RAD51 plays a key role in homologous recombination repair of double-stranded DNA breaks which may cause chromosomal breaks
and genomic instability. We performed a meta-analysis of 9 epidemiological studies involving 13,241 cases and 13,203 controls
that examined the association between RAD51 135G>C polymorphism and breast cancer. No significant association of RAD51 135G>C
polymorphism with breast cancer was found in overall and European populations. However, after the studies which did not fulfill
Hardy–Weinberg equilibrium were excluded, we observed an overall significant increased breast cancer risk (for the recessive
model CC vs. GG/CG: OR = 1.35, 95% CI = 1.05–1.74, P
heterogeneity = 0.06). In summary, our meta-analysis suggested the RAD51 135G>C polymorphism may contribute to breast cancer susceptibility. 相似文献

Published data on the association between TGFB1 L10P polymorphism and breast cancer risk are inconclusive. In order to derive
a more precise estimation of the relationship, a meta-analysis was performed. Crude ORs with 95% CIs were used to assess the
strength of association between them. A total of 30 studies including 20,401 cases and 27,416 controls were involved in this
meta-analysis. Overall, significantly elevated breast cancer risk was associated with TGFB1 10P allele when all studies were
pooled into the meta-analysis (LP vs. LL: OR = 1.046, 95% CI = 1.003–1.090; dominant model: OR = 1.052, 95% CI = 1.012–1.095).
In the subgroup analysis by ethnicity, statistically significantly elevated risk was found in Caucasians (dominant model:
OR = 1.045, 95% CI = 1.001–1.091). When stratified by study design, statistically significantly elevated risk was found based
on population-based studies (dominant model: OR = 1.076, 95% CI = 1.019–1.136). In conclusion, this meta-analysis suggests
that the TGFB1 10P allele may be a low-penetrant risk factor for developing breast cancer. However, large sample and representative
population-based studies with homogeneous breast cancer patients and well-matched controls are warranted to confirm this finding. 相似文献

Published data on the association between STK15 F31I polymorphism and breast cancer risk are inconclusive. In order to derive
a more precise estimation of the relationship, a meta-analysis was performed. Medline, PubMed, Embase, Web of Science, and
Chinese Biomedicine Database were searched. Crude ORs with 95% CIs were used to assess the strength of association between
the STK15 F31I polymorphism and breast cancer risk. The pooled ORs were performed for codominant model (FI vs. FF; II vs.
FF), dominant model (FI + II vs. FF), and recessive model (II vs. FI + FF), respectively. A total of 10 studies including
10,537 cases and 14,477 controls were involved in this meta-analysis. Overall, significantly elevated breast cancer risk was
associated with II variant genotype in homozygote comparison and recessive genetic model when all studies were pooled into
the meta-analysis (for II vs. FF: OR = 1.23, 95% CI = 1.10–1.37; for recessive model: OR = 1.21, 95% CI = 1.05–1.40). In the
subgroup analysis by ethnicity, significantly increased risks were found for II allele carriers among Caucasians (for II vs.
FF: OR = 1.24, 95% CI = 1.08–1.43; for recessive model: OR = 1.21, 95% CI = 1.00–1.45); significantly increased risks were
also found among Asians for II versus FF (OR = 1.21; 95% CI = 1.01–1.45). In conclusion, this meta-analysis suggests that
the STK15 31II allele is a low-penetrant risk factor for developing breast cancer. 相似文献

Published data on the association between present/null polymorphism of glutathione S-transferase M1 (GSTM1) and breast cancer risk are inconclusive. To derive a more precise estimation of the relationship, a meta-analysis was performed. Medline, PubMed, Embase, and Web of Science were searched. Crude ORs with 95% CIs were used to assess the strength of association between the GSTM1 present/null polymorphism and breast cancer risk. The pooled ORs were performed for null versus present genotype. A total of 59 studies including 20,993 cases and 25,288 controls were involved in this meta-analysis. Overall, significantly elevated breast cancer risk was associated with null genotype when all studies were pooled into the meta-analysis (OR = 1.10, 95% CI = 1.04–1.16). In the subgroup analysis by ethnicity, significantly increased risks were found for Caucasians (OR = 1.05, 95% CI = 1.00–1.10) and Asians (OR = 1.21, 95% CI = 1.08–1.35). When stratified by population-based studies or hospital-based studies, statistically significantly elevated risks were found among population-based studies (OR = 1.11, 95% CI = 1.03–1.20). In the subgroup analysis by menopausal status, statistically significantly increased risks were found among postmenopausal women (OR = 1.15, 95% CI = 1.04–1.28). In conclusion, this meta-analysis suggests that the GSTM1 null genotype is a low-penetrant risk factor for developing breast cancer. 相似文献

