Differential tissue immune stimulation through immersion in bacterial and viral...
Sousa, Carmen; Peng, Maoxiao; Guerreiro, Pedro; Cardoso, João; Chen, Liangbiao; Canario, Adelino; Power, DeborahThe genome evolution of Antarctic notothenioids has been modulated by their extreme environment over millennia and more recently by human -caused constraints such as overfishing and climate change. Here we investigated the characteristics of the immune system in Notothenia rossii and how it responds to 8 h immersion in viral (Poly I:C, polyinosinic: polycytidylic acid) and bacterial (LPS, lipopolysaccharide) pr...
The physiological effect of polystyrene nanoplastic particles on fish and human...
Peng, Maoxiao; Félix, Rute C.; Canario, Adelino; Power, DeborahNumerous studies have identified the detrimental effects for the biosphere of large plastic debris, the effect of microplastics (MPs) and nanoplastics (NPs) is less clear. The skin is the first point of contact with NPs, and skin fibroblasts have a vital role in maintaining skin structure and function. Here, a comparative approach is taken using three fibroblast cell lines from the zebrafish (SJD.1), human male...
Ioxynil and diethylstilbestrol impair cardiac performance and shell growth in t...
Li, Yi-Feng; Lin, Yue-Tong; Wang, Yu-Qing; Ni, Ji-Yue; Power, DeborahThe herbicide ioxynil (IOX) and the synthetic estrogen diethylstilbestrol (DES) are environmentally relevant contaminants that act as endocrine disruptors (EDCs) and have recently been shown to be cardiovascular disruptors in vertebrates. Mussels, Mytilus coruscus, were exposed to low doses of IOX (0.37, 0.037 and 0.0037 mg/ L) and DES (0.27, 0.027 and 0.0027 mg/L) via the water and the effect monitored by gene...
Gene transcripts responsive to drought stress identified in Citrus macrophylla ...
da Silva, Melina; Pinto, Patricia IS; Guerra, Rui Manuel Farinha das Neves; Duarte, Amilcar; Power, Deborah; Marques, N T.Citrus macrophylla Wester (CM) has valuable agronomic characteristics such as the ability to grow in saline soils, although with low tolerance to prolonged drought stress (DS). To understand the mechanisms that characterize CM response to water scarcity, this study compared transcriptome profile changes in CM stem tissue when exposed to DS and identified a total of 2745 differentially expressed transcripts (DET...
Stage-specific transcriptomes of the Mussel Mytilus coruscus reveals the develo...
Wang, Yu-Qing; Liu, Qi; Zhou, Yan; Chen, Lizhi; Yang, Yue-Ming; Shi, Xue; Power, Deborah; Li, Yi-FengMany marine invertebrate larvae undergo complex morphological and physiological changes during the planktonic—benthic transition (a.k.a. metamorphosis). In this study, transcriptome analysis of different developmental stages was used to uncover the molecular mechanisms underpinning larval settlement and metamorphosis of the mussel, <i>Mytilus coruscus</i>. Analysis of highly upregulated differentially expressed...
Thermal imprinting during embryogenesis modifies skin repair in juvenile Europe...
Mateus, Ana; Costa, Rita; Sadoul, Bastien; Bégout, Marie-Laure; Cousin, Xavier; Canario, Adelino; Power, DeborahFish skin is a multifunctional tissue that develops during embryogenesis, a developmental stage highly suscep-tible to epigenetic marks. In this study, the impact of egg incubation temperature on the regeneration of a cutaneous wound caused by scale removal in juvenile European sea bass was evaluated. Sea bass eggs were incubated at 11, 13.5 and 16 degrees C until hatching and then were reared at a common tempe...
Core microbiome profiles and their modification by environmental, biological, a...
Najafpour, Babak; Pinto, Patricia IS; Sanz, Eric Climent; Martinez-Blanch, Juan F.; Canario, Adelino; Moutou, Katerina A.; Power, Deborah16S rRNA gene sequencing and bacteria-and genus-specific quantitative PCR was used to profile microbial communities and their associated functions in water, live feed (microalgae, Artemia, and rotifer), and European sea bass and gilthead sea bream larvae from hatcheries in Greece and Italy. The transfer to larvae of genus containing potential pathogens of fish was more likely with Artemia and rotifer than with ...
The impact of egg thermal regimes on the response to food deprivation and refee...
Mateus, Ana; Costa, Rita; Jiménez, Javier; Sadoul, Bastien; Bégout, Marie Laure; Cousin, Xavier; Canario, Adelino; Power, DeborahFish are ectotherms and this means they are highly vulnerable to changes in ambient temperature, particularly during early developmental stages when temperature can induce persistent effects on phenotypic traits. In this study, the effect of egg incubation temperature on the response of juvenile European sea bass (Dicentrarchus labrax) to food deprivation and recovery after refeeding was assessed. Eggs were inc...
Quick decline and stem pitting Citrus tristeza virus isolates induce a distinct...
Dandlen, Susana; Da Silva, José Paulo; Miguel, Maria Graca; Duarte, Amilcar; Power, Deborah; Marques, NatáliaSusceptibility to the severe Citrus tristeza virus (CTV), T36, is higher for Citrus macrophylla (CM) than for C. aurantium (CA). How host-virus interactions are reflected in host physiology is largely unknown. In this study, the profile of metabolites and the antioxidant activity in the phloem sap of healthy and infected CA and CM plants were evaluated. The phloem sap of quick decline (T36) and stem pitting (T3...
Exosome delivery to the testes for dmrt1 suppression: a powerful tool for sex-d...
Zhu, Tengfei; Kong, Ming; Yu, Yingying; Schartl, Manfred; Power, Deborah; Li, Chen; Ma, Wenxiu; Sun, Yanxu; Li, Shuo; Yue, Bowen; Li, WeijingExosomes are endosome-derived extracellular vesicles about 100 nm in diameter. They are emerging as prom ising delivery platforms due to their advantages in biocompatibility and engineerability. However, research into and applications for engineered exosomes are still limited to a few areas of medicine in mammals. Here, we expanded the scope of their applications to sex-determining gene studies in early vertebr...
