The Relationship

Obesity is influenced by environmental, behavioral, and genetic factors; particularly genes related to the regulation of lipids and addictive behavior. Food craving (FC) is a physiological and behavioral response that triggers the intense desire to ingest food, particularly food with high energy, fat, and/or sweet content. Objective: To evaluate the relationship between the prevalence of FC in obese subjects and blood lipids as well as to determine the transcriptional modulation of CART, DRD2, and FTO. Method: Transverse, comparative, and randomized study including 21 obese participants (BMI, ≥30 kg/m2] and 20 normal weight participants (BMI, ≤25 kg/m2). We determined CART, DRD2, and FTO expressions; evaluated blood lipid levels; and obtained trait scores on the Food Craving Questionnaire-Trait, a multifactorial instrument validated for the Mexican population. Results: The DRD2 expression was significantly increased (p = 0.027) and the CART expression was significantly decreased (p = 0.001) in obese participants compared with normal weight participants. The FTO expression did not show significant differences. Food Craving Questionnaire-Trait showed scores of ≥72 in obese participants. Conclusions: Linear regression model analysis showed that FC is a predictor of atherogenic index (ATH), independently of BMI, and of the gene expression modulation of CART and DRD2.

ObjectiveSerum amyloid A (SAA) is a novel link between increased adipose tissue mass and low-grade inflammation in obesity. Little is known about the factors regulating its serum concentration and mRNA levels. We investigated the association between SAA and leptin in obese and normal weight subjects and analyzed the effect of weight reduction on serum SAA concentration and gene expression in adipose tissue of the obese subjects.MethodsSeventy-five obese subjects (60±7 years, body mass index (BMI) 32.9±2.8 kg/m2, mean±s.d.) with impaired fasting plasma glucose or impaired glucose tolerance and other features of metabolic syndrome, and 11 normal weight control subjects (48±9 years, BMI 23.7±1.9 kg/m2) were studied at the baseline. Twenty-eight obese subjects underwent a 12-week intensive weight reduction program followed by 5 months of weight maintenance. Blood samples and abdominal s.c. adipose tissue biopsies were taken at the baseline and after the follow-up. Gene expression was studied using real-time quantitative PCR.ResultsThe gene expressions in women and serum concentrations of leptin and SAA were interrelated independently of body fat mass in the obese subjects (r=0.54, P=0.001; r=0.24, P=0.039 respectively). In multiple linear regression analyses, leptin mRNA explained 38% of the variance in SAA mRNA (P=0.002) in the obese women. Weight loss of at least 5% increased SAA mRNA expression by 48 and 36% in men and women, but serum SAA concentrations did not change.ConclusionsThe association between SAA and leptin suggests an interaction between these two adipokines, which may have implications in inflammatory processes related to obesity and the metabolic syndrome.

AbstractWe compared metabolic biomarkers in the blood and peripheral blood mononuclear cell (PBMC) gene expression profiles among normal weight (BMI, 18·5–23 kg/m2), mildly obese (BMI, 25–27·5 kg/m2) and moderately obese Korean adult men (BMI, 27·5–30 kg/m2). High leptin, lipids (except LDL- and HDL-cholesterol) and apoB levels and low adiponectin and HDL-cholesterol levels were present in the plasma of both mildly and moderately obese subjects. Circulating levels of inflammatory cytokines and markers of insulin resistance, oxidative stress and liver damage were altered in moderately obese subjects but not in mildly obese subjects. PBMC transcriptome data showed enrichment of pathways involved in energy metabolism, insulin resistance, bone metabolism, cancer, inflammation and fibrosis in both mildly and moderately obese subjects. Signalling pathways involved in oxidative phosphorylation, TAG synthesis, carbohydrate metabolism and insulin production; mammalian target of rapamycin, forkhead box O, ras-proximate-1, RAS and transforming growth factor-β signalling; as well as extracellular matrix–receptor interaction were enriched only in moderately obese subjects, indicating that changes in PBMC gene expression profiles, according to metabolic disturbances, were associated with the development and/or aggravation of obesity. In particular, fourteen and fifteen genes differentially expressed only in mildly obese subjects and in both mildly and moderately obese subjects, respectively, could be used as early or stable biomarkers for diagnosing and treating obesity-associated metabolic disturbance. We characterised BMI-associated metabolic and molecular biomarkers in the blood and provided clues about potential blood-based targets for preventing or treating obesity-related complications.

