Special Issue Information
Dear Colleagues,
The myeloproliferative neoplasms (MPN) are a group of rare chronic disorders characterized by the clonal proliferation of one or more blood cell lines in the myeloid lineage, and include primary myelofibrosis (PMF), chronic myeloid leukemia (CML), polycythemia vera (PV), essential thrombocythemia (ET), chronic neutrophilic leukemia (CNL), chronic eosinophilic leukemia not otherwise specified (CEL-NOS), and MPN unclassifiable (MPN-U).
As a result of increasingly economical and available next-generation sequencing technologies, genetic studies in the past decade have improved our understanding of the molecular basis of MPNs. Recent breakthroughs include the discovery of activating mutations in CSF3R in the majority of patients with CNL, the presence of a driver mutation in the JAK2, MPL or CALR genes in ET and PMF (and the JAK2V617F mutation in approximately 95% of patients with PV), as well as activating mutations of KIT in some patients with CEL-NOS. Also, some very rare cases of familial hereditary MPNs have been described, caused by inherted germline mutations.
MPNs often progress to fibrosis or acute leukemia, both associated with very poor clinical outcome. Besides defining biomarkers for diagnosis, mutational studies have revealed the prognostic relevance of many somatic mutations, helping to improve the risk stratification of patients with MPNs.
Finally, knowledge of the molecular basis of MPNs has helped identify targets for directed therapy. The constitutive activation of tyrosine kinases in hematopoietic stem cells is a common molecular basis of the MPNs, with tyrosine kinase inhibitor therapy (such as imatinib, dasatinib, ruxolitinib or midostaurin) used with varying degrees of success to treat MPN. Other molecular mechanisms have also been revealed and numerous agents in various stages of development as single or combination therapies. Despite such advancements, our understanding of the molecular pathogenesis of the MPNs – particularly CNL, CEL-NOS and MPN-U – is still insufficient and treatment options limited.
In this Special Issue we are particularly interested in original papers and review articles that address developments in our understanding of the molecular basis of myelofibrosis and the MPNs, as well as manuscripts related to the keywords listed below.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
