Methylation levels of LEP and POMC genes after intervention with dietary folate and hazelnut oil in the lipid profile of overweight women

Abstract BackgroundObesity contributes to several cardiometabolic diseases, such as dyslipidemia, as a result of an unhealthy lifestyle and genetic factors. The methylation profile of genes involved in appetite control and metabolism, such as LEP (leptin) and POMC (proopiomelanocortin) and altered lipid levels can contribute to obesity, and these epigenetic changes have been associated with the effects of diet composition. The objective of this study was to evaluate the methylation levels of LEP and POMC genes and lipid profile values after intervention with dietary folate and hazelnut oil in overweight women.MethodsDouble-blind, placebo, controlled intervention study with 40 overweight adult women. Participants were randomized into four groups for 8 weeks: G1, 300 g of vegetables and 191 µg / day of folate and hazelnut oil; G2, 300 g of vegetables and 191 µg / day of folate and placebo; G3, 300 g of vegetables and 94 µg / day of folate and hazelnut oil; G4, the individuals were only accompanied. In addition to the levels of methylation, food consumption, anthropometric measurements, biochemical variables of lipid profile were evaluated.ResultsAfter the intervention, the participants presented reduction in the methylation levels of the studied genes in the three intervention groups in the LEP gene: G1 (p = 0.00), G2 (p = 0.00) and G3 (p = 0.00); in the POMC gene: G1 (p = 0.01), G2 (p = 0.02) and G3 (p = 0.01), and in the lipid profile, G1 reduced the levels of LDL-c (p = 0.04), HDL-c (p = 0.00) and Triglycerides (p = 0.04); in G3 there was a reduction in total cholesterol levels (p = 0.00), LDL-c (p = 0.00) and HDL-c (p = 0.00), and in G4 there was a reduction in total cholesterol values (p = 0.00), LDL-c (p = 0.00), HDL-c (p = 0.00) and triglycerides (p = 0.00), and also, an association in G2 between the POMC methylation levels with triglycerides (p = 0.00).ConclusionThe study provided evidence of a normocaloric intervention with dietary folate and hazelnut oil supplementation on the methylation levels of LEP and POMC genes and the role they can play in lipid metabolism.Trial registrationISRCTN, NCT04523532.

Abstract Background We aimed to assess the overall cardiovascular and metabolic effect of the switch to three different single tablet regimens (STRs) [tenofovir alafenamide/emtricitabine/rilpivirine (TAF/FTC/RPV), TAF/FTC/elvitegravir/cobi (TAF/FTC/EVG/cobi) and ABC/lamivudine/dolutegravir (ABC/3TC/DTG)] in a cohort of people living with HIV/AIDS (PLWH) under effective ART. Methods All PLWH aged above 18 years on antiretroviral treatment with an HIV-RNA < 50 cp/mL at the time of the switch to TAF/FTC/RPV, TAF/FTC/EVG/cobi and ABC/3TC/DTG were retrospectively included in the analysis. Framingham risk score modification after 12 months from the switch such as lipid profile and body weight modification were assessed. The change from baseline to 12 months in mean cardiovascular risk and body weight in each of the STR’s group were assessed by means of Wilcoxon signed-rank test whereas a mixed regression model was used to assess variation in lipid levels. Results Five-hundred and sixty PLWH were switched to an STR regimen of whom 170 (30.4%) to TAF/FTC/EVG/cobi, 191 (34.1%) to TAF/FTC/RPV and 199 (35.5%) to ABC/3TC/DTG. No difference in the Framingham cardiovascular risk score was observed after 12 months from the switch in each of the STR’s groups. No significant overtime variation in mean total cholesterol levels from baseline to 12 months was observed for PLWH switched to ABC/3TC/DTG [200 (SD 38) mg/dl vs 201 (SD 35) mg/dl; p = 0.610] whereas a significant increment was observed in PLWH switched to TAF/FTC/EVG/cobi [192 (SD 34) mg/dl vs 208 (SD 40) mg/dl; p < 0.0001] and TAF/FTC/RPV [187 (SD 34) mg/dl vs 195 (SD 35) mg/dl; p = 0.027]. In addition, a significant variation in the mean body weight from baseline to 12 months was observed in PLWH switched to TAF/FTC/EVG/cobi [72.2 (SD 13.5) kilograms vs 74.6 (SD 14.3) kilograms; p < 0.0001] and TAF/FTC/RPV [73.4 (SD 11.6) kilograms vs 75.6 (SD 11.8) kilograms; p < 0.0001] whereas no difference was observed in those switched to ABC/3TC/DTG [71.5 (SD 12.8) kilograms vs 72.1 (SD 12.6) kilograms; p = 0.478]. Conclusion No difference in the cardiovascular risk after 1 year from the switch to these STRs were observed. PLWH switched to TAF/FTC/EVG/cobi and TAF/FTC/RPV showed an increase in total cholesterol levels and body weight 12 months after the switch.

