Phylogenomics Identifies an Ancestral Burst of Gene Duplications Predating the Diversification of Aphidomorpha

2019

Aphids (Aphidoidea) are a diverse group of hemipteran insects that feed on plant phloem sap. A common finding in studies of aphid genomes is the presence of a large number of duplicated genes. However, when these duplications occurred remains unclear, partly due to the high relatedness of sequenced species. To better understand the origin of aphid duplications we sequenced and assembled the genome of Cinara cedri, an early branching lineage (Lachninae) of the Aphididae family. We performed a phylogenomic comparison of this genome with 20 other sequenced genomes, including the available genomes of five other aphids, along with the transcriptomes of two species belonging to Adelgidae (a close…

Associations of the FTO rs9939609 and the MC4R rs17782313 polymorphisms with type 2 diabetes are modulated by diet, being higher when adherence to th…

2012

Background: Although the Fat Mass and Obesity (FTO) and Melanocortin-4 Receptor (MC4R) genes have been consistently associated with obesity risk, the association between the obesity-risk alleles with type 2 diabetes is still controversial. In some recent meta-analyses in which significant results have been reported, the associations disappeared after adjustment for body mass index (BMI). However gene-diet interactions with dietary patterns have not been investigated. Our main aim was to analyze whether these associations are modulated by the level of adherence to the Mediterranean Diet (MedDiet). Methods: Case-control study in 7,052 high cardiovascular risk subjects (3,430 type 2 diabetes c…

Study of the virome and microbiome associated to the proliferative verrucous leukoplakia

2017

Estudio del viroma y microbioma oral asociados con la leucoplasia verrugosa proliferativa La leucoplasia verrugosa proliferativa (LVP) es una forma maligna de leucoplasia oral (LO) que se manifiesta como parches blanquecinos hiperqueratóticos en la cavidad oral humana. Éstas son detectadas prevalentemente en mujeres de la tercera edad. La mayor parte de las LVP con el tiempo derivan en un tipo agresivo de cánceres orales, principalmente el carcinoma oral de célula escamosa (COCE). Las asociaciones con tabaco y alcohol han sido descartadas previamente y hasta la fecha, la lesión de LVP continúa sin un agente etiológico identificado, el cual se cree pudiera ser de origen vírico debido a la al…

Virus entéricos humanos en alimentos: detección y métodos de inactivación

2020

[ES] Los principales patógenos víricos que podemos adquirir ingiriendo alimentos contaminados son los norovirus, el virus de la hepatitis A y el virus de la hepatitis E que se propagan principalmente a través de la vía fecal oral. En los últimos años, la incidencia de brotes de transmisión alimentaria causados por estos patógenos ha experimentado un aumento considerable, en parte debido al comercio globalizado y a los cambios en los hábitos de consumo. Las matrices alimentarias que mayor riesgo representan para el consumidor son los moluscos bivalvos, vegetales de IV gama, frutas tipo baya y platos listos para comer. Actualmente las técnicas moleculares son las más habituales para la detecc…

Análisis genético y funcional de la frataxina y otras proteínas mitocrondriales relacionadas con ataxias cerebelosas.

2005

El déficit de frataxina es la causa principal de la ataxia de Friedreich, una enfermedad hereditaria neurodegenerativa que afecta a las neuronas sensitivas del ganglio dorsal y del tracto espinocerebelar. Desde que se describi¨® el gen responsable de la enfermedad y sobre todo gracias a la generaci¨®n de organismos modelos para su estudio, se han postulado diferentes funciones para la frataxina: homeostasis del hierro mitocondrial, almacenamiento del hierro, respuesta al estr¨¦s oxidativo. Biog¨¦nesis de los clusters Fe-S, modulaci¨®n en la actividad de la aconitasa mitocondrial y un papel en la fosforilaci¨®n oxidativa. Nuestro planteamiento ha sido que la frataxina realiza su funci¨®n en …

2015

Background Abdominal obesity (AO) is a common modifiable risk factor for certain non-communicable diseases associated with enhanced oxidative stress (OS). The objective of this work was to investigate whether the interaction between antioxidant vitamin intake and OS-related polymorphisms modulates gene-associated anthropometry in a Spanish population. Methods A total of 246 subjects with AO, and 492 age and gender matched non-AO subjects were included in the study. Anthropometric, biochemical, and OS parameters, and antioxidant dietary intake data were assessed using validated procedures. DNA from white blood cells was isolated and the genotype of seven polymorphisms from genes involved in …

Novel loci for childhood body mass index and shared heritability with adult cardiometabolic traits

2020

The genetic background of childhood body mass index (BMI), and the extent to which the well-known associations of childhood BMI with adult diseases are explained by shared genetic factors, are largely unknown. We performed a genome-wide association study meta-analysis of BMI in 61,111 children aged between 2 and 10 years. Twenty-five independent loci reached genome-wide significance in the combined discovery and replication analyses. Two of these, located nearNEDD4LandSLC45A3, have not previously been reported in relation to either childhood or adult BMI. Positive genetic correlations of childhood BMI with birth weight and adult BMI, waist-to-hip ratio, diastolic blood pressure and type 2 d…

Study of the intestinal microbiota in the HIV infection and the effect of a nutritional intervention

2017

Introducción Desde la aplicación de la Terapia Antirretroviral de Gran Actividad (TARGA) la supervivencia de los sujetos infectados con el virus de la inmunodeficiencia humana (VIH) se ha incrementado considerablemente; sin embargo, su expectativa de vida es todavía 10 años menor a la de la media de la población. Esta reducción es debida a enfermedades no relacionadas con el síndrome de inmunodeficiencia adquirida (SIDA). Entre las principales causantes de este descenso se encuentra el aumento de la incidencia de problemas cardiovasculares. Recientemente, se ha descrito que la activación inmune persistente y la inflamación crónica son dos factores implicados en la morbimortalidad de estos p…
