A Guide to Applying the Sex-Gender Perspective to Nutritional Genomics
'MDPI AG', 2018Co-Authors: Dolores Corella, Oscar Coltell, Olga Portolés, Mercedes Sotos-prieto, Rebeca Fernández-carrión, Judith B. Ramirez-sabio, Vicente Zanón-moreno, Josiemer Mattei, José V. Sorlí, Jose M OrdovasAbstract:Precision nutrition aims to make dietary recommendations of a more personalized nature possible, to optimize the prevention or delay of a disease and to improve health. Therefore, the characteristics (including sex) of an individual have to be taken into account as well as a series of omics markers. The results of Nutritional Genomics studies are crucial to generate the evidence needed so that precision nutrition can be applied. Although sex is one of the fundamental variables for making recommendations, at present, the Nutritional Genomics studies undertaken have not analyzed, systematically and with a gender perspective, the heterogeneity/homogeneity in gene-diet interactions on the different phenotypes studied, thus there is little information available on this issue and needs to be improved. Here we argue for the need to incorporate the gender perspective in Nutritional Genomics studies, present the general context, analyze the differences between sex and gender, as well as the limitations to measuring them and to detecting specific sex-gene or sex-phenotype associations, both at the specific gene level or in genome-wide-association studies. We analyzed the main sex-specific gene-diet interactions published to date and their main limitations and present guidelines with recommendations to be followed when undertaking new Nutritional Genomics studies incorporating the gender perspective

the case for strategic international alliances to harness Nutritional Genomics for public and personal health
British Journal of Nutrition, 2005Co-Authors: Jim Kaput, Jose M Ordovas, Lynnette R Ferguson, Ben Van Ommen, Raymond L Rodriguez, Lindsay H Allen, Bruce N Ames, Kevin Dawson, Bruce German, Ronald M KraussAbstract:NutriGenomics is the study of how constituents of the diet interact with genes, and their products, to alter phenotype and, conversely, how genes and their products metabolise these constituents into nutrients, antinutrients, and bioactive compounds. Results from molecular and genetic epidemiological studies indicate that dietary unbalance can alter gene-nutrient interactions in ways that increase the risk of developing chronic disease. The interplay of human genetic variation and environmental factors will make identifying causative genes and nutrients a formidable, but not intractable, challenge. We provide specific recommendations for how to best meet this challenge and discuss the need for new methodologies and the use of comprehensive analyses of nutrient-genotype interactions involving large and diverse populations. The objective of the present paper is to stimulate discourse and collaboration among nutrigenomic researchers and stakeholders, a process that will lead to an increase in global health and wellness by reducing health disparities in developed and developing countries.

Genome-Wide Association Study (GWAS) on Bilirubin Concentrations in Subjects with Metabolic Syndrome: Sex-Specific GWAS Analysis and Gene-Diet Interactions in a Mediterranean Population
MDPI, 2019Co-Authors: Oscar Coltell, Portolés Olga, Fernández-carrión Rebeca, Sorlí José, Ortega Azorín Carolina, Asensio, Eva Maria, Barragán-arnal Rocío, Martínez-lacruz Raúl, González José, Zanón-moreno VicenteAbstract:Although, for decades, increased serum bilirubin concentrations were considered a threatening sign of underlying liver disease and had been associated with neonatal jaundice, data from recent years show that bilirubin is a powerful antioxidant and suggest that slightly increased serum bilirubin concentrations are protective against oxidative stress-related diseases, such as cardiovascular diseases. Therefore, a better understanding of the gene-diet interactions in determining serum bilirubin concentrations is needed. None of the previous genome-wide association studies (GWAS) on bilirubin concentrations has been stratified by sex. Therefore, considering the increasing interest in incorporating the gender perspective into Nutritional Genomics, our main aim was to carry out a GWAS on total serum bilirubin concentrations in a Mediterranean population with metabolic syndrome, stratified by sex. Our secondary aim was to explore, as a pilot study, the presence of gene-diet interactions at the GWAS level. We included 430 participants (188 men and 242 women, aged 55–75 years, and with metabolic syndrome) in the PREDIMED Plus-Valencia study. Global and sex-specific GWAS were undertaken to analyze associations and gene-diet interaction on total serum bilirubin. Adherence (low and high) to the Mediterranean diet (MedDiet) was analyzed as the dietary modulator. In the GWAS, we detected more than 55 SNPs associated with serum bilirubin at p < 5 × 10−8 (GWAS level). The top-ranked were four SNPs (rs4148325 (p = 9.25 × 10−24), rs4148324 (p = 9.48 × 10−24), rs6742078 (p = 1.29 × 10−23), rs887829 (p = 1.39 × 10−23), and the rs4148324 (p = 9.48 × 10−24)) in the UGT1A1 (UDP glucuronosyltransferase family 1 member A1) gene, which replicated previous findings revealing the UGT1A1 as the major locus. In the sex-specific GWAS, the top-ranked SNPs at the GWAS level were similar in men and women (the lead SNP was the rs4148324-UGT1A1 in both men (p = 4.77 × 10−11) and women (p = 2.15 × 10−14), which shows homogeneous genetic results for the major locus. There was more sex-specific heterogeneity for other minor genes associated at the suggestive level of GWAS significance (p < 1 × 10−5). We did not detect any gene-MedDiet interaction at p < 1 × 10−5 for the major genetic locus, but we detected some gene-MedDiet interactions with other genes at p < 1 × 10−5, and even at the GWAS level for the IL17B gene (p = 3.14 × 10−8). These interaction results, however, should be interpreted with caution due to our small sample size. In conclusion, our study provides new data, with a gender perspective, on genes associated with total serum bilirubin concentrations in men and women, and suggests possible additional modulations by adherence to MedDiet

