    Nicotinamide
    Metabolism Mediates Resistance to Venetoclax in Relapsed Acute Myeloid Leukemia Stem Cells

    Detailed metabolomic analysis revealed elevated nicotinamide metabolism in relapsed leukemia stem cells (LSCs), which activated both amino acid metabolism and fatty acid oxidation to drive OXPHOS, thereby providing a means for LSCs to circumvent the cytotoxic effects of venetoclax and azacitidine therapy.

    β-Catenin and γ-Catenin Are Dispensable for T Lymphocytes and AML Leukemic Stem Cells

    In an MLL-AF9 AML mouse model, genetic deletion of β-catenin, or even all four Tcf/Lef family transcription factors that interact with β-catenin, did not affect AML onset in primary recipients, or the ability of leukemic stem cells in propagating AML in secondary recipients.

    Abstract

    E2F7−EZH2 Axis Regulates PTEN/AKT/mTOR Signaling and Glioblastoma Progression

    Functional studies showed that E2F7 promoted cell proliferation, cell-cycle progression, cell metastasis and tumorigenicity abilities in vitro and in vivo.

    Abstract

    The
    Different Role of YKL-40 in Glioblastoma Is a Function of MGMT Promoter Methylation Status

    The authors performed in vitro and in vivo experiments and six human IDH1/2 wild-type glioblastoma stem-like cells were established and studied to determine a potential interaction of YKL-40 and O6-methylguanine-DNA methyltransferase (MGMT) promoter methylation.

    D3 Signaling-Induced Decreases in IRX4 Inhibits NANOG-Mediated Cancer Stem-Like Properties and Gefitinib Resistance in NSCLC Cells

    Researchers discovered that increased iroquois-class homeodomain protein 4 (IRX4) was related to gefitinib resistance in non-small cell lung cancer (NSCLC) cells. Knockdown of IRX4 inhibited cell proliferation, sphere formation, and the expression of CD133, ALDH1A1, NANOG, Sox2 and Notch1, and the transcriptional activity of NANOG promoter.

    Exon-v6 from CD44v6-Containing Isoforms Influences Chemotherapy Response and Self-Renewal Capacity of Gastric Cancer Cells

    Investigators demonstrated that exon-v6 specific removal from CD44v isoforms increases cell sensitivity to cisplatin and impairs gastric cancer cells self-renewal.

    Adenovirus
    Infection Promotes the Formation of Glioma Stem Cells from Glioblastoma Cells through the TLR9/NEAT1/STAT3 Pathway

    Infection of patient-derived glioma cells with adenovirus (ADV) increased the formation of tumor spheres. ADV infection upregulated stem cell markers and in turn promoted the capacities of self-renewal and multi-lineage differentiation of the infected tumor spheres.

    Analysis
    of Circulating Breast Cancer Cell Heterogeneity and Interactions with Peripheral Blood Mononuclear Cells

    Scientists captured circulating tumor cells (CTCs) from the peripheral blood of breast cancer patients using size‐exclusion membranes followed by scRNA‐seq of enriched CTCs and carry‐over peripheral blood mononuclear cells.

    Characterization of Cancer Stem‐Cell Subpopulations in Oral Squamous Cell Carcinoma

    In vitro behavior of FACS‐sorted CD44HighESAHigh CSCs and CD44HighESALow CSCs from oral squamous cell carcinoma cells was characterized by their ability to form colonies, migrate, proliferate, and to invade a solid matrix.

    Leukemic
    Stem Cell Phenotype Is Associated with Mutational Profile in Acute Myeloid Leukemia

    The authors investigated the associations between genetic information and the various leukemic stem cell (LSC) phenotypes, namely multipotent progenitor-like, lymphoid primed multipotent progenitor-like and granulocyte-macrophage progenitors-like LSC in 52 acute myeloid leukemia patients.

    Effects
    of Photobiomodulation on Cellular Viability and Cancer Stem Cell Phenotype in Oral Squamous Cell Carcinoma

    Researchers evaluated in vitro, the effects of photobiomodulation (PBM), with the same dosimetric parameters as those used in the clinic for oral mucositis prevention and treatment, on oral squamous cell carcinoma cellular viability, as well as PBM’s effect on cancer stem cell properties and its phenotype.
