    Tumor-Initiating Cells Establish an IL-33–TGF-β Niche Signaling Loop to Promote Cancer Progression

    The authors showed, using a mouse model of squamous cell carcinoma, that tumor-initiating cells played a crucial role in creating a niche microenvironment that was required for tumor progression and drug resistance.

    BMI1 Inhibition Eliminates Residual Cancer Stem Cells after PD1 Blockade and Activates Antitumor Immunity to Prevent Metastasis and Relapse

    Researchers showed that the combination treatment of anti-PD1 and cisplatin enriched BMI1+ CSCs in head and neck squamous cell carcinoma (HNSCC) while inhibiting HNSCC growth.

    LEFTY1 Is a Dual-SMAD Inhibitor that Promotes Mammary Progenitor Growth and Tumorigenesis

    Scientists showed that LEFTY1, a secreted inhibitor of NODAL/SMAD2 signaling, was produced by mammary progenitor cells and, concomitantly, suppressed SMAD2 and SMAD5 signaling to promote long-term proliferation of normal and malignant mammary epithelial cells.

    Therapeutic Inhibition of FcγRIIb Signaling Targets Leukemic Stem Cells in Chronic Myeloid Leukemia

    Investigators describe the immunoreceptor tyrosine-based inhibition motif-containing Fc gamma receptor IIb for being critical in leukemic stem cell resistance and showed that targeting FcγRIIb downstream signaling, by using a Food and Drug Administration-approved BTK inhibitor, provided a successful therapeutic approach.

    Abstract

    Inactivating p53 Is Essential for Nerve Growth Factor Receptor to Promote Melanoma-Initiating Cell-Stemmed Tumorigenesis

    Knockdown of nerve growth factor receptor (NGFR) markedly reduced the size and number of spheroid formation of melanoma cells, which could be rescued by ectopically expressed NGFR.