The RAD51 gene is essential for the repair of damaged DNA related to tumor development. Although a number of genetic studies have attempted to link the 135G/C polymorphism of RAD51 gene to the risk of cancer, the results were inconclusive. The present study aimed at investigating the pooled association using the more comprehensive meta-analysis. The PubMed, EBSCO, and BIOSIS databases were searched to identify eligible studies which were published in English before March 2014. Data were extracted using standardized methods. The association was assessed by odds ratio (OR) with 95 % confidence interval (CI). Begg’s test was used to measure publication bias. Sensitivity analyses were also performed to assess the stability of the results. A total of 45 eligible studies with 28,956 patients and 28,372 controls were included in this meta-analysis. Overall, significant association was detected between 135G/C polymorphism and increased cancer risk (C allele vs. G allele: OR 1.23, 95 % CI 1.18–1.28; CC vs. GG: OR 2.41, 95 % CI 2.12–2.74; CC vs. CG: OR 3.86, 95 % CI 3.41–4.37; recessive model: OR 3.57, 95 % CI 3.19–4.00). In further stratified analysis, significantly elevated cancer risk was observed among Caucasians but not Asians. Subgroup analysis by different cancers also showed their significant associations in breast cancer, hematologic malignances, ovarian cancer, colorectal cancer and endometrial cancer, but not in head and neck cancer. Our results indicated that the RAD51 135G/C polymorphism was a candidate for susceptibility of cancer. The effect of the variants on the expression levels and the possible functional role of the variants in different cancers should be addressed in further studies. 相似文献

Published data on the association between MTHFR C677T polymorphism and breast cancer risk are inconclusive. To derive a more
precise estimation of the relationship, a meta-analysis was performed. Medline, PubMed, Embase, and Web of Science were searched.
Crude ORs with 95% CIs were used to assess the strength of association between the MTHFR C677T polymorphism and breast cancer
risk. The pooled ORs were performed with co-dominant model (CT vs. CC, TT vs. CC), dominant model (CT + TT vs. CC), and recessive
model (TT vs. CC + CT), respectively. A total of 37 studies including 15,260 cases and 20,411 controls were involved in this
meta-analysis. Overall, significantly elevated breast cancer risk was associated with TT variant genotype in homozygote comparison
and dominant genetic model when all studies were pooled into the meta-analysis (TT vs. CC: OR = 1.11, 95% CI = 1.01–1.23;
dominant model: OR = 1.04, 95% CI = 1.00–1.09). In the subgroup analysis by ethnicity, significantly increased risks were
found for TT allele carriers among Asians (TT vs. CC: OR = 1.18, 95% CI = 1.04–1.35; recessive model: OR = 1.15, 95% CI = 1.03–1.29).
When stratified by study design, statistically significantly elevated risk was found in hospital-based studies (TT vs. CC:
OR = 1.18, 95% CI = 1.02–1.38; recessive model: OR = 1.17, 95% CI = 1.05–1.29). In the subgroup analysis by menopausal status,
statistically significantly increased risk was found among postmenopausal women (CT vs. CC: OR = 1.12, 95% CI = 1.02–1.23;
dominant model: OR = 1.11, 95% CI = 1.01–1.22). In conclusion, this meta-analysis suggests that the MTHFR T allele is a low-penetrant
risk factor for developing breast cancer. 相似文献

