Abstract
Long non-coding RNAs (lncRNAs) have been shown to be critical biomarkers or therapeutic targets for human diseases. However, only a small number of lncRNAs were screened and characterized. Here, we identified 15 lncRNAs, which are associated with fatty liver disease. Among them, APOA4-AS is shown to be a concordant regulator of Apolipoprotein A-IV (APOA4) expression. APOA4-AS has a similar expression pattern with APOA4 gene. The expressions of APOA4-AS and APOA4 are both abnormally elevated in the liver of ob/ob mice and patients with fatty liver disease. Knockdown of APOA4-AS reduces APOA4 expression both in vitro and in vivo and leads to decreased levels of plasma triglyceride and total cholesterol in ob/ob mice. Mechanistically, APOA4-AS directly interacts with mRNA stabilizing protein HuR and stabilizes APOA4 mRNA. Deletion of HuR dramatically reduces both APOA4-AS and APOA4 transcripts. This study uncovers an anti-sense lncRNA (APOA4-AS), which is co-expressed with APOA4, and concordantly and specifically regulates APOA4 expression both in vitro and in vivo with the involvement of HuR.

Abstract
Bariatric surgery is the most successful strategy for treating obesity, yet the mechanisms for this success are not clearly understood. Clinical literature suggests that plasma levels of apolipoprotein A-IV (apoA-IV) rise with Roux-en-Y gastric bypass (RYGB). apoA-IV is secreted from the intestine postprandially and has demonstrated benefits for both glucose and lipid homeostasis. Because of the parallels in the metabolic improvements seen with surgery and the rise in apoA-IV levels, we hypothesized that apoA-IV was necessary for obtaining the metabolic benefits of bariatric surgery. To test this hypothesis, we performed vertical sleeve gastrectomy (VSG), a surgery with clinical efficacy very similar to that for RYGB, in whole-body apoA-IV knockout (KO) mice. We found that VSG reduced body mass and improved both glucose and lipid homeostasis similarly in wild-type mice compared with apoA-IV KO mice. In fact, VSG normalized the impairment in glucose tolerance and caused a significantly greater improvement in hepatic triglyceride storage in the apoA-IV KO mice. Last, independent of surgery, apoA-IV KO mice had a significantly reduced preference for a high-fat diet. Altogether, these data suggest that apoA-IV is not necessary for the metabolic improvements shown with VSG, but also suggest an interesting role for apoA-IV in regulating macronutrient preference and hepatic triglyceride levels. Future studies are necessary to determine whether this is the case for RYGB as well.

Abstract
BACKGROUND REV-ERBα has been shown to regulate adipogenesis and lipid metabolism as well as to link the circadian timing system to whole body metabolic homeostasis. We thus tested whether polymorphisms in REV-ERBα could be associated with metabolic phenotypes in human population samples. METHODS We analyzed the associations between 5 REV-ERBα polymorphisms and anthropometric (body weight, body mass index (BMI), waist and hip circumferences), biochemical (plasma lipid, glucose and insulin levels) and clinical (systolic and diastolic blood pressure) variables in three population-based studies (MONICA Lille n=1155 adults, MONA LISA Lille n=1170 adults and HELENA n=1155 adolescents). We assessed in vitro, the potential influence of one REV-ERBα polymorphism in transient transfection assays using two different cell lines. RESULTS We observed significant and consistent associations between the T minor allele of the REV-ERBα rs2071427 polymorphism (located in intron 1) and higher BMI (mean allele effect=+0.33 kg m(-2)) in the MONICA Lille (P=0.02), MONA LISA (P=0.02) and HELENA (P=0.03) studies. The odds ratios for obesity associated with this allele were 1.67 (1.00-2.79) (P=0.05) in MONICA Lille, 1.29 (1.01-1.65) (P=0.04) in MONA LISA Lille and the odds ratio for overweight was 1.48 (1.08-2.03) (P=0.01) in HELENA. In transfection experiments in human hepatocyte-derived cell lines, the REV-ERBα intron 1 directed the transcription of a luciferase reporter gene independently of the rs2071427 polymorphism. CONCLUSION Our results suggest that the REV-ERBα rs2071427 polymorphism modulates body fat mass in both adult and young people.

Abstract
BACKGROUND Thyroid hormones (THs) exert multiple biological roles including effects on the cardiovascular system (lipid profile, blood pressure (BP) and cardiac output). The lipid-lowering actions of TH are mediated by the TH receptor-β whereas the mechanisms explaining the BP variations concomitant with the thyroid disorders are less understood. As the TH receptor-α (TR-α) has been associated with many of TH actions on the cardiovascular system in mice models, we hypothesized that it could be involved in the latter. We thus tested whether polymorphisms in TR-α (THRA gene) could be associated with BP level variation. Secondarily, we tested for association with coronary heart disease (CHD) risk. METHODS We analyzed the associations between five THRA polymorphisms and (i) BP level in two population-based studies (MONICA Lille n = 1,155; MONICA Toulouse n = 1,170) and (ii) the risk of CHD in two case-control studies (Lille CHD n = 558 cases/568 controls; PRIME n = 527 cases/584 controls). RESULTS Individuals carrying the rs939348 T allele had higher systolic BP (~+1.3 mm Hg) than CC individuals in both the MONICA Lille (P = 0.02) and Toulouse (P = 0.03) studies. The odds ratio (OR) for hypertension was 1.25 (P = 0.02) in the combined sample. Concerning the CHD risk, no significant association could be detected. CONCLUSIONS For the first time, our study showed associations between the THRA rs939348 polymorphism and systolic BP and the risk of hypertension but not with CHD, although we admit that the statistical power available to study any relationship with CHD was very limited. Further larger association studies are needed to confirm our findings.

