  1. 1. Growth factors in spermatogenesis

    Author : Aida Wahlgren; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Testis; seminiferous tubules; proliferation; growth factors; sex steroids;

    Abstract : The aim of this study was to increase the knowledge of die effects of locally produced growth factors and hormones on germ cell proliferation in rat testis in vitro. Since impaired sperm production and function accounts for half the cases of infertility, it is important to understand the physiological actions in germ cell development. READ MORE

  2. 2. Mitochondrial Iron Metabolism : Study of mitoferrin in Drosophila melanogaster

    Author : Christoph Metzendorf; Maria Lind Karlberg; Kenneth Söderhäll; Martina Muckenthaler; Uppsala universitet; []

    Abstract : Iron has a dualistic character. On the one hand it is essential for the life of most organisms, on the other hand it is involved in the generation of reactive oxygen species that are implicated in diseases and aging. READ MORE

  4. 4. Hormone-Sensitive Lipase and Protein Kinase B; Molecular characterization in testis, adipose tissue and pancreatic beta cells

    Author : Lena Stenson; Signaltransduktionsforskning; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; signal transduction; pancreas; beta cells; adipocyte; insulin; Akt; protein kinase B; spermatogenesis; cholesterol esterase; hormone-sensitive lipase; testis; cAMP; Proteins; enzymology; Proteiner; enzymologi;

    Abstract : Hormone-sensitive lipase (HSL) and protein kinase B (PKB) are enzymes that in different ways are associated with lipid metabolism. While HSL is the well-known lipolytic enzyme responsible for hydrolysis of stored triacylglycerols in adipose tissue, PKB is a recently identified serine/threonine protein kinase, ubiquitously expressed and involved in signal transduction pathways induced by insulin and growth factors.
