Background: The objective of this study was to investigate whether the genetic polymorphism rs12665607 of ESR1, rs10995190 of ZNF365, rs3817198 of LSP1 and rs17001868 of SGSM3/MKL1 are associated with the development of breast cancer (BC) in the Chinese women. Methods: The 4 SNPs were genotyped for 453 female BC patients and 750 controls. The differences of genotype and allele distributions between patients and controls were evaluated using the Chi-square test. The comparison of SGSM3 expression in the tumor and the adjacent normal breast tissues was carried out by the Student’s t test. One-way ANOVA test was used to analyze the relationship between genotypes of rs17001868 and the tissue expression of SGSM3. Results: Patients were found to have significantly higher allele T of rs12665607 and allele C of rs17001868 than that of the controls (35.2 % vs. 29.6 %, p = 0.004 for rs12665607; 23.1 % vs. 19.1 %, p = 0.02 for rs17001868). The OR values were 1.29 for rs12665607 and 1.27 for rs17001868, respectively. The mean expression level of SGSM3 was significantly lower in BC tumors than in the adjacent normal tissues (0.0082 ± 0.0038 vs. 0.0134 ± 0.0078; p < 0.001). Patients with genotype CC were found to have a remarkably lower SGSM3 expression in the tumors than those with genotype AA (p = 0.007). Conclusions: ESR1 gene and the SGSM3 gene are associated with the risk of BC in Chinese population. Besides, rs17001868 may be a putative functional variant that can affect the expression of SGSM3 in patients with BC. With the OR ranging from 1.27 to 1.29, variants of these 2 genes can only explain limited variance of BC. Further investigations into the functional role of the susceptible genes would be helpful to clarify the etiology of BC. © 2016 The Japanese Breast Cancer Society

The D19S884 marker at the fibrillin 3 gene has been analysed as a candidate location for polycystic ovary syndrome (PCOS) mainly in Caucasian descendants. A case-control study was performed with 272 PCOS women and 271 controls to test the hypothesis that variants in the D19S884 marker increase susceptibility to PCOS in Chinese women and a meta-analysis was undertaken to clarify whether there is an allele consistently contributing to the susceptibility. The association analysis showed that PCOS women were significantly different from controls in the distribution of D19S884 allele frequencies. Instead of the well-known A8 allele, the most common allele in Chinese population was proved to be A7, and the allele frequencies of A7 were statistically different between cases and controls (P = 0.037). The meta-analysis of A8 and A7 only identified A8 as a significant allelic association at the D19S884 marker in all combined samples (A8: OR 1.391, 95% CI 1.169-1.654; A7: OR 1.154, 95% CI 0.894-1.490). In conclusion, the association study showed a potential association of the D19S884 marker with PCOS in Chinese Han women and the meta-analysis identified that A8 may increase susceptibility to PCOS. Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age, and it affects an estimated 15% of women worldwide based on the Rotterdam criteria. Many studies in Caucasian descendants suggested that variants of the D19S884 marker at the fibrillin 3 gene are associated with the risk of this syndrome. Here we performed a case-control study with 272 PCOS women and 271 controls to investigate whether variants in the D19S884 marker increase susceptibility to PCOS in Chinese women. We also carried out a meta-analysis of some relevant studies to find a more reliable result. Our association analysis showed that PCOS women were significantly different from controls in the distribution of D19S884 allele frequencies, and instead of the well-known A8 (the letter 'A' represents 'allele'), the most common allele in Chinese population was proved to be A7, whose allele frequencies were statistically different between cases and controls. The meta-analysis of A8 and A7 only identified A8 as a significant allelic association at the D19S884 marker in all combined samples. In conclusion, our association study showed a potential association of the D19S884 marker with PCOS in Chinese Han women and the meta-analysis identified that A8 may increase susceptibility to PCOS. © 2012, Reproductive Healthcare Ltd.

