  4. 2. Regulation of Angiogenesis

    Author : Helena Larsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; angiogenesis; anti-angiogenesis; endostatin; latent antithrombin; prelatent antithrombin; Crk; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

    Abstract : Angiogenesis is the formation of new blood vessels from pre-existing ones. New blood vessel formation is fundamental in processes such as reproduction, embryonic development and wound healing. Growth of neoplasms is accompanied by increased angiogenesis. This thesis describes cellular and molecular mechanisms of importance for angiogenesis. READ MORE

  5. 3. Negative regulation of growth hormone (GH) signaling

    Author : Elizabeth Rico Bautista; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Growth Hormone (GH) regulates postnatal longitudinal growth. It also has several other functions. It decreases cholesterol and lipoproteins levels, reduces fat tissue and increases lean body mass. GH actions are mediated by the JAK2/STAT5 signaling pathway. READ MORE
