Disruption of β-Catenin-Mediated Negative Feedback Reinforces cAMP-Induced Neuronal Differentiation in Glioma Stem Cells

[Cell Death & Disease] Scientists demonstrated that cAMP triggered neuronal differentiation and compromised the self-renewal capacity in glioma stem cells.

GSK3β Palmitoylation Mediated by ZDHHC4 Promotes Tumorigenicity of Glioblastoma Stem Cells in Temozolomide-Resistant Glioblastoma through the EZH2–STAT3 Axis

[Oncogenesis] Researchers found that GSK3β was noted as a substrate for ZDHHC4-mediated palmitoylation at the Cys14 residue, which enhanced glioblastoma temozolomide resistance and glioblastoma stem cell self-renewal.

ΔNp63α Mediates Sulforaphane Suppressed Colorectal Cancer Stem Cell Properties through Transcriptional Regulation of Nanog/Oct4/Sox2

[Journal of Nutritional Biochemistry] Scientists showed that ΔNp63α expression was enhanced in sphere-forming colorectal cancer cells.

Identification of Two Cancer Stem Cell-Like Populations in Triple-Negative Breast Cancer Xenografts

[Disease Models & Mechanisms] The multiple-microtissue transcriptome analysis revealed three cancer cell-type clusters in the primary tumor and axillary lymph node metastasis, two of which were CSC-like clusters.

GM-CSF-miRNA-Jak2/Stat3 Signaling Mediates Chemotherapy-Induced Cancer Cell Stemness in Gastric Cancer

[Frontiers in Pharmacology] Researchers treated two human gastric cancer cell lines SGC7901 and BGC823 with 5-Fluorouracil or Cisplatin in vitro.

Recombinant Expression a Novel Fibronectin—Collage Fusion Peptide Modulating Stem Cell Stemness via Integrin β3

[Applied Microbiology and Biotechnology] A novel recombinant protein fibronectin-collagen peptide was designed to modulate the function of extracellular matrix expressed by Picha. pastoris strain X33.

BET Inhibitors Rescue Anti-PD1 Resistance by Enhancing TCF7 Accessibility in Leukemia-Derived Terminally Exhausted CD8+ T Cells

[Leukemia] Ex vivo treatment of cells from acute myeloid leukemia (AML) mice and AML patients with bromodomain and extra-terminal domain (BET) inhibitors reversed CD8+ T cell exhaustion by restoring proliferative capacity and expansion of the more functional precursor-exhausted T cells.

IFNγ Signaling in Cytotoxic T Cells Restricts Anti-tumor Responses by Inhibiting the Maintenance and Diversity of Intra-Tumoral Stem-Like T Cells

[Nature Communications] The authors reported that specific deletion of IFNγR in CD8 T cells promoted tumor control in a mouse model of melanoma, and provide evidence of a negative feedback loop whereby IFNγ depletes stem-like T cells to restrict anti-tumor immunity.

YTHDF2 Orchestrates Tumor-Associated Macrophage Reprogramming and Controls Antitumor Immunity through CD8+ T Cells

[Nature Immunology] Selectively targeting YTHDF2 in tumor-associated macrophages (TAMs) using a Toll-like receptor 9 agonist-conjugated small interfering RNA reprogrammed TAMs toward an antitumoral phenotype, restrained tumor growth, and enhanced the efficacy of PD-L1 antibody therapy.
