    Single-Cell Analyses Define a Continuum of Cell State and Composition Changes in the Malignant Transformation of Polyps to Colorectal Cancer

    A large fraction of polyp and colorectal cancer (CRC) cells exhibited a stem-like phenotype, and investigators defined a continuum of epigenetic and transcriptional changes occurring in these stem-like cells as they progressed from homeostasis to CRC.

    Oct4A Palmitoylation Modulates Tumorigenicity and Stemness in Human Glioblastoma Cells

    The expression of Oct4 variants was evaluated in brain cancer cell lines, and in brain tumor tissues, by quantitative real-time PCR, western blotting, and immunohistochemical analysis.

    Abstract

    EZH2 Endorses Cell Plasticity to Non-Small Cell Lung Cancer Cells Facilitating Mesenchymal to Epithelial Transition and Tumor Colonization

    The authors found that besides its described role in CDKN2A-dependent cell proliferation, EZH2 upheld the epithelial state of cancer cells by repressing the transcription of hundreds of mesenchymal genes.

    Abstract

    Phenazine Derivatives Attenuate the Stemness of Breast Cancer Cells through Triggering Ferroptosis

    Scientists focused on the compounds without affecting cell viability and screened out three potential compounds that could significantly attenuate the stemness of breast cancer cells, as evident by the decrease of stemness marker expression.

    Abstract

    Exploring Stem Cell Biology in Pituitary Tumors and Derived Organoids

    In human pituitary tumors, cells typified by expression of stemness markers, in particular SOX2 and SOX9, were found present in a wide variety of clinical tumor types, also showing a pronounced proliferative status.

    Abstract

    The Presentation and Regulation of the IL-8 Network in the Epithelial Cancer Stem-Like Cell Niche in Patients with Colorectal Cancer

    Scientists characterized the presentation of CSCs and the interleukin-8 network in the adenoma/colorectal cancer epithelium using quantitative real-time PCR, immunohistochemistry, and double immunofluorescence.

    Abstract

    Essential Roles of TDO2 in Gastric Cancer: TDO2 Is Associated with Cancer Progression, Patient Survival, PD-L1 Expression, and Cancer Stem Cells

    Tryptophan 2,3-dioxygenase (TDO2) expression was correlated with both progressive disease and clinical outcome, and its expression was an independent predictor of prognosis in GC.
