Primary myelofibrosis (formerly known as chronic idiopathic myelofibrosis), has the lowest incidence amongst the chronic myeloproliferative neoplasms and is characterized by a rather short median survival and a risk of progression to acute myeloid leukemia (AML) noted in a small subset of the cases, usually as a terminal event. As observed with other chronic myeloproliferative neoplasms, the bone marrow biopsy may harbor small lymphoid aggregates, often assumed reactive in nature. In our paper, we present a 70-year-old Caucasian male who was diagnosed with primary myelofibrosis, and after 8 years of followup and therapy developed an AML. -
Mirna182 Regulates Percentage of Myeloid and Erythroid Cells in Chronic Myeloid Leukemia
Citation: Cell Death and Disease (2017) 8, e2547; doi:10.1038/cddis.2016.471 OPEN Official journal of the Cell Death Differentiation Association www.nature.com/cddis MiRNA182 regulates percentage of myeloid and erythroid cells in chronic myeloid leukemia Deepak Arya1,2, Sasikala P Sachithanandan1, Cecil Ross3, Dasaradhi Palakodeti4, Shang Li5 and Sudhir Krishna*,1 The deregulation of lineage control programs is often associated with the progression of haematological malignancies. The molecular regulators of lineage choices in the context of tyrosine kinase inhibitor (TKI) resistance remain poorly understood in chronic myeloid leukemia (CML). To find a potential molecular regulator contributing to lineage distribution and TKI resistance, we undertook an RNA-sequencing approach for identifying microRNAs (miRNAs). Following an unbiased screen, elevated miRNA182-5p levels were detected in Bcr-Abl-inhibited K562 cells (CML blast crisis cell line) and in a panel of CML patients. Earlier, miRNA182-5p upregulation was reported in several solid tumours and haematological malignancies. We undertook a strategy involving transient modulation and CRISPR/Cas9 (clustered regularly interspersed short palindromic repeats)-mediated knockout of the MIR182 locus in CML cells. The lineage contribution was assessed by methylcellulose colony formation assay. The transient modulation of miRNA182-5p revealed a biased phenotype. Strikingly, Δ182 cells (homozygous deletion of MIR182 locus) produced a marked shift in lineage distribution. The phenotype was rescued by ectopic expression of miRNA182-5p in Δ182 cells. A bioinformatic analysis and Hes1 modulation data suggested that Hes1 could be a putative target of miRNA182-5p. A reciprocal relationship between miRNA182-5p and Hes1 was seen in the context of TK inhibition. -
Mutations and Prognosis in Primary Myelofibrosis

We studied 879 PMF patients to determine the individual and combinatorial prognostic relevance of somatic mutations. Analysis was performed in 483 European patients and the seminal observations were validated in 396 Mayo Clinic patients. Samples from the European cohort, collected at time of diagnosis, were analyzed for mutations in ASXL1, SRSF2, EZH2, TET2, DNMT3A, CBL, IDH1, IDH2, MPL and JAK2. Of these, ASXL1, SRSF2 and EZH2 mutations inter-independently predicted shortened survival. However, only ASXL1 mutations (HR: 2.02; Po0.001) remained significant in the context of the International Prognostic Scoring System (IPSS). These observations were validated in the Mayo Clinic cohort where mutation and survival analyses were performed from time of referral. ASXL1, SRSF2 and EZH2 mutations were independently associated with poor survival, but only ASXL1 mutations held their prognostic relevance (HR: 1.4; P ¼ 0.04) independent of the Dynamic IPSS (DIPSS)-plus model, which incorporates cytogenetic risk. In the European cohort, leukemia-free survival was negatively affected by IDH1/2, SRSF2 and ASXL1 mutations and in the Mayo cohort by IDH1 and SRSF2 mutations. -

Acute myelofibrosis in patients with acute lymphoblastic leukemia is extremely rare. We report a 4-year-old boy who was diagnosed as having acute massive myelofibrosis and acute lym- phoblastic leukemia. Performing bone marrow aspiration in this patient was difficult (a “dry tap”), and the diagnosis was established by means of a bone marrow biopsy and immunohistopathologic analysis. The prognostic significance of acute myelofibrosis in patients with acute lymphoblastic leukemia is not clear.

Myelodysplastic Syndromes Overview and Types

Learning some basics is a good place to start. ● What Are Myelodysplastic Syndromes? ● Types of Myelodysplastic Syndromes Research and Statistics See the latest estimates for new cases of myelodysplastic syndromes in the US and what research is currently being done. ● Key Statistics for Myelodysplastic Syndromes ● What's New in Myelodysplastic Syndrome Research? What Are Myelodysplastic Syndromes? Myelodysplastic syndromes (MDS) are conditions that can occur when the blood- forming cells in the bone marrow become abnormal. This leads to low numbers of one or more types of blood cells. MDS is considered a type of cancer1. Normal bone marrow 1 ____________________________________________________________________________________American Cancer Society cancer.org | 1.800.227.2345 Bone marrow is found in the middle of certain bones. It is made up of blood-forming cells, fat cells, and supporting tissues. A small fraction of the blood-forming cells are blood stem cells. Stem cells are needed to make new blood cells. There are 3 main types of blood cells: red blood cells, white blood cells, and platelets. Red blood cells pick up oxygen in the lungs and carry it to the rest of the body. These cells also bring carbon dioxide back to the lungs. Having too few red blood cells is called anemia. It can make a person feel tired and weak and look pale. Severe anemia can cause shortness of breath. White blood cells (also known as leukocytes) are important in defending the body against infection. -

ISM is based on (i) molecular profi ling and ex vivo drug sensitivity and resistance testing (DSRT) of patients’ cancer cells to 187 oncology drugs, (ii) clinical implementation of therapies predicted to be effective, and (iii) studying consecutive samples from the treated patients to understand the basis of resistance. Here, application of ISM to 28 samples from patients with acute myeloid leukemia (AML) uncovered fi ve major taxonomic drug-response sub- types based on DSRT profi les, some with distinct genomic features (e.g., MLL gene fusions in subgroup IV and FLT3 -ITD mutations in subgroup V). Therapy based on DSRT resulted in several clinical responses.
