    Angiocrine Extracellular Vesicles Impose Mesenchymal Reprogramming upon Proneural Glioma Stem Cells

    Investigators document the secretory role of endothelial cells and their derived extracellular vesicles as drivers of proneural-to-mesenchymal reprogramming of glioma stem cells.

    SerpinB3 Drives Cancer Stem Cell Survival in Glioblastoma

    Knockdown of SerpinB3 increased apoptosis and susceptibility to radiation therapy, and scientists found that SerpinB3 was essential to buffer cathepsin L-mediated cell death.

    Snail Maintains the Stem/Progenitor State of Skin Epithelial Cells and Carcinomas through the Autocrine Effect of Matricellular Protein Mindin

    In models of cutaneous squamous cell carcinoma, investigators discovered a non-epithelial-mesenchymal transition function for the transcription factor Snail in maintaining the stemness of epidermal keratinocytes.

    Single-Cell Transcriptome Reveals Cellular Hierarchies and Guides P-EMT-Targeted Trial in Skull Base Chordoma

    Combining radiated UM-Chor1 RNA-seq data and in vitro validation, researchers found clusters of stem-like skull base chordoma cells were marked by cathepsin L, a gene involved in the packaging of telomere ends, and which may be responsible for radioresistance.

    CCR3 Blockage Elicits Polyploidization Associated with the Signatures of Epithelial-Mesenchymal Transition in Carcinoma Cell Lines

    The authors explored the blockage of chemokine receptor CCR3 in carcinoma cell lines and found that inhibition of CCR3 induced the formation of polyploid giant cells and stabilization of β-catenin via the PI3K/Akt/GSK-3β signaling pathway.

    Cancer Stem Cells Induced by Chronic Stimulation with Prostaglandin E2 Exhibited Constitutively Activated PI3K Axis

    Investigators assessed prostaglandin E2 (PGE2) as a candidate for incudcing CSCs from induced pluripotent stem cells (iPSCs), and chronic stimulation of the receptors EP-2/4 by PGE2 was supposed to induce CSCs from iPSCs through epigenetic effect.

    TWIST1 Induces Proteasomal Degradation of β-Catenin During the Differentiation of Ovarian Cancer Stem-Like Cells

    Researchers demonstrated that β-catenin is regulated by the protein degradation system in mesenchymal spheroid-forming cells and secondary epithelial ovarian cancer cells, but not in primary epithelial ovarian cancer cells.

    Intra-Tumor Heterogeneity of Cancer Stem Cell-Related Genes and Their Potential Regulatory MicroRNAs in Metastasizing Colorectal Carcinoma

    The expression gradient of four genes related to CSCs and their potential regulatory microRNAs were investigated in the central part and invasive front of the primary tumor, as well as in lymph node and liver metastases.

    An Anti-Alcoholism Drug, Disulfiram and Copper Complex Improves Radio-Resistance of Tumor-Initiating Cells in Esophageal Squamous Cell Carcinoma

    Scientists investigated the effect of disulfiram and copper (II) D-gluconate on the radiosensitivity of esophageal squamous cell carcinoma in xenograft mouse models.
