Kruppel Like Factor 7 Overexpression Suppresses Hematopoietic Stem and Progenitor Cell Function
Increased expression of kruppel like factor 7 (KLF7) is an independent predictor of poor outcome in pediatric acute lymphoblastic leukemia. The contribution of KLF7 to hematopoiesis has not been previously described. Here, researchers characterized the effect on murine hematopoiesis of the loss of KLF7 and enforced expression of KLF7.

Cyclin D3 Coordinates the Cell Cycle during Differentiation to Regulate Erythrocyte Size and Number
By examining human and mouse primary erythroid cells, researchers demonstrated that the CCND3 gene product cyclin D3 regulates the number of cell divisions that erythroid precursors undergo during terminal differentiation, thereby controlling erythrocyte size and number. [Genes Dev] Abstract | Press Release

Adaptor Protein Lnk Binds to and Inhibits Normal and Leukemic FLT3
Researchers showed that through direct binding to FLT3, Lnk suppresses wild-type FLT3/internal tandem duplications-dependent signaling pathways involved in the proliferation of hematopoietic cells. [Blood] Abstract

Conditional TRF1 Knockout in the Hematopoietic Compartment Leads to Bone Marrow Failure and Recapitulates Clinical Features of Dyskeratosis Congenita
To address a possible role for TRF1 dysfunction in bone marrow failure, researchers generated a mouse model with conditional TRF1 deletion in the hematopoietic system. [Blood] Abstract | Press Release

Hematopoietic Overexpression of the Transcription Factor Erg Induces Lymphoid and Erythro-Megakaryocytic Leukemia
Investigators suggested that E-twenty-six-related gene (Erg) overexpression induces the development of not only lymphoid leukemia but also erythro-megakaryocytic leukemia. [Proc Natl Acad Sci USA] Abstract

Clonal Evolution of Preleukemic Hematopoietic Stem Cells Precedes Human Acute Myeloid Leukemia
Investigators proposed that serial acquisition of mutations occurs in self-renewing hematopoietic stem cells (HSCs). They investigated this model through genomic analysis of HSCs from six patients with de novo acute myeloid leukemia. [Sci Transl Med] Abstract | Press Release

Human Responses against HER-2-Positive Cancer Cells in Human Immune System-Engrafted Mice
Researchers used human immune system mice to study human immune responses against human HER-2-positive cancer cells and their ability to control tumor growth and metastasis. BALB/c Rag2-/-, Il2rg-/- mice were engrafted with CD34+ or CD133+ human cord blood hematopoietic stem cells and vaccinated with human HER-2-positive cancer cells SK-OV-3 combined to human IL-12.

The Multi-Kinase Inhibitor TG02 Overcomes Signaling Activation by Survival Factors to Deplete MCL1 and XIAP and Induce Cell Death in Primary Acute Myeloid Leukemia Cells
Scientists evaluated the in vitro toxicity of TG02 to primary acute myeloid leukemia cells in the presence of survival signaling pathway activation by cytokines and fibronectin. [Br J Haematol] Abstract

The Peptide Derived from the Ig-Like Domain of Human Herpes Virus 8 K1 Protein Induces Death in Hematopoietic Cancer Cells
Researchers showed that the S20-3 peptide can selectively induce the death of malignant hematological cell lines in Fas- and/or TNFRI-dependent mechanisms, suggesting the K1-derived peptide or peptidomimetic may have promising therapeutic potential for the treatment of hematological cancers. [J Exp Clin Cancer Res] Abstract | Full Article


HLA-C-Dependent Prevention of Leukemia Relapse by Donor Activating KIR2DS1
Researchers assessed clinical data, HLA genotyping results, and donor cell lines or genomic DNA for 1277 patients with acute myeloid leukemia who had received hematopoietic stem-cell transplants from unrelated donors matched for HLA-A, B, C, DR, and DQ or with a single mismatch. [N Engl J Med] Abstract

Long-Term Efficacy and Safety of Arsenic Trioxide for First-Line Treatment of Elderly Patients with Newly Diagnosed Acute Promyelocytic Leukemia
A total of 33 patients aged 60 years or older with de novo acute promyelocytic leukemia were treated with single-agent arsenic trioxide for remission induction and post remission therapy. The post remission therapy continued for up to four years. [Cancer] Abstract

Hematopoietic Stem Cell Mobilization: Updated Conceptual Renditions
Much effort has been made trying to explain the complex mechanism(s) by which HSPCs leave the marrow. This review reports some of the more recent advances about mobilization, with an attempt to reconcile some of the seemingly inconsistent data in mobilization and to interject some commonalities among different mobilization regimes. [Leukemia] Abstract