Germline mutations in many of the genes that are involved in homologous recombination (HR)-mediated DNA double-strand break repair (DSBR) are associated with various human genetic disorders and cancer. RAD51 and RAD51 paralogs are important for HR and in the maintenance of genome stability. Despite the identification of five RAD51 paralogs over a decade ago, the molecular mechanism(s) by which RAD51 paralogs regulate HR and genome maintenance remains obscure. In addition to the known roles of RAD51C in early and late stages of HR, it also contributes to activation of the checkpoint kinase CHK2. One recent study identifies biallelic mutation in RAD51C leading to Fanconi anemia-like disorder. Whereas a second study reports monoallelic mutation in RAD51C associated with increased risk of breast and ovarian cancer. These reports show RAD51C is a cancer susceptibility gene. In this review, we focus on describing the functions of RAD51C in HR, DNA damage signaling and as a tumor suppressor with an emphasis on the new roles of RAD51C unveiled by these reports. 相似文献

BRCA2 N372H polymorphism and breast cancer susceptibility: a meta-analysis involving 44,903 subjects
Li-Xin Qiu Lei Yao Kai Xue Jian Zhang Chen Mao Bo Chen Ping Zhan Hui Yuan Xi-Chun Hu 《Breast cancer research and treatment》2010,123(2):487-490
Published data on the association between BRCA2 N372H polymorphism and breast cancer risk are inconclusive. To derive a more
precise estimation of the relationship, a meta-analysis was performed. Crude ORs with 95% CIs were used to assess the strength
of association between them. A total of 22 studies including 22,515 cases and 22,388 controls were involved in this meta-analysis.
Overall, no significant associations were found between BRCA2 N372H polymorphism and breast cancer risk when all studies pooled
into the meta-analysis (NH versus NN: OR = 1.01, 95% CI = 0.97–1.05; HH versus NN: OR = 1.05, 95% CI = 0.97–1.13; dominant
model: OR = 1.01, 95% CI = 0.98–1.05; and recessive model: OR = 1.05, 95% CI = 0.98–1.13). In the subgroup analysis by ethnicity,
still no significant associations were found for Caucasians, Asians, or Africans. When stratified by study design, statistically
significantly elevated risk was found for 372H allele based on population-based studies (HH versus NN: OR = 1.11, 95% CI = 1.01–1.21;
dominant model: OR = 1.05, 95% CI = 1.00–1.10; recessive model: OR = 1.09, 95% CI = 1.00–1.18). In conclusion, this meta-analysis
suggests that the BRCA2 372H allele may be a low-penetrant risk factor for developing breast cancer. However, large sample
and representative population-based studies with homogeneous breast cancer patients and well matched controls are warranted
to confirm this finding. 相似文献

The A2756G polymorphism in the methionine synthase (MTR) gene has been implicated in breast cancer risk. However, the published
findings are inconsistent. We therefore performed a meta-analysis to investigate this relationship. Eleven published case–control
studies, including 8,438 breast cancer cases and 10,515 controls were identified. Odds ratios (ORs) and 95% confidence intervals
(CIs) were used to assess the strength of the association. Overall, no significant associations between the MTR A2756G polymorphism
and breast cancer risk were found for GG versus AA (OR = 0.98, 95% CI: 0.84–1.15), AG versus AA (OR = 0.95, 95% CI: 0.89–1.01),
GG/AG versus AA (OR = 0.95, 95% CI = 0.89–1.01), and GG versus AG/AA (OR = 1.00, 95% CI: 0.86–1.17). However, in the stratified
analysis, significantly decreased breast cancer risks were found among Europeans (AG versus AA, OR = 0.90, 95% CI = 0.83–0.98;
GG/AG versus AA, OR = 0.90, 95% CI = 0.82–0.97) and studies with population-based controls (AG versus AA, OR = 0.93, 95% CI = 0.86–1.00;
GG/AG versus AA, OR = 0.93, 95% CI = 0.86–1.00). When stratifying by the menopausal status, no significant result was observed
in all genetic models. Taken together, the results suggest that the MTR A2756G polymorphism may contribute to susceptibility
to breast cancer among Europeans. 相似文献

