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.

A. N. Zhu, Yang, X. X., Sun, M. Y., Zhang, Z. X., and Li, M., Associations between INSR and MTOR polymorphisms in type 2 diabetes mellitus and diabetic nephropathy in a Northeast Chinese Han population, vol. 14, pp. 1808-1818, 2015.

We explored the associations of INSR and mTOR, 2 key genes in the insulin signaling pathway, and the susceptibility to type 2 diabetes mellitus and diabetic nephropathy. Three single-nucleotide polymorphisms (SNPs) (rs1799817, rs1051690, and rs2059806) in INSR and 3 SNPs (rs7211818, rs7212142, and rs9674559) in mTOR were genotyped using the Sequenom MassARRAY iPLEX platform in 89 type 2 diabetes patients without diabetic nephropathy, 134 type 2 diabetes patients with diabetic nephropathy, and 120 healthy control subjects.

J. K. Feng, Lu, Y. F., Li, J., Qi, Y. H., Yi, M. L., and Ma, D. Y., Upregulation of salivary α2 macroglobulin in patients with type 2 diabetes mellitus, vol. 14, pp. 2268-2274, 2015.

We investigated the expression of salivary α2-macroglobulin (α2-MG) in patients with type 2 diabetes mellitus (T2DM) to investigate its value for predicting damage to the salivary glands. A total of 116 patients with T2DM and 60 patients with impaired fasting glucose (IFG) were included in this study. Sixty health volunteers were enrolled as a control group. Unstimulated saliva was collected at 8 a.m. prior to breakfast. Expression of α2-MG was determined using an enzyme-linked immunosorbent assay.

Role of APN and TNF-α in type 2 diabetes mellitus complicated by nonalcoholic fatty liver disease

X. Lin, Zhang, Z., Chen, J. M., Xu, Y. Y., Ye, H. R., Cui, J., Fang, Y., Jin, Y., Zhu, D. R., and Yuan, L., Role of APN and TNF-α in type 2 diabetes mellitus complicated by nonalcoholic fatty liver disease, vol. 14, pp. 2940-2946, 2015.

Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease caused by non-excessive alcohol consumption and is the most common cause of elevated levels of serum liver enzymes. We examined changes in adiponectin (APN) and tumor necrosis factor-α (TNF-α) in type 2 diabetes mellitus (T2DM) complicated by NAFLD and their relationships with insulin resistance (IR). Forty-two T2DM, 39 NAFLD, and 45 T2DM complicated with NAFLD (complicated group) patients were enrolled in this study.

Promotive effect of comprehensive management on achieving blood glucose control in senile type 2 diabetics

S. - T. Yan, Li, C. - X., Li, C. - L., Li, J., Shao, Y. - H., Liu, Y., Zhong, W. - W., Fang, F. - S., Sun, B. - R., and Tian, H., Promotive effect of comprehensive management on achieving blood glucose control in senile type 2 diabetics, vol. 14, pp. 3062-3070, 2015.

The aim of this study was to evaluate the control of blood glucose and glycosylated hemoglobin A1c (HbA1c) and its influencing factors, in elderly type 2 diabetic mellitus (T2DM) patients undergoing comprehensive management. After years of comprehensive prevention of and control measures for diabetes, elderly T2DM patients who were receiving long-term health care were comprehensively evaluated through an annual physical examination. In addition to routine health examination, the patients were required to undergo HbA1c measurement.

Correlation between polymorphism of platelet alloantigen genes HPA-1-5 and type 2 diabetes complication by carotid atherosclerosis in a Chinese population

Y. H. Zhang, Xu, S. F., Zheng, J., Hong, H. S., and Fan, L. M., Correlation between polymorphism of platelet alloantigen genes HPA-1-5 and type 2 diabetes complication by carotid atherosclerosis in a Chinese population, vol. 14, pp. 4607-4615, 2015.

We investigated the association between the polymorphism of human platelet alloantigen genes HPA-1-HPA-5 and the complication of type 2 diabetes mellitus (T2DM) by carotid atherosclerosis (CA) among Han people in Guiyang District, China. Ninety-nine T2DM patients were selected from the Affiliated Hospital of Guiyang Medical College and divided into a CA(+) group and a CA(-) group. A control group comprised 100 healthy people from the medical examination center of the same hospital.

This study aims to investigate the association of peroxisome proliferator-activated receptor (PPAR) delta -87T/C polymorphism with several sugar metabolism indices and tumor necrosis factor α (TNF α) level. The body mass index (BMI), waist size, and levels of fasting plasma glucose, serum lipid, fasting insulin, TNFα, and PPAR delta -87T/C of 286 patients with type 2 diabetes mellitus (T2DM) and 158 subjects with normal fasting glucose (NFG) were measured in a Dalian population.

We investigated the association between vitamin D receptor (VDR) and susceptibility to type 2 diabetes mellitus (T2DM). Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis was conducted to examine single nucleotide polymorphisms (SNPs) of the rs1544410 (BsmI, G>A), rs757343 (Tru9I, G>A), rs731236 (TaqI, T>C), and rs739837 (BglI, G>T) loci of the VDR gene in 334 healthy individuals (Hui 115, Han 219) and 355 T2DM patients (Hui 154, Han 201) living in the Ningxia Hui Autonomous Region of China.

Association between FTO, MC4R, SLC30A8, and KCNQ1 gene variants and type 2 diabetes in Saudi population

M. D. Bazzi, Nasr, F. A., Alanazi, M. S., Alamri, A., Turjoman, A. A., Moustafa, A. S., Alfadda, A. A., Pathan, A. A. K., and Parine, N. R., Association between FTO, MC4R, SLC30A8, and KCNQ1 gene variants and type 2 diabetes in Saudi population, vol. 13, pp. 10194-10203, 2014.

Recent genome wide association studies identified many loci in several genes that have been consistently associated with type 2 diabetes mellitus in various ethnic populations. Among the genes that were most strongly associated with diabetes were fat mass- and obesity-associated, melanocortin 4 receptor, solute carrier family 30 member 8 (SLC30A8), and a member of the potassium voltage-gated channels.

Role of mitochondrial DNA variants and copy number in diabetic atherogenesis

M. C. Chien, Huang, W. T., Wang, P. W., Liou, C. W., Lin, T. K., Hsieh, C. J., and Weng, S. W., Role of mitochondrial DNA variants and copy number in diabetic atherogenesis, vol. 11, pp. 3339-3348, 2012.

Hyperglycemia-induced reactive oxygen species production can cause diabetes and its complications, including atherosclerosis. The role of mitochondrial DNA variants and mitochondrial copy number in the pathogenesis of diabetic atherogenesis is not well understood. We examined 36 diabetic patients who had undergone amputation for diabetic foot and seven non-diabetic patients who had undergone amputation after traumatic injury. Mitochondrial DNA was extracted and used for sequencing. Single nucleotide polymorphisms (SNPs) relative to the Cambridge reference sequence were analyzed.
