    An Ellagic Acid Coordinated Copper-Based Nanoplatform for Efficiently Overcoming Cancer Chemoresistance by Cuproptosis and Synergistic Inhibition of Cancer Cell Stemness

    Ellagic acid inhibited stemness maintenance by suppressing the hedgehog pathway, while Cu2+ further decreased stemness features of tumor cells by disrupting mitochondrial metabolism, effectively enhancing doxorubicin-mediated chemotherapy.


    Targeting ABCA12-Controlled Ceramide Homeostasis Inhibits Breast Cancer Stem Cell Function and Chemoresistance

    Scientists developed a stem cell factor SOX9-based reporter for isolating CSCs in primary tumors and metastases of spontaneous mammary tumor models.

    RAB27B-Regulated Exosomes Mediate LSC Maintenance via Resistance to Senescence and Crosstalk with the Microenvironment

    Investigators found that increased RAB27B in leukemia stem cells prevented their senescence and maintained their stemness in vitro and in vivo.


    MiR-204 Suppresses Cancer Stemness and Enhances Osimertinib Sensitivity in Non-Small Cell Lung Cancer by Targeting CD44

    Scientists explored novel miRNA–mRNA regulatory mechanisms that contribute to osimertinib resistance in lung cancer. They found that miR-204 expression in osimertinib-resistant lung cancer cells was markedly reduced compared to that in osimertinib-sensitive parental cells.

    SIX1 Amplification Modulates Stemness and Tumorigenesis in Breast Cancer

    Researchers demonstrated that the expression of sine oculis homeobox homolog 1 (SIX1) varied among different subtypes of breast cancer and that it upregulated breast cancer grading and lymph node metastasis.

    METTL3 Facilitates Stemness Properties and Tumorigenicity of Cancer Stem Cells in Hepatocellular Carcinoma through the SOCS3/JAK2/STAT3 Signaling Pathway

    Loss- and gain-of-function experiments were utilized to assess the biological effects of METTL3 and SOCS3 on the proliferation and stemness phenotypes in vitro and in vivo.

    Periostin Facilitates Ovarian Cancer Recurrence by Enhancing Cancer Stemness

    Scientists examined how elevated extracellular periostin, as they found was present in recurrent ovarian cancer (OC), impacted OC cell functions and phenotypes, including stemness.

    Distinctive Mesenchymal-Like Neurofibroma Stem Cells Shape NF1 Clinical Phenotypes Controlled by BDNF Microenvironment

    Researchers determined the phenotypic and therapeutic relevance of tumor microenvironment in neurofibroma type I (NF1) patients. Tumor stem cells from NF1 were isolated and cultured using fluorescence-activated cell sorting and colony formation experiments.

    Cancer Stem Cells and Their Niche in Cancer Progression and Therapy

    The authors highlight the factors within the CSC niche that have important roles in regulating CSC properties, including the extracellular matrix, stromal cells, cancer-associated fibroblasts, mesenchymal stem cells, and physiological changes.
