Targeting PTPRK-RSPO3 Colon Tumors Promotes Differentiation and Loss of Stem-Cell Function Investigators showed that targeting RSPO3 in PTPRK-RSPO3-fusion-positive human tumor xenografts inhibits tumor growth and promotes differentiation. Notably, genes expressed in the stem-cell compartment of the intestine were among those most sensitive to anti-RSPO3 treatment. [Nature] Abstract NANOG Metabolically Reprograms Tumor-Initiating Stem-Like Cells through Tumorigenic Changes in Oxidative Phosphorylation and Fatty Acid Metabolism NANOG ChIP-seq analyses reveal that NANOG regulates the expression of genes involved in mitochondrial metabolic pathways required to maintain tumor-initiating stem-like cells. [Cell Metab] Abstract | Graphical Abstract | Press Release Cancer Stem Cell Regulation Changes at Late Stages of Skin Carcinoma Progression to Enhance Tumor Growth and Metastasis Using mouse models of skin squamous cell carcinoma (SCC) progression, investigators found that cancer stem cell regulatory mechanisms change in advanced SCCs, correlating with aggressive tumor growth and enhanced metastasis. [Cancer Res] Abstract Tumor Suppressor Control of the Cancer Stem Cell Niche To determine whether peroxisome proliferator activated receptor γ (PPARγ) regulates mammary stem cell expansion in mammary cancer, researchers deleted PPARγ expression in the mammary epithelium of an in vivo model of basal breast cancer. [Oncogene] Abstract Bulk Pancreatic Cancer Cells Can Convert into Cancer Stem Cells (CSCs) In Vitro and Two Compounds Can Target These CSCs Scientists investigated whether bulk pancreatic cancer cells could convert into CSCs under certain conditions and explored whether metformin and curcumin can kill pancreatic CSCs. [Cell Cycle] Abstract Mucin 1-Mediated Chemo-Resistance in Lung Cancer Cells Researchers demonstrated that non-small cell lung cancers (NSCLCs) survive paclitaxel (PTX) treatment. Compared with the progenitor NSCLC A549 cells, the PTX-resistant A549 cells displayed enhanced sphere-formation ability. [Oncogenesis] Full Article Inhibitory Effects of Metformin at Low Concentration on Epithelial-Mesenchymal Transition of CD44+CD117+ Ovarian Cancer Stem Cells The authors evaluated the effect of metformin at low dose on ovarian cancer stem cells in order to understand the underlying molecular mechanisms. [Stem Cell Res Ther] Full Article Role of HLA-G and Extracellular Vesicles in Renal Cancer Stem Cell-Induced Inhibition of Dendritic Cell Differentiation Researchers compared the ability of renal cancer stem cells and derived extracellular vesicles (EVs) to modulate the behavior of monocyte-derived dendritic cell with a non-tumor initiating renal cancer cell population and their EVs.
