BACKGROUND: Chronic disseminated candidiasis (CDC) is a severe invasive fungal infection principally observed during neutrophil recovery in patients with acute leukemia treated with intensive chemotherapy. Its pathophysiology remains unclear. We describe the management of six children with symptomatic CDC who did not respond to antifungal therapy. METHODS: The databases of the hematology-oncology departments of two tertiary pediatric medical centers were searched for all patients diagnosed with CDC from 2003 to 2015 who responded to corticosteroids after failing antifungal therapy...

Strongyloides stercoralis is an intestinal nematode that can cause disseminated infection in an immunocompromised host. It is most commonly acquired in developing countries. It was previously a common infection in many parts of the United States, particularly in the Appalachian region, but is rarely identified currently. Here, we describe a patient born and raised in Appalachia, with no history of travel outside the United States, who presented with chronic lymphocytic leukemia and S. stercoralis hyperinfection characterized by acute respiratory failure, altered mental status, and extended-spectrum-beta-lactamase Klebsiella pneumoniae bacteremia...

OBJECTIVES: Multipotent mesenchymal stromal cells (MSCs) play a central role within the bone marrow (BM) niche, supporting hematopoiesis via soluble factors like cytokines and chemokines. In our study, we sought to investigate the effect of blocking transforming growth factor beta 1 (TGF-β1) and C-X-C motif chemokine 12 (CXCL12) receptor CXCR4 on acute myeloid leukemia (AML) cells in an MSC co-culture system. METHODS: Human MSCs were obtained by BM aspirates and their phenotype and functional properties were confirmed in vitro...

Novel therapies have potential to improve outcomes in patients with acute myeloid leukemia (AML) harboring FLT3-ITD mutations that have high risk of relapse and poor survival following standard of care (SOC) cytarabine/anthracycline-based induction/consolidation chemotherapy. Quizartinib is a selective and highly potent FLT3 inhibitor that has shown strong single-agent activity in relapsed or refractory (R/R) AML. This phase 1, open-label, sequential group dose-escalation trial (NCT 01390337) is the first evaluating safety and tolerability of quizartinib in combination with SOC chemotherapy in newly diagnosed AML (ndAML)...

Activating mutations in the gene encoding the cell-cell contact signaling protein Notch1 are common in human T cell acute lymphoblastic leukemias (T-ALLs). However, expressing Notch1 mutant alleles in mice fails to efficiently induce the development of leukemia. We performed a gain-of-function screen to identify proteins that enhanced signaling by leukemia-associated Notch1 mutants. The transcription factors MAFB and ETS2 emerged as candidates that individually enhanced Notch1 signaling, and when coexpressed, they synergistically increased signaling to an extent similar to that induced by core components of the Notch transcriptional complex...

Combining NK cell adoptive transfer with hypomethylating agents (HMA) is an attractive therapeutic approach for patients with acute myeloid leukemia (AML). However, data regarding the impact of HMA on NK cell functionality are mostly derived from in vitro studies with high non-clinical relevant drug concentrations. Here, we report a comparative study of azacitidine and decitabine in combination with allogeneic NK cells generated from CD34(+) hematopoietic stem and progenitor cells (HSPC-NK cells) in in vitro and in vivo AML models...

Plasmacytoid dendritic cells (pDCs) promote tolerance in solid organ transplants and hematopoietic stem cell transplantation (HSCT). pDCs originate from CD34(+) hematopoietic progenitors. Following allogeneic hematopoietic stem cell transplant (allo-HSCT), pDC reconstitution in the BM and PB gradually attain levels similar to those in healthy individuals. We have investigated the recovery of pDC following allo-HSCT as a means to predict successful marrow engraftment. We retrospectively studied immune reconstitution of pDC in the BM of 48 patients following allo-HSCT for initial diagnoses of leukemia or other malignancies...

Forkhead box (FOX) genes encode transcription factors, which regulate embryogenesis and play an important role in hematopoietic differentiation and in mesenchymal niche maintenance. Overexpression of the family member FOXC1 has been reported in solid tumors and acute myeloid leukemia (AML). We studied FOXC1 expression and function in acute promyelocytic leukemia (APL) and normal hematopoietic progenitors. FOXC1 mRNA and protein levels were significantly lower in primary marrow samples from 27 APL patients, as compared to samples obtained from 27 patients with other AML subtypes, and 5 normal CD34+ hematopoietic cells...

