In mice, zygotic activation mainly occurs on a wide variety of genes mainly at the 2-cell stage. Long noncoding RNAs (lncRNAs) are increasingly being recognized as molecules that modulate gene expression. In this study, we performed the directional RNA-seq of MII oocytes and 2-cell embryos to identify the long noncoding RNAs activated during ZGA.

View SamplesTransgenerational inheritance of an environmentally-induced trait requires that the induced phenotype manifest in generations beyond those that were exposed as germ cells. Here we demonstrate that paternal obesity in mice confers a latent metabolic phenotype not only in F1 sons, but also in F2 grandsons who were never exposed to obesity. F1 and F2 male progeny of obese sires exhibit nearly identical metabolic phenotypes that can be explained in part by stable alterations in hepatic miR-122, a key regulator of fatty-acid metabolism. Both the physiological and molecular alterations induced by paternal obesity are inherited into F2 entirely through the male line, but become attenuated by F3. Our findings demonstrate true transgenerational inheritance of an acquired trait in mammals. The association between the acquired phenotype and levels of several abundant small noncoding RNAs in spermatozoa implicates small RNAs in the mechanism of inheritance.

View SamplesTo investigate the effect of local genetic variation on heritable traits, we developed a new recombinant inbred line (RIL) population derived from four wild isolates. The wild isolates were collected from two closely located sites in France: Orsay and Santeuil. By crossing these four genetically diverse parental isolates a population of 200 RILs was constructed. RNA-seq was used to obtain sequence polymorphisms

View SamplesSevere asthma is a collection of disease entities with varying pathophysiological characteristics (7) that result in symptoms of cough, wheeze and breathlessness, with frequent exacerbations. To address the problem of phenotypic difference and heterogeneity, the Unbiased Biomarkers for the Prediction of Respiratory Disease Outcomes (U-BIOPRED) project was set up as a public-private partnership within the framework of the Innovative Medicines Initiative (IMI), engaging academia, the pharmaceutical industry and patient groups. The goal of this investigation was to identify transcript fingerprints in whole blood that characterize patients with severe asthma and to determine whether subgroups of severe asthmatics can be identified. Furthermore, we were interested in elucidating the biological pathways that showed differences between subgroups.