Objective: To evaluate the safety profile of nicergoline compared with placebo and other active agents from published randomised controlled trials. Design: Systematic review and meta-analysis of nicergoline compared with placebo and other active agents across various indications. Data sources: MEDLINE, Medline-in-process, Cochrane, EMBASE, EMBASE alerts, Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Database of Systematic Reviews (CDSR) and Cochrane Methodology Register (CMR) for all the randomised controlled trials, open-label or blinded, in adults treated with nicergoline. Studies published until August 2013 were included. Review method: 29 studies were included for data extraction. The studies included in this review were majorly from European countries and mostly in cerebrovascular disease (n=15) and dementia (n=8). Results: The treatment withdrawals were comparatively lower in the nicergoline group as compared with the placebo group (RR=0.92; 95% CI 0.7 to 1.21) and other active comparators (RR=0.45; 95% CI 0.10 to 1.95), but the difference was non-significant. Incidence of any adverse events (AEs) was slightly higher (RR=1.05; 95% CI 0.93 to 1.2) while incidence of serious AEs was lower (RR=0.85; 95% CI 0.50 to 1.45) in the nicergoline compared with placebo group. Frequency of anxiety was significantly lower in nicergoline as compared with placebo (p=0.01). Other AEs including diarrhoea, gastric upset, dizziness and drowsiness were less frequent in the nicergoline group when compared with placebo/active drugs, but the difference was non-significant. Frequency of hypotension and hot flushes was slightly higher in the nicergoline group but the difference was non-significant. None of the studies reported any incidence of fibrosis or ergotism with nicergoline treatment. Conclusions: Nicergoline is an ergot derivative, but its safety profile is better than other ergot derivatives like ergotamine and ergotoxine. This systematic review and meta-analysis suggests that nicergoline has a good safety profile. None of the studies included in this systematic review reported any incidence of fibrosis or ergotism with nicergoline.

Alzheimer Disease and Associated Disorders | Year: 2014
PURPOSE:: Recently, a large genome-wide association study has revealed that polymorphism of alleles and genotypes in rs3,764,650 within ABCA7 gene is associated with Alzheimer disease in whites. We conducted a case-control study to investigate whether these susceptible genetic variants are risk factors for sporadic Alzheimer disease (SAD) in Chinese Han population. DESIGN AND METHODS:: A total of 633 participants consisting of 350 SAD and 283 nondemented elderly controls matched for sex and age were recruited and genetic variants in ABCA7 (rs3,764,650) were genotyped using DNA sequencing. RESULTS:: On the basis of allele and genotype frequencies in both groups, we found a significant association (P=0.004) between ABCA7 genotypes and SAD in Chinese Han population, and the results were influenced by age and ApoEε4 status. ApoEε4-carrier and aging are linked to enhancing ABCA7 risk-associated SAD. However, the prevalence of the minor allele G in rs3,764,650 within ABCA7 showed no significant difference between the 2 groups in this study. CONCLUSIONS:: ABCA7 (rs3,764,650) was associated with SAD in the Chinese population, with both ApoEε4-carrier and aging being factors enhancing its risk.

Evidence is accumulating that cyclooxygenase-2 (COX-2) may play an important role in prostate cancer (PCa). Recently, gene polymorphisms in COX-2 have been implicated to alter the risk of PCa and overexpression of COX-2 may be associated with clinical and prognostic significance in PCa. However, the results of these studies are inconclusive or controversial. To derive a more precise estimation of the relationships, we performed an updated meta-analysis. A comprehensive search was conducted to examine all the eligible studies of COX-2 polymorphism and expression in PCa. We used odds ratios (ORs) to assess the strength of the association and the 95 % confidence intervals (CIs) give a sense of the precision of the estimate. Overall, no significant associations between COX-2 polymorphism and PCa risk were found. However, high expression of COX-2 was significantly higher in T3-T4 stages of PCa than in T1-T2 stages of PCa (OR = 2.33, 95 %CI: 1.54-3.53, P < 0.0001). COX-2 might play an important role in the progress of PCa, overexpression of COX-2 correlates with T3-T4 stages of PCa. COX-2 might be a potential therapy target for PCa and work as a prognostic factor for PCa patients.