Study results on the association between RAD51 gene -135G/C polymorphism and risk of myelodysplastic syndrome (MDS) or acute leukemia are inconsistent. A meta-analysis was conducted to identify the association. A systematic search was performed in PubMed, Embase, CNKI, VIP, Wanfang databases to collect all relevant studies until January 2013. Meta-analysis was carried out using fixed/random model by Review Manager 5.1 and STATA10.0. A total of 10 eligible studies with 2,656 patients and 3,725 controls were included in meta-analysis. Significant association was detected between -135G/C polymorphism and increased MDS risk (CC?+?GC vs. GG: OR?=?1.46, 95 % CI?=?1.11–1.92; CC vs. GC?+?GG: OR?=?2.45, 95 % CI?=?1.23–4.89), while no association was observed for acute leukemia. Subgroup analysis by subtypes of acute leukemia and ethnicity showed no significant results either. Our meta-analysis indicated that the -135G/C polymorphism might be associated with increased susceptibility of MDS. However, lack of evidence supported association of this polymorphism with acute leukemia. Additional well-designed studies with larger samples are required to verify our results. 相似文献

Cyclin D1 (CCND1) plays an essential role in tumor development and progression through regulating the cell transition from G1 to the proliferative S phase. The CCND1 G870A polymorphism has been associated with an increased susceptibility to squamous cell carcinoma of the head and neck, bladder, prostate, and gastric cardiac cancers. There are a number of studies that explored the relationship between CCND1 G870A polymorphism and breast cancer risk, with inconsistent conclusions. In order to better define the predictive value of CCND1 G870A polymorphism in breast cancer, we searched PubMed and EBSCO for relevant publications. A total of 13 studies were indentified, which included 11,235 cases and 12,763 controls. We calculated the summary odds ratios and the corresponding 95% confidence interval. Our meta-analysis showed that carriers of AA genotype have a significantly higher risk in developing breast cancer compared with that of GG genotype (OR = 1.08, 95% CI = 1.01-1.17, p > = 0.03) in overall population. Furthermore, in subgroup analysis, CCND1 G870A polymorphism was associated with a marginally increased risk of breast cancer for Chinese compared to Caucasian populations with an OR = 1.14, 95% CI = 1.00-1.20, p-trend = 0.06 for AA + GA versus GG, if the controls were hospital-based population with an OR = 1.21, 95% CI = 0.99-1.47, p = 0.06 for AA versus GG and if the distributions of genotypes in control groups were consistent with the Hardy-Weinberg equilibrium (HWE) with an OR = 1.08, 95% CI = 1.00-1.15, p = 0.04 for AA versus GA + GG. Our meta-analysis represents the largest study to date indicating that the G870A polymorphism in CCND1 confers an increased risk for breast cancer. Further studies are warranted to explore the preventive measures to detect and manage the breast cancers attributable to the G870A polymorphism. 相似文献

Mutations in RAD51 gene are believed to be associated with elevated breast cancer risk. However, several case–control studies focusing on the
association between RAD51 135G>C and breast cancer risk failed to achieve consensus. To clarify the effect of RAD51 135G>C polymorphism on breast cancer, a meta-analysis was performed. By searching PubMed and EMBASE, a total of 14 case–control
studies, containing 12,183 cases and 10,183 controls, were included. The strength of association between RAD51 135G>C polymorphism and breast cancer risk was assessed by odds ratio (OR) with the corresponding 95% confidence interval
(95% CI). When all the eligible studies were pooled into the meta-analysis, an elevated cancer risk was revealed in additive
model (OR, 1.34; 95% CI, 1.01–1.78; P = 0.044) and recessive model (OR, 1.37; 95% CI, 1.03–1.82; P = 0.032). In subgroup analyses by ethnicity, BRCA1/2 mutation status, and family history, a significant association was found only among BRCA2 mutation carriers (additive model: OR, 4.92; 95% CI, 1.11–21.83; P = 0.036; recessive model: OR, 4.88; 95% CI, 1.10–21.67; P = 0.037). Sensitivity analysis did not perturb the results. In conclusion, this meta-analysis suggests that RAD51 variant 135C homozygote is associated with elevated breast cancer risk among BRCA2 mutation carriers. 相似文献