The genetic heterogeneity of acute myeloid leukemia (AML) and the variable responses of individual patients to therapy suggest that different AML genotypes may influence the bone marrow (BM) microenvironment in different ways. We performed gene expression profiling of bone marrow mesenchymal stromal cells (BM-MSC) isolated from normal C57BL/6 mice or mice inoculated with syngeneic murine leukemia cells carrying different human AML genotypes, developed in mice with Trp53 wild-type or nullgenetic backgrounds...

Dysregulation of glucose/lactate dynamics plays a role in cancer progression, and MCTs are key elements in metabolic remodeling. VEGF is a relevant growth factor in the maintenance of bone marrow microenvironment and it is also important in hematological diseases. Our aim was to investigate the role of VEGF in the metabolic adaptation of Acute myeloid leukemia (AML) cells by evaluating the metabolic profiles and cell features according to the AML lineage and testing lactate as a metabolic coin. Our in vitro results showed that AML promyelocytic (HL60) and monocytic (THP1) (but not erythroid- HEL) lineages are well adapted to VEGF and lactate rich environment...

Myelodysplastic syndromes (MDS) are a group of myeloid hematological malignancies, with a high risk of progression to acute myeloid leukemia (AML). To explore the role of acquired mutations in MDS, 111 MDS-associated genes were screened using next-generation sequencing (NGS), in 125 patients. One or more mutations were detected in 84% of the patients. Some gene mutations are specific for MDS and were associated with disease subtypes, and the patterns of mutational pathways could be associated with progressive MDS...

The translocation t(4;11)(q21;q23) is the hallmark genetic abnormality associated with infant pro-B acute lymphoblastic leukemia (B-ALL) and has the highest frequency of rearrangement in Mixed-lineage leukemia (MLL) leukemias. Unlike other MLL translocations, MLL-AF4-induced proB-ALL is exceptionally difficult to model in mice/humans. Previous work has investigated the relevance of the reciprocal translocation fusion protein AF4-MLL for t(4;11) leukemia, finding that AF4-MLL is capable of inducing proB-ALL without requirement for MLL-AF4 when expressed in murine hematopoietic stem/progenitor cells (HSPCs)...

Mechanical properties of biological structures play an important role in regulating cellular activities and are critical for understanding metabolic processes in cancerous cells and the effects of drugs. For some cancers, such as acute myeloid leukaemia, chemotherapy is one of preferential methods. However, due to the lack of selectivity to cancer cells, cytostatic agents cause toxicity to normal tissues. Here, we study the effect of doxorubicin (DOX) on the mechanical properties of DNA molecules, leukemic blast cells and erythrocytes, using optical tweezers...

The importance of microRNAs (miRNAs) are shown during various cancers including acute myeloid leukemia (AML). MiR-182-5p functions as an oncogene or a potential suppressive miRNA in cancers, but its expression and function in AML is unknown. The purpose is to investigate the roles of miR-182-5p in AML in this study. MiR-182-5p was examined in the blood samples of AML and it was found that miR-182-5p expression levels were higher in AML tissues than it in their normal controls, so did in the AML cells. BCL2L12 and BCL2 were predicted as target genes of miR-182-5p and verified using luciferase reporter assay...

The differential diagnoses of reactive arthritis presenting as arthralgia should be considered as diverse disorders, especially when the symptoms cannot be fully explained by some definite diseases. Do not ignore the indication of bone marrow aspiration. We reported a 50-year-old woman who complained of arthralgia, recurrent fever and rash 9 months ago. Laboratory exams showed mild leukopenia, anemia, thrombocytopenia and increased lymphocyte proportion. She was treated with glucocorticoid after the diagnosis of connective tissue disease was suspected...

Rho guanine exchange factors (GEFs), the enzymes that stimulate Rho GTPases, are deemed as potential therapeutic targets owing to their protumorigenic functions. However, the understanding of the spectrum of their pathobiological roles in tumors is still very limited. We report here that the GEF Vav1 unexpectedly possesses tumor-suppressor functions in immature T cells. This function entails the noncatalytic nucleation of complexes between the ubiquitin ligase Cbl-b and the intracellular domain of Notch1 (ICN1) that favors ICN1 ubiquitinylation and degradation...
