TOP STORYDrug Suppresses Spread of Breast Cancer Caused by Stem-Like Cells Scientists revealed that co-expression of cell surface receptor integrin αvβ3 and transcription factor Slug — a master regulator of a cell’s ability to self-renew and differentiate — identifies rare stem-like cells in patient-derived tumor samples that are associated with metastasis.

PUBLICATIONS(Ranked by impact factor of the journal)Breast Cancer Metastasis Suppressor OTUD1 Deubiquitinates SMAD7 Researchers report a loss-of-function screen in mice with metastasis as readout and identified OTU domain-containing protein 1 (OTUD1) as a metastasis-repressing factor. OTUD1-silenced cancer cells showed mesenchymal and stem-cell-like characteristics. [Nat Commun] Full Article SUV420H2 Is an Epigenetic Regulator of Epithelial/Mesenchymal States in Pancreatic Cancer Through its repressive mark H4K20me3, SUV420H2 silences several key drivers of the epithelial state. Its knockdown elicited mesenchymal-to-epithelial transition on a molecular and functional level, and cells displayed decreased stemness and increased drug sensitivity. [J Cell Biol] Full Article | Press Release Interferon-Beta Represses Cancer Stem Cell Properties in Triple-Negative Breast Cancer The authors found that repressed IFN signaling in triple-negative breast cancers (TNBCs) with CSC-like properties is due to high levels of IFN-stimulated gene factor 3 and that treatment with IFN-β reduces CSC properties, suggesting a therapeutic strategy to treat drug-resistant, highly aggressive TNBC tumors. [Proc Natl Acad Sci USA] Full Article Scientists performed in silico screening and in vitro validation studies through Western blotting, qRT-PCR for treatment of WNT and SHH signaling inhibitors, and BMP signaling inducer with control and inhibitor of differentiation 1 (ID1)-overexpressing cells. [Clin Cancer Res] Abstract | Full Article The authors investigated whether hyperglycemia promotes epithelial-mesenchymal-transition and CSC-features in premalignant and malignant pancreatic ductal epithelial cells. While hyperglycemia did not impact the mesenchymal phenotype of Panc1 cells, CSC-properties were aggravated exemplified by increased Nanog expression and Nanog-dependent formation of holo- and meroclones. [Cancer Lett] Abstract Using genetic and pharmacological approaches to stimulate or antagonize the transforming growth factor (TGF)-β pathway in human glioma-initiating cells, investigators observed that TGF-β exerts an inhibitory effect on c-MET phosphorylation. [Cell Death Dis] Full Article BCL-XLOverexpression Promotes Tumor Progression-Associated Properties BCL-XL overexpressing cells exhibited higher tumor sphere formation capacity and expressed higher levels of some stem cell markers, supporting the concept that BCL-XL plays essential roles in the maintenance of cancer stem cell phenotype. [Cell Death Dis] Full Article Loss of function assays revealed that knockdown of lncTCF7 significantly inhibited glioma cell migration, proliferation and tumorigenicity in vitro and in vivo. [Sci Rep] Full Article Inhibition of the Sonic hedgehog signaling pathway by GANT-61 induced apoptosis with more efficacy than by GDC-0449 in prostate cancer (PC) stem cells and PC cell lines.

REVIEWSTargeting Cancer Stem Cells and Signaling Pathways by Resveratrol and Pterostilbene In past decades, increasing evidence regarding CSCs may account for carcinogenesis, tumor drug-resistant, and metastasis. The authors focus on targeting signaling pathways of CSCs by natural resveratrol and its dimethylated derivative pterostilbene.