Pap Method

Red dragon fruit (Hylocereus polyrhizus) peel contains anthocyanin, fiber and vitamin C, so it can be used to improve lipid profile in dyslipidemia. The peel of the dragon fruit is not durable, so in this study we used freeze-dried dragon fruit peel. The aim of this study was to prove that the administration of the red dragon fruit peel in a dose of 0.72 g/200 g BW, 1.08 g/200 g BW, and 1.44 g/200 g BW of rat per day for 28 days may improve lipid profile in male wistar strain white rats with high-fat diet. Lipid profiles were studied by examining of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides. This was a pure experimental study using randomized post test only control group design. This study used experimental animal of 30 male wistar strain white rats which were divided into five groups. Measurements of total, LDL, and HDL cholesterol levels were done by CHOD-PAP method, while triglyceride level was measured with GPO-PAP method. Data were analyzed statistically by One Way Anova test. The results of this study indicated that giving the peel of red dragon fruit as much as 0.72 g lowered total cholesterol levels, 1.08 g lowered total and LDL cholesterol levels, and 1.44 g lowered total cholesterol, LDL cholesterol, triglyceride levels, and raised HDL cholesterol level. Red dragon fruit peel can be used alternatively to improve lipid profile in dyslipidemia.

e19634 Background: Cancer patients with cachexia symptoms often show a lipid profile disorder, consisting in severe hypertriglyceridemia due to increased circulating free fatty acids and variable total cholesterol levels, decreased activity of lipoprotein lipase and increased lipolysis, which is correlated with proinflammatory cytokines levels, particularly IL-6 and TNFα. Recent evidence further confirms impairment of adipose tissue metabolism in inflammatory condition like cancer cachexia. The aim of this study was to assess the effect of nutritional supplementation with Omega 3 fatty acids (EPA and DHA) in the form of Krill Oil, on main parameters of blood lipid profile and on IL-6 and TNFα blood levels. Methods: In 2011, 34 IV stage cachectic patients (M/F 20/14; age range 55-85 y) with cancer at different sites were enrolled. 21 healthy subjects were studied as controls. All patients had high blood tryglicerides, low total cholesterol levels , high levels of blood IL-6 and TNFα compared to controls. Patients received 3 capsules (3 g/day) of krill oil (Superba™ Krill Oil, Aker Biomarine, Norway), which is an oil extract from the crustacean krill (Euphausia Superba) which contains Omega-3 series unsaturated fatty acids in phospholipidic form, of which 98 % are EPA and DHA mainly in phospholipid form. Treatment duration was 2 months. Results: A significant reduction of tryglicerides blood levels (148.23 ± 88.06 vs 114 ± 55.8 mg/dl) and a significant improvement of HDL cholesterol (42.5 ± 15.6 vs 60.9 ± 12.3 mg/dl) and Total Cholesterol (135.6 ± 46.3 vs 159 ± 41.1 mg/dl) was observed after treatment. Cytokines Il-6 and TNFα blood levels did not change significantly after treatment Conclusions: Nutritional supplementation with krill oil showed a positive activity in the regulation of blood lipid profile, involving different metabolic and inflammatory pathways, probably mainly affecting hormone-sensitive lipase activity. Our data suggest that krill oil could be useful in multi-targeted combined pharmaco-nutritional approaches to treat cancer-cachexia. Additional phase III clinical studies are warranted.

Introduction. The aim of this study was to estimate if negative lifestyle habits such as alcohol consumption, smoking and physical inactivity affect the lipid profile values. Material and methods. The study included 250 workers on regular examination in the Gradiska Health Center in the period from 2001 to 2002. There were 113 (45.2%) men and 137 (54.8%) women. The examinees were divided into three groups according age (25-39, 40-49 and 50-60 respectively). Standard laboratory methods were used to establish the following: total cholesterol, triglyceride and HDL-cholesterol level, LDL cholesterol, atherosclerosis index (AI) and total cholesterol/HDL cholesterol. Results Using a questionnaire, we have found out that out of 250 examinees 48.80% consume alcohol regularly, 50.80% are smokers and 36% are physically. The mean total cholesterol was high in all groups and it was 6.41 mmol/l. The mean triglyceride level was 1.88 mmol/l and mean HDL cholesterol was 1.48 mmol/l, I A was 2.99 and total cholesterol/HDL cholesterol ratio was 4.69. Statistical analysis showed that there was a statistically significant relationship between triglyceride values and alcohol consumption, smoking and physical activity (p<0.05). Also, we showed that there was a statistically high relationship between HDL cholesterol values, AJ, total cholesterol/HDL cholesterol and smoking in the examined groups (p<0.01). Discussion In our study the lipid profile parameters were above the desired levels, probably due to unhealthy lifestyle, including smoking, alcohol consumption and insufficient physical activity. Our results are in concordance with the results of similar studies. Conclusion It is of utmost importance to take steps to improve lifestyle habits of our population.

