  1. 1. Wnt/β-Catenin Signalling in Parathyroid Tumours

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Peyman Björklund; Gunnar Westin; Göran Åkerström; Tommy Andersson; [2007]
    Keywords : Surgery; Hyperparathyroidism; β-catenin; Mutation; Human parathyroid cell line; LRP5; Alternative splicing; Kirurgi;

    Abstract : Primary hyperparathyroidism (pHPT) due to parathyroid tumours with hypersecretion of parathyroid hormone and hypercalcaemia is a common disease with incompletely understood etiology affecting more than 1 % of the population, primarily postmenopausal women. In secondary hyperparathyroidism (sHPT), parathyroid tumours develop in response to calcium and vitamin D deficiency generally in patients with uraemia. READ MORE

  2. 2. Regulation of morphogen signalling during neural patterning in the Xenopus embryo

    University dissertation from Department of Laboratory Medicine, Lund University

    Author : Hooi Min Tan Grahn; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Suppressor-of-fused; Gli; β-Catenin; Neural; Xenopus; FGF; Signalling; HtrA1; RDH10; Retinol dehydrogenase; Retinoic acid; Spemann s organizer; Induction; Gradient;

    Abstract : Morphogens such as Hedghog, Wnt, FGF, and retinoic acid are important signals whose concentrations need to be tightly regulated in the vertebrate embryo to ensure body axis development and formation of the central nervous system. We first show that the intracellular cytoplasmic protein XSufu acts as a dual regulator of Hedgehog (Hh) and Wnt signals during neural induction and patterning in the Xenopus embryo. READ MORE

  3. 3. Role of ß-catenin and Leukotriene in Colon Cancer Progression

    University dissertation from Cell Pathology

    Author : Tavga Salim; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LTD4; β-catenin; E-cadherin; GSK-3β; inflammation; colorectal cancer;

    Abstract : Abstract Colorectal cancer is the third most common cancer worldwide. Deregulation of Wnt/β-catenin signalling pathway is an early hallmark of colon cancer. Were nuclear accumulation of β-catenin is a marker of activated canonical Wnt/β-catenin signaling. One of the risk factors for development of colon cancer is inflammatory bowel disease. READ MORE

  4. 4. Cellular pathways and molecular regulation of hematopoietic stem cells

    University dissertation from Hematopoietic Stem Cell Laboratory

    Author : Kristina Anderson; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; β-catenin.; lineage commitment; hematopoietic stem cells; lineage priming; Wnt signaling pathway; biphenotypic cells; PAX5;

    Abstract : Hematopoietic stem cells (HSCs) are defined by their unique properties to self-renew and differentiate into all hematopoietic cell lineages. Residing in the bone marrow (BM), adult HSCs are organized in a hierarchy of cells that differ in their self-renewal and proliferative capacity. READ MORE

  5. 5. Studies on the biological functions of interaction between components in Wnt, TGF-β and HIF pathways for cancer progression

    University dissertation from Hematopoietic Stem Cell Laboratory

    Author : Karthik Aripaka; Maréne Landström; Jonas von Hofsten; Carl-Henrik Heldin; Ruth Palmer; Lars-Gunnar Larsson; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TRAF6; HIF-1α; HIF-2α; HIF-3α; ALK5; Wnt3a; Hypoxic signalling; TGF-β; zebrafish; β-Catenin; Pathology; patologi; Oncology; onkologi;

    Abstract : Cancer is a disease that involves aggressive changes in the genome and aberrant signals between the living cells. Signalling pathways such as TGF-β (Transforming growth factor-β), Wnt, EGF (epidermal growth factor) and HIF (Hypoxia-inducible factor) evolved to regulate growth and development in mammals. READ MORE
