Hypothetical Atopic Dermatitis-Myeloproliferative Neoplasm Syndrome

Atopic dermatitis (AD) is a chronic inflammatory skin disease. Myeloproliferative neoplasms (MPNs) are hematopoietic malignancies caused by uncontrolled proliferation of hematopoietic stem/progenitor cells. Recent studies have described several mutant mice exhibiting both AD-like skin inflammation and MPN. Common pathways for skin inflammation encompass overexpression of thymic stromal lymphopo...

Evaluation of JAK2V617F mutation prevalence in myeloproliferative neoplasm by AS-RT-PCR

Abstract Objective JAK2 is a non-receptor tyrosine kinase that plays a major role in myeloid disorders. JAK2V617F 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. Methods In this study we evaluated RNA from 89 pati...

Inflammation as a Driver of Clonal Evolution in Myeloproliferative Neoplasm

Our understanding of inflammation's role in the pathogenesis of myeloproliferative neoplasm (MPN) is evolving. The impact of chronic inflammation, a characteristic feature of MPN, likely goes far beyond its role as a driver of constitutional symptoms. An inflammatory response to the neoplastic clone may be responsible for some pathologic aspects of MPN. Moreover, JAK2V617F mutated hematopoietic...

Pathogenetic mechanisms of thrombosis in patients with myeloproliferative neoplasm

In the diagnostic criteria of these neoplasms, besides haematological tests and osteomedular biopsy an important role is played by the JAK2V617F, CALR and Mpl mutational status testing.1 Numerous researches involved the presence of JAK mutation in increasing the risk of thrombosis; in this way, along with advanced age and history of thrombosis in the classification criteria in “high risk” forms...
