Affymetrix Porcine Genome Array (porcine)
Description
The use of cDNA microarrays has made it possible to analyze expression of thousands of genes simultaneously. We employed microarray gene expression profiling of porcine cDNA to compare myocardial gene expression in infarct core and remote myocardium at 1 week (n=3), 4 weeks (n=3), and 6 weeks (n=3) after surgically induced myocardial infarction (MI) and in sham-operated controls (n=3). More than 8,000 cDNA sequences were identified in myocardium that showed differential expression in response to MI. Different temporal and spatial patterns of gene expression were recognized in the infarct core tissue within this large set of data. Microarray gene profiling revealed candidate genes, some of them described for the first time, which elucidate changes in biological processes at different stages after MI.

Description
Early establishment of the apical-basal axis is prerequesite for correct embryonic development in Arabidopsis. The hypophysis is derived from the basal cell of the early embryo and is indispensible for root development; it gives rise to the root quiescent center and the central columella. Arabidopsis pvip1 pvip2 mutants show defects in embryonic root development and give rise to rootless seedlings.

Description
RNA-Seq profiling of MCF-7 and MDA-MB-231. We profiled RNA expression in the estrogen-receptor-positive (ER+) MCF-7 and the triple-negative MDA-MB-231 breast cancer cells. The objective was to find genes differentially expressed between these cell lines as potential drivers of invasiveness of the triple-negative MDA-MB-231. We further utilized the identified differential genes to validate expression-responsive module of non-canonical Wnt signaling pathway. Overall design: 2 biological replicates of MCF-7 and 3 biological replicates of MDA-MB-231

Description
RNA-Seq profiling of estrogen-receptor-positive MCF-7 cell lines with different perturbations of non-canonical WNT signaling . The MCF-7 cells were either transfected with an empty vector (pcDNA) or with a ROR2 overexpression construct, in parallel with or without stimulation with recombinant WNT5A. The objective was to find expression-responsive targets of these perturbations as potential drivers of increased cell invasiveness. Overall design: Four conditions of MCF-7 cells each in 3 replicates: 1. empty vector (pcDNA), 2. empty vector (pcDNA) with WNT5A stimulation, 3. ROR2 overexpression construct, 4. ROR2 overexpression construct with WNT5A stimulation

Description
N6-methyladenosine RNA (m6A) is the most abundant internal mRNA modification in mammals. While its role in the regulation of posttranscriptional gene expression is beginning to be unveiled, its function during development of complex organisms is poorly understood. Here, we identify Spenito as a novel member of the methyltransferase complex and show that m6A in Drosophila is necessary for proper synaptic growth, and in regulation of early steps of pre-mRNA splicing. Splicing of Sex-lethal and of its downstream targets are defective in animals lacking m6A, revealing also important roles in sex determination and dosage compensation. Finally, we implicate the nuclear m6A reader protein, YT521-B, as a crucial effector of m6A modifications in vivo. Altogether, our work provides important novel insights into m6A biology through identification and characterization of both m6A-writing and -reading proteins in Drosophila and their effects on splicing, neurogenesis and sex-determination within the context of the whole animal. Overall design: RNA seq in Drosophila melanogaster (flies) (3 Conditions, triplicates)

Description
Narcolepsy is a sleep disorder characterized by excessive daytime sleepiness and attacks of muscle atonia triggered by strong emotions (cataplexy). The best biological marker of narcolepsy is orexin deficiency with dramatic loss in hypothalamic orexin-producing neurons. Together with a tight HLA and T-cell receptor alpha(5) association, narcolepsy is believed to be autoimmune although all attempts to prove it have failed.To characterize orexin specific peptides we produced a transgenic mouse model to access to the orexin neurons transcription profile. We generated BAC-based transgenic mice by replacing the orexin coding sequence by a flag-tagged poly(A) binding protein (Pabp1) cDNA sequence. The basis of this construct is to take advantage of the ability of Pabp1 to bind to the poly(A) tails of mRNAs in vivo. Thus mRNAs from orexin cells are expected to be enriched by cross-linking them to the flag-tagged PABP and then co-immunoprecipitating this complex with a specific anti-flag monoclonal antibody.
