TOP STORY

Intracellular Autofluorescence: A Biomarker for Epithelial Cancer Stem Cells
Researchers identified and characterized an intrinsic autofluorescent phenotype in cancer stem cells of diverse epithelial cancers and used this marker to isolate and characterize these cells. [Nat Methods]

PUBLICATIONS (Ranked by impact factor of the journal)

A Breast Cancer Stem Cell Niche Supported by Juxtacrine Signaling from Monocytes and Macrophages
Researchers show that tumor-associated monocytes and macrophages create a cancer stem cell (CSC) niche through juxtacrine signaling with CSCs. [Nat Cell Biol] Abstract

Sphingosine-1-Phosphate Promotes Expansion of Cancer Stem Cells via S1PR3 by a Ligand-Independent Notch Activation
Using microarray screening in aldehyde dehydrogenase (ALDH)-positive cancer stem cell (CSC) model, scientists identified a fundamental role for a lipid mediator sphingosine-1-phosphate (S1P) in CSC expansion. Stimulation with S1P enhanced ALDH-positive CSCs via S1P receptor 3 (S1PR3) and subsequent Notch activation. [Nat Commun] Abstract

Targeting Cancer Stem-Like Cells as an Approach to Defeating Cellular Heterogeneity in Ewing’s Sarcoma
Researchers assessed the effect of combining a drug that abrogates cancer stem-like cell (CSC) properties with standard-of-care therapy in a Ewing sarcoma family tumor (ESFT). Primary ESFT from four patients containing CD133⁺ CSC subpopulations ranging from 3-17% of total tumor cells were subjected to treatment with enoxacin, doxorubicin or both drugs. [Cancer Res] Abstract

p53 Protein Aggregation Promotes Platinum Resistance in Ovarian Cancer
Investigators demonstrate that in a unique population of high-grade serous ovarian carcinoma cancer cells with cancer stem cell properties, p53 protein aggregation is associated with p53 inactivation and platinum resistance. [Oncogene] Abstract

Annexin A3 as a Potential Target for Immunotherapy of Liver Cancer Stem-Like Cells
Overexpression of Annexin A3 (ANXA3) increased the proportion of CD133⁺ cells, enhancing their tumorigenicity. On the contrary, knockdown of ANXA3 decreased CD133⁺ cells and inhibited tumorigenicity. The mechanistic study revealed that ANXA3-mediated maintenance of hepatocellular carcinoma cancer stem-like cell/cancer initiating cell activity was likely involved with the HIF1A/Notch pathway. [Stem Cells] Abstract

Significance of Glioma-Associated Oncogene Homolog 1 (GLI1) Expression in Claudin-Low Breast Cancer and Crosstalk with the Nuclear Factor Kappa-Light-Chain-Enhancer of Activated B Cells (NFκB) Pathway
High GLI1 expression is a property of claudin-low cells and tumors and correlates with markers of epithelial to mesenchymal transition and breast cancer stem cells. Knockdown of GLI1 expression in claudin-low cell lines resulted in reduced cell viability, motility, clonogenicity, self-renewal, and reduced tumor growth of orthotopic xenografts.

Curcumin Suppresses Crosstalk between Colon Cancer Stem Cells and Stromal Fibroblasts in the Tumor Microenvironment: Potential Role of EMT
Scientists investigated the crosstalk between colorectal cancer cells with stromal fibroblasts and the anti-cancer effects of curcumin and 5-Fluorouracil, especially on cancer stem cell survival in a 3D-co-culture model that mimics in vivo tumor microenvironment. [PLoS One] Full Article

Cancer Stem-Like Sphere Cells Induced from De-Differentiated Hepatocellular Carcinoma-Derived Cell Lines Possess the Resistance to Anti-Cancer Drugs
Investigators induced cancer stem-like cells from hepatocellular carcinoma cell lines using a unique medium, and examined their potential for resistance to anti-cancer drugs. [BMC Cancer] Abstract | Full Article

REVIEWS

Emerging from the Shade of p53 Mutants: N-Terminally Truncated Variants of the p53 Family in EMT Signaling and Cancer Progression
The prevailing view has been that N-terminally truncated p53 family isoforms predominantly counteract cell cycle arrest and apoptosis. Molecular connections between N-terminally truncated p53 family isoforms and self-renewal have arisen, suggesting their potential function in the generation of cancer stem cells from bulk tumor cells. [Sci Signal] Abstract
