Some parasites are expected to have beneficial impacts on wild populations in polluted environments because of their bioaccumulation potential pollutants from hosts. The fate organic micropollutants host–parasite systems and the combined effect parasitism pollution were investigated chub Squalius cephalus, a freshwater fish, infected (n = 73) or uninfected 45) by acanthocephalan Pomphorhynchus sp. differently contaminated riverine sites. Several ubiquitous (polychlorinated biphenyls (PCBs),...
Abstract Droughts are becoming more intense and frequent with climate change. These extreme weather events can lead to mass mortality reproduction failure, therefore cause population declines. Understanding how the reproductive physiology of organisms is affected by water shortages will help clarify whether females adjust their strategy dry conditions or may fail reproduce survive. In this study, we investigated consequences a short period deprivation (2 weeks) during early pregnancy on...
Plasma phospholipid transfer protein (PLTP) is involved in intravascular lipoprotein metabolism. PLTP known to act through 2 main mechanisms: by remodeling high-density lipoproteins (HDL) and increasing apolipoprotein (apo) B-containing lipoproteins. The aim of this study was generate a new model human transgenic (HuPLTPTg) rabbit determine whether expression modulates atherosclerosis species that, unlike humans mice, displays naturally very low activity.In HuPLTPTg rabbits, the cDNA placed...
Some parasites are known to bioaccumulate some environmental pollutants within their host. We hypothesized that these may be beneficial for hosts in polluted environments. experimentally increased long-term (five weeks) exposure polycyclic aromatic hydrocarbons (PAHs, three levels: 0.1X, 1X, 10X exposure) European chubs (Squalius cephalus) were naturally infected or uninfected with acanthocephalan parasites. monitored PAHs levels fish tissues, as well oxidative stress, telomere length and...
Heatwaves and droughts are becoming more intense frequent with climate change. These extreme weather events often occur simultaneously may alter organismal physiology, yet their combined impacts remain largely unknown. Here, we experimentally investigated physiological responses of a temperate ectotherm, the asp viper (Vipera aspis), to simulated heatwave drought. We applied two-by-two factorial design by manipulating daily temperature cycle (control versus heatwave) water availability...
Male lizards often display multiple pigment-based and structural colour signals which may reflect various quality traits (e.g. performance, parasitism), with testosterone (T) mediating these relationships. Furthermore, environmental conditions can explain signal variation by affecting processes such as efficacy, thermoregulation camouflage. The relationships between signals, male factors have been analysed in isolation, but simultaneous analyses are rare. Thus, the response of to all an...
ABSTRACT One of the greatest current threats to biodiversity is climate change. However, understanding organismal responses fluctuations in temperature and water availability currently lacking, especially during fundamental life-history stages such as reproduction. To further explore how impact maternal physiology reproductive output, we used viviparous form European common lizard (Zootoca vivipara) a two-by-two factorial design manipulating both hydric thermal conditions, for first time. We...
Transmissible spongiform encephalopathies (TSEs) are a group of neurodegenerative diseases affecting wide range mammalian species. They caused by prions, proteinaceous pathogen essentially composed PrPSc, an abnormal isoform the host encoded cellular prion protein PrPC. Constrained steric interactions between PrPSc and PrPC thought to provide prions with species specificity, control cross-species transmission into other populations, including humans. Transgenetic expression foreign PrP genes...
Colour change is involved in various functions ranging from thermo- and hydroregulation to camouflage communication. The role of colour communication has received increased attention over the past few decades, yet been studied predominantly context intrasexual competition. Here, we investigate mate choice an animal that can its colour, panther chameleon (Furcifer pardalis). We conducted behavioural experiments analysis whether changes, including UV range, are choice. This study presents...
Gene constructs containing the Cauliflower mosaic virus (CaMV) 35S promoter and a sequence coding either for green fluorescent protein (GFP) or firefly luciferase were transfected into Chinese hamster ovary (CHO) cells. Both reporter genes expressed to significant levels. The was 40 times less active than human eF1 alpha promoter, which is known be one of most potent promoters in mammalian must therefore considered potency RT-PCR analysis suggested that transcription initiation CHO cells...
In eukaryotic cells, the organization of genomic DNA into chromatin regulates many biological processes, from control gene expression to regulation chromosome segregation. The proper maintenance this structure upon cell division is therefore prime importance during development for identity and genome stability. assembly factor 1 (CAF-1) involved in H3-H4 histone dimers on newly synthesized a higher order structure, heterochromatin, through an interaction its large subunit with...
