    Sammanfattning : Many cyanobacteria are reported to produce the nonprotein amino acid β-N-methylamino-L-alanine (BMAA). Cyanobacteria are extensively distributed in terrestrial and aquatic environments and recently BMAA was detected in temperate aquatic ecosystems, e.g. the Baltic Sea. LÄS MER

    Sammanfattning : Brain development is a highly orchestrated process that entails changes in microenvironmental cues and growth factor gradients, which set the tempo for proper development of the rudimentary structures of the brain and the generation of neurons,astrocytes, and oligodendrocytes. Another intricate feature of the brain is the bloodbrain barrier (BBB). LÄS MER

  4. 3. Wnt-5a Signalling in Human Mammary Cells: Implications for the Development of Breast Cancer

    Författare :Marzieh Jönsson; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; Cytology; signalling; breast cancer; Wnt-5a; mammary epithelial cells; cancer; onkologi; Cytologi; cancerology;

    Sammanfattning : The Wnt-5a gene encodes a secreted protein that regulates several normal processes in embryonic and adult tissues by as yet unknown mechanisms. Expression of Wnt-5a protein does not cause cell transformation, but it instead counteracts the effects induced by transforming Wnts. LÄS MER
