TOP STORYSuppressing Repair Protein Could Be Key to Treating Brain Tumors Targeting a specific DNA-repairing protein in the brain could be an effective way to treat the most aggressive type of brain tumor, a study suggests. Researchers at the University of Leeds found that inhibiting this protein, called RAD51, helped increase the effectiveness of radiotherapy in killing off glioblastoma cells in the lab.

PUBLICATIONS(Ranked by impact factor of the journal)Cyclooxygenase-2 Regulates TGFβ-Induced Cancer Stemness in Triple-Negative Breast Cancer The authors investigated the role of the cyclooxygenase-2 (COX-2), a downstream target of TGFβ, in regulating breast cancer stem cells in triple negative breast cancer (TNBC). Bioinformatics analysis revealed that COX-2 is highly expressed in TNBC and that its expression correlated with poor survival outcome in basal subtype of breast cancer. [Sci Rep] Full Article Motility of Glioblastoma Cells Is Driven by Netrin-1 Induced Gain of Stemness Scientists investigated the effects of netrin-1 on glioblastoma pathogenesis and glioblastoma cell stemness. Netrin-1 activated Notch signaling in glioblastoma cells resulting in subsequent gain of stemness and enhanced invasiveness of these cells. [J Exp Clin Cancer Res] Full Article The objective of this study was to investigate the usefulness of sulforaphane (SFN)–a constituent of cruciferous vegetables with a multitargeted effect–as a therapeutic agent for glioblastoma (GBM). SFN robustly inhibited the growth of GBM cell–induced cell death in established cell cultures and early-passage primary cultures and, most importantly, was effective in eliminating GBM stem cells, which play a major role in drug resistance and disease recurrence. [J Neurosurg] Abstract The functional association of gastric cancer stem cell markers with stemness and epithelial-mesenchymal transition (EMT) signature genes is unclear. Using gene-specific primers, researchers found that the NANOG expression primarily originates from the retrogene NANOGP8. LGR5 over-expression significantly enhanced sphere cell growth, cell proliferation, cell migration and drug resistance in MGC803 cells. [PLoS One] Full Article Camptothecin-induced apoptosis and necrosis in cancer stem cells with and without siCLU treatment were simultaneously measured using Qdot-based total internal reflection fluorescence microscope. [Cell Biol Toxicol] Abstract To improve the anticancer effects of gemcitabine, the authors investigated the molecular mechanism of KMC07 cells’ resistance to gemcitabine. They demonstrated constitutive activation of the Kras-MEK matrix metalloproteinase-10 signaling pathway in KMC07 cells that was enhanced by gemcitabine through histone acetylation. [Pancreas] Abstract The inhibition of the multiple myeloma CD138−CD34− cancer stem cell growth was investigated in non-obese-diabetic/severe-combined-immunodeficiency mice that were implanted with multiple myeloma RPMI 8226 cancer stem cells and treated with the LCL-HHT-H-PEG. [Exp Biol Med (Maywood)] Abstract Investigators demonstrated that miR-134-3p can directly decrease RAB27a expression. Furthermore, overexpression of miR-134-3p can effectively inhibit the proliferation, invasion and tumorigenicity of human ovarian cancer stem cells in vivo and in vitro. [Gene] Abstract Neurons Generated from Carcinoma Stem Cells Support Cancer Progression Scientists showed that a fraction of cancer stem cells derived from patients with gastric carcinoma and colorectal carcinoma are capable of producing neurons that are involved in tumor neurogenesis and tumor growth.

POLICY NEWSCleveland Clinic Will Discipline Doctor Who Wrote Antivaccination Column The Cleveland Clinic released an apology from a staff physician who published an antivaccination column on the news website Cleveland.com. The doctor, Daniel Neides, will be “appropriately disciplined,” the Ohio hospital added in its own statement, which noted that the family physician’s views do not reflect his institution’s.
