Proteome dataset of sea bass (Dicentrarchus labrax) skin-scales exposed to fluo...
Anjos, Liliana; Pinto, Patrícia I. S.; Santos, Soraia; Estêvão, M. Dulce; Santa, Cátia; Manadas, Bruno; Canário, Adelino V. M.; Power, Deborah M.Contamination of aquatic ecosystems with anthropogenic pollutants, including pharmaceutical drugs, is a major concern worldwide. Aquatic organisms such as fish are particularly at risk of exposure to pollutants. The surface of fish is the first point of contact with pollutants, but few studies have considered the impact of pollutants on the skin-scale barrier. The present proteome data are the basis of the find...
Fish lysozyme gene family evolution and divergent function in early development
Li, Lisen; Cardoso, João C. R.; Félix, Rute; Mateus, Ana Patricia; Canario, Adelino; Power, Deborah M.Lysozymes are an ancient group of antimicrobial enzymes of the innate immune system. Here we provide a comparative analysis of the evolution and function of lysozymes during early development in fish, the most speciose vertebrate group. In fishes, lineage and species-specific evolution of both C-type (chicken or conventional) and G-type (goose type) genes occurred. Phylogenetic analysis revealed that the teleos...
Memorium - Professor Ian Henderson
Power, Deborah M.; Dores, Robert M.; Sheridan, Mark; Balment, RichardWe regret to report the death of Professor Ian Henderson an internationally recognised scientist who contributed enormously to the field of comparative endocrinology. He made major scientific discoveries and was also a tremendous servant to the scientific community through his international collaborations, organisation of international conferences, and in more recent years as Co-editor in-Chief of the journal o...
Ultra-low noise PEDOT:PSS electrodes on bacterial cellulose: a sensor to access...
Inácio, Pedro M.C.; Medeiros, Maria C.R.; Carvalho, Tiago; Félix, Rute C.; Mestre, Ana; Hubbard, Peter C.; Ferreira, Quirina; Morgado, JorgeThis study is focused on the particular advantages of organic-based devices to measure cells that do not generate action potentials, also known as non-electrogenic cells. While there is a vast literature about the application of organic conductors to measure neurons, cardiomyocytes and brain tissues, electrical measurements of non-electrogenic cells are rare. This is because non-electrogenic cells generate weak...
Experimental data from flesh quality assessment and shelf life monitoring of hi...
Anjos, Liliana; Pinto, Patricia I. S.; Tsironi, Theofania; Dimopoulos, George; Santos, Soraia; Santa, Cátia; Manadas, Bruno; Canario, AdelinoFresh fish are highly perishable food products and their short shelf-life limits their commercial exploitation and leads to waste, which has a negative impact on aquaculture sustainability. New non-thermal food processing methods, such as high pressure (HP) processing, prolong shelf-life while assuring high food quality. The effect of HP processing (600MPa, 25 °C, 5min) on European sea bass (Dicentrarchus labra...
Temperature responsiveness of gilthead sea bream bone; an in vitro and in vivo ...
Riera-Heredia, Natalia; Martins, Rute; Patricia Mateus, Ana; Costa, Rita; Gisbert, Enric; Navarro, Isabel; Gutierrez, Joaquim; Power, Deborah M.This study aimed to characterize the molecules involved in osteogenesis in seabream and establish using in vitro/in vivo approaches the responsiveness of selected key genes to temperature. The impact of a temperature drop from 23 to 13 degrees C was evaluated in juvenile fish thermally imprinted during embryogenesis. Both, in vitro/in vivo, Fib1a, appeared important in the first stages of bone formation, and Co...
Persistence of the ABCC6 genes and the emergence of the bony skeleton in verteb...
Parreira, Bruna; Cardoso, João; Costa, Rita; Couto, Ana Rita; Bruges-Armas, Jacome; Power, Deborah M.The ATP-binding cassette transporter 6 (ABCC6) gene encodes a cellular transmembrane protein transporter (MRP6) that is involved in the regulation of tissue calcification in mammals. Mutations in ABCC6 are associated with human ectopic calcification disorders. To gain insight into its evolution and involvement in tissue calcification we conducted a comparative analysis of the ABCC6 gene and the related gene ABC...
Revealing higher than expected meiofaunal diversity in Antarctic sediments: a m...
Fonseca, V. G.; Sinniger, F.; Gaspar, J. M.; Quince, C.; Creer, S.; Power, Deborah M.; Peck, Lloyd S.; Clark, Melody S.An increasing number of studies are showing that Antarctic mega- and macrofauna are highly diverse, however, little is known about meiofaunal biodiversity in sediment communities, which are a vital part of a healthy and functional ecosystem. This is the first study to analyse community DNA (targeting meiofauna) using metabarcoding to investigate biodiversity levels in sediment communities of the Antarctic Penin...
Transcriptomics reveal an integrative role for maternal thyroid hormones during...
Silva, Nadia; Louro, Bruno; Trindade, Marlene; Power, Deborah M.; Campinho, Marco A.Thyroid hormones (THs) are essential for embryonic brain development but the genetic mechanisms involved in the action of maternal THs (MTHs) are still largely unknown. As the basis for understanding the underlying genetic mechanisms of MTHs regulation we used an established zebrafish monocarboxylic acid transporter 8 (MCT8) knock-down model and characterised the transcriptome in 25hpf zebrafish embryos. Subseq...
Phylogeny, expression patterns and regulation of DNA Methyltransferases in earl...
Firmino, Joana; Carballo, Carlos; Armesto, Paula; Campinho, Marco António; Power, Deborah M.; Manchado, ManuelBackground: The identification of DNA methyltransferases (Dnmt) expression patterns during development and their regulation is important to understand the epigenetic mechanisms that modulate larval plasticity in marine fish. In this study, dnmt1 and dnmt3 paralogs were identified in the flatfish Solea senegalensis and expression patterns in early developmental stages and juveniles were determined. Additionally,...
