    Ectopic Lymphoid Structures Function as Microniches for Tumor Progenitor Cells in Hepatocellular Carcinoma
    Researchers studied an hepatocellular carcinoma mouse model that displayed abundant ectopic lymphoid-like structures and found that they constituted immunopathological microniches wherein malignant hepatocyte progenitor cells appeared and thrived in a complex cellular and cytokine milieu until gaining self-sufficiency. [Nat Immunol] Abstract

    PUBLICATIONS (Ranked by impact factor of the journal)
    IRAK1 Is a Therapeutic Target that Drives Breast Cancer Metastasis and Resistance to Paclitaxel
    Paclitaxel treatment induced strong interleukin-1 receptor-associated kinase 1 (IRAK1) phosphorylation, an increase in inflammatory cytokine expression, enrichment of cancer stem cells and acquired resistance to paclitaxel treatment. [Nat Commun] Full Article

    Targeting Cancer Stem Cell in Castration Resistant Prostate Cancer
    Scientists demonstrated immortalized normal human prostate epithelial cells, which appeared non-tumorigenic in vivo, become tumorigenic and acquired a stem cell phenotype after knocking down a tumor suppressor gene. [Clin Cancer Res] Abstract

    FOXC1 Activates Smoothened-Independent Hedgehog Signaling in Basal-Like Breast Cancer
    Scientists demonstrated that FOXC1 controls cancer stem cell (CSC) properties enriched in basal-like breast cancer cells via activation of Smoothened-independent Hedgehog (Hh) signaling. This non-canonical activation of Hh is specifically mediated by Gli2. [Cell Rep] Full Article | Graphical Abstract

    Cardamonin Reduces Chemotherapy-Enriched Breast Cancer Stem-Like Cells In Vitro and In Vivo
    Investigators demonstrated that cardamonin, a small molecule, selectively inhibits breast cancer stem cells (CSCs) that have been enriched by chemotherapeutic drugs. In addition, cardamonin also sufficiently prevents the enrichment of CSCs when simultaneously used with chemotherapeutic drugs. [Oncotarget] Full Article

    miRNA-Regulated Delivery of lincRNA-p21 Suppresses β-Catenin Signaling and Tumorigenicity of Colorectal Cancer Stem Cells
    The authors report that large intergenic non-coding RNA p21 (lincRNA-p21) is a potent suppressor of stem-like traits of cancer stem cells purified from both primary colorectal cancer tissues and cell lines. [Oncotarget] Full Article

    Overshoot during Phenotypic Switching of Cancer Cell Populations
    Investigators sorted human melanoma cells using three distinct cancer stem cell (CSC) markers — CXCR6, CD271 and ABCG2 — and observed that the fraction of non-CSC-marked cells first overshoots to a higher level and then returns to the level of unsorted cells. [Sci Rep] Full Article

    The Role of miR-145 in Stem Cell Characteristics of Human Laryngeal Squamous Cell Carcinoma Hep-2 Cells
    Researchers explored the role of miR-145, which is downregulated in laryngeal squamous cell carcinoma, on cancer stem cell potency of laryngeal cancer cells. They showed the downregulation of miR-145 expression in tumor tissue samples and in CD133-enriched cancer stem-like cells. [Tumor Biol] Abstract

    Enhanced G2/M Arrest, Caspase Related Apoptosis and Reduced E-Cadherin Dependent Intercellular Adhesion by Trabectedin in Prostate Cancer Stem Cells
    Investigators studied the effect of trabectedin in cell proliferation, cell cycle progression, apoptosis and spheroid formation in prostate cancer stem cells. [PLoS One] Full Article

    Functional Studies of miR-130a on the Inhibitory Pathways of Apoptosis in Patients with Chronic Myeloid Leukemia
    Scientists investigated the function of miR130a in p53 tumor suppressor signaling pathway. They performed microRNA expression profile analysis in chronic myeloid leukemia cancer stem cells of 38 cases and extracted total RNA from peripheral blood of 143 cases. [Cancer Gene Ther] Abstract

    Cancer Stem Cell Targeted Therapy: Progress amid Controversies
    The current status and progresses of cancer stem cells theory is illustrated and by providing a panoramic view of cancer therapy, the authors address the recent controversies regarding the feasibility of cancer stem cells targeted anti-cancer therapy. [Oncotarget] Full Article

    $20 Million Commonwealth Foundation for Cancer Research Gift to Expand Collaborative Cancer Research
    The Commonwealth Foundation for Cancer Research has pledged $20 million to the Bridge Project, a collaborative research program of the Koch Institute for Integrative Cancer Research at MIT and the Dana-Farber/Harvard Cancer Center, to accelerate the translation of interdisciplinary cancer solutions toward the clinic. [Massachusetts Institute of Technology] Press Release

    SCRA Technology Ventures Company Kiyatec Awarded $1.725 Million to Advance Cancer STEM Cell Expansion
    SCRA Technology Ventures’ SC Launch company KIYATEC announced an award of a Fast Track Phase I and Phase II Small Business Innovation Research contract for $1.725M from the National Cancer Institute. The overall goal of the contract is to develop culture systems which can grow and maintain the rare population of malignant cells referred to by some as cancer stem cells, which are believed to lead to therapy resistance, relapse and death from metastatic disease.