Abstract
We investigated the association between the rs9939609 (T>A) polymorphism in the FTO (fat mass- and obesity-associated) gene and obesity- and type 2 diabetes mellitus-related phenotypes in the French Multinational MONItoring of Trends and Determinants in CArdiovascular Disease (MONICA) Study (n = 3367). In the study, TA or AA subjects had higher body mass index (BMI) (P = .017), waist circumference (P = .017), and hip (P = .01) circumference in an A allele dose-dependent manner. The A allele was also significantly associated with higher plasma insulin levels (P = .05), higher insulin resistance index (homeostasis model assessment) (P = .02), and higher systolic blood pressure (P = .003); but these associations disappeared after adjustment for BMI. In the study, 598 subjects were obese (BMI >or=30 kg/m(2)); and 2769 subjects were not obese (BMI <30 kg/m(2)). Subjects bearing the A allele of rs9939609 had a higher risk of obesity (adjusted odds ratio [95% confidence interval] = 1.29 [1.06-1.58], P = .01) compared with TT subjects. Moreover, the homozygous AA genotype of rs9939609 was associated with a higher risk of type 2 diabetes mellitus (odds ratio = 1.45 [1.05-1.99], P = .02, 283 subjects with and 2601 subjects without type 2 diabetes mellitus), independently of BMI. In conclusion, the role of the A allele of the FTO rs9939609 polymorphism on the risk of obesity and type 2 diabetes mellitus was confirmed in the French MONICA Study.

Association between angiopoietin-like 6 (ANGPTL6) gene polymorphisms and metabolic syndrome-related phenotypes in the French MONICA Study. DIABETES & METABOLISM 2009; 35:287-92.

Abstract
AIM Although the ANGPTL6 (angiopoietin-like 6) gene product is now known to be involved in the regulation of fat mass and insulin sensitivity in mice, its physiological functions in humans have yet to be determined. METHODS Subjects from the population-based French MONICA Study (n=3402) were genotyped for single nucleotide polymorphisms (SNPs) in ANGPTL6, and associations with anthropometric or biochemical phenotypes were looked for. RESULTS On evaluating the frequency of 17 ANGPTL6 SNPs in 100 randomly selected subjects on the basis of linkage disequilibrium mapping, four SNPs (rs6511435, rs8112063, rs11671983 and rs15723) were found to cover more than 95% of the known ANGPTL6 genetic variability. Subjects from the entire MONICA Study were then genotyped for these four SNPs. No significant association was detected for rs11671983 and rs15723. In contrast, the G allele of rs8112063 was associated with lower plasma glucose levels (P=0.009). Also, obese subjects carrying the G allele of rs6511435 had higher plasma insulin levels than AA subjects (P=0.0055). Moreover, the G allele of rs6511435 tended to be associated with a 20% higher risk of the metabolic syndrome (P=0.034). However, when false discovery rate testing (40 tests) was applied, these associations were no longer statistically significant. CONCLUSION These findings constitute the first study in humans of ANGPTL6 genetic variability. Although there was no evidence that polymorphisms in ANGPTL6 might be significantly associated with the metabolic syndrome-related phenotypes, a weak association of these polymorphisms with these parameters cannot be excluded. Further association studies are needed to arrive at any definite conclusions.

Abstract
Brain natriuretic peptide (BNP/NPPB) is a member of the natriuretic family involved in the regulation of blood pressure and blood volume as well as lipolysis control in human fat cells. Thus BNP may play a role in energy metabolism and metabolic diseases. We therefore assessed the association between the BNP promoter T-381C polymorphism and risk of type 2 diabetes and metabolic and BNP expression traits in several population samples. In French population-based samples (n = 3216), we found that individuals bearing the -381CC genotype had lower (P = 0.005) fasting glucose levels than -381TC or -381TT individuals. Moreover, the -381CC genotype was less frequent in individuals with type 2 diabetes (n = 280, 13.6%) or with impaired fasting glucose (n = 248, 12.9%) compared with normoglycaemic individuals (n = 2485, 17.8%). The adjusted odds ratio (OR) (95% CI) of type 2 diabetes for -381CC individuals was 0.69 (0.47-1.00), P = 0.05, when compared with -381T allele bearers. We replicated this association in four additional case-control studies for type 2 diabetes. The overall OR (95% CI) of type 2 diabetes was 0.85 (0.76-0.96), P = 0.008, (under a recessive model) (3593 cases and 6646 controls in total). We also found that the -381C allele was associated with higher plasma BNP concentrations (P = 0.015, n = 634) and higher BNP promoter activity in reporter gene assays. Collectively, these data suggest that relatively high BNP expression may protect against type 2 diabetes in humans.