AbstractIntroduction:Obesity is an excess of adipose tissue (AT) and is linked with increased inflammation that enhances risk of type-2 diabetes and cardiovascular disease. The BIOCLAIMS study assessed the effect of obesity on AT fatty acid composition and gene expression, and the responses of these to chronic omega-3 FA supplementation.Materials and methods:AT biopsies were collected pre- and post-12 week supplementation with 1.1 g EPA + 0.8 g DHA/day or corn oil. The composition of FA in the total lipid extract of AT from 37 normal-weight and 44 obese subjects was assessed by gas chromatography, whole AT transcriptome from 10 normal-weight and 10 obese subjects was assessed by RNA-Sequencing, and selected gene expression in AT of 27 normal-weight and 38 obese subjects was assessed by qRT-PCR.Results:789 AT genes were differentially expressed (623 upregulated, 175 downregulated) in obesity compared to normal-weight (FC > 2, P < 0.05). Differentially expressed genes included EGFL6, MMP-7 and -9, 5-LOX, WNT3 and WNT10B, DACT2, CNR1, SLC27A2 and PLA2G7, and were associated with immune and inflammatory response, cell proliferation, activation and movement, Wnt signalling, remodelling and expansion, and lipid incorporation and degradation.Chronic supplementation with EPA + DHA increased the concentration of AT EPA, DPA and DHA in normal-weight subjects (P < 0.01), and EPA in obese subjects (P = 0.006). EPA + DHA modulated the expression of 26 genes (14 upregulated, 12 downregulated) in normal-weight subjects and 7 genes (3 upregulated, 5 downregulated) in obese subjects (FC > 2, P < 0.05). Of note, EPA + DHA downregulated IGLV1-44, IGLV1-51, PROK2, and TREM1 in normal weight subjects (P < 0.05), and IGLV1-44, IGLV1-47, DACT2 and IDO1 obese subjects (P < 0.05). Genes of note upregulated by EPA + DHA included KCNH2, GCGR, SLC36A2 and FOXC2 in normal-weight subjects, and MAB21L1, LRRTM4, and COX-2, in obese subjects. Differentially expressed genes were associated with a decrease in complement activation and immunoglobulin secretion, negative regulation of cell proliferation, and positive regulation of remodelling, amino acid and glucose transport, and COX pathway metabolite synthesis.Discussion:These data indicate an altered AT transcription profile and gene expression in obesity suggesting enhanced immune and inflammatory response, tissue expansion and remodelling, and changes to lipid metabolism, as well as dysregulation in response to supplementary EPA + DHA at a gene expression level. EPA + DHA are able to modulate AT gene expression predominantly associated with reducing immune response, but obesity may involve resistance to the effects on tissue remodelling and nutrient transport.

Objective: To know the relationship between obesity and gynecology cancer. Method: This study use case control study design for 250 gynecology patients (125 controls and 125 cases) in Prof. Dr. R. D. Kandou Manado Hospital from 1 July to 30 November 2015. The data was collected by measuring Body Mass Index (BMI) and filing out selfadministered questioners. Result: From the 250 subjects, the study group (125 subjects), 72 subjects have obesity (57.6%) and 97 subjects have multiple parities (77.6%) with 58 subjects diagnosed with cervical cancer (46.4%). In the control group (125 subjects), 71 subjects have normal weight (56.8%) and 67 subjects have multiple parities (53.6%) with 64 subjects diagnosed with ovarium cysts (51.2%). Using multivariate logistic regression, the overweight and obese subjects have 7 folds higher risk to develop gynecology cancer compared to those with normal or underweight subjects. Those with multiple parities and grande multipara subjects have 3 folds higher risk to develop gynecology cancer compared with those who are nullipara and primipara. Conclusion: A significant correlation is found between obesity and gynecology cancer using multivariate logistic regression analysis (p=0.000, OR=6.9 (95% CI = 3.62-13.13).

