CDKN2A-Independent Role of BMI1 in Promoting Growth and Survival of Ph+ Acute Lymphoblastic Leukemia BMI1 is a key component of the polycomb repressive complex-1 required for maintenance of normal and cancer stem cells. The authors showed that BMI1 expression is important for proliferation and survival of Ph+ acute lymphoblastic leukemia cells and for leukemogenesis of Ph+ cells in vivo. [Leukemia] Abstract Circulating Tumor Cells Exhibit Stem Cell Characteristics in an Orthotopic Mouse Model of Colorectal Cancer The authors aimed to characterize colorectal cancer-derived circulating tumor cells (CTCs) to eventually identify the clinically relevant subfraction of CTCs. [Oncotarget] Full Article Multifunctional Targeting Vinorelbine plus Tetrandrine Liposomes for Treating Brain Glioma along with Eliminating Glioma Stem Cells Targeting conjugates of cholesterol polyethylene glycol polyethylenimine and D-a-tocopheryl polyethylene glycol 1000 succinate vapreotide were newly synthesized for transporting drugs across the blood-brain barrier and targeting glioma cells and glioma stem cells. [Oncotarget] Full Article ASC-J9®, and Not Casodex or Enzalutamide, Suppresses Prostate Cancer Stem/Progenitor Cell Invasion via Altering the EZH2-STAT3 Signals Researchers demonstrated that androgen deprivation therapy with anti-androgens Casodex and Enzalutamide, but not newly identified AR degradation enhancer ASC-J9®, increased prostate cancer (PCa) stem/progenitor population, which might then lead to enhanced PCa cell invasion. [Cancer Lett] Abstract MicroRNA Profiling of Cisplatin-Resistant Oral Squamous Cell Carcinoma Cell Lines Enriched with Cancer-Stem-Cell-Like and Epithelial-Mesenchymal Transition-Type Features Investigators aimed to identify the specific deregulated miRNAs which are responsible for development of resistance phenotype through regulating their resistance related target gene expression in oral squamous cell carcinoma. [Sci Rep] Full Article Novel PKC-ζ to p47phox Interaction Is Necessary for Transformation from Blebbishields Scientists demonstrated that a novel PKC-ζ to p47phox interaction is required for reactive oxygen species production in cancer cells. [Sci Rep] Full Article CD55 Is a HIF-2α Marker with Anti-Adhesive and Pro-Invading Properties in Neuroblastoma Scientists revealed that CD55 is a novel target of hypoxia-inducible factor HIF-2α in neuroblastoma (NB) cells. They showed that HIF-2α expression is sufficient to sustain stem-like features of NB cells, whereas CD55 protein upon HIF-2α expression contributes to growth of colonies and to invasion of cells, but not to stemness features. [Oncogenesis] Full Article Glioma Stem Cells but Not Bulk Glioma Cells Upregulate IL-6 Secretion in Microglia/Brain Macrophages via Toll-Like Receptor 4 Signaling Researchers explored the interaction between glioma stem cells (GSCs) and microglia/brain macrophages. Using CD133 as a marker of stemness, they enriched for or deprived the mouse glioma cell line GL261 of GSCs by fluorescence-activated cell sorting. [J Neuropathol Exp Neurol] Abstract Hypoxia Regulates Stemness of Breast Cancer MDA-MB-231 Cells The investigators cultured MDA-MB-231 cells in a hypoxic gas mixture to simulate the hypoxic environment in tissues and to determine how hypoxia conditions could affect the cell proliferation, apoptosis, cytotoxicity, and colony-forming ability.
