  1. 21. Functional studies of the Quaking gene : Focus on astroglia and neurodevelopment

    Författare :Katarzyna Radomska; Elena Jazin; Pertti Panula; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; QKI; RNA-binding protein; astrocyte; interferon; GFAP; neurodevelopment; zebrafish; neural progenitor cell;

    Sammanfattning : The RNA-binding protein Quaking (QKI) plays a fundamental role in post-transcriptional gene regulation during mammalian nervous system development. QKI is well known for advancing oligodendroglia differentiation and myelination, however, its functions in astrocytes and embryonic central nervous system (CNS) development remain poorly understood.

  3. 22. On oxytocin and social behavior

    Författare :Daniel Hovey; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oxytocin; social cognition; autism; antisocial behavior; zebrafish;

    Sammanfattning : Complex social cognitive processes underlie social behavior. Oxytocin has long been recognized as crucial in social behavior in animals, but its role in regulating human social cognition and behavior is less clear, particularly with regard to endogenous oxytocin. LÄS MER

  4. 23. Effects of mixtures of endocrine disrupting chemicals – Thyroid disruption and behavioural effects in fish models

    Författare :Lina Birgersson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; endocrine disrupting chemicals; ecotoxicology; zebrafish; perch; locomotion; behaviour; thyroid disruption; EDC mixtures;

    Sammanfattning : Wildlife and humans are continuously exposed to thousands of man-made compounds, including chemicals that are able to act as endocrine disruptors (EDCs). These pollutants are able to affect vital processes including brain development, reproduction, metabolism and growth. LÄS MER

  5. 24. Characterization and environmental influences on inflammatory and physiological responses

    Författare :Hazem Khalaf; Per-Erik Olsson; Joe de Pierre; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inflammation; NF-κB; cytokines; pharmaceuticals; zebrafish; Biology; Biologi; NATURAL SCIENCES; NATURVETENSKAP; Biology; Biologi;

    Sammanfattning : Pharmaceuticals are regularly released into the environment, in particular nonsteroidalanti-inflammatory drugs (NSAIDs) and antibiotics. The measuredconcentrations are relatively low and have therefore been considered to be harmless. LÄS MER

  7. 25. Cloning and characterization of neuropeptide Y receptors of the Y1 subfamily in mammals and fish

    Författare :Paula Starbäck; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; G-protein; neuropeptide Y; panacreatic polypeptide; neuropeptide Y receptor; ortholog; zebrafish; guinea pig; pseudogene; evolution; Neurovetenskap; Neurology; Neurologi; Neurology; neurologi;

    Sammanfattning : Neuropeptide Y (NPY) is an abundant neurotransmitter in the nervous system and forms a family of evolutionarily related peptides together with peptide YY (PYY), pancreatic polypeptide (PP) and polypeptide Y (PY). These peptides are ligands to a family of receptors that mediate a wide range of physiological effects including stimulation of appetite. LÄS MER
