Introduction

Regular monitoring and implementation of early weight management interventions to address body weight and fat gain are to be encouraged, especially in individuals initiating ART with a low nadir CD4 cell count [ 715195253 ]. Whole-genome transcriptomic insights into protective molecular mechanisms in metabolically healthy obese African Americans. Lately, the use of INsTI has been associated with weight increase and clinical obesity.

Additional studies are needed to clarify the clinical relevance of this association. Meta-analysis of genome-wide association studies for body fat distribution in individuals obesiyt European ancestry. In their study, Chen et al [ 67 ] identified a group of serum metabolites, including L-kynurenine, glycerophosphocholine, glycerol 1-phosphate, glycolic acid, tagatose, methyl palmitate, and uric acid, that differed significantly between the MHO and MUO groups. Received Sep 24; Accepted Jan Metzner, N.

Taxonomic classification of bacterial 16S rRNA genes using short sequencing reads: evaluation of effective study designs. Based on an analysis in an independent cohort, they also stated that miRNAp may modulate CCL2 expression, which is a pro-inflammatory marker, upstream of the pathway leading to dyslipidemia in obesity.

Severe Obesity and Genetics

However, researchers have only recently begun to zero in on particular genetic variants that increase or decrease susceptibility to the disease. Cavassini, A. Evidence from observational and cohort studies has accumulated sinceindicating INsTI exposure as the common trait [ 10 ]. A research group led by Telle-Hansen et al [ 42 ] reported that the concentrations of very low-density lipoprotein, intermediate-density lipoprotein, and low-density lipoprotein subclasses were, overall, significantly higher in MUO individuals than in MHO individuals, with the MHNW group having the lowest values.

Genetic and behavioral determinants of waist-hip ratio and waist circumference in women twins. Geneva: World Health Organization; Importantly, recent, robust genetic associations with obesity phenotypes can thus be used to explore the differences between the metabolically deleterious and the metabolically healthy forms of obesity, which might aid in the distinction between obesity loci that lead to metabolic dysregulation and those that do not [ 70 ]. Genes are the basis for the signals and responses that guide food intake, and small changes in these genes can affect their levels of activity. Numerous linkage studies using affected, related individuals were carried out using microsatellite markers to identify regions of linkage to obesity [ 15 ]. Syndromic obesity arises from discrete genetic defects or chromosomal abnormalities at several genes, and can be autosomal or X-linked.

While changes in the environment have significantly increased obesity rates over the last 20 years, the presence or absence of genetic factors protect venetics from or predispose us to obesity. Therefore, expanding efforts to studies using samples of other ethnicities should provide excellent opportunities to discover additional obesity susceptibility loci. Importantly, in most cases we do not know which gene s in these loci are contributing to obesity, and the identity of the causative variants is currently unknown.

Mixed-effects models characterizing BMI and WHR change over time in SHCS participants initiating ART between and were developed and used to quantify the influence of demographics, clinical factors, and genetic background. A more recent study identified higher levels of alanine, glutamine, proline, asparagine, L-glutathione reduced, betaine, taurine, choline, 2-aminobutyrate, tagatose, and 2-oxoglutarate in MHO individuals than in MUO individuals[ 65 ]. A group led by Turcot analyzed the methylation levels of long interspersed nuclear element 1 LINE-1 repetitive elements in VAT samples from obese individuals with and without MetS[ 54 ]. Doumatey et al [ 48 ].

These studies have identified variants in several genes that may contribute to obesity by increasing hunger and food intake. PWS is characterized by early-onset obesity resulting from hyperphagia caused by CNS dysfunction [ 14 ]. Some genes with variants that have been associated with obesity are listed in the Table.

With the exception of rare genetic conditions associated with extreme obesity, currently, genetic tests are not useful for guiding personal diet or physical activity plans. Overall, many genes within the associated regions have been reported to fall within two broad categories: genes affecting CNS function and those that are suggested to operate peripherally, often through adipose tissue. The presence of this gene and other genes can cause:.

Hence, we sequenced actg genetics and obesity mtDNA of the proband subject, and found 47 mutations in consistency with the Eastern Snd haplogroup D4 [ 1112 ], of which were not conserved evolutionarily and are therefore not potentially linked to the disease. Changes in the composition of intestinal bacteria have been reported in a variety of disorders, including neurological, cardiovascular, and respiratory illnesses[ 74 ]. While more work remains to be done, the newly identified genetic variants may point us in the direction of valuable new drug targets for the prevention or treatment of type 2 diabetes.

Nevertheless, exposure to an obesogenic environment is necessary for actg genetics and obesity development of obesity. It has been speculated that this is due to retained insulin sensitivity, despite the metabolic challenges that overall obesity presents. The obesity gene, FTO, is of ancient origin, up-regulated during food deprivation and expressed in neurons of feeding-related nuclei of the brain. Severe Obesity and Genetics Rare single-gene defects cause severe obesity beginning in early childhood and are associated with extremely high levels of hunger. Numerous linkage studies using affected, related individuals were carried out using microsatellite markers to identify regions of linkage to obesity [ 15 ]. Genome wide association GWA study for early onset extreme obesity supports the role of fat mass and obesity associated gene FTO variants. Progress in understanding the etiology has been slow, with findings largely restricted to monogenic, severe forms of obesity.

Human adipocyte in vitro studies would be complementary to ex vivo samples and would explore any potential peripheral effects of INsTI and other antiretrovirals on the differentiation, metabolic, and secretory functions of human adipocytes in a tightly controlled environment [ 20 ]. Long-term body composition changes in antiretroviral-treated HIV-infected individuals. A different research group analyzed the expression of inflammatory and matrix remodeling genes in visceral adipose tissue VAT and liver tissue samples from MHO and MUO subjects and found similar gene expression profiles between the groups in both tissues[ 43 ]. Trajectories for MD were propagated by a shaking algorithm for each hydrogen with a non-bonded cut off every 0. Animal models would be illuminating thanks to unrestricted access to blood, adipose depots, brain and hypothalamus to elucidate the functional status of the MCS.

