CLDN10 single nucleotide polymorphism rs1325774 alters the risk of breast cancer in south chinese women.

ABSTRACT: Breast cancer is one of the most widespread malignancies in females, and the incidence rate has been increasing in recent years in the world. Genetic factors play an important role in the occurrence of breast cancer. Our study aimed to investigate the relationship between single nucleotide polymorphisms (SNPs) of claudin 10 (CLDN10) (rs1325774, rs7333503, rs3751334) and breast cancer and the clinical characteristics of patients.A total of 104 patients with breast cancer and 118 healthy controls were recruited in our study between 2013 and 2015. The SNPscan system was used for genotyping. Demographic information, health status, anthropometric parameters and clinical data were considered in analysis. Statistical analysis of the data was carried out using the Student t test, the Chi-square test (X2) or Fisher exact test and unconditional logistic regression analysis. The Gene Expression Profiling Interactive Analyses application (GEPIA) was used to analysis the expression of CLDN10 in breast cancer tissues and normal samples.The polymorphism of rs1325774 was significantly associated with an increased risk of breast cancer (T/G vs T/T: OR?=?2.073, 95% CI?=?1.095-3.927, P?=?.025). After adjusting for age, the association remained statically significant (T/G vs T/T: OR?=?2.067, 95% CI?=?1.070-3.867, P?=?.026). Furthermore, harbouring G allele in rs1325774 position was significantly associated with increased risk of breast cancer (OR?=?1.993, 95% CI?=?1.107-3.589, P?=?.022). However, no significant association among rs7333503, rs3751334, and breast cancer. The expression level of CLDN10 was reduced in breast cancer tissues compared with normal breast tissues according to the analysis of The Cancer Genome Atlas (TCGA) data through GEPIA.Our results suggest that the polymorphism of rs1325774 associate with increase the breast cancer risk. No significant relationship between rs1325774 polymorphism and clinical as well as pathological characteristics in patients.

Project description:BackgroundGallstones are abnormal masses caused by impaired metabolism of cholesterol, bilirubin, or bile salts in the gallbladder or biliary tract. ATP-binding cassette subfamily G member 8 (ABCG8) is a protein that regulates cholesterol efflux from the liver. Genome-wide association studies (GWAS) and meta-analyses of GWAS revealed the ABCG8 rs11887534 variant as the most common genetic determinant of gallstones in humans. These findings have not been extensively replicated in Taiwanese. Therefore, we appraised the relationship between gallstones and rs11887534 in a relatively large Taiwanese sample.MethodsWe retrieved data collected through questionnaires, physical and biochemical tests from the Taiwan Biobank Bank (TWB). The study participants comprised 7388 men and 13,880 women who voluntarily enrolled in the Taiwan Biobank project between 2008 and 2019. Gallstones were self-reported.ResultsThe overall sample size was 21,268 comprising 938 gallstone patients and 20,330 non-gallstone individuals. Among the participants, 20,640 had the GG and 628 had the GC + CC genotype. At p-value < 0.05, the baseline genotypes and gallstone status between men and women were not significantly different. The risk of gallstones was higher in participants having the GC + CC compared to the GG genotype: odds ratio (OR); 95% confidence interval (CI) = 1.698; 1.240-2.325), but was lower in men compared to women (OR = 0.763; 95% CI = 0.638-0.913). Compared to men with the rs11887534 GG genotype, women with the GG and GC + CC genotypes had a higher risk of gallstone (OR; 95% CI = 1.304; 1.087-1.565 for GG and 2.291; 1.514-3.467 for GC + CC). The positive association between GC + CC and gallstones was retained after we restricted the analysis to the female participants (OR; 95% CI = 1.789 = 1.208-2.648). Hormone use was associated with an elevated risk of gallstones (OR; 95% CI = 1.359; 1.107-1.668). Relative to GG and no hormone use, we found a significantly high risk among hormone users with the GC + CC genotype (OR; 95% CI = 3.596; 1.495-8.650).ConclusionsThe rs11887534 GC + CC genotype was independently associated with a higher risk of gallstones. This risk was much higher among women, especially those who used hormones for various gynecological purposes.