Brown Adipose

IntroductionPositive regulatory domain containing 16 (PRDM16) protein represents the key regulator of brown adipose tissue (BAT) development. It induces brown fat phenotype and represses white adipose tissue specific genes through the association with C-terminal binding co-repressor proteins (CtBP1 and CtBP2). In healthy adults presence of BAT has been associated with lower glucose, total cholesterol and LDL (low-density lipoprotein) cholesterol levels. Our aim was to analyze the association of PRDM16 gene (rs12409277) and CtBP2 gene (rs1561589) polymorphisms with body mass index (BMI), fasting glucose level and lipid profile of adolescents.Material and methodsOur study included 295 healthy school children, 145 boys (49.2%) and 150 girls (50.8%), 15 years of age. Genotypes for the selected polymorphisms were detected by the real-time PCR method. Age, gender, height, weight, lipid profile (total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides) and fasting glucose levels were recorded.ResultsWe did not find a statistically significant association of rs12409277 and rs1561589 polymorphisms with BMI, fasting glucose and lipid profile of adolescents. We further analyzed the combined effect of the two SNPs and the statistical analysis showed that carriers of CT genotype of rs12409277 polymorphism and GG genotype of rs1561589 polymorphism had significantly lower total cholesterol (p = 0.001) and LDL cholesterol (p = 0.008) levels compared to all other groups of genotypes.ConclusionsOur study suggests that rs12409277 and rs1561589 polymorphism might have an influence on total and LDL cholesterol levels in adolescents. Larger studies should be performed in order to confirm our results.

Background: Several studies have reported elevated blood cholesterol levels among persons who regularly smoke cigarettes and lowered blood cholesterol levels among persons quitting smoking. Other studies have also shown that smoking lowers high density lipoprotein level, resulting in an increased risk of coronary heart disease. Smoking also leads to increase in LDL cholesterol and triglyceride levels. The objective was to study serum lipid profile in smokers and non-smokers.Methods: A cross sectional comparative study was carried in 100 subjects. The subjects were divided into two groups. First group consisted of 25 nonsmokers and second group of 75 smokers. The group of 75 smokers was again divided into three equal sub groups of 25 each depending upon the duration and intensity of smoking. Concentration of serum total cholesterol and HDL was determined by Zak’s method. Concentration of serum LDL and VLDL cholesterol was determined by Friedwald’s formula. Concentration of serum triglyceride level was determined by enzymatic end point peroxidase coupled method.Results: All the values of lipid profile i.e., total cholesterol, triglycerides, LDL, VLDL were found to be significantly higher among the smokers compared to the non-smokers. HDL value was significantly lower among smokers. As the degree of smoking increased from mild to heavy smokers, the values of total cholesterol, triglycerides, LDL and VLDL increased. The degree of smoking was inversely proportional to HDL values i.e., the HDL value decreased as the smoking degree increased.Conclusions: Thus, it can be said based on the present study that smoking affects and deranges the lipid profile of the person.

Lipid Parameters

The impacts of thyroid hormones (TH) on lipid profile in euthyroid adults have gained much attention. It is currently unknown whether BMI influences such interaction. In the present study, we investigate the role of BMI in modulating the association between TH and lipid parameters in 1372 euthyroid healthy adults. Our results show that thyroid parameters are differentially associated with lipid profile. FT3 is positively correlated with total cholesterol (β=0.176±0.046, P<0.001) and LDL cholesterol levels (β=0.161±0.040, P<0.001). FT4 is negatively correlated with TG (β=−0.087±0.029, P<0.01) while positively correlated with HDL cholesterol levels (β=0.013±0.005, P<0.01). TSH is positively associated with TG (β=0.145±0.056, P<0.05) and total cholesterol levels (β=0.094±0.030, P<0.01). Importantly, BMI modulates the effect of TH on lipid profile: the interaction of FT4 and BMI and the interaction of FT3 and BMI reach statistical significance in predicting TG and HDL cholesterol levels, respectively. Stratified according to BMI levels, most associations between TH and lipid profile are significant only in normal-weight group. In conclusion, in euthyroid adults, high normal FT3, TSH levels, and low normal FT4 levels are associated with unfavorable lipid profile. BMI mediates the effect of thyroid function on lipid profile in euthyroid adults.
