Project description:We evaluated the suitability of high-throughput transcriptomics approach to monitor terrestrial ecosystems. Free-living Mus spretus from several polluted sites of Huelva (Andalusia, SW Spain) were compared with mice from Doñana Biological Reserve (“Santa Olalla” lagoon (SOL) used as negative control). As most popular bioindicators, M. spretus is poorly represented in gene databases, therefore limiting the use of genomics in ecotoxicological studies. To solve this problem, we used microarrays produced from mRNAs of M. musculus. Specifically we used the One-Color Gene Expression Platform commercialized by Agilent.

Free-living Mus spretus from several polluted sites of Huelva (Andalusia, SW Spain) were compared with mice from DoM-CM-1ana Biological Reserve (M-bM-^@M-^\Santa OlallaM-bM-^@M-^] lagoon (SOL) used as negative control). As most popular bioindicators, M. spretus is poorly represented in gene databases, therefore limiting the use of genomics in ecotoxicological studies. To solve this problem, we used microarrays produced from mRNAs of M. musculus. Specifically we used the One-Color Gene Expression Platform commercialized by Agilent. Gene expression in Mus spretus liver was assessed in mice from 5 sites of the Spanish Southwest. Five independent experiments were performed. The arrays were hybridized with labelled cRNA samples made from pooled livers of 9 mice per sampling site. We made 4 technichal repetitions per sample.
Project description:The analysis of 2.5 million SNPs in 142 samples from the western Mediterranean area, including southern Spain, Andalusia (Huelva: 35 samples, Granada: 35), southern Portugal (36 samples) and Moroccan Berbers (Asni: 15, Bouhria: 12 and Figuig: 9).
Project description:To identify SNPs predisposing to systemic mastocytosis (SM) we performed a two stage GWAs consisting of two cohorts from the UK and Germany at stage 1 and three cohorts from Spain, Italy and Denmark at stage 2. At both stages, the SM cases were compared with publicly available controls. The control cohorts used were WTCCC and KORA at stage 1 and the Spanish National DNA bank, InChianti and Inter99 at stage 2. The data available are raw intensity files for 480 SM cases that were genotyped at stage 1. Please see our publication (Galata et al 2020) for details regarding QC of the stage 1 samples.
Project description:This study aims to understand the systemic component of psoriasis pathogenesis since psoriasis patients have higher risk of developing diesases beyond skin inflammation. In this study, we collected sigmoidal gut biopsies to profile host transcriptomic changes associated with psoriasis patients and healthy subjects. This exepriment provided transcriptomic dataset of host response and is integrated with fecal metagenomic data and flow cytometry dataset as part of the multi-omic study.
