  1. 1. New insights of LXR signalling in inhibition of cancer proliferation and inflammation

    Author : Treska Hassan; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : Liver X receptors (LXRs) are ligand-activated transcription factors belonging to the nuclear receptor (NR) superfamily. Up-to-date, more than 1900 publications have established the role of LXRs in cholesterol homeostasis, lipogenesis, glucose metabolism, atherosclerosis, proliferation, and inflammation. READ MORE

  2. 2. Behaviour under predation risk in birds

    Author : Cecilia Kullberg; Neil B Metcalfe; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Animal physiology; Zoofysiologi;

    Abstract : Predation is a major selective force in the evolution of both morphological and behavioural characters in animals. The flexibility in behavioural traits according to perceived predation risk has received much attention in recent years. READ MORE

  3. 3. Contribution of polyfluoroalkyl phosphate esters (PAPs) and other precursor compounds to perfluoroalkyl carboxylates (PFCAs) in humans and the environment

    Author : Ulrika Eriksson; Anna Kärrman; Bert van Bavel; Gunilla Lindström; Jonathan Martin; Örebro universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; PAPs; precursors; PFCA; exposure; indoor dust; human serum; WWTP; bird eggs; Kemi; Chemistry;

    Abstract : Per-and polyfluoroalkyl substances (PFAS) are anthropogenic compounds that have been spread all over the world. The use of fluorotelomer compounds, short-chained homologues, and other PFASs with perfluorinated moieties has emerged recent years. READ MORE

  4. 4. Conservation Genetics of the White-Tailed Eagle

    Author : Frank Hailer; Hans Ellegren; Carles Vilà; Rob C Fleischer; Uppsala universitet; []
    Keywords : Biology; Haliaeetus albicilla; microsatellites; mtDNA; molecular sexing; population structure; bottleneck; phylogeography; raptors; Biologi;

    Abstract : The white-tailed eagle is a formerly threatened raptor that is commonly used as a flagship and indicator species in conservation work. This thesis uses molecular genetic methods to study sex determination of nestlings, genetic variability, population structure and phylogeography of the white-tailed eagle. READ MORE

  5. 5. Cross-regulation between TGFβ/BMP Signalling and the metabolic LKB1 pathway

    Author : Erna Raja; Aristidis Moustakas; Tomi Mäkelä; Uppsala University Faculty of Medicine Ludwig Institute for Cancer Research; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; cell signalling; TGFbeta; BMP; LKB1; AMPK; Molekylär cellbiologi; Molecular Cellbiology;

    Abstract : Cell signalling determines physiological responses to many cellular stimuli and environmental changes. The transforming growth factor-beta (TGFβ)/bone morphogenetic protein (BMP) signalling pathways begin by binding of ligand to the heterodimeric receptor complex, followed by activation of Smads that translocate to the nucleus to regulate transcription of genes that further mediate cellular physiology.
