "There was also the suggestion that vegetable intake may not be protective against lung cancer among subjects with the Cys/Cys genotype. "
02/01/2014 - "When all studies were pooled, a significantly increased overall lung cancer risk was found (Cys/Cys vs. Ser/Ser: OR = 1.24, 95 % CI = 1.05-1.47, P = 0.013; recessive model: OR = 1.22, 95 % CI = 1.05-1.41, P = 0.008, and Cys vs. Ser: OR = 1.11, 95 % CI = 1.02-1.21, P = 0.022), and further stratification analysis showed that the association was stronger in Asians, never smokers, and more-cigarette takers. "
07/01/2008 - "In stratified analyses by control source, compared with the Ser/Ser genotype, lung cancer risk associated with the hOGG1 Cys/Cys genotype was significantly increased in population-based studies (OR, 1.32; 95% CI, 1.04-1.67) but not in hospital-based studies (OR, 1.18; 95% CI, 0.98-1.42); in stratified analyses by the smoking status, however, the increased risk was observed only among nonsmokers in a dominant model (OR, 1.32; 95% CI, 1.04-1.67). "
01/01/2012 - "The results showed that individuals carrying the Cys/Cys genotype did not have significantly increased risk for lung cancer (OR = 1.15, 95% CI = 0.98-1.36) when compared with the Ser/Ser genotype; similarly, no significant association was found in recessive, dominant or heterozygous co-dominant model (Ser/Cys vs. Cys/Cys). "
01/01/2011 - "In the subgroup analyses by ethnicity, histological type, smoking status, significant association with lung cancer risk in Asians was found either in the dominant (crude OR, 1.19; 95% CI, 1.07-1.33 for Cys/Cys+Ser/Cys versus Ser/Ser) or recessive (crude OR, 1.21; 95% CI, 1.08-1.35 for Cys/Cys versus Ser/Cys+Ser/Ser) model. "

03/19/2020 - "Based on genetic characteristics of individuals included in this study, results suggest that MTHFR CT and OGG1 Cys/Cys genotypes have a protective effect that may have an influence on breast cancer risk in a representative Northern Sardinian population."
01/01/2018 - "This study suggested that the carrier of Ser326Cys polymorphism of hOGG1, Cys/Cys vs Ser/Ser, are at higher risk for breast cancer, independent of other hormonal and environmental risk factors."
03/19/2020 - "A nominally significant association with breast cancer risk was observed for MTHFR C677T polymorphism heterozygous genotype in the codominant model (OR: 0.57, 95% CI: 0.32-1.00, p = 0.049) and for Cys/Cys genotype of the OGG1 Ser326Cys polymorphism in the recessive model (OR: 0.23, 95% CI: 0.05-1.11, p = 0.0465). "
09/01/2018 - "The variant allele of BRCA1 Cys39Gly increased breast cancer risk (Gly/Cys versus Cys/Cys, OR: 12.2, 95%CI: 1.53; 98.1), and carriers of the variant allele of CYP17A1 -34T>C had reduced risk (CT+CC versus TT, OR: 0.44, 95%CI: 0.21; 0.93). "
06/03/2014 - "However, in subgroup analyses by ethnicity and menopausal status, statistical significant increased breast cancer risk was found in Asian populations (Cys/Cys vs. Ser/Ser: OR=1.157, 95% CI 1.013-1.321, P=0.011; Cys/Cys vs. Ser/Cys+Ser/Ser: OR=1.113, 95% CI 1.009-1.227, P=0.014) and postmenopausal patients (Cys/Cys vs. Ser/Cys+Ser/Ser: OR=1.162, 95% CI 1.003-1.346, P=0.024). "

01/01/2012 - "As to histological types, we found the Cys/Cys was associated with adenocarcinoma risk (Ser/Ser vs. Cys/Cys: OR = 1.32, 95% CI = 1.12-1.56; Ser/Cys vs. Cys/Cys: OR = 1.19, 95% CI = 1.04-1.37, and recessive model OR = 1.23, 95% CI = 1.08-1.40). "
01/01/2012 - "Despite some limitations, this meta-analysis established solid statistical evidence for an association between the OGG1 Cys/Cys genotype and lung cancer risk, particularly for studies with large sample size and adenocarcinoma, but this association warrants additional validation in larger and well designed studies."
12/01/2009 - "By histology-based analysis, the Cys/Cys genotype showed a significantly positive association with small-cell carcinoma (OR=2.40, 95% CI=1.32-4.49) and marginally significant association with adenocarcinoma (OR=1.32, 95% CI=0.98-1.77). "
04/20/2005 - "The associations between the OGG1 Cys/Cys genotype and adenocarcinoma risk and between XRCC1 Arg194Trp polymorphism and lung cancer risk among heavy smokers remained robust given prior probabilities of 25% (FPRP = 0.238) and 10% (FPRP = 0.276), respectively. "
04/20/2005 - "The overall odds ratio for lung cancer among those with the OGG1 Cys/Cys genotype compared with those with the OGG1 Ser/Ser genotype was 1.34 (95% CI = 0.95 to 1.88); the association was most prominent for adenocarcinoma risk (OR = 1.66, 95% CI = 1.04 to 2.66). "

01/01/2006 - "Subjects carrying the Cys/Cys genotype had significantly lower insulin sensitivity levels, assessed by homeostasis model assessment-insulin resistance (HOMA-IR), compared with the Ser/Ser and Ser/Cys genotypes (P < 0.001 and P < 0.001, respectively). "
01/01/2006 - "The present study indicates that the hOGG1 gene Cys/Cys variant is associated with a significant decrease in insulin sensitivity in subjects with normal glucose tolerance."

06/14/2015 - "This study showed that Cys-Cys (CC) type chemokines such as CCL2, CCL8, CCL1, CCL24, CCL11, CCL7, CCL12 and CCL5 were elevated significantly at the late phase of infection. "
