TNF-αG-308A polymorphism is associated with insulin resistance: a meta-analysis

H. G. Wang, Yang, J., Han, H., Xu, F., Bian, Y., Zhang, H., and Wang, J. L., TNF-αG-308A polymorphism is associated with insulin resistance: a meta-analysis, vol. 14, pp. 563-573, 2015.

Tumor necrosis factor-α (TNF-α) promoter polymorphisms has been reported to be associated with obesity and insulin resistance and gained widespread attention. However, results obtained so far are quite conf‍‍licting. We therefore performed a meta-analysis to address this issue, basing on 17 studies from electronic databases (MEDLINE and EMBASE).

Association of the FABP2 Ala54Thr polymorphism with type 2 diabetes, obesity, and metabolic syndrome: a population-based case-control study and a systematic meta-analysis

Y. Liu, Wu, G., Han, L., Zhao, K., Qu, Y., Xu, A., and Huang, Q., Association of the FABP2 Ala54Thr polymorphism with type 2 diabetes, obesity, and metabolic syndrome: a population-based case-control study and a systematic meta-analysis, vol. 14, pp. 1155-1168, 2015.

Previous studies have reported associations between the functional FABP2 Ala54Thr (rs1799883) polymorphism and type 2 diabetes mellitus (T2DM), obesity, and metabolic syndrome in different populations with conflicting results. We investigated the association between the FABP2 Ala54Thr polymorphism and T2DM (235 cases, 431 controls), obesity (377 cases, 431 controls), and metabolic syndrome (315 cases, 323 controls) by logistic regression analysis in a Chinese study cohort recruited from Yichang, Hubei Province.

Associations between genetic variants and the severity of metabolic syndrome in subjects with type 2 diabetes

Y. L. Chen, Pei, D., Hung, Y. J., Lee, C. H., Hsiao, F. C., Wu, C. Z., Lin, J. D., Hsu, C. H., Chang, J. B., and Hsieh, C. H., Associations between genetic variants and the severity of metabolic syndrome in subjects with type 2 diabetes, vol. 14, pp. 2518-2526, 2015.

Metabolic syndrome (MetS) includes obesity, dyslipidemia, elevated blood pressure, and dysglycemia. Subjects with type 2 diabetes (T2D) exhibit features of MetS. The etiology of MetS is complex, involving both environmental and genetic factors. In this study, we examined the role of specific candidate genetic variants on the severity of MetS in T2D subjects. A total of 240 T2D subjects aged 35-64 years were recruited. Waist circumstance, plasma triglycerides, high-density lipoprotein cholesterol, fasting plasma glucose, and blood pressure were measured to define MetS.

Prader-Willi-like phenotypes: a systematic review of their chromosomal abnormalities

C. F. Rocha and Paiva, C. L. A., Prader-Willi-like phenotypes: a systematic review of their chromosomal abnormalities, vol. 13. pp. 2290-2298, 2014.

Prader-Willi syndrome (PWS) is caused by the lack of expression of genes located on paternal chromosome 15q11-q13. This lack of gene expression may be due to a deletion in this chromosomal segment, to maternal uniparental disomy of chromosome 15, or to a defect in the imprinting center on 15q11-q13. PWS is characterized by hypotonia during the neonatal stage and in childhood, accompanied by a delay in neuropsychomotor development. Overeating, obesity, and mental deficiency arise later on.

Relationship between serum creatinine and obesity in children in Xinjiang, China

X. - M. Li, Ma, Y. - T., Xie, X., Yang, Y. - N., Li, X. M., and Zheng, Y. - Y., Relationship between serum creatinine and obesity in children in Xinjiang, China, vol. 13, pp. 2409-2416, 2014.

This study was designed to analyze the relationship between serum creatinine and body mass index in children in Xinjiang, China. We used a stratified sampling method to select 5222 children aged 6-17 years in 3 areas in Xinjiang and then measured serum creatinine with an enzymatic method. Our analysis showed that the mean serum creatinine of the various age groups differed, and the reference value increased gradually with age.

