Dll1+ Quiescent Tumor Stem Cells Drive Chemoresistance in Breast Cancer through NF-κB Survival Pathway

Using conditional knockout and reporter mouse models, the authors demonstrated that tumor cells expressing the Notch ligand Dll1 was important for tumor growth and metastasis and bear similarities to tumor-initiating cancer cells in breast cancer.

Autophagy Augments the Self-Renewal of Lung Cancer Stem Cells by the Degradation of Ubiquitinated p53

By generating stable human lung cancer stem cell (CSC) cell lines with the wild-type TP53, as well as cell lines in which TP53 was deleted, the authors showed, for the first time, that autophagy augments the stemness of lung CSCs by degrading ubiquitinated p53.

Adrenomedullin-CALCRL Axis Controls Relapse-Initiating Drug Tolerant Acute Myeloid Leukemia Cells

Calcitonin receptor-like receptor (CALCRL) knockdown impaired leukemic growth, decreased leukemic stem cell frequency, and sensitized to cytarabine in patient-derived xenograft models.

Decorin-Mediated Suppression of Tumorigenesis, Invasion, and Metastasis in Inflammatory Breast Cancer

Overexpression of decorin in inflammatory breast cancer (IBC) cells markedly decreased migration, invasion, and cancer stem cells in vitro and inhibited tumor growth and metastasis in IBC xenograft mouse models.

CD117/C-Kit Defines a Prostate CSC-Like Subpopulation Driving Progression and TKI Resistance

To determine how CD117 expression and activation by its ligand stem cell factor alters prostate cancer aggressiveness, researchers used C4-2 and PC3-mm human prostate cancer cells, which contained a CD117+ subpopulation.

Prolactin Receptor-Driven Combined Luminal and Epithelial Differentiation in Breast Cancer Restricts Plasticity, Stemness, Tumorigenesis and Metastasis

The authors found that interfering with expression of the receptor for the lactogenic hormone prolactin in breast cancer cells representative of the luminal and epithelial breast cancer subtypes resulted in loss of their differentiation state, enriched for stem-like cell subpopulations, and increased their tumorigenic capacity in a subtype-specific manner.

Interplay between Desmoglein2 and Hypoxia Controls Metastasis in Breast Cancer

Investigators found that high expression of desmoglein2, a component of desmosome-mediated intercellular adhesion complexes, promoted tumor growth, increased the prevalence of circulating tumor cell clusters, and facilitated distant organ colonization.

ADAMTS1 Supports Endothelial Plasticity of Glioblastoma Cells with Relevance for Glioma Progression

The authors performed an in silico study of ADAMTS1 and endothelial markers in human gliomas, providing the basis to further assess these molecules in several primary glioblastoma-initiating cells and established glioblastoma cells with the ability to acquire an endothelial-like phenotype.