More precise measures eg, CT scan, dual-energy x-ray actg genetics and DXA scan or MRI are more expensive and time consuming to collect, but are expected to reduce the number of samples needed to identify robust associations to adiposity. Android fat distribution is an established, independent risk factor for CVD and type 2 diabetes [ 16 ], whereas the gynoid pattern is thought to be protective or inversely correlated [ 16 ]. However, these findings will only yield useful therapeutic interventions, once functional variants are exposed and further molecular and physiologic characterization of the genes and pathways involved is performed.

Increased actg genetics and obesity risk factors and inflammation in adipose tissue in obese subjects classified as metabolically healthy. A research group led by Telle-Hansen et al genettics 42 ] reported that the concentrations of very low-density lipoprotein, intermediate-density lipoprotein, and low-density lipoprotein subclasses were, overall, significantly higher in MUO individuals than in MHO individuals, with the MHNW group having the lowest values. The growing obesity epidemic is becoming a major public health concern, and the associated costs represent a considerable burden on societies. Marzolini, K. Download citation. An increase in the abundance of certain genera was observed depending on the type of metabolic abnormality: Blautia in cases of impaired carbohydrate metabolism and Prevotella in individuals with elevated BP and obesity. The analysis of the molecular composition of a sample is carried out through the use of nuclear magnetic resonance NMR or mass spectrometry MS.

We next carried out a phylogenetic analysis to evaluate the extent of conservation of these different mutated sites in humans compared with 16 other primate species. To date, only a few research groups have investigated the association between gut microbiota and the MHO phenotype. A year later, the same group reported that they found no association between dipeptidyl peptidase-4 DPP4 methylation levels and metabolic health status[ 55 ]. The proteome of the MHO phenotype has also been studied by a few research groups Table 4.

Therefore, expanding efforts to studies using samples of other ethnicities gneetics provide excellent opportunities to discover additional obesity susceptibility loci. Rare single-gene defects cause severe obesity beginning in early childhood and are associated with extremely high levels of hunger. For example, a key study that compared the body mass index BMI of twins reared either together or apart found that inherited factors had more influence than childhood environment.

In addition, a genetic variant of SLC39A8 rs was found to have a statistically significant association with metabolic health status in a subgroup of postmenopausal women. Body mass index was determined by dividing body weight kg by height squared m 2. From tomedian WHR and the percentage of male and female participants with abdominal obesity increased. Metabolically healthy individuals have also been observed to be less sedentary and more physically active than their unhealthy counterparts[ 14 ]. Predictions of WHR at baseline and 2. Several studies have also suggested that genetic predisposition[ 21 ], circulating micro-RNAs miRNAs [ 22 ], or gut microbiota[ 23 ] may play a role Figure 1. It can provide valuable insight into the molecular basis of a studied condition, disease, or phenotype at the protein level.

Obesity Silver Spring ; 14 — An important concern is that obesity rates are also increasing in children and adolescents all over the world [ 67 ], predisposing them to poor health from an early age. Thus, further evaluations of the full range of CNVs are needed to fully estimate their impact on obesity. Next-generation sequencing and ChIP-Seq technology can be applied to discern the epigenetic profile of the genes already associated with obesity and may also be applied in a genome-wide approach and allow integration with existing GWAS and genome sequencing data. Several of these genes also have variants that are associated with monogenic obesity, a phenomenon that has been observed in many other common conditions. Genetics and epigenetics of obesity external icon.

Serum actg genetics and obesity adipose tissue amino acid homeostasis in the metabolically healthy obese. General [ 8—10 ] and abdominal obesity have been steadily increasing in HIV-infected populations over the last decade, and weight gain frequently follows ART initiation [ 11—13 ]. Another study highlighted the importance of body fat distribution and performed a metabolomic analysis of serum samples from metabolically healthy peripherally obese and metabolically unhealthy centrally obese individuals[ 70 ]. Genome Biol.

This excess is associated with adverse health effects such as CVD, type 2 diabetes, and cancer. Acknowledgments Dr. In the presence of readily accessible food, those with the fat mass and obesity-associated gene may have challenges limiting their caloric intake.

J Acquir Immune Defic Syndr ; 78 — Science Express, Published online April 12, The latest study found that variations in or near the FTO gene are also associated with greater risk of type 2 diabetes, which is likely related to an increased predisposition to obesity. Distinct large-scale genome-wide association study analysis unveiled MC4R polymorphic gene variants associated with weight gain [ 12 ]. Consistent with previous data [ 81113 ], the BMI and WHR models revealed an average continuous gain over the study period, more important during the early years after ART initiation.

Genetic studies of body mass index yield new insights for obesity biology. Moreover, miRNA profiling studies have identified several molecules that are characteristic of the MHO phenotype, some of which are involved in processes such as cell-cell adhesion, translational initiation, and the apoptotic process. Individuals with diabetes mellitus, hypertension, hyperlipidemia, coronary artery disease, valvular or congenital heart disease, cardiomyopathy, atrial fibrillation, and heart failure were excluded from the study. Previously, CD4 nadir has been recorded as predictor of weight gain after ART start by us [ 8 ] and others [ 11133435 ]. There is emerging evidence of an association between weight gain and current widely used antiretroviral drugs, such as integrase strand transfer inhibitors INSTI and tenofovir alafenamide TAF [ 20—24 ].
