In population studies, it is considered a surrogate for obesity [1] . In large genome-wide association studies, the strongest genetic signal for BMI has been the fat mass and obesity-associated (FTO) locus [2] . Eighty-nine genetic variants within introns 1 and 2 of the FTO have been associated with BMI. Browning of adipose tissue has physiological relevance, and disorders of mitochondrial function and brown fat may play a role in pathophysiological aspects of obesity [3] . Browning adipocytes are a key site of energy expenditure; therefore, shifting adipocyte differentiation towards a brown adipocyte-like phenotype may increase energetic efficiency in mammals. Mammals have two types of adipose tissue: white adipose tissue (WAT), which is the most abundant, stores extra calories, and brown adipose tissue, which dissipates energy through mitochondrial uncoupling and the production of heat. Recently, a number of investigators have shown that there is a third type of fat cell, the ‘beige’ adipocyte. This beige cell transitions between states of energy storage and dissipation. It can be induced and is found in adult humans [4] . The potential importance of the fatty acid composition of dietary fats as a factor that plays a role in adipose tissue development and function has been actively investigated. Over the years, Ailhaud et al. [5] , Massiera et al. [6] and Pisani et al. [8] have contributed enormously to understanding the role of arachidonic acid (AA) and its metabolites derived from the cyclooxygenase pathway in increasing WAT proliferation and decreasing browning of WAT. Under isoenergetic isolipidic conditions, inclusion of AA in the diet impaired brite adipocyte recruitment in the subcutaneous WAT compared to mice fed a standard diet [7] . The data of Massiera et al. [6] regarding the fat mass show that perinatal exposure of mice to a high omega-6 [linoleic acid (LA)] fatty acid diet, as it is today in Western diets, results in a progressive accumulation of body fat across generations. This is consistent with the data showing that in humans, overweight and obesity have steadily increased over the last 30–40 years, in addition to occurring earlier in life. Today, there is more obesity in children worldwide than ever before. The inhibitory role of the omega-6 fatty acids (LA + AA) in the browning process of white fat cells has been precisely investigated.

However, it has not been genetically evaluated in Mexico, a country with admixed population, recent introduction of dairy, and a high prevalence of obesity. Thus, we aimed to determine the distribution of the LCT polymorphisms and their association with the nutritional profile of West Mexico's populations. Methods: Genotyping of 1,196 individuals (natives and mestizos) was carried out by a Taqman allelic discrimination assay. Descriptive statistics and interpopulation analyzes were performed by SPSS, Arlequin, and Structure software. Demographic, anthropometric, biochemical and dietary data were analyzed in 212 mestizos. Results: LNP genotypes mainly prevailed (CC 68.7% and GG 68.2%); both predominated in native Huicholes and Nahuas (>97.7%). Among the mestizos, the LP genotypes were associated with a higher intake of saturated fat (9.9 ± 3.9% vs. 8.5 ± 4.0%, p = 0.018; OR = 2.55, 95% CI 1.29-5.03, p = 0.006) and a daily/more frequent consumption of dairy (88.8 vs. 78.0%; p = 0.049) than LNP genotypes.

Anthropometric variables, lipid profiles, insulin-resistant profiles, reverse cholesterol transport (RCT) enzymes, HDL subfraction, and apoM polymorphism were determined.</p><p><strong>Results: </strong>In OB with T-855C polymorphism, TT genotype carriers significantly showed 6.2% higher diastolic blood pressure (DBP), 1.3% lower amount of HDL2b subfraction, and 19.7% higher lecithin-cholesterol acyltransferase (LCAT) mass than TC+CC carriers. OB subjects with the T allele of T-778C polymorphism significantly demonstrated 43% higher plasma insulin, 17.7% higher total cholesterol, 26.7% higher triglyceride, 40.7% higher leptin, 1.6% lower HDL2b, and 12.6% higher LCAT mass than those with the C allele. These results were reversed in non-OB with T-778C polymorphism regarding HDL subfractions and RCT enzymes.</p><p><strong>Conclusion: </strong>apoM T-855C and T-778C polymorphisms were found to be associated with obesity by regulating HDL metabolism, and the T alleles of apoM T-778C were shown to be more strongly correlated.</p>","PeriodicalId":54779,"journal":{"name":"Journal of Nutrigenetics and Nutrigenomics","volume":"9 5-6","pages":"306-317"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000455948","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34770918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
