    Preferential Iron Trafficking Characterizes Glioblastoma Stem-Like Cells
    Direct interrogation of iron uptake demonstrated that cancer stem-like cells (CSCs) potently extract iron from the microenvironment more effectively than other tumor cells. Systematic interrogation of iron flux determined that CSCs preferentially require transferrin receptor and ferritin, two core iron regulators, to propagate and form tumors in vivo.

    PUBLICATIONS (Ranked by impact factor of the journal)
    Adult Lineage-Restricted CNS Progenitors Specify Distinct Glioblastoma Subtypes
    Researchers examined the potential of adult lineage-restricted progenitors to induce fully penetrant glioblastoma multiforme using CNS progenitor-specific inducible Cre mice to mutate Nf1, Trp53, and Pten. [Cancer Cell] Abstract

    Genome-Wide Screen Identified let-7c/miR-99a/miR-125b Regulating Tumor Progression and Stem-Like Properties in Cholangiocarcinoma
    Researchers found that enforced expression of let-7c, microRNA (miR)-99a or miR-125b could reduce the activity of signal transducer and activator 3 and further suppress cholangiocarcinoma (CCA) tumorigenicity in vivo and inhibit the migration and invasion of CCA cells in vitro.

    ER-Stress-Induced Differentiation Sensitizes Colon Cancer Stem Cells to Chemotherapy
    Scientists report that ER-stress-induced activation of the unfolded protein response forces colon-cancer stem cells to differentiate, resulting in their enhanced sensitivity to chemotherapy in vitro and in vivo. [Cell Rep] Full Article | Graphical Abstract

    Functional and Molecular Characterization of Cancer Stem-Like Cells in Bladder Cancer: A Potential Signature for Muscle-Invasive Tumors
    The authors isolated and characterized bladder cancer stem cells making use of different functional and molecular approaches. The data obtained provide strong evidence that muscle-invasive bladder cancer is enriched with a heterogeneous stem-like population characterized by enhanced chemoresistance and tumor initiating properties, able to recapitulate the heterogeneity of the original tumor.

    PI3K/AKT/mTOR and Sonic Hedgehog Pathways Cooperate Together to Inhibit Human Pancreatic Cancer Stem Cell Characteristics and Tumor Growth
    Scientists examined the efficacy of combining NVP-LDE-225 and NVP-BEZ-235 on pancreatic cancer stem cells characteristics, microRNA regulatory network, and tumor growth. [Oncotarget] Full Article

    Obesity Promotes Colonic Stem Cell Expansion during Cancer Initiation
    Researchers assessed the effects of high fat feeding on colonic stem cell maintenance during cancer initiation and the responsiveness of stem cells to adipokine signaling pathways. [Cancer Lett] Abstract

    Clinical Influence of Cancer Stem Cells on Residual Disease after Preoperative Chemoradiotherapy for Rectal Cancer
    The authors evaluated the clinical influence of cancer stem cells on residual disease after preoperative chemoradiotherapy (CRT) in patients with rectal cancer. The surgical specimens of 145 patients with residual rectal cancer after preoperative CRT were assessed. [Tumor Biol] Abstract

    Ideal Sphere-Forming Culture Conditions to Maintain Pluripotency in a Hepatocellular Carcinoma Cell Lines
    Investigators identified and validated optimal culture conditions for sphere formation in hepatocellular carcinoma cells. Huh7 and HepG2 cells were plated in three different media types and were allowed to form spheres. [Cancer Cell Int] Full Article

    Targeting Colorectal Cancer Stem Cells Using Curcumin and Curcumin Analogs: Insights into the Mechanism of the Therapeutic Efficacy
    The authors highlight the efficacy of curcumin and its analogues in targeting colorectal cancer stem cell (CSC) and also the underlying molecular mechanism involved. Curcumin, in the presence or absence of other anti-cancer agents, has been shown to reduce the size of tumor mass and growth in both in vivo and in vitro studies by affecting many intracellular events that are associated with cancer progression and CSC formation.