The Relationship

Although obesity is a well-established cardiovascular risk factor, some controversy has arisen with regard to its effect on hospital mortality in patients admitted for acute coronary syndrome.Methods. Clinical and anthropometric variables were analyzed in patients consecutively admitted for acute coronary syndrome to a university hospital between 2009 and 2010, and the correlation of those variables with hospital mortality was examined.Results. A total of 824 patients with a diagnosis of myocardial infarction or unstable angina were analyzed. Body mass index was an independent factor in hospital mortality (odds ratio 0.739 (IC 95%:0.597-0.916),P=0.006). Mortality in normal weight(n=218), overweight(n=399), and obese(n=172)subjects was 6.1%, 3.1%, and 4.1%, respectively, with no statistically significant differences between the groups.Conclusions. There is something of a paradox in the relationship between body mass index and hospital mortality in patients with acute coronary syndrome in that the mortality rate decreases as body mass index increases. However, no statistically significant differences have been found in normal weight, overweight, or obese subjects.

Objective The effect of vitamin D at the transcriptome level is poorly understood, and furthermore, it is unclear if it differs between obese and normal-weight subjects. The objective of the study was to explore the transcriptome effects of vitamin D supplementation. Design and methods We analysed peripheral blood gene expression using GlobinLock oligonucleotides followed by RNA sequencing in individuals participating in a 12-week randomised double-blinded placebo-controlled vitamin D intervention study. The study involved 18 obese and 18 normal-weight subjects (of which 20 males) with mean (±s.d.) age 20.4 (±2.5) years and BMIs 36 (±10) and 23 (±4) kg/m2, respectively. The supplemental daily vitamin D dose was 50 µg (2000 IU). Data were available at baseline, 6- and 12-week time points and comparisons were performed between the vitamin D and placebo groups separately in obese and normal-weight subjects. Results Significant transcriptomic changes were observed at 6 weeks, and only in the obese subjects: 1724 genes were significantly upregulated and 186 genes were downregulated in the vitamin D group compared with placebo. Further analyses showed several enriched gene categories connected to mitochondrial function and metabolism, and the most significantly enriched pathway was related to oxidative phosphorylation (adjusted P value 3.08 × 10−14). Taken together, our data suggest an effect of vitamin D supplementation on mitochondrial function in obese subjects. Conclusions Vitamin D supplementation affects gene expression in obese, but not in normal-weight subjects. The altered genes are enriched in pathways related to mitochondrial function. The present study increases the understanding of the effects of vitamin D at the transcriptome level.

The aim of the study was to evaluate the relationship between body mass index (BMI) and body mass loss (BML) induced by thermal stress in a dry sauna. The study was conducted on a group of 674 sedentary students, 326 women and 348 men aged 19-20. The correlations between BMI scores and BML were determined. The subjects were placed in supine position in a dry sauna for two sessions of 10 minutes each with a 5-minute break. The influence of BMI on the amount of BML in the sauna was determined by nonlinear stepwise regression. The smallest BML was noted in underweight subjects; students with normal weight lost more weight, whereas the greatest BML was reported in overweight and obese subjects. Persons with a high BMI are at higher risk of dehydration, and they should pay particular attention to replenishing fluids during a visit to the sauna. The proposed equations for calculating BML based on a person's BMI can be useful in estimating the amount of fluids that should be replenished by both men and women during a visit to a dry sauna.