Nutrigenetics, nutriGenomics and Mediterranean diet: a new vision for gastronomy
'ARAN Ediciones', 2018Co-Authors: Corella Dolores, Barragán-arnal Rocío, Ordovás Muñoz, José M., Coltell OscarAbstract:Tanto la nutrigenética como la nutrigenómica son disciplinas dentro de la denominada genómica nutricional, que, en sentido amplio, proporciona el marco de integración de las distintas ómicas con las ciencias de la alimentación y nutrición. Tras décadas de estudios nutrigenéticos y nutrigenómicos, se dispone de una cantidad relevante de conocimientos para plantear su aplicación en la denominada nutrición de precisión. Esta nueva disciplina plantea que hay que tener en cuenta las características particulares de la persona para proporcionar la mejor dieta para prevenir o tratar la enfermedad. Los marcadores ómicos se consideran relevantes en dicha personalización. Existen muchos alimentos, nutrientes y patrones de dieta que se han investigado en nutrigenética y nutrigenómica; entre ellos, podemos mencionar el patrón de dieta mediterránea. A pesar de la heterogeneidad en la definición de dieta mediterránea, existen varios estudios que muestran que la dieta mediterránea puede interaccionar con el genoma, disminuyendo el riesgo de enfermedad en las personas genéticamente más susceptibles. Paralelamente, algunos estudios están mostrando los mecanismos por los que la dieta mediterránea puede ejercer este efecto protector. Conocer con más detalle la susceptibilidad genética, los mecanismos epigenéticos, la influencia del metaboloma y de otras ómicas puede ser relevante en gastronomía, entendida como la práctica del arte de elegir, cocinar y comer los alimentos. Esta influencia ómica no solo podemos encontrarla en los fenotipos de salud-enfermedad, sino también en la percepción del sabor y del olor de los alimentos (las preferencias por determinadas comidas). Todo ello, bien integrado, puede contribuir al incremento del disfrute a la vez que se sigue una alimentación saludable.Both nutrigenetics and nutriGenomics are disciplines that form part of what is known as Nutritional Genomics, which, in the widest sense, provides the framework for integrating different omics with food and nutrition sciences. After decades of nutrigenetic and nutrigenomic studies, there is a large enough amount of knowledge to consider its application in so-called precision nutrition. This new discipline seeks to take into account the particular characteristics of the individual in order to provide the best diet for preventing or treating a disease. Omic markers are considered to be of importance to that personalization. There are many foods, nutrients and dietary patterns that have been researched in nutrigenetics and nutriGenomics, including the Mediterranean Diet pattern. Despite heterogeneity in defining the Mediterranean Diet, there are various studies that show that the Mediterranean Diet can interact with the genome, so reducing the risk of disease in the most genetically susceptible individuals. Likewise, several studies have recently been revealing the mechanisms through which the Mediterranean Diet may exercise this protective effect. Understanding genetic susceptibility, epigenetic mechanisms, the influence of the metabolome and other omics in more detail may be important in gastronomy, understood as the practice of selecting, cooking and eating food. This omic influence can not only be found in health-disease phenotypes, but also in food taste and smell perception and preferences for certain dishes. Considering all of these together may contribute to an increase in enjoying and at the same time pursuing healthy eating

