TOP STORYLnc-β-Catm Elicits EZH2-Dependent β-Catenin Stabilization and Sustains Liver CSC Self-Renewal Investigators found that long noncoding RNA (lncRNA)-β-Catm is required for self-renewal of liver cancer stem cells (CSCs) and tumor propagation in mice. lnc-β-Catm associates with β-catenin and the methyltransferase EZH2, thereby promoting β-catenin methylation.

PUBLICATIONS(Ranked by impact factor of the journal)Epithelial Cell Adhesion Molecule (EpCAM) is a Polycomb Repressive Complex 2-repressed gene, normally expressed in hepatic progenitors, but re-expressed in hepatic cancer stem cells. The authors investigated the functional significance of EpCAM re-expression in hepatitis B virus-mediated hepatocarcinogenesis. [J Hepatol] Abstract | Graphical Abstract Investigators analyzed the role of prion protein (PrPC) in glioblastoma (GBM) cell pathogenicity focusing on tumor-initiating cells, the subpopulation responsible for development, progression and recurrence of most malignancies. Analyzing four GBM cancer stem cell-enriched cultures, they showed that PrPC expression is directly correlated with the proliferation rate of the cells. [Oncotarget] Full Article Mesenchymal Stem Cell-Like Properties of CD133+ Glioblastoma Initiating Cells The present work sought to investigate the multipotent and mesenchymal properties of primary highly purified human CD133+ glioblastoma-initiating cells. [Oncotarget] Full Article Scientists investigate the mechanism of action responsible for the induction of apoptosis by disulfiram/copper and its effect on cancer stem cell properties in HER2-positive breast cancers in vitro and in vivo. [Cancer Lett] Abstract Stemness and Chemoresistance in Epithelial Ovarian Carcinoma Cells Under Shear Stress Researchers found that ovarian cancer cells significantly acquired the expression of epithelial-to-mesenchymal transition and cancer stem cells markers and a remarkable chemoresistance to clinically relevant doses of frontline chemotherapeutic drugs cisplatin and paclitaxel when grown under fluid shear stress, which corroborates with the physiological attainable levels in the malignant ascites, but not under static condition. [Sci Rep] Abstract To characterize the contributions of Dickkopf-1 towards the induction of vasculogenic mimicry in non-small cell lung cancer, the authors evaluated cohorts of primary tumors, performed in vitro functional studies and generated xenograft mouse models. [J Cell Mol Med] Full Article Notch4+ Cancer Stem-Like Cells Promote the Metastatic and Invasive Ability of Melanoma Sphere formation in conditioned serum-free culture medium supplemented with epidermal growth factor and basic fibroblast growth factor (tumorospheres) is considered useful for the enrichment of cancer stem-like cells, which are also known as tumor initiating cells. Researchers used an Agilent Gene Expression microarray to investigate the gene expression profile of melanoma cancer stem-like cells. [Cancer Sci] Abstract Selective Mode of Action of Plumbagin Through BRCA1 Deficient Breast Cancer Stem Cells Investigators confirmed that ALDH1 positivity is the best marker for the identification of breast cancer stem cells in BRCA1-defective breast cancer cell lines when compared to the CD marker profile and Side Population analysis.

REVIEWSCancer is now viewed as a stem cell disease. There is still no consensus on the metabolic characteristics of cancer stem cells, with several studies indicating that they are mainly glycolytic and others pointing instead to mitochondrial metabolism as their principal source of energy.
