Abstract
While a dramatic increase in obesity and related comorbidities is being witnessed, the underlying mechanisms of their spread remain unresolved. Epigenetic and other non-genetic mechanisms tend to be prominent candidates involved in the establishment and transmission of obesity and associated metabolic disorders to offspring. Here, we review recent findings addressing those candidates, in the context of maternal and paternal influences, and discuss the effectiveness of preventive measures.

Bai N, Lu X, Jin L, Alimujiang M, Ma J, Hu F, Xu Y, Sun J, Xu J, Zhang R, Han J, Hu C, Yang Y. CLSTN3 gene variant associates with obesity risk and contributes to dysfunction in white adipose tissue. Mol Metab 2022; 63:101531. [PMID: 35753632 PMCID: PMC9254126 DOI: 10.1016/j.molmet.2022.101531] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2022] [Revised: 06/13/2022] [Accepted: 06/17/2022] [Indexed: 11/29/2022] Open
Abstract
Objective White adipose tissue (WAT) possesses the remarkable remodeling capacity, and maladaptation of this ability contributes to the development of obesity and associated comorbidities. Calsyntenin-3 (CLSTN3) is a transmembrane protein that promotes synapse development in brain. Even though this gene has been reported to be associated with adipose tissue, its role in the regulation of WAT function is unknown yet. We aim to further assess the expression pattern of CLSTN3 gene in human adipose tissue, and investigate its regulatory impact on WAT function. Methods In our study, we observed the expression pattern of Clstn3/CLSTN3 gene in mouse and human WAT. Genetic association study and expression quantitative trait loci analysis were combined to identify the phenotypic effect of CLSTN3 gene variant in humans. This was followed by mouse experiments using adeno-associated virus-mediated human CLSTN3 overexpression in inguinal WAT. We investigated the effect of CLSTN3 on WAT function and overall metabolic homeostasis, as well as the possible underlying molecular mechanism. Results We observed that CLSTN3 gene was routinely expressed in human WAT and predominantly enriched in adipocyte fraction. Furthermore, we identified that the variant rs7296261 in the CLSTN3 locus was associated with a high risk of obesity, and its risk allele was linked to an increase in CLSTN3 expression in human WAT. Overexpression of CLSTN3 in inguinal WAT of mice resulted in diet-induced local dysfunctional expansion, liver steatosis, and systemic metabolic deficiency. In vivo and ex vivo lipolysis assays demonstrated that CLSTN3 overexpression attenuated catecholamine-stimulated lipolysis. Mechanistically, CLSTN3 could interact with amyloid precursor protein (APP) in WAT and increase APP accumulation in mitochondria, which in turn impaired adipose mitochondrial function and promoted obesity. Conclusion Taken together, we provide the evidence for a novel role of CLSTN3 in modulating WAT function, thereby reinforcing the fact that targeting CLSTN3 may be a potential approach for the treatment of obesity and associated metabolic diseases. CLSTN3 is expressed in the adipocyte fraction of human adipose tissue and mainly localizes to the plasma membrane. SNP rs7296261 in human CLSTN3 locus is associated with obesity risk. Overexpression of CLSTN3 leads to adipose tissue dysfunction in mice. CLSTN3 can attenuate catecholamine-stimulated lipolysis. CLSTN3 overexpression increases mitochondrial APP localization of mouse adipose tissue.

Abstract
INTRODUCTION Identifying eating and lifestyle behaviors prior to bariatric surgery may assist in better selecting and preparing patients and might lead to improved success rate. The current study aimed to assess eating behaviors and lifestyle trends among laparoscopic sleeve gastrectomy (LSG) candidates and to compare those trends between genders. METHODS This descriptive study was conducted in the bariatric clinic at the Haifa Assuta Medical Center. Data was gathered from medical records of LSG candidates that were evaluated before surgery in our institution between 2008 and 2011. The data included demographics, comorbidities, anthropometrics, weight management history, and lifestyle parameters. Eating pattern and eating habits were determined by eating habits questionnaires. RESULTS A total of 266 LSG surgery candidates (71.4 % female) with an average age of 40.7 ± 10.9 years and pre-surgery BMI of 42.4 ± 4.8 kg/m2 were studied. More than half of the patients have family history of obesity and their onset of obesity was before the age of 18 years (54.5 and 57.9 %, respectively). Most of the patients reported on poor eating habits and sedentary lifestyle: 65.1 % do not eat regular meals, 70.3 % skip over breakfast, 61.9 % presented loss of control eating, 45 % frequently consume sweets, and 80.1 % were classified as none active. There were no differences in eating patterns or lifestyle parameters between genders. CONCLUSION High occurrence of unhealthy eating habits and a non-active lifestyle were detected in morbid obese candidates for LSG surgery. More efforts should be directed towards nutritional and lifestyle education prior to the surgery.