nutriGenomics concepts and applications to pharmacoGenomics and clinical medicine
Pharmacogenomics, 2007Co-Authors: Jim Kaput, Alla Perlina, Amelia Bartholomew, Betül Hatipoğlu, Yuri NikolskyAbstract:The maintenance of health and the prevention and treatment of chronic diseases are influenced by naturally occurring chemicals in foods. In addition to supplying the substrates for producing energy, a large number of dietary chemicals are bioactive – that is, they alter the regulation of biological processes and, either directly or indirectly, the expression of genetic information. Nutrients and bioactives may produce different physiological phenotypes among individuals because of genetic variability and not only alter health, but also disease initiation, progression and severity. The study and application of gene–nutrient interactions is called Nutritional Genomics or nutriGenomics. Nutrigenomic concepts, research strategies and clinical implementation are similar to and overlap those of pharmacoGenomics, and both are fundamental to the treatment of disease and maintenance of optimal health.

Genome-Wide Association Study (GWAS) on Bilirubin Concentrations in Subjects with Metabolic Syndrome: Sex-Specific GWAS Analysis and Gene-Diet Interactions in a Mediterranean Population
MDPI, 2019Co-Authors: Oscar Coltell, Portolés Olga, Fernández-carrión Rebeca, Sorlí José, Ortega Azorín Carolina, Asensio, Eva Maria, Barragán-arnal Rocío, Martínez-lacruz Raúl, González José, Zanón-moreno VicenteAbstract:Although, for decades, increased serum bilirubin concentrations were considered a threatening sign of underlying liver disease and had been associated with neonatal jaundice, data from recent years show that bilirubin is a powerful antioxidant and suggest that slightly increased serum bilirubin concentrations are protective against oxidative stress-related diseases, such as cardiovascular diseases.

In conclusion, our study provides new data, with a gender perspective, on genes associated with total serum bilirubin concentrations in men and women, and suggests possible additional modulations by adherence to MedDiet

