TOP STORY

Transplantation of Mouse HSCs Genetically Modified to Express a CD4-Restricted TCR Results in Long-Term Immunity that Destroys Tumors and Initiates Spontaneous Autoimmunity

In this study, researchers sought to alter and enhance long-term host immunity by genetically modifying, then transplanting, mouse hematopoietic stem cells (HSCs). [J Clin Invest]

SCIENCE NEWS

Gene Therapy for Metastatic Melanoma in Mice Produces Complete Remission, Indiana University Cancer Researchers Report
A potent anti-tumor gene introduced into mice with metastatic melanoma has resulted in permanent immune reconfiguration and produced a complete remission of their cancer, according to an article.

CURRENT PUBLICATIONS (Ranked by Impact Factor of the Journal)

LABORATORY RESEARCH

Fine-Mapping at Three Loci Known to Affect Fetal Hemoglobin Levels Explains Additional Genetic Variation
Researchers used resequencing and genotyping in African Americans with sickle cell anemia to characterize associations with fetal hemoglobin levels at the BCL11A, HBS1L-MYB and beta-globin loci. [Nat Genet]

Zebrafish microRNA-126 Determines Hematopoietic Cell Fate through c-Myb
In this study, researchers show that miR-126 is a novel physiological regulator of the proto-oncogene c-myb during definitive hematopoiesis. [Leukemia]

DAMP-Mediated Autophagy Contributes to Drug Resistance
High mobility group box 1 (HMGB1) is a prototypical damage associated molecular pattern molecule (DAMP) and is associated with the hallmarks of cancer. Recently researchers found that HMGB1 release after chemotherapy treatment is a critical regulator of autophagy and a potential drug target for therapeutic interventions in leukemia. [Autophagy]

FIP200, an Essential Component of Mammalian Autophagy Is Indispensible for Fetal Hematopoiesis
Researchers show that mice lacking focal adhesion kinase family interacting protein of 200 kD (FIP200) in hematopoietic cells (CKO mice) experience perinatal lethality associated with severe erythroblastic anemia. [Autophagy]

HoxA10 Regulates Transcription of the Gene Encoding Transforming Growth Factor Beta 2 (TGFB2) in Myeloid Cells
The current study identifies the gene encoding transforming growth factor B2 (TGFB2) as a HoxA10-target-gene. [ J Biol Chem]

A New, Lineage Specific, Autoup-Regulation Mechanism for Human Glucocorticoid Receptor Gene Expression in 697 Pre-B-Acute Lymphoblastic Leukemia Cells
The data suggest a hormone activated, lineage-specific mechanism to control the autoup-regulation of human GC receptor (hGR ) gene expression in 697 pre-B-acute lymphoblastic leukemia cells via steroid-mediated changes in GR coregulator expression. [Mol Endocrinol]

CLINICAL RESEARCH

The Prognostic Impact and Stability of Isocitrate Dehydrogenase 2 Mutation in Adult Patients with Acute Myeloid Leukemia
Serial analyses of isocitrate dehydrogenase 2 (IDH2) mutations at both diagnosis and relapse in 121 patients confirmed high stability of IDH2 mutations. In conclusion, IDH2 mutation is a stable marker during disease evolution and confers favorable prognosis. [Leukemia]

Regulatory T Cells Predict the Time to Initial Treatment in Early Stage Chronic Lymphocytic Leukemia
Higher regulatory T cell levels had significant and independent prognostic power for predicting the time to initial treatment in patients with low to intermediate stage chronic lymphocytic leukemia. [Cancer]

INDUSTRY NEWS

Isis and Xenon Collaborate to Develop Antisense Drugs Against Hemojuvelin and Hepcidin
Isis Pharmaceuticals, Inc. and Xenon Pharmaceuticals Inc. announced a new collaboration to discover and develop antisense drugs as novel treatments for the common disease anemia of inflammation. [Isis Pharmaceuticals, Inc. Press Release]

AesRx Announces Collaboration with NIH to Develop Aes-103 for Sickle Cell Disease
AesRx, LLC, announced that it has entered into a collaboration with the National Institutes of Health (NIH) to take AesRx’s investigational sickle cell therapeutic, Aes-103, through pre-clinical development and initial clinical trials, including two trials in sickle cell patients. [AesRx, LLC, Press Release]

Bayer, J&J Anti-Clot Drug Shines in Stroke Trial
A once-daily pill being developed by Bayer AG and Johnson & Johnson was better at preventing stroke than standard treatment, with less risk of the most worrisome types of bleeding, researchers said. [Reuters]
