  1. 11. Protein Damage Control during Embryonic Stem Cell Differentiation: Role of the Proteasome

    Författare :Malin Hernebring; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Embryonic Stem Cells; Proteasome; Protein Carbonylation; Advanced Glycation End products; Cell Differentiation; Oxidative stress; Aging; RNAi;

    Sammanfattning : During the lifespan of organisms ranging from yeast to humans, there is an accumulation of macromolecular damage. However, these organisms produce youthful progeny with low damage levels. This thesis focuses on how this is accomplished. LÄS MER

  3. 12. Notch signalling in carcinogenesis : With special emphasis on T-cell lymphoma and colorectal cancer

    Författare :Jonas Ungerbäck; Peter Söderkvist; Ola Hermanson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Notch signalling; T-cell lymphoma; colorectal cancer; Wnt signalling; transcription; Medical cell biology; Medicinsk cellbiologi;

    Sammanfattning : The Notch signalling pathway is an evolutionary conserved pathway, named after the Notch receptors, Notch1-4 in mammals, which upon cell-cell contact and ligand binding releases the intracellular domain (NICD). NICD translocates into the nucleus where it binds the transcriptional repressor RBP-Jk, which together with co-activators belonging to the Mastermind-like family of proteins form a transcriptional activation complex.

  4. 13. Modelling Human Developmental Hematopoiesis. Towards in vitro Generation of Human Hematopoietic Stem Cells

    Författare :Carolina Guibentif; Avdelningen för molekylärmedicin och genterapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Human pluripotent stem cells; Embryonic Development; endothelial-to-hematopoietic transition; Hematopoiesis;

    Sammanfattning : The possibility to manufacture hematopoietic stem cells (HSCs) in the laboratory would provide an indefinite source of cells for patients requiring bone marrow transplantation. Moreover, combined with the progress in gene editing techniques, it would provide a novel platform for gene and cell replacement therapies for a range of currently incurable congenic and acquired disorders.

  5. 14. Human Embryonic Stem Cells - Constitutive Gene Expression and Differentiation Towards Definitive Endoderm and Posterior Foregut Endoderm

    Författare :Karin Norrman; Stamcellscentrum (SCC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human embryonic stem cells; diabetes; pancreas; definitive endoderm; foregut endoderm; pancreatic endoderm; constitutive promoter; ACTB; EF1alpha; CMV; PGK; UbC;

    Sammanfattning : Abstract More than 300 million people are suffering from diabetes worldwide and the numbers of diabetic patients are increasing. Today´s treatments mainly rely on daily insulin injections. This help people to control blood glucose levels but still many patients suffer from the many complications associated with diabetes.

  7. 15. Pluripotent Stem Cells of Embryonic Origin : Applications in Developmental Toxicology

    Författare :Måns Jergil; Lennart Dencker; Aldert Piersma; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Embryonic stem cell; Microarray; Toxicogenomics; Valproic acid; Developmental toxicology; Teratogenicity; Neural tube defects; Histone deacetylase inhibitor; In vitro toxicology; Toxicology; Toxikologi; Toxicology; Toxikologi;

    Sammanfattning : General toxicity evaluation and risk assessment for human exposure is essential when developing new pharmaceuticals and chemicals. Developmental toxicology is an important part of this risk assessment which consumes large resources and many laboratory animals. LÄS MER