Genome-Wide Association Study (GWAS) on Bilirubin Concentrations in Subjects with Metabolic Syndrome: Sex-Specific GWAS Analysis and Gene-Diet Interactions in a Mediterranean Population
'MDPI AG', 2019Co-Authors: Coltell Oscar, Portolés Olga, Fernández-carrión Rebeca, Sorlí José, Ortega Azorín Carolina, Martínez-lacruz Raúl, González José, Asensio, Eva M, Barragán Rocio, Zanón-moreno VicenteAbstract:Although, for decades, increased serum bilirubin concentrations were considered a threatening sign of underlying liver disease and had been associated with neonatal jaundice, data from recent years show that bilirubin is a powerful antioxidant and suggest that slightly increased serum bilirubin concentrations are protective against oxidative stress-related diseases, such as cardiovascular diseases. Therefore, a better understanding of the gene-diet interactions in determining serum bilirubin concentrations is needed. None of the previous genome-wide association studies (GWAS) on bilirubin concentrations has been stratified by sex. Therefore, considering the increasing interest in incorporating the gender perspective into Nutritional Genomics, our main aim was to carry out a GWAS on total serum bilirubin concentrations in a Mediterranean population with metabolic syndrome, stratified by sex. Our secondary aim was to explore, as a pilot study, the presence of gene-diet interactions at the GWAS level. We included 430 participants (188 men and 242 women, aged 55⁻75 years, and with metabolic syndrome) in the PREDIMED Plus-Valencia study. Global and sex-specific GWAS were undertaken to analyze associations and gene-diet interaction on total serum bilirubin. Adherence (low and high) to the Mediterranean diet (MedDiet) was analyzed as the dietary modulator. In the GWAS, we detected more than 55 SNPs associated with serum bilirubin at p < 5 × 10-8 (GWAS level). The top-ranked were four SNPs (rs4148325 (p = 9.25 × 10-24), rs4148324 (p = 9.48 × 10-24), rs6742078 (p = 1.29 × 10-23), rs887829 (p = 1.39 × 10-23), and the rs4148324 (p = 9.48 × 10-24)) in the UGT1A1 (UDP glucuronosyltransferase family 1 member A1) gene, which replicated previous findings revealing the UGT1A1 as the major locus. In the sex-specific GWAS, the top-ranked SNPs at the GWAS level were similar in men and women (the lead SNP was the rs4148324-UGT1A1 in both men (p = 4.77 × 10-11) and women (p = 2.15 × 10-14), which shows homogeneous genetic results for the major locus. There was more sex-specific heterogeneity for other minor genes associated at the suggestive level of GWAS significance (p < 1 × 10-5). We did not detect any gene-MedDiet interaction at p < 1 × 10-5 for the major genetic locus, but we detected some gene-MedDiet interactions with other genes at p < 1 × 10-5, and even at the GWAS level for the IL17B gene (p = 3.14 × 10-8). These interaction results, however, should be interpreted with caution due to our small sample size. In conclusion, our study provides new data, with a gender perspective, on genes associated with total serum bilirubin concentrations in men and women, and suggests possible additional modulations by adherence to MedDiet.This study was partially funded by the Spanish Ministry of Health (Instituto de Salud Carlos III) and the Ministerio de Economía y Competitividad-Fondo Europeo de Desarrollo Regional (FEDER) (grants CIBER 06/03, PRX17/00500, PI16/00366, PI06/1326, and SAF2016–80532-R), the University Jaume I (grants P1–1B2013–54 and COGRUP/2016/06), the Fundació La Marató de TV3 (grant 538/U/2016), the Real Colegio Complutense at Harvard University, the Fundación MAPFRE (grant Ignacio Larramendi 2014), the Rei Jaume I Award for Medical Research 2018, the Generalitat Valenciana (grants PROMETEO2017/017, and AEST/2018/044), and the US Department of Agriculture, Agriculture Research Service (grant 8050–51000-098-00D).S

A guide to applying the sex-gender perspective to Nutritional Genomics
'MDPI AG', 2018Co-Authors: Corella Dolores, Coltell Oscar, Portolés Olga, Sotos-prieto Mercedes, Fernández-carrión Rebeca, Ramirez-sabio, Judith B., Zanón-moreno Vicente, Mattei Josiemer, Sorlí José, Ordovas, Jose M.Abstract:Precision nutrition aims to make dietary recommendations of a more personalized nature possible, to optimize the prevention or delay of a disease and to improve health. Therefore, the characteristics (including sex) of an individual have to be taken into account as well as a series of omics markers. The results of Nutritional Genomics studies are crucial to generate the evidence needed so that precision nutrition can be applied. Although sex is one of the fundamental variables for making recommendations, at present, the Nutritional Genomics studies undertaken have not analyzed, systematically and with a gender perspective, the heterogeneity/homogeneity in gene-diet interactions on the different phenotypes studied, thus there is little information available on this issue and needs to be improved. Here we argue for the need to incorporate the gender perspective in Nutritional Genomics studies, present the general context, analyze the differences between sex and gender, as well as the limitations to measuring them and to detecting specific sex-gene or sex-phenotype associations, both at the specific gene level or in genome-wide-association studies. We analyzed the main sex-specific gene-diet interactions published to date and their main limitations and present guidelines with recommendations to be followed when undertaking new Nutritional Genomics studies incorporating the gender perspectiveThis study was partially funded by the Spanish Ministry of Health (Instituto de Salud Carlos III) and the Ministerio de Economía y Competitividad-Fondo Europeo de Desarrollo Regional (FEDER) (grants CIBER 06/03, PRX17/00500, PI16/00366, PI06/1326, and SAF2016–80532-R); the University Jaume I (grants P1–1B2013–54 and COGRUP/2016/06); the Fundació La Marató de TV3 (grant 538/U/2016); the Real Colegio Complutense at Harvard University, the Generalitat Valenciana (grant PROMETEO2017/017 and AEST/2018/044) and by the US Department of Agriculture, Agriculture Research Service (8050–51000-098-00D
