1. 21. Stimulus-Section Coupling in Endocrine Cell Models

   Författare :Lotta Andersson; Diabetes - molekylär metabolism; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Detailed understanding of biological systems governing specific mechanisms and pathways is essential in the development of novel disease therapies. Stimulus-secretion coupling in hormone secreting cells is a complex system of pathways that link activation of cellular processes by i.e. nutrients to the release of hormone. LÄS MER

3. 22. Cell cycle regulation in cancer: A noncoding perspective

   Författare :Mohamad Ali; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long Noncoding RNA; lncRNA; Cell cycle; S phase; Mitosis; Checkpoint; Cancer; SCAT7; LY6K-AS;

   Sammanfattning : The cell cycle progression is tightly regulated to ensure error-free cell replication. The complexity of the transcriptional machinery aids to function in a spatiotemporal pattern across different phases and genomic loci. LÄS MER

4. 23. Models of Retinal Development and Disease

   Författare :Minas Hellsand; Finn Hallböök; Emma Andersson; Department of Cell and Molecular Biology Karolinska Institutet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Developmental neurobiology; retinal organoids; retinoblastoma; MYCN; Stargardt disease; Bardet-Biedl syndrome; model systems;

   Sammanfattning : For a model of a human disease to be valid and useful, it is important that key genotypic and phenotypic traits are shared between model system and human. The work in this thesis has been focused on generating new and characterizing spontaneous models of three genetic disorders affecting the retina: retinoblastoma, a childhood cancer with its origin in the fetal retina, Stargardt disease, a juvenile form of macular degeneration, and Bardet-Biedl syndrome, a pleiotropic ciliopathy featuring retinal degeneration.

5. 24. Cell fate specification by Ras-mediated cell signalling in C. elegans

   Författare :Teresa Tiensuu; Simon Tuck; Benjamin Podbilewicz; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; cell signalling; Ras; vulva precursor cell; lin-25; sur-2; lin-1; cell fate specification; Mediator; vulva induction; transcriptional regulation; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

   Sammanfattning : Induction of vulval fates in the C. elegans hermaphrodite is mediated by a conserved RTK/Ras/MAP kinase signalling pathway, in which the core components can be placed into a linear genetic and biochemical pathway. However, the events that occur downstream of this pathway are not yet well understood. LÄS MER

7. 25. Macrophage-material surface interactions

   Författare :Christina Gretzer; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Apoptosis; biomaterials; cell-cell interactions; cell-material interactions; cytokines; differentiation; fibrinogen; hydrogen peroxide; LPS; monocytes; particles;

   Sammanfattning : Material surface-stimulated activation of the macrophage and the release of mediators has been suggested to be an important factor for inflammation and tissue regeneration around biomedical implants. Macrophage interactions with particles released from implants as well as macophage-bacteria interactions are also involved in implant loosening processes. LÄS MER
