1. 1. TRAF6, a key regulator of TGFβ-induced oncogenesis in prostate cancer

   Författare :Reshma Sundar; Marene Landström; Carl-Henrik Heldin; Petra Knaus; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TβRI; TGFβ; TACE; TRAF6; PS1; PKCζ; TβRI-ICD; NICD; Smad; non-Smad; prostate cancer; Snail1; MMP; p300; p21; PAI1; ubiquitination; cleavage; ICD; invasion; HES1; signaling; patologi; Pathology;

   Sammanfattning : Prostate cancer is the most common cancer in men, with the incidence rapidly increasing in Europe over the past two decades. Reliable biomarkers for prostate cancer are currently unavailable. Thus, there is an urgent need for improved biomarkers to diagnose prostate cancer at an early stage and to determine the best treatment options. LÄS MER

3. 2. Expression of TGF- isoforms, their receptors and related SMAD proteins in brain pathology : Immunohistochemical studies focusing on infarcts, abscesses and malignant gliomas

   Författare :Ahmad Khaled Ata; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; TGF-beta receptor; SMAD; brain; infarct; abscess; glioma; experimental; human; Genetik; Clinical genetics; Klinisk genetik; Genetics; genetik;

   Sammanfattning : This thesis focuses on the immunohistochemical expression of transforming growth factor beta(TGFβ) isoforms, their receptors and TGF-β-related SMAD proteins in brain pathology, chiefly in-farcts. One key question was whether the expressions of these compounds are altered within glial cells, endothelial cells of microvessels and other cell types in the vicinity of infarcts. LÄS MER

4. 3. Smad signaling in hematopoietic stem cell biology

   Författare :Göran Karlsson; Avdelningen för molekylärmedicin och genterapi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Smad7; Smad4; microarray; retroviral-mediated gene expression; conditional knockout; transforming growth factor beta; smad signaling; hematopoiesis; hematopoietic stem cells; Alk5; Medicine human and vertebrates ; Medicin människa och djur ;

   Sammanfattning : Hematopoietic stem cells (HSCs) are primitive tissue-specific somatic stem cells, responsible for the maintenance and replenishment of the bone marrow (BM) and subsequently the entire blood system. The never-ending ability to differentiate into all the mature hematopoietic lineages makes these HSCs attractive candidates for use in future regenerative medicine. LÄS MER

5. 4. Regulation of hematopoiesis by the Smad signaling pathway

   Författare :Ulrika Blank Savukinas; Avdelningen för molekylärmedicin och genterapi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine human and vertebrates ; retroviral mediated gene expression; conditional knockout; hematopoietic stem cell; hematopoiesis; Transforming growth factor-beta; Smad signaling; Medicin människa och djur ;

   Sammanfattning : Hematopoietic stem cells (HSCs) reside in the bone marrow (BM) of adult individuals and are ultimately responsible for the continuous production of blood cells throughout life. The regulation of HSCs in vivo is tightly regulated by both intrinsic and extrinsic factors. LÄS MER

7. 5. Regulation of TGF-β Signaling by Post-Translational Modifications

   Författare :Peter Lönn; Aristidis Moustakas; Carl-Henrik Heldin; Petra Knaus; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TGF-β; Smad; PARP-1; PARG; ALK5; SIK; signal transduction; transcription; post-translational modification; phosphorylation; ubiquitin; ADP-ribosylation; DNA-binding; receptor degradation; Cell and molecular biology; Cell- och molekylärbiologi; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

   Sammanfattning : Transforming growth factor-β (TGF-β) signaling is initiated when the ligand binds to type II and type I serine/threonine kinase receptors at the cell surface. Activated TGF-β type I receptors phosphorylate R-Smads which relocate, together with co-Smads, to the cell nucleus and regulate transcription. LÄS MER
