  1. 1. Studies of neuropeptides in pancreatic beta cell function with special emphasis on islet amyloid polypeptide (IAPP)

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ella Karlsson; Uppsala universitet.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; alpha cell; amylin; beta cell; chromogranin; growth; IAPP; insulin; islet amyloid polypeptide; leptin; NOD mice; pancreastatin; pancreatic islet; proliferation; Cellbiologi; MEDICINE Morphology; cell biology; pathology Cell biology; MEDICIN Morfologi; cellbiologi; patologi Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : The presence of protein amyloid in pancreas and its association to diabetes was first described 100 years ago in 1901, but was not identified as Islet Amyloid Polypeptide (IAPP) until 1986. The aim of the present work was to determine the role of the beta cell hormone, IAPP, in normal pancreatic islet physiology and during early disturbances of islet function. READ MORE

  2. 2. TGF-beta signaling in cancer

    University dissertation from Göteborg : Intellecta Infolog AB

    Author : Erik Johansson; Göteborgs universitet.; Gothenburg University.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TGF-β; proliferation; cancer; tumor suppressor; diffuse-type gastric carcinoma; neuroblastoma; nuclear receptor TLX; cancer stem cell; angiogenesis; ABCG2; VHL; HIF2α; hypoxia; Smad3;

    Abstract : Transforming Growth Factor Beta (TGF-β) is a cytokine regulating a wide range of cellular processes such as proliferation, differentiation, and migration. At the early stages of cancer development TGF-β functions as a tumor suppressor, mainly due to its inhibitory effect on cellular growth, but during cancer progression, mutations in TGF-β signal components switches TGF-β into a promoter of cancer cell proliferation, survival and metastasis.

  3. 3. Genetic pathways controlling CNS development The role of Notch signaling in regulating daughter cell proliferation in Drosophila

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Caroline Bivik Stadler; Linköpings universitet.; Linköpings universitet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The human central nervous system (CNS) displays the greatest cellular diversity of any organ system, consisting of billions of neurons, of numerous cell sub-types, interconnected in a vast network. Given this enormous complexity, decoding the genetic programs controlling the multistep process of CNS development remains a major challenge. READ MORE

  4. 4. Genetic mechanisms regulating proliferation and cell specification in the Drosophila embryonic CNS

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Shahrzad Bahrampour; Linköpings universitet.; Linköpings universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The central nervous system (CNS) consists of an enormous number of cells, and large cellular variance, integrated into an elaborate network. The CNS is the most complex animal organ, and therefore its establishment must be controlled by many different genetic programs. READ MORE

  5. 5. Invasion and Proliferation in Malignant Cells

    University dissertation from Department of Laboratory Medicine, Lund University
