  1. 1. Water transport through perinatal skin : Barrier function and aquaporin water channels

    Författare :Johan Ågren; Gunnar Sedin; Gunnar Flemström; Steven B Hoath; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Preterm infant; Transepidermal water loss; Aquaporin; Skin biology; Hyperosmolarity; Pediatrik; Paediatric medicine; Pediatrisk medicin; pediatrik; Pediatrics;

    Sammanfattning : While constituting a well functioning interface with the aqueous environment in utero, the skin offers a poor barrier after very preterm birth. As a result, transepidermal water loss (TEWL) is high, a fact which has important clinical consequences in these infants. LÄS MER

  3. 2. Regulation of glycerol efflux in adipocytes. Structural and functional studies of the glycerol channel aquaporin 7

    Författare :Sofia de Mare; Medicinsk strukturbiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glycerol : metabolism; Lipolysis; X-ray Crystallography; Perilipin 1; Aquaglyceroporin; Aquaporin 7; Adipocytes metabolism; Glycerol : metabolism; adipocyte metabolism; X-ray crystallography; Aquaglyceroporin; Aquaporin 7; Perilipin 1; Lipolysis;

    Sammanfattning : Glycerol levels in adipocytes depend on the lipolysis, the hydrolysis of triglycerides into glycerol and free fatty acids, and the efflux of glycerol across the plasma membrane through glycerol channels. The aims of this work were to investigate how glycerol levels are regulated on a molecular level by PLIN1, a major lipid droplet-associated protein and a key regulator of the lipolysis by scaffolding for lipolytic proteins on the lipid droplet.

  4. 3. Expression and Function of Human and Plant Aquaporins

    Författare :Maria Agemark; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aquaporin; water channel; overexpression; Pichia pastoris; AQP8; AQP5; SoPIP2; 1;

    Sammanfattning : The aquaporins (AQPs) belong to a family of water permeable membrane channels found in virtually all living organisms. Thirteen isoforms of mammalian AQPs are found, whereas in Arabidopsis thaliana 35 genes encoding AQPs are found. The AQPs are distributed in different organs, cell types and in different subcellular membranes. LÄS MER

  5. 4. Plant Major Intrinsic Proteins - natural variation and evolution

    Författare :Jonas Danielson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MIP; aquaporin; plant; natural variation; evolution; Arabidopsis; Physcomitrella patens; NIP; XIP;

    Sammanfattning : Major Intrinsic Proteins (MIPs, also called Aquaporins, AQPs) are channel forming membrane proteins. Although initially functionally characterized and named after their water channeling property in human red blood cells, it has become increasingly evident that MIPs are present in all types of organisms and transport a variety of small, uncharged molecules besides water.

  7. 5. Aquaporin homologues in Norway spruce (Picea abies)

    Författare :Peter Oliviusson; David I. Dunstan; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi; växtfysiologi; Plant Physiology;

    Sammanfattning : The recent discovery of aquaporins - proteins that mediate bidirectional passage of water over membranes - provides a molecular basis for the underlying processes in plant water relations. In plants, aquaporins are found in plasma membranes and in vacuolar membranes (tonoplasts) and are suggested to participate in dynamic operations such as cell elongation, osmotic regulation, and long-distance transport.
