The 341C/T polymorphism in the GSTP1 gene and lung cancer risk: a meta-analysis

F. Yan, Wang, R., Geng, L., Yan, F., Wang, R., and Geng, L., The 341C/T polymorphism in the GSTP1 gene and lung cancer risk: a meta-analysis, vol. 15, p. -, 2016.

Numerous studies have evaluated the association between the 341C/T polymorphism in glutathione S-transferase P1 (GSTP1) and lung cancer risk. However, there are conflicting results from previous studies. To derive a more precise estimation of the association, we conducted this meta-analysis. A comprehensive search was conducted to identify the eligible studies examining the GSTP1 341C/T polymorphism and lung cancer risk. We used odds ratios (ORs) with 95% confidence intervals (CIs) to assess the strength of the association.

Lack of association between the ESR1 rs9340799 polymorphism and age at menarche: a meta-analysis

H. Y. Wu, Xing, X. K., Wang, K. J., Zhang, L., Wu, H. Y., Xing, X. K., Wang, K. J., and Zhang, L., Lack of association between the ESR1 rs9340799 polymorphism and age at menarche: a meta-analysis, vol. 15, p. -, 2016.

It has been reported that the estrogen receptor alpha (ESR1) rs9340799 polymorphism is associated with age at menarche (AAM). However, recent investigations have generated inconsistent results. This study aimed to establish a more precise estimation of the association between this polymorphism and AAM. A meta-analysis was conducted based on an in silico literature search using PubMed. Six studies presenting continuous data, including ESR1 rs9340799 genotype frequencies, were selected.

Meta-analysis of IL-6 -174G/C polymorphism and psoriasis risk

G. Nie, Xie, C. L., Cao, Y. J., Xu, M. M., Shi, X., Zou, A. L., Qi, J. H., Nie, G., Xie, C. L., Cao, Y. J., Xu, M. M., Shi, X., Zou, A. L., and Qi, J. H., Meta-analysis of IL-6 -174G/C polymorphism and psoriasis risk, vol. 15, p. -, 2016.

Previous studies examining the association between interleukin-6 (IL-6) -174G/C polymorphism and psoriasis risk have produced inconsistent results. The aim of this study was to offer a comprehensive review of the association between IL-6 -174G/C polymorphism and psoriasis risk through a meta-analysis. Literature search of PubMed and Embase databases was conducted to identify all eligible studies published before October 29, 2015. Four case-control studies involving 651 psoriasis cases and 552 controls were included in this meta-analysis.

Association between monoamine oxidase B A644G polymorphism and Parkinson’s disease risk: a meta-analysis in the Chinese population

J. J. Liu, Wang, W., Meng, M., Liang, C. S., Zhang, J. W., Liu, J. J., Wang, W., Meng, M., Liang, C. S., and Zhang, J. W., Association between monoamine oxidase B A644G polymorphism and Parkinson’s disease risk: a meta-analysis in the Chinese population, vol. 15, p. -, 2016.

Although various individual studies have evaluated the correlation between monoamine oxidase B (MAOB), polymorphism, and Parkinson’s disease (PD), the results remain inconclusive. Therefore, we performed a meta-analysis in the Chinese population to provide comprehensive data on the association between the MAOB polymorphism and PD. Eligible studies were identified via databases such as PubMed, Springer Link, Ovid, Chinese Wanfang Data Knowledge Service Platform, Chinese National Knowledge Infrastructure, and Chinese Biology Medicine, throughout November 2015.