Next-generation sequencing methylation profiling of subjects with obesity identifies novel gene changes. Clin Epigenetics 2016; 8:77.

Abstract
Background Obesity is a metabolic disease caused by environmental and genetic factors. However, the epigenetic mechanisms of obesity are incompletely understood. The aim of our study was to investigate the role of skeletal muscle DNA methylation in combination with transcriptomic changes in obesity. Results Muscle biopsies were obtained basally from lean (n = 12; BMI = 23.4 ± 0.7 kg/m2) and obese (n = 10; BMI = 32.9 ± 0.7 kg/m2) participants in combination with euglycemic-hyperinsulinemic clamps to assess insulin sensitivity. We performed reduced representation bisulfite sequencing (RRBS) next-generation methylation and microarray analyses on DNA and RNA isolated from vastus lateralis muscle biopsies. There were 13,130 differentially methylated cytosines (DMC; uncorrected P < 0.05) that were altered in the promoter and untranslated (5' and 3'UTR) regions in the obese versus lean analysis. Microarray analysis revealed 99 probes that were significantly (corrected P < 0.05) altered. Of these, 12 genes (encompassing 22 methylation sites) demonstrated a negative relationship between gene expression and DNA methylation. Specifically, sorbin and SH3 domain containing 3 (SORBS3) which codes for the adapter protein vinexin was significantly decreased in gene expression (fold change −1.9) and had nine DMCs that were significantly increased in methylation in obesity (methylation differences ranged from 5.0 to 24.4 %). Moreover, differentially methylated region (DMR) analysis identified a region in the 5'UTR (Chr.8:22,423,530–22,423,569) of SORBS3 that was increased in methylation by 11.2 % in the obese group. The negative relationship observed between DNA methylation and gene expression for SORBS3 was validated by a site-specific sequencing approach, pyrosequencing, and qRT-PCR. Additionally, we performed transcription factor binding analysis and identified a number of transcription factors whose binding to the differentially methylated sites or region may contribute to obesity. Conclusions These results demonstrate that obesity alters the epigenome through DNA methylation and highlights novel transcriptomic changes in SORBS3 in skeletal muscle.

Polymorphism in miR-31 and miR-584 binding site in the angiotensinogen gene differentially influences body fat distribution in both sexes. GENES AND NUTRITION 2015; 10:488. [PMID: 26319141 DOI: 10.1007/s12263-015-0488-9] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/14/2015] [Accepted: 08/17/2015] [Indexed: 01/22/2023]
Abstract
Angiotensinogen (AGT), its active fragments and microRNA-31 (miR-31) play an important role in adipocyte differentiation. AGT contains a miR-31 polymorphic binding site. We hypothesize that the rs7079 polymorphism in the miR-31/584 binding site of the AGT gene could influence body fat distribution. A total of 751 subjects (195 men, 556 women) were enrolled in the study. The rs7079 genotypes were determined by qRT-PCR. Anthropometric measurements were taken on all subjects, who were subsequently divided into two groups: obese (>30 kg m(-2)) and non-obese (<30 kg m(-2)). Linear regression models were created to determine the contributions of sex, obesity status and rs7079 to all measured parameters. Adding the rs7079 genotype significantly contributed to the linear regression model for waist circumference (p = 0.013), hip circumference (p = 0.018) and supraspinal skin-fold thickness (p = 1 × 10(-3)). Differences between sexes and between the obese and non-obese groups were observed. Waist circumference was lower in men carrying the A allele (p = 0.022); hip circumference was higher only in obese women carrying the A allele (p = 0.015). While men carrying the A allele had lower supraspinal skin-fold thickness (p = 0.022), this parameter was found to be higher in A allele carrying women (p = 3 × 10(-3)). The higher total sum of skin-fold thickness in A allele carrying women was restricted to obese individuals (p = 0.028). The presence of the A allele was associated with both lower tricipital skin-fold thickness in non-obese women (p = 0.023) and a trend of higher thickness in non-obese men (p = 0.065). Significant associations of rs7079 in the AGT gene and body fat distribution were observed. The distribution followed opposing patterns in both sexes.
