    IGFBP5 Is an ROR1 Ligand Promoting Glioblastoma Invasion via ROR1/HER2-CREB Signaling Axis

    Researchers reported Insulin-like Growth Factor-Binding Protein 5 (IGFBP5), a ligand for Receptor tyrosine kinase-like Orphan Receptor 1 (ROR1), as a promising target for glioblastoma stem-like cell invasion.

    Cancer-Associated Fibroblast-Derived miR-146a-5p Generates a Niche That Promotes Bladder Cancer Stemness and Chemoresistance

    To better understand the mechanisms involved in tumor microenvironment-mediated generation and support of urothelial bladder cancer CSCs, scientists focused on the role of cancer-associated fibroblasts.

    SREBP2 Maintains Glioblastoma Stem Cells through Keeping the Balance between Cholesterol Biosynthesis and Uptake

    In vitro and in vivo loss-of-function genetic and pharmacologic assays were conducted to evaluate the effect of Sterol Regulatory Element-Binding Protein 2 (SREBP2) on glioblastoma cholesterol biosynthesis, proliferation, and self-renewal.


    Eliciting Effective Tumor Immunity against Ovarian Cancer by Cancer Stem Cell Vaccination

    Scientists evaluated the immune effects of CSCs vaccines on ovarian cancer (OC). The CD44+CD117+CSCs were isolated from human OC HO8910 and SKOV3 cells using the magnetic cell sorting system.

    Depleting DDX1 Sensitizes Non-Small Cell Lung Cancer Cells to Chemotherapy by Attenuating Cancer Stem Cell Traits

    The authors found that depleting DEAD-box helicase 1 (DDX1) increased the sensitivity of non-small cell lung cancer cells to the chemotherapy drug cisplatin, increased cell apoptosis, and inhibited cell migration and invasion.

    RHAMM Marks Proliferative Subpopulation of Human Colorectal Cancer Stem Cells

    Scientists investigated organoids, miniature forms of tumor tissues with reconstructing cellular diversity, to identify specific marker to characterize CSCs in heterogeneous tumors.

    Adipocytes Reprogram Prostate Cancer Stem Cell Machinery

    Researchers demonstrated that 3T3-L1 adipocyte conditioned media could endow PC3 and DU145 prostate cancer cells with stemness properties, by stimulating their sphere formation ability and promoting CD133 and CD44 expression.

    Deciphering the Molecular Mechanism of the THBS1 Gene in the TNF Signaling Axis in Glioma Stem Cells

    To investigate the relevant molecular mechanism and signal pathway of glioma stem cell behavior mediated by thrombospondin 1 (THBS1), U251 astroglioma cells and glioma stem cells were taken as model cells for in vitro experiments.

    The Roles and Molecular Mechanisms of Long Non-Coding RNA WT1-AS in the Maintenance and Development of Gastric Cancer Stem Cells

    The authors showed that long non-coding RNA WT1 antisense RNA (WT1-AS) negatively regulated Wilms’ tumor 1 (WT1) expression in gastric CSCs.