The Relationship

Although it was known that obesity is an independent risk factor for metabolic disorders including diabetes, the factors that link these diseases were obscure. The Hedgehog-interacting protein (Hhip) is a negative regulator in tissue remodeling, and inhibits the proliferation of adipocytes, and promotes their differentiation. In addition, Hhip was positively associated with diabetes. However, the relationship between Hhip and obesity in the human body remains unclear. An analysis of the relationship between Hhip and normal weight, overweight, and obesity levels. Participants receiving a physical checkup were recruited. Anthropometric and biochemical data were collected. Serum Hhip levels were determined by enzyme-linked immunosorbent assay (ELISA). Subjects were classified into normal-weight, overweight, and obese groups based on their body mass index (BMI). The association between Hhip and obesity was examined by multivariate linear regression analysis. In total, 294 subjects who were either of a normal weight (n = 166), overweight (n = 90), or obese (n = 38) were enrolled. Hhip concentrations were 6.51 ± 4.86 ng/mL, 5.79 ± 4.33 ng/mL, and 3.97 ± 3.4 ng/mL in normal-weight, overweight, and obese groups, respectively (p for trend = 0.032). Moreover, the regression analysis showed that BMI (β = −0.144, 95% confidence interval (CI) = −0.397−0.046, p = 0.013) was negatively associated with Hhip concentrations after adjusting for sex and age. Being overweight (β = −0.181, 95% CI = −3.311−0.400, p = 0.013) and obese (β = −0.311, 95% CI = −6.393−2.384, p < 0.001) were independently associated with Hhip concentrations after adjusting for sex, age, fasting plasma glucose, the insulin level, and other cardiometabolic risk factors. Our results showed that overweight and obese subjects had lower Hhip concentrations than those of normal weight. Being overweight and obese were negatively associated with Hhip concentrations. Hhip might be a link between obesity and diabetes.

A total of 250 young subjects, 150 normal-weight and 100 obese subjects, were recruited in the study. Genotyping of −794CATT5–8and −173 G>CMIFpolymorphisms was performed by PCR and PCR-RFLP, respectively. MIF mRNA expression was determined by real-time PCR and serum MIF levels were measured using an ELISA kit. For bothMIFpromoter polymorphisms, no significant differences in the genotype and allele frequencies between groups were observed. MIF mRNA expression was slightly higher in obese subjects than in normal-weight subjects (1.38-fold), while soluble MIF levels did not show differences between groups. In addition, we found an increase in MIF mRNA expression in carriers of the 6,6 and C/C genotypes and the 6G haplotype of the −794CATT5–8and −173 G>CMIFpolymorphisms, although it was not significant. In conclusion, this study found no relationship between obesity andMIFgene promoter polymorphisms with MIF mRNA expression in young obese subjects.

Objective Insulin resistance is a major pathophysiological link between obesity and its metabolic complications. Weight loss (WL) is an effective tool to prevent obesity-related diseases; however, the mechanisms of an improvement in insulin sensitivity (IS) after weight-reducing interventions are not completely understood. The aim of the present study was to analyze the relationships between IS and adipose tissue (AT) expression of the genes involved in the regulation of lipolysis in obese subjects after WL. Methods Fifty-two obese subjects underwent weight-reducing dietary intervention program. The control group comprised 20 normal-weight subjects, examined at baseline only. Hyperinsulinemic-euglycemic clamp and s.c. AT biopsy with subsequent gene expression analysis were performed before and after the program. Results AT expression of genes encoding lipases (PNPLA2, LIPE and MGLL) and lipid-droplet proteins enhancing (ABHD5) and inhibiting lipolysis (PLIN1 and CIDEA) were decreased in obese individuals in comparison with normal-weight individuals. The group of 38 obese participants completed dietary intervention program and clamp studies, which resulted in a significant WL and an improvement in mean IS. However, in nine subjects from this group IS did not improve in response to WL. AT expression of PNPLA2, LIPE and PLIN1 increased only in the group without IS improvement. Conclusions Excessive lipolysis may prevent an improvement in IS during WL. The change in AT PNPLA2 and LIPE expression was a negative predictor of the change in IS after WL.