Genetic associations of the INSIG2 rs7566605 polymorphism with obesity-related metabolic traits in Malaysian Malays

Y. D. Apalasamy, Moy, F. M., Rampal, S., Bulgiba, A., and Mohamed, Z., Genetic associations of the INSIG2 rs7566605 polymorphism with obesity-related metabolic traits in Malaysian Malays, vol. 13, pp. 4904-4910, 2014.

A genome-wide association study showed that the tagging single nucleotide polymorphism (SNP) rs7566605 in the insulin-induced gene 2 (INSIG2) was associated with obesity. Attempts to replicate this result in different populations have produced inconsistent findings. We aimed to study the association between the rs7566605 SNP with obesity and other metabolic parameters in Malaysian Malays. Anthropometric and obesity-related metabolic parameters and DNA samples were collected. We genotyped the rs7566605 polymorphism in 672 subjects using real-time polymerase chain reaction.

Association of serum adipose triglyceride lipase levels with obesity and diabetes

L. Yang, Chen, S. J., Yuan, G. Y., Zhou, L. B., Wang, D., Wang, X. Z., and Chen, J. J., Association of serum adipose triglyceride lipase levels with obesity and diabetes, vol. 13, pp. 6746-6751, 2014.

The aim of this study was to detect the serum adipose triglyceride lipase (ATGL) levels in obesity and newly diagnosed type 2 diabetes patients, and to explore the association between ATGL with glucose and lipid metabolism. We enrolled 66 patients with type 2 diabetes and 48 patients with normal glucose regulation, who were divided into an overweight or obese subgroup and a normal weight subgroup according to body mass index (BMI) ≥ 25 kg/m2. The enzyme-linked immunosorbent assay was used to detect fasting blood glucose, blood lipids, fasting insulin, and ATGL levels.

Roles of beta2-adrenergic receptor gene polymorphisms in a Turkish population with obstructive sleep apnea syndrome or obesity

İ. Gök, Çelebi, İ., Hüseyinoğlu, N., and Özic, C., Roles of beta2-adrenergic receptor gene polymorphisms in a Turkish population with obstructive sleep apnea syndrome or obesity, vol. 13, pp. 8511-8518, 2014.

We determined the distribution of the Arg16Gly and Gln27Glu polymorphisms of the beta-2 adrenergic receptor gene (ADRB2) in patients with obstructive sleep apnea syndrome as well as a control group in Northeastern Turkey. A total of 52 patients diagnosed with obstructive sleep apnea in a sleep laboratory and 78 control subjects were examined. Peripheral blood samples were taken from patients diagnosed with obstructive sleep apnea by polysomnography. DNA was extracted from blood samples and amplified using polymerase chain reaction.

Prevalence and risk factors of overweight and obesity among individuals over 40 years old in Luzhou city

J. Zeng, Wan, Q., Bai, X., Li, X. Z., Liu, F., Li, C., Liu, X. Y., and Wang, Y., Prevalence and risk factors of overweight and obesity among individuals over 40 years old in Luzhou city, vol. 13, pp. 9262-9270, 2014.

In this study, a survey was conducted through questionnaire distribution and physical examinations were performed in 10,150 residents that were over 40 years old in Luzhou city. Respondents were selected by the multi-stage sampling method. The mean body mass index (BMI) of the sample population was 23.9 ± 3.3 kg/m2. Among men, BMI showed a negative relationship with increasing age (P

A family-based association study identified CYP17 as a candidate gene for obesity susceptibility in Caucasians

H. Yan, Guo, Y., Yang, T. - L., Zhao, L. - J., and Deng, H. - W., A family-based association study identified CYP17 as a candidate gene for obesity susceptibility in Caucasians, vol. 11, pp. 1967-1974, 2012.

The cytochrome P450c17α gene (CYP17) encodes a key biosynthesis enzyme of estrogen, which is critical in regulating adipogenesis and adipocyte development in humans. We therefore hypothesized that CYP17 is a candidate gene for predicting obesity.
