TOP STORYBcor Loss Perturbs Myeloid Differentiation and Promotes Leukaemogenesis Inactivation of BCL6 Corepressor (Bcor) in hematopoietic stem cells resulted in expansion of myeloid progenitors and co-operated with oncogenic KrasG12D in the initiation of aggressive and fully transplantable acute leukemia.

PUBLICATIONS(Ranked by impact factor of the journal)Researchers showed that colorectal cancer-initiating cells (C-ICs) were maintained in a stem-like state through a bivalent epigenetic mechanism. Disruption of the bivalent state through inhibition of the H3K27 methyltransferase EZH2, resulted in decreased self-renewal of patient-derived C-ICs. [Nat Commun] Full Article The Hematopoietic Oxidase NOX2 Regulates Self-Renewal of Leukemic Stem Cells Transcriptional analysis of purified leukemia-initiating stem cell populations revealed that deficiency of NOX2 collapsed the self-renewal program and activated inflammatory and myeloid-differentiation-associated programs. [Cell Rep] Full Article | Graphical Abstract Cancer Stem Cell Self-Renewal as a Therapeutic Target in Human Oral Cancer Treatment of pre-established human oral cancer xenografts with a BMI1 inhibitor resulted in abrogation of tumor progression and reduced the frequency of CSCs in xenografts. The BMI1 inhibitor had therapeutic effects in cisplatin-resistant tumors and could reduce metastases initiated by circulating CSCs. [Oncogene] Abstract Scientists reported that glioblastoma stem-like cells depended on the adaptive activation of ER stress and subsequent activation of lipogenesis and particularly stearoyl CoA desaturase, which promoted ER homeostasis, cytoprotection, and tumor initiation. [Stem Cell Reports] Full Article | Graphical Abstract Inhibition of USP2 Eliminates Cancer Stem Cells and Enhances TNBC Responsiveness to Chemotherapy Investigators identified that USP2 deubiquitinating enzyme was upregulated in CSCs and was a novel regulator of CSCs. Genetic and pharmacological targeting of USP2 substantially inhibited the self-renewal, expansion and chemoresistance of CSCs. [Cell Death Dis] Full Article The authors compiled 15 down-regulated miRNA and their validated and predicted up-regulated targets in HCSC. The targets were enriched for several cancer cell stemness hallmarks and CSC pre-metastatic niche, which supported these miRNAs’ role in suppression of HCSC neoplastic transformation.” [Sci Rep] Full Article The immaturity of cultured primary retinoblastoma (RB) cells was demonstrated by highly expressed stem-cell markers and suppressed mature retinal-cell markers. CD133, a neural stem-cell marker being exclusively studied in RB, was found positive in small patches of cells in archival human RB by immunohistochemistry. [Exp Cell Res] Full Article | Graphical Abstract The efficacy of two different oHSVs in prostate cancer sphere-forming cells (PCSCs) was tested alone and in combination with radiation, chemotherapy, and inhibitors of PI3K, Wnt, and NOTCH in vitro, and G47Δ with the PI3K inhibitor BKM120 in a PCSC-derived tumor model in vivo.

REVIEWSStem Cells in Homeostasis and Cancer of the Gut The authors present an overview of the current knowledge on intestinal stem cells (ISCs) in homeostasis and their role in malignant transformation. Specifically, the dynamics of cancer stem cells bear important resemblance to ISC functionality.

INDUSTRY NEWSImbrium Therapeutics L.P. announced that the FDA has granted orphan drug designation to its investigational drug tinostamustine, a potentially first-in-class alkylating deacetylase inhibiting molecule being studied in early phase clinical trials, for the treatment of T-cell prolymphocytic leukemia. [Imbrium Therapeutics L.P. (Business Wire, Inc.)] Press Release Inaugural AACR-Novocure Tumor Treating Fields Research Grant Recipients Announced The recipients of the American Association for Cancer Research (AACR)-Novocure Tumor Treating Fields research grants were announced on April 2. The grants represent a joint effort between Novocure and the AACR to promote and support innovative research on tumor treating fields.

POLICY NEWSAustralia Budget Fails to Impress Scientists Australians are just weeks from a national election and the government’s latest budget prioritizes tax cuts, roads and small businesses ahead of spending on science. Projects in nuclear medicine, environment protection and gender equality in science received modest investments. But there was no new money for research grants, and universities would be worse off under the proposal. [Nature News] Editorial India’s Clinical-Trial Rules to Speed Up Drug Approvals India has announced new rules for clinical trials that will speed up drug approvals and remove the requirement for large studies to test the efficacy of drugs that have already been approved in other nations. The country will also introduce regulations for universities undertaking research involving people. [Nature News] Editorial Staff Scientists at the University of California Set to Form a First-of-Its-Kind Union There are 5,000 of them within the University of California system, with titles like project scientist or professional researcher. They’re not on the tenure track, but they power one of the world’s most prolific research institutions. Now, organizers are in the final stages of setting up a first-of-its-kind union exclusively for academic researchers who are not faculty, postdocs, or graduate students. [STAT News] Editorial
