Abstract Genetic modifications in the adiponectin receptor 2 (AdipoR2) gene can affect phenotypes associated with insulin resistance and diabetes. The purpose of this study was to evaluate the possible role of genetic modifications in the AdipoR2 gene, to determine the frequency of genotypes and polymorphism alleles of this gene at rs11061971 (+ 219 A > T), and to investigate its correlation with type 2 diabetes (T2D) and its related metabolic profile. In this case-control study, the single-nucleotide polymorphism (SNP) of interest in 116 T2D patients and 102 controls was evaluated using RFLP PCR and FOK 1 enzyme. Fasting blood sugar, cholesterol, triglyceride, insulin, HDL-C, LDL-C and HbA1c were also measured and their correlation with the studied genetic modifications was assessed. The collected data were analyzed using Chi-square test and Hardy-Weinberg equation. There was a significant association in AT and TT genotypes in rs11061971 (+ 219 A > T) with T2D. However, no significant difference was observed in the frequency of alleles between the case and control groups. In addition, in LDL-C and total cholesterol in the control group, there was a significant difference between AA and TT genotypes as well as with AA and AT genotypes. However, no correlation was found between the other serum studied parameters and the genotype of individuals in the rs1106197171 polymorphism. The role of rs11061971 (+ 219 A > T) polymorphism in T2D incidence seems to be strong. This study showed that AT and TT genotypes versus AA genotype increase the risk of diabetes.

ABSTRACTMembrane lipid composition influences vital processes in all types of cells. The mechanisms by which cells maintain membrane lipid homeostasis while obtaining most of their constituent fatty acids from a varied diet remain largely unknown. In an attempt to discover such mechanisms, we performed an unbiased forward genetic screen in Caenorhabditis elegans and conclude that the adiponectin receptor 2 (AdipoR2) pathway is essential to prevent saturated fat-mediated cellular toxicity. Transcriptomics, lipidomics and membrane property analyses in human HEK293 cells and primary human endothelial cells further support our conclusion that the essential function of AdipoR2 is to respond to membrane rigidification by promoting fatty acid desaturation. Our results demonstrate that AdipoR2-dependent regulation of membrane homeostasis is a fundamental mechanism conserved from nematodes to mammals that prevents saturated fat-mediated lipotoxicity.ONE SENTENCE SUMMARYThe AdipoR2 protein insures membrane homeostasis in response to dietary saturated fatty acids that promote membrane rigidification.

Investigated prevalence of alleles and genotypes G(-2548)A (rs7799039) gene leptin and G(276)T (rs1501299) of the adiponectin and A(+219)T (rs11061971) adiponectin receptor 2 in patients with psoriasis with abdominal obesity. The frequency of the allele A of the promoter region of the G(-2548) A polypeptide leptin gene in 99/226 (43,8%) patients with a body mass index ≥30 kg / m2 was found to be higher than in69/228 (30,3% ) patients with a body mass index

The kidney is an important organ in the maintenance of body homeostasis. Dietary compounds, reactive metabolites, obesity, and metabolic syndrome (MetS) can affect renal filtration and whole body homeostasis, increasing the risk of chronic kidney disease (CKD) development. Gamma oryzanol (γOz) is a compound with antioxidant and anti-inflammatory activity that has shown a positive action in the treatment of obesity and metabolic diseases. Aim. To evaluate the effect of γOz to recover renal function in obese animals by high sugar-fat diet by modulation of adiponectin receptor 2/PPAR-α axis Methods. Male Wistar rats were initially randomly divided into 2 experimental groups: control and high sugar-fat diet (HSF) for 20 weeks. When proteinuria was detected, HSF animals were allocated to receive γOz or maintain HSF for more than 10 weeks. The following were analyzed: nutritional and biochemical parameters, systolic blood pressure, and renal function. In the kidney, the following were evaluated: inflammation, oxidative stress, and protein expression by Western blot. Results. After 10 weeks of γOz treatment, γOz was effective to improve inflammation, increase antioxidant enzyme activities, increase the protein expression of adiponectin receptor 2 and PPAR-α, and recover renal function. Conclusion. These results permit us to confirm that γOz is able to modulate PPAR-α expression, inflammation, and oxidative stress pathways improving obesity-induced renal disease.