Published data on the association between cytochrome P-450 1A2 (CYP1A2)-164 A/C polymorphism and breast cancer risk are inconclusive.
To derive a more precise estimation of the relationship, a meta-analysis was performed. Medline, PubMed, Embase, and Web of
Science were searched. Crude ORs with 95% CIs were used to assess the strength of association between CYP1A2-164 A/C polymorphism
and breast cancer risk. The pooled ORs were performed for co-dominant model (AC versus AA, CC versus AA), dominant model (CC + AC
versus AA), and recessive model (CC versus AA + AC), respectively. A total of 9 studies including 7,580 cases and 10,020 controls
were involved in this meta-analysis. Overall, no significantly elevated breast cancer risk was found in all genetic models
when all studies were pooled into the meta-analysis (AC versus AA: OR = 1.02, 95% CI = 0.92–1.13; CC versus AA: OR = 1.17,
95% CI = 0.83–1.64; dominant model: OR = 1.07, 95% CI = 0.93–1.23; and recessive model: OR = 1.13, 95% CI = 0.82–1.55). In
the subgroup analysis by ethnicity or source of controls, there was still no significant association detected in all genetic
models. In conclusion, upto date, there is still no enough evidence to indicate the association of CYP1A2-164 A/C polymorphism
and breast cancer development. 相似文献

Transforming growth factor β1 (TGF-β1) is a cytokine, playing an important role in controlling cell proliferation and differentiation
involved in breast cancer. It was reported the 29T/C polymorphism in TGF-β1 has been implicated in breast cancer risk. However,
studies on the association between this polymorphism and breast cancer remain conflicting. To derive a more precise estimation
of the relationship, a meta-analysis of 10,341 cases and 15,655 controls from fifty published case-control studies was performed.
Our analysis suggested that 29T/C has no association with a trend of breast cancer risk when using both dominant [odds ratio
(OR) = 1.01, 95% confidence intervals (CI) 0.96–1.07] and recessive models (OR = 0.98, 95% CI 0.89–1.08) to analyze the data.
In ethnic subgroups analysis, 29T/C also did not appear to be risk factors for breast cancer. However, larger scale primary
studies are required to further evaluate the interaction of TGF-β1 29T/C polymorphism and breast cancer risk in specific populations. 相似文献

Many studies were published to assess the association between FASLG T844C polymorphism and susceptibility to breast cancer, but the data were controversial. A meta-analysis was performed to assess the association comprehensively. We performed a comprehensive search in PubMed, Embase, and Web of Science to find eligible studies. Six studies with a total of 6,784 participants were finally included into the meta-analysis. There were a total of 3,382 cases with breast cancer and 3,402 controls in those six studies. Odds ratio (OR) with 95 % confidence interval (95 %CI) was used to evaluate the association. Overall, there was an obvious association between FASLG T844C polymorphism and breast cancer under all four contrast models (for C versus T: OR?=?1.26, 95 %CI 1.05–1.50, P OR?=?0.011; for CC versus TT: OR?=?1.42, 95 %CI 1.11–1.81, P OR?=?0.005; for CC versus TT/TC: OR?=?1.41, 95 %CI 1.06–1.88, P OR?=?0.019; for CC/TC versus TT: OR?=?1.16, 95 %CI 1.01–1.33, P OR?=?0.038). In the subgroup analysis by ethnicity, there was an obvious association between FASLG T844C polymorphism and breast cancer in Asians, but there was no obvious association in Caucasians. The meta-analysis suggests that there is an association between FASLG T844C polymorphism and susceptibility to breast cancer, especially in Asians. 相似文献

