Abstract
Purpose Metabolic syndrome (MetS) is characterized by abdominal obesity, hyperglycaemia, dyslipidaemia and hypertension. FTO gene has been implicated in the pathogenesis of obesity, but the available scientific data concerning their relationship to antipsychotic drug-induced obesity and metabolic syndrome is still incomplete and inconsistent, which indicates that continuing the investigation of this gene’s role is necessary. Patients and Methods In the present study, 517 patients with schizophrenia underwent antipsychotic drug treatment, and two groups were identified: patients with MetS and without MetS. Genotyping of 6 SNPs in the FTO gene was performed, and the results analyzed using R-programme. Results We performed a statistical analysis to identify possible associations of the frequencies of genotypes and alleles of the studied polymorphisms with the presence of metabolic syndrome in schizophrenia patients, with the presence of abdominal obesity, and with an increased body mass index. The rs7185735 polymorphism did not meet the Hardy-Weinberg criterion and was excluded. After correcting for differences in age, gender and duration of illnesses, none of the variants was shown to be related to metabolic syndrome or abdominal obesity, but rs9939609, rs1421085, rs3751812 and rs8050136 were associated with body mass index. Conclusion The present study provides additional support for these SNP’s roles as a pharmacogenetic biomarker that may become useful in the framework of the personalized medicine approach.

Abstract
Type 2 diabetes mellitus (T2DM) is a non-autoimmune, complex, heterogeneous and polygenic metabolic disease condition characterized by persistent elevated blood glucose levels (hyperglycemia). India as said to be the diabetic capital of the world is likely to experience the largest increase in T2DM and a greater number of diabetic individuals in the world by the year 2030. Identification of specific genetic variations in a particular ethnic group has a critical role in understanding the risk of developing T2DM in a much efficient way in future. These genetic variations include numerous types of polymorphisms among which single nucleotide polymorphisms (SNPs) is the most frequent. SNPs are basically located within the regulatory elements of several gene sequences. There are scores of genes interacting with various environmental factors affecting various pathways and sometimes even the whole signalling network that cause diseases like T2DM. This review discusses the biomarkers for early risk prediction of T2DM. Such predictions could be used in order to understand the pathogenesis of T2DM and to better diagnostics, treatment, and eventually prevention.

Caruso V, Bahari H, Morris MJ. The beneficial effects of early short-term exercise in the offspring of obese mothers are accompanied by alterations in the hypothalamic gene expression of appetite regulators and FTO (fat mass and obesity associated) gene.

Abstract
Maternal overnutrition is implicated in the development of adult metabolic disease, and has been shown to alter the expression of genes involved in energy homeostasis. In the present study, we aimed to test whether a short period of voluntary exercise, followed by a sedentary period, would regulate hypothalamic markers involved in appetite. Adult female Sprague-Dawley rats were fed either normal chow or high-fat diet (HFD) ad lib. for 5 weeks, mated and continued on their assigned diet during gestation/lactation. At weaning males, were separated into chow or HFD groups; half were exercised (running wheels), whereas the remainder were sedentary. At week 10, wheels were removed and rats remained sedentary for 5 weeks, prior to tissue collection. Maternal obesity increased offspring adiposity at 15 weeks and this was exacerbated by postnatal HFD (P < 0.05). Body weight and fat mass were reduced in offspring of obese mothers if they exercised, and this was maintained even after 5 weeks without exercise. At 15 weeks, fasting plasma insulin, leptin and triglyceride concentrations were significantly reduced by exercise in offspring of lean and obese mothers consuming chow, with little benefit in those consuming HFD. Hypothalamic mRNA expression of pro-opiomelanocortin was increased by exercise but only in offspring of lean mothers. Exercise reduced hypothalamic FTO (fat mass and obesity associated) mRNA in offspring of lean dams regardless of diet. A short period of exercise early in life had lasting beneficial effects on body weight, adiposity and hormone profile of male offspring from obese and lean dams, despite being followed by a period of inactivity. The effects of exercise on hypothalamic appetite regulators were more marked in offspring of lean dams.

Kawajiri T, Osaki Y, Kishimoto T. Association of gene polymorphism of the fat mass and obesity associated gene with metabolic syndrome: a retrospective cohort study in Japanese workers. Yonago Acta Med 2012; 55:29-40. [PMID: 24031137 PMCID: PMC3763791] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [What about the content of this article? (0)] [Affiliation(s)] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2012] [Accepted: 05/07/2012] [Indexed: 06/02/2023]
Abstract
To investigate whether gene polymorphism of the fat mass and obesity associated gene (FTO) is associated with metabolic syndrome (MS), we used two MS criteria, the National Cholesterol Education Program-Adult Treatment panel III (NCEP-ATPIII) definition in 2003 and the Japanese definition in 2005. Subjects were respectively 859 and 865 Japanese workers at a company in Shimane Prefecture, Japan. They were non-MS individuals in 1998 and had regular health checkups between 1998 and 2006. The Cox proportional hazard regression was used to predict MS. Three SNPs in the FTO, rs9939609, rs1121980 and rs1558902, were genotyped by the TaqMan PCR assay and a retrospective study was performed. The three SNPs in the FTO were significantly associated with body mass index, and rs1121980 and rs1558902 were associated with fasting plasma glucose. MS defined by the NCEP-ATPIII definition was significantly associated with additive and dominant models of rs9939609 and rs1121980, and the dominant model of rs1558902, even after adjusting for confounding factors such as age, sex and lifestyle. MS defined by the Japanese definition was significantly associated with the additive model of rs1121980 and additive and dominant models of rs1558902 in multivariate analysis. These results suggested that FTO gene polymorphisms, rs9939609, rs1121980 and rs1558902, were associated with an increased risk of MS among Japanese workers.
