    مصطلحات موضوعية: Adult, Male, Vascular Endothelial Growth Factor A, Hematopoiesis and Stem Cells, Blotting, Western, Immunology, Spleen, Biology, Real-Time Polymerase Chain Reaction, Primary myelofibrosis (PMF) is characterized by fibrosis, ineffective hematopoiesis in marrow, and hematopoiesis in extramedullary sites and is associated with abnormal megakaryocyte (MK) development and increased transforming growth factor (TGF)-β1 release. To clarify the role of TGF-β1 in the pathogenesis of this disease, the TGF-β1 signaling pathway of marrow and spleen of the Gata1(low) mouse model of myelofibrosis (MF) was profiled and the consequences of inhibition of TGF-β1 signaling on disease manifestations determined. The expression of 20 genes in marrow and 36 genes in spleen of Gata1(low) mice was altered. David-pathway analyses identified alterations of TGF-β1, Hedgehog, and p53 signaling in marrow and spleen and of mammalian target of rapamycin (mTOR) in spleen only and predicted that these alterations would induce consequences consistent with the Gata1(low) phenotype (increased apoptosis and G1 arrest both in marrow and spleen and increased osteoblast differentiation and reduced ubiquitin-mediated proteolysis in marrow only). Inhibition of TGF-β1 signaling normalized the expression of p53-related genes, restoring hematopoiesis and MK development and reducing fibrosis, neovascularization, and osteogenesis in marrow. It also normalized p53/mTOR/Hedgehog-related genes in spleen, reducing extramedullary hematopoiesis. These data identify altered expression signatures of TGF-β1 signaling that may be responsible for MF in Gata1(low) mice and may represent additional targets for therapeutic intervention in PMF, Biochemistry, Transforming Growth Factor beta1, Mice, Bone Marrow, Fibrosis, Biomarkers, Tumor, medicine, Animals, Humans, GATA1 Transcription Factor, RNA, Messenger, RNA, Small Interfering, Myelofibrosis, PI3K/AKT/mTOR pathway, Oligonucleotide Array Sequence Analysis, Ineffective Hematopoiesis, Reverse Transcriptase Polymerase Chain Reaction, Gene Expression Profiling, TOR Serine-Threonine Kinases, Cell Biology, Hematology, Middle Aged, Flow Cytometry, medicine.disease, Chemokine CXCL12, Extramedullary hematopoiesis, Disease Models, Animal, Haematopoiesis, medicine.anatomical_structure, Primary Myelofibrosis, Case-Control Studies, Cancer research, Cytokines, Bone marrow, Signal Transduction
