3. New treatments for rare bone diseases: hypophosphatemic rickets/osteomalacia
Abstract Phosphorus is one of the most abundant minerals in the human body; it is required to maintain bone integrity and mineralization, in addition to other biological processes. Phosphorus is regulated by parathyroid hormone, 1,25-dihydroxyvitamin D3 [1,25(OH)2D3], and fibroblast growth factor 23 (FGF-23) in a complex set of processes that occur in the gu

5. Ultraconserved long non-coding RNA uc.112 is highly expressed in childhood T versus B-cell acute lymphoblastic leukemia
ABSTRACT Aberrant expression of long non-coding RNAs (lncRNAs) has been detected in several types of cancer, including acute lymphoblastic leukemia (ALL), but lncRNA mapped on transcribed ultraconserved regions (T-UCRs) are little explored. The T-UCRs uc.112, uc.122, uc.160 and uc.262 were evaluated by quantitative real-time PCR in bone marrow samples from c

6. 5-Azacytidine restores interleukin 6-increased production in mesenchymal stromal cells from myelodysplastic patients
ABSTRACT Introduction: Myelodysplastic syndromes (MDS) are a heterogeneous group of clonal hematological diseases. In addition to defects in hematologic progenitor and stem cells, dysfunctions in the bone marrow microenvironment (BMM) participate in the MDS pathogenesis. Furthermore, the immune response is deregulated by the pro-inflammatory response prevai

7. Can p63 serve as a biomarker for diagnosing giant cell tumor of bone? A systematic review and meta-analysis
ABSTRACT BACKGROUND: Tumor protein p63 (p63) has been reported to be highly expressed in giant cell tumor of bone (GCTB). Whether p63 can be treated as a diagnostic marker for GCTB remains unclear. OBJECTIVE: We conducted a meta-analysis to evaluate the applicability of p63 in diagnosing GCTB. DESIGN AND SETTING: Systematic review and meta-analysis carrie

12. Bone Marrow Mesenchymal Stem Cells Regulate Coagulation and Inflammation Together in Methotrexate Induced Lung Injury Rat Model
Abstract Clinical research has shed the light on the relation between coagulation and inflammation. Coagulation cascade is activated in lung injury resulting in thrombotic and fibrotic lesions. Such a cascade is initiated by inflammation, then the two systems intense each other. New therapies that modulate coagulation and inflammation will be more successfu