Breast cancer is one of the most common malignant tumors worldwide. To date, many articles have evaluated the association
between Cytochrome P450c17 (CYP17) T-34C polymorphism and breast cancer risk. However, the results remain inconclusive. In
order to derive a more precise estimation of the association, a meta-analysis was performed in this study. By searching Medline,
ISI Web of Knowledge, Cochrane, ScienceDirect, EBSCO, CNKI, and SinoMed databases, 43 studies including 26,008 cases and 32,806
controls were collected for CYP17 T-34C polymorphism. Crude ORs with 95% CIs were used to assess the strength of association
between CYP17 T-34C polymorphism and breast cancer risk. The pooled ORs were performed for codominant model, dominant model,
and recessive model, respectively. Overall, no significant associations between CYP17 T-34C polymorphism and breast cancer
susceptibility were found for TT versus CC (OR = 0.96; 95% CI: 0.89–1.05), TC versus CC (OR = 0.97; 95% CI: 0.89–1.06), TT + TC
versus CC (OR = 0.97; 95% CI: 0.89–1.05) and TT versus TC + CC (OR = 0.98; 95% CI: 0.93–1.03). In the stratified analysis
by ethnicity, menopausal status, and sources of controls, significant associations were still not detected in all genetic
models. In conclusion, this meta-analysis strongly suggests that CYP17 T-34C polymorphism is not associated with breast cancer
risk. 相似文献

Published data on the association between insulin-like growth factor binding protein 3 (IGFBP3) A-202C polymorphism and breast
cancer risk are inconclusive. To derive a more precise estimation of the relationship, a meta-analysis was performed. Crude
ORs with 95% CIs were used to assess the strength of association between them. A total of 27 studies including 33,557 cases
and 45,254 controls were involved in this meta-analysis. Overall, significantly elevated breast cancer risk was associated
with IGFBP3 C allele when all studies were pooled into the meta-analysis (CC vs. AA: OR = 1.06, 95% CI = 1.02–1.11; dominant
model: OR = 1.04, 95% CI = 1.00–1.07). In the subgroup analysis by ethnicity, significantly increased risk was found for Caucasians
(AC vs. AA: OR = 1.04, 95% CI = 1.00–1.08; CC vs. AA: OR = 1.05, 95% CI = 1.01–1.10; dominant model: OR = 1.04, 95% CI = 1.00–1.08)
and Asians (CC vs. AA: OR = 1.35, 95% CI = 1.02–1.78; recessive model: OR = 1.38, 95% CI = 1.05–1.82). When stratified by
study design, statistically significantly elevated risk was found among population-based studies (CC vs. AA: OR = 1.06, 95%
CI = 1.01–1.11; dominant model: OR = 1.03, 95% CI = 1.00–1.07). In the subgroup analysis by menopausal status, no statistically
significantly increased risk was found among premenopausal or postmenopausal women. In conclusion, this meta-analysis suggests
that the IGFBP3 C allele is a low-penetrant risk factor for developing breast cancer. 相似文献

Breast cancer is a complex disease with both genetic and environmental factors involved in its etiology. An important role of polymorphisms in genes involved in DNA repair has been reported related to breast cancer risk. We conducted a case–control study in order to investigate the association of RAD51 135G>C and TP53 Arg72Pro polymorphisms with breast cancer in Serbian women.48 BRCA negative women with breast cancer and family history of breast/ovarian cancer (hereditary group), 107 women with breast cancer but without family history of the disease (sporadic group) and 114 healthy women without a history of the disease (control group) were included. Restriction fragment length polymorphism was used for genotyping. Genotype and allelic frequencies, the odds ratio (OR) and the 95 % confidence interval (CI) were calculated as an estimate of relative risk. The Hardy–Weinberg equilibrium was tested using χ2 test. Significance was considered for p < 0.05. RAD51 135G>C showed statistically significant association of CC genotype and increased breast cancer risk (OR 10.28, 95 % CI 1.12–94.5) in hereditary group of patients compared to the control group. Regarding the TP53 Arg72Pro, we showed statistical significance for ProPro + ProArg comparing to ArgArg (OR 2.34, 95 %, CI 1.17–4.70) in hereditary compared to sporadic group. RAD51 135G>C contributes to hereditary breast cancer in Serbian population, with CC genotype as a risk factor. We also found that carriers of Pro allele of TP53 codon 72 is related to hereditary cancer comparing to sporadic one, which indicates it as a potential risk factor for hereditary form of disease. 相似文献
