  2. 1. 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.

  4. 2. Molecular and functional studies of interleukin-1a in the rat testis

    Author : Taranum Sultana; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Interleukin-l alpha; spermatogenesis; Leydig cells; Sertoli cells; calpain I and II;

    Abstract : The aim of the present study was to gain a better insight into the role of interleukin-1 alpha (IL-1 alpha) in testicular physiology. In testis, IL-1alpha acts as a paracrine mediator involved in the regulation of testicular functions. READ MORE

  6. 4. Testicular blood flow : methodological and functional studies in the rat

    Author : Jan-Erik Damber; Umeå universitet; []
    Keywords : ;

    Abstract : Different methods of measuring testicular blood flow in the rat were compared in an attempt to find an accurate method for measuring physiological testicular blood flow. It was found that both the Xenon- 133 clearance technique and the radioactive microsphere technique probably reflect true physiological blood flow in the testis. READ MORE

  7. 5. Antimicrobial and xenobiotic defence in the mammalian testis

    Author : Mona-Lisa Strand; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Different mechanisms exist in the mammalian testis to protect the germ cells from autoimmune attack, invading microbes, and xenobiotic induced toxicity, which would otherwise be deleterious to the preservation of fertility. The general aim of this thesis was to study these testicular defence mechanisms, including the structural building blocks of the blood– testis barrier (BTB), antimicrobial peptides, proinflammatory cytokines and ATP-binding cassette (ABC) transporter proteins.
