    PI3Kγ Maintains the Self-Renewal of Acute Myeloid Leukemia Stem Cells by Regulating the Pentose Phosphate Pathway

    Scientists found that while PI3Kγ was highly enriched in leukemia stem cells and critical for self-renewal, it was dispensable for normal hematopoietic stem cells.

    An NFAT1-C3a-C3aR Positive Feedback Loop in Tumor-Associated Macrophages Promotes a Glioma Stem Cell Malignant Phenotype

    The authors showed that the antitumor immune microenvironment was activated in glioma in Nfat1−/− mice, suggesting induction of the immune-suppressive microenvironment by nuclear factor of activated T cells-1 (NFAT1).

    Fbxw7 Suppresses Carcinogenesis and Stemness in Triple-Negative Breast Cancer through CHD4 Degradation and Wnt/β-Catenin Pathway Inhibition

    Researchers detected F-box and WD repeat domain-containing 7 (FBXW7) by immunohistochemistry in 80 triple-negative breast cancer patients. FBXW7 knockdown and overexpression in MD-MBA-231 and HCC1937 cell models were constructed.

    Inhibition of Proprotein Convertases Activity Results in Repressed Stemness and Invasiveness of Cancer Stem Cells in Gastric Cancer

    The general proprotein convertases (PCs) inhibitor, decanoyl-RVKR-chloromethyl-ketone, was used to repress PCs activity in CSCs of various gastric cancer cell lines.

    Role of Catecholamine Synthases in the Maintenance of Cancer Stem-Like Cells in Malignant Peripheral Nerve Sheath Tumors

    Scientists found that malignant peripheral nerve sheath tumors cells expressed catecholamine synthases and that these enzymes were essential for maintaining cancer stemness, such as the ability to self-renew and maintain an undifferentiated state.

    The m6A Methyltransferase RBM15 Affects Tumor Cell Stemness and Progression of Cervical Cancer by Regulating the Stability of lncRNA HEIH

    The TCGA database was used to screen differentially expressed m6A genes in normal and tumor tissues. QRT-PCR was used to quantify HEIH, miR-802, EGFR, cell stemness, and epithelial-mesenchymal transition-related genes.
