1. 6. In vitro wound healing characteristics of amelogenins

   Författare :Sofia Almqvist; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amelogenins; extracellular matrix; cell culture; macrophage; fibroblast; endothelial cell; integrin; cytokine; inflammation; wound healing tissue repair;

   Sammanfattning : Wound healing involves the co-ordinated actions of several cell types, soluble cell mediators and extracellular matrix (ECM). This research project intended to investigate the role of certain ECM proteins in different processes during tissue repair by studying the interaction between dermal cells and ECM. LÄS MER

3. 7. Regulation of Vitamin D 25-hydroxylases : Effects of Vitamin D Metabolites and Pharmaceutical Compounds on the Bioactivation of Vitamin D

   Författare :Maria Ellfolk; Kjell Wikvall; Maria Norlin; Olavi Pelkonen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CYP2D25; vitamin D 25-hydroxylase; transcriptional regulation; vitamin D; CYP2R1; CYP2J2; CYP27A1; phenobarbital; efavirenz; fibroblast; LNCaP; Pharmaceutical biochemistry; Farmaceutisk biokemi;

   Sammanfattning : A 700bp portion of the promoter of CYP2D25, the porcine microsomal vitamin D 25-hydroxylase was isolated and sequenced. The computer analysis of the sequence revealed the existence of a putative VDRE at 220 bp upstream of the transcription start site. LÄS MER

4. 8. Controlled axonal outgrowth and cell reactions to nanostructures

   Författare :Fredrik Johansson; Funktionell zoologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Contact guidance; neuron; axon; fibroblast; macrophage; polymethylmethacrylate; porous silicon; nanowire; magnetic; immunoresponse; nanoimprint lithography; haptotaxis;

   Sammanfattning : The interface between living cells and artificial surfaces are highly relevant for biomedical applications such as implants and organized cell growth for tissue reconstruction as well as for basic science purposes. In the present thesis, we have studied axonal guidance on various nano-patterned surfaces such as polymethyl-meth-acrylate, porous silicon and on magnetically aligned Ni nanowires. LÄS MER

5. 9. Collagen-binding integrin α2β1 activity in vivo and in vitro : Effects of platelet-derived growth factor-BB

   Författare :Karina Åhlén; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Integrin α2β1; PDGF-BB; fibroblast; interstitial fluid pressure; cytoskeletal interaction; phosphatidylinositol 3-kinase; [Ca2 ]i; Biokemi; Biochemistry; Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

   Sammanfattning : The expression of integrins by two cell clones from a rat colon carcinoma was investigated. Cloned cells that gave rise to regressive tumors, but not cells that gave rise to progressive, lethal, tumors, adhered to interstitial collagens through the integrin α2β1, although both cell types expressed it.

7. 10. Fibroblast growth factor-23 and Klotho in bone/mineral and parathyroid disorders

   Författare :Tijana Krajisnik; Tobias E. Larsson; Kenneth B. Jonsson; Östen Ljunggren; Peyman Björklund; Gunnar Sterner; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; calcitriol; chronic kidney disease; CKD; chronic renal failure; fibroblast growth factor 23; fibroblast growth factor-23; FGF23; FGF-23; GalNac-T3; GALNT3; GFR; hyperostosis-hyperphosphatemia syndrome; HHS; Klotho; parathyroid hormone; PTH; hyperparathyroidism; pHPT; sHPT; uremic; vitamin D3; Endocrinology; Endokrinologi; Internal Medicine; invärtesmedicin;

   Sammanfattning : Fibroblast growth factor-23 (FGF23) is a novel, bone-produced hormone that regulates renal phosphate (Pi) reabsorption and calcitriol metabolism. Disorders of mineral and bone metabolism, such as autosomal dominant hypophosphatemic rickets (ADHR) and hyperostosis-hyperphosphatemia syndrome (HHS), witness the importance of well-balanced serum levels of FGF23.
