1. 11. The Role of Hox Transcription Factors in the Regulation of Hematopoiesis

   Sammanfattning : Hematopoiesis is a lifelong, dynamic process, originating from a low number of hematopoietic stem cells (HSCs) residing in the adult bone marrow with the ability to self-renew and generate all blood lineages throughout life. Recent findings have demonstrated that the Homeobox (Hox) transcription factors are important regulators of both normal and malignant hematopoiesis, controlling proliferation, differentiation and self-renewal of hematopoietic cells at different levels of the hematopoietic hierarchy.

3. 12. Regulation of cell polarity and invasion by TGF-β and BMP signaling

   Författare :Mahsa Shahidi Dadras; Aristidis Moustakas; Petra Knaus; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cancer; cancer stem cells; invasion; metastasis; polarity; TGF-β signaling.;

   Sammanfattning : Transforming growth factor β (TGF-β) and bone morphogenetic protein (BMP) signaling pathways are involved in many physiological processes during embryonic and adult life. TGF-β promotes epithelial to mesenchymal transition (EMT). We identified a gene target of TGF-β signaling, encoding the salt-inducible kinase 1 (SIK1). LÄS MER

4. 13. 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

5. 14. Interplay Between Cell of Origin and Oncogenic Activation in Glioma

   Författare :Yiwen Jiang; Lene Uhrbom; Anders Persson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioma; PDGF; cell of origin; Sox5; glioma initiating cells; Oncology; Onkologi;

   Sammanfattning : Glioma is the most frequent primary tumor of the central nervous system. By using the RCAS/tv-a mouse glioma model, we have studied mechanisms controlling glioma development and the effect of cell of origin on these processes.SOX5 was identified as a brain tumor locus in a retroviral insertional mutagenesis screen of PDGF-B induced mouse gliomas.

7. 15. Novel Insights into Haematopoietic Stem Cell Regulation and Function

   Författare :Sarah Warsi; Avdelningen för molekylärmedicin och genterapi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Haematopoiesis; Haematopoietic stem cell; Stem cell regulation; Haematopoietic stem cell transplantation;

   Sammanfattning : The haematopoietic stem cell (HSC) is a somatic stem cell essential for life long haematopoiesis; HSCs have the capability to differentiate into all mature types of blood cells and can also undergo self-renewal to maintain their own numbers. They also have the potential to reconstitute a complete haematopoietic system following HSC transplantation, also known as bone marrow transplantation, which is used to treat many haematopoietic disorders.
