UC San Diego Researchers Identify Factor Boosting Leukemia’s Aggressiveness
A team of researchers identify a particular relationship that can promote notably aggressive leukemias and lymphomas. They looked specifically at a protein called B cell activating factor or BAFF, which is produced in high levels by “nurselike cells” in the chronic lymphocytic leukemia microenvironment. [Press release from the University of California, San Diego discussing online prepublication in the Proceedings of National Academy of Sciences USA]

Some Leukemia Patients May Be Able to Safely Stop Treatment
New medical trials suggest some chronic leukemia patients who are in complete remission may be cured by the standard drug used to treat the condition and can safely discontinue its use. [Press release from PhysOrg discussing online prepublication in The Lancet Oncology]

CURRENT PUBLICATIONS (Ranked by Impact Factor of the Journal)


Genome-Wide Identification of Human microRNAs Located in Leukemia-Associated Genomic Alterations
Here, researchers investigated miRNAs relevant to acute myeloid leukemia (AML) by; 1) mapping miRNAs within leukemia-associated genomic alterations in human AML cell lines by high-resolution genome arrays, and 2) evaluating absolute expression of these miRNAs by massively parallel small RNA sequencing. [Blood]

Dynamic Combinatorial Interactions of RUNX1 and Cooperating Partners Regulates Megakaryocytic Differentiation in Cell Line Models
Researchers used megakaryocytic cell lines to characterize the network of RUNX1 targets and cooperating transcription factors (TFs) in differentiating megakaryocytes and demonstrated how dynamic partnerships between RUNX1 and cooperating TFs facilitated regulatory plasticity and specificity during this process. [Blood]

B Cell Activating Factor and v-Myc Myelocytomatosis Viral Oncogene Homolog (c-Myc) Influence Progression of Chronic Lymphocytic Leukemia
This study reveals an important relationship between B cell activating factor and c-MYC in chronic lymphocytic leukemia which may affect disease development and progression, and suggests that inhibitors of the canonical NF-(kappa)B pathway may be effective in treatment of patients with this disease. [Proc Natl Acad Sci USA]

Follicular Dendritic Cell-Induced MicroRNA-Mediated Upregulation of PRDM1 and Downregulation of BCL-6 in Non-Hodgkin’s B Cell Lymphomas
The studies define a novel regulatory mechanism in which the follicular dendritic cell, through induction of miRNAs in B lymphocytes, orchestrates the regulation of transcription factors, promotes germinal center B cell survival and differentiation. [Leukemia]

Protein Tyrosine Phosphatase Receptor Type Gamma Is a Functional Tumor Suppressor Gene Specifically Downregulated in Chronic Myeloid Leukemia
The findings establish, for the first time, protein tyrosine phosphatase receptor type gamma as a tumor suppressor gene involved in the pathogenesis of chronic myelogenous leukemia, suggesting its use as a potential diagnostic and therapeutic target. [Cancer Res]

PML-RAR(Alpha) and Dnmt3a1 Cooperate In Vivo to Promote Acute Promyelocytic Leukemia
Here, researchers show that increased expression of Dnmt3a1 cooperates with PML-RAR(alpha) in vivo to promote early lethality secondary to myeloid expansion and dysfunction in primary mice. [Cancer Res]

Histone Methyltransferase MLL1 Regulates MDR1 Transcription and Chemoresistance
This is the first identification of a histone methyltransferase and its leukemogenic rearrangement that regulates expression of an ATP-binding cassette drug transporter, suggesting a new target for circumvention of tumor multidrug resistance. [Cancer Res]


Discontinuation of Imatinib in Patients with Chronic Myeloid Leukemia Who Have Maintained Complete Molecular Remission for at Least 2 Years: The Prospective, Multicentre Stop Imatinib (STIM) Trial
Researchers aimed to assess whether imatinib can be discontinued without occurrence of molecular relapse in patients in complete molecular remission while on imatinib. [J Clin Oncol]

Infusion of HLA-Mismatched Peripheral Blood Stem Cells Improves Outcome of Chemotherapy for Acute Myeloid Leukemia in Elderly Patients
These results indicate that granulocyte colony-stimulating factor-mobilized donor peripheral blood stem cells in combination with conventional chemotherapy may provide a promising treatment modality for acute myeloid leukemia in elderly patients. [Blood]

A Phase II Study of Combination Therapy with Arsenic Trioxide and Gemtuzumab Ozogamicin in Patients with Myelodysplastic Syndromes or Secondary Acute Myeloid Leukemia
In the current study, phase II study data of arsenic trioxide and gemtuzumab ozogamicin in CD33-positive patients with myelodysplastic syndrome and secondary acute myeloid leukemia were presented. [Cancer]


CIRM Awards $5.8 Million to Two UCSD Researchers for Early Translational Research Studies
