Background: JAK2 is a nonreceptor tyrosine kinase that plays a major role in myeloid disorders. This mutation is characterized by a G to T transverse at nucleotide 1849 in exon 12 of the JAK2 gene, located on the chromosome 9p, leading to a substitution of valine to phenylalanine at amino acid position 617 in the JAK2 protein. In this study we compared the amplification refractory mutation (ARM...
Refractory anemia with ring sideroblasts associated with marked thrombocytosis (RARS-T) and granulocytic sarcoma are two rare myeloid neoplasms. RARS-T is a Myelodysplastic/Myeloproliferative Neoplasm (MDS/MPN) characterized by overlapping myeloproliferative (platelets count higher than 450x109/L associated with proliferation of large atypical megakaryocytes similar than those observed in essen...
In myeloid malignancies, the neoplastic clone outgrows normal hematopoietic cells toward BM failure. This event is also sustained by detrimental stromal changes, such as BM fibrosis and osteosclerosis, whose occurrence is harbinger of a dismal prognosis. We show that the matricellular protein SPARC contributes to the BM stromal response to myeloproliferation. The degree of SPARC expression in B...
