    Predicting Metastasis from Cues of Metastatic Cancer Stem-Like Cells-3D-Ultrasensitive Metasensor at a Single-Cell Level

    Scientists generated an ultrasensitive 3D-metasensor to efficiently capture and investigate metastatic CSCs and magnified the vital premetastatic signals from a single cell.

    High-Fat Diet-Activated Fatty Acid Oxidation Mediates Intestinal Stemness and Tumorigenicity

    The authors proposed that a high-fat diet enhanced intestinal stemness and tumorigenicity by engaging a peroxisome proliferator-activated receptor-fatty acid oxidation program.

    αSMA+ Fibroblasts Suppress Lgr5+ Cancer Stem Cells and Restrain Colorectal Cancer Progression

    Scientists demonstrated that αSMA+ cancer-associated fibroblast in colorectal cancer (CRC) exerted tumor-restraining functions via BMP4/TGFβ1 paracrine signaling that served to suppress Lgr5+ CSCs and promoted anti-tumor immunity, ultimately limiting CRC progression.

    Abstract

    RAL GTPases Mediate EGFR-Driven Intestinal Stem Cell Proliferation and Tumorigenesis

    In addition to impacting stem cell proliferation during damage-induced intestinal regeneration, the role of RAL GTPases impacted EGFR-dependent tumorigenic growth in the intestine and in the human mammary epithelium.

    Abstract

    The PI3K/mTOR Inhibitor Gedatolisib Eliminates Dormant Breast Cancer Cells in Organotypic Culture, but Fails to Prevent Metastasis in Preclinical Settings

    By probing a number of kinases downstream of integrin-β1, researchers determined that PI3K inhibition with either a tool compound or a compound in clinical trials robustly sensitized quiescent breast tumor cells seeded in organotypic bone marrow cultures to chemotherapy.

    Altered Lipid Metabolism Marks Glioblastoma Stem and Non-Stem Cells in Separate Tumor Niches

    Investigators interrogated gene expression in separate microenvironments of glioblastoma organoid models that mimicked the transition between nutrient-rich and nutrient-poor pseudopalisading/perinecrotic tumor zones using spatial-capture RNA-sequencing.

    Activation of Wnt Signaling Reduces the Population of Cancer Stem Cells in Ameloblastoma

    The authors identified a putative CSC population in immortalized and primary human ameloblastoma cells and examined possible therapeutic reagents to reduce the CSC population.

    Effects of the DRD2/3 Antagonist ONC201 and Radiation in Glioblastoma

    Investigators suggested that combined treatment with the DRD2/3 antagonist ONC201 and radiation improved the efficacy of radiation against glioblastoma (GBM) in vitro and in vivo through suppression of glioma-initiating cells without increasing toxicity in mouse models of GBM.

    RAD51AP1 Loss Attenuates Colorectal Cancer Stem Cell Renewal and Sensitizes to Chemotherapy

    Researchers provided in vivo evidence that RAD51-Associated Protein 1(RAD51AP1) played a critical role in colorectal cancer (CRC) growth and drug resistance by regulating CRC stem cell self-renewal.

    Abstract

    Identification of Cancer Cell Stemness-Associated Long Noncoding RNAs for Predicting Prognosis of Patients with Hepatocellular Carcinoma

    Cancer cell stemness-associated lncRNAs and their relevance in the prediction of clinical prognosis remain largely unexplored. Through the transcriptome-wide screen, scientists identified a total of 136 liver CSC-associated lncRNAs.

    Cancer Stem Cell–Immune Cell Crosstalk in Tumor Progression

    The authors discuss the signaling programs that simultaneously induce CSCs and reprogram the immune response to facilitate tumor immune evasion, metastasis, and recurrence.
    [Nature Reviews Cancer]

    Abstract

    Tissue Mechanics in Stem Cell Fate, Development, and Cancer

    Scientists review how dysregulation of tissue-level force increases the risk of malignancy, promotes tumor progression, and can induce a stem-like phenotype in tumor cells to drive tumor aggression and treatment resistance.
