TOP STORY

TPO-Induced Metabolic Reprogramming Drives Liver Metastasis of Colorectal Cancer CD110⁺ Tumor-Initiating Cells
Scientists previously found that colorectal cancer tumor-initiating cells (TICs) expressing CD110, the thrombopoietin (TPO)-binding receptor, mediate liver metastasis. Here, they show that TPO promotes metastasis of CD110⁺ TICs to the liver by activating lysine degradation. [Cell Stem Cell]

PUBLICATIONS (Ranked by impact factor of the journal)

Targeting Phospholipase D1 Attenuates Intestinal Tumorigenesis by Controlling β-Catenin Signaling in Cancer-Initiating Cells
Researchers showed that genetic and pharmacological targeting of phospholipase D1 (PLD1) disrupts spontaneous and colitis-associated intestinal tumorigenesis in Apc^Min/+ and azoxymethane/dextran sodium sulfate mice models. PLD1 inactivation suppressed the self-renewal capacity of colon cancer-initiating cells by decreasing expression of β-catenin via E2F1-induced microRNA-4496 up-regulation. [J Exp Med] Abstract

Drug-Eluting Microarrays to Identify Effective Chemotherapeutic Combinations Targeting Patient-Derived Cancer Stem Cells
To address the challenge of screening drug libraries on patient-derived populations of rare cells, such as cancer stem cells, investigators developed a drug-eluting microarray, a miniaturized platform onto which a minimal quantity of cells can adhere and be exposed to unique treatment conditions. [Proc Natl Acad Sci USA]

Epigenetic Activation of TWIST1 by MTDH Promotes Cancer Stem-Like Cell Traits in Breast Cancer
Scientists report that metadherin (MTDH) drives cancer stem cell expansion by promoting the expression of TWIST1, a transcription factor critical for cancer cell stemness and metastasis. [Cancer Res] Abstract

IL6/JAK1/STAT3 Signaling Blockade in Endometrial Cancer Affects the ALDH^HICD126⁺-Like Component and Reduces Tumor Burden
Researchers hypothesized that high level of aldehyde dehydrogenase (ALDH) activity in a tumor might positively correlates with the presence of stem- and progenitor-like tumor cells in the disease setting of solid and hematopoietic cancers. [Cancer Res] Abstract | Full Article

Cytomegalovirus Infection Induces a Stem Cell Phenotype in Human Primary Glioblastoma Cells: Prognostic Significance and Biological Impact
Scientists investigated the relation between human cytomegalovirus (HCMV) infection of glioblastoma (GBM) cells and the presence of glioma cancer stem cells (GSCs). Infection of GBM cells with HCMV led to upregulation of CD133 and other GCS markers (Notch1, Sox2, Oct4, Nestin). [Cell Death Differ] Abstract

mPGES-1 in Prostate Cancer Controls Stemness and Amplifies EGFR-Driven Oncogenicity
Researchers investigated whether expression of intrinsic microsomal PGE synthase-1 (mPGES-1) enhanced aggressiveness of prostate cancer cells and might be critical for epidermal growth factor receptor (EGFR)-mediated tumor progression. DU145 and PC-3 cell lines expressing mPGES-1 expressed stem-cell-like features as well as mesenchymal transition markers. [Endocr-Relat Cancer] Abstract

Metabolic Stress Induces a Wnt-Dependent Cancer Stem Cell-Like State Transition
Scientists demonstrated that chronic metabolic stress in a long-term nutrient deprivation induces a Wnt-dependent phenoconversion of non-stem cancer cells toward stem-like state and this is reflected in the transcriptome analysis. [Cell Death Dis] Full Article

Identification of Thiostrepton as a Novel Therapeutic Agent that Targets Human Colon Cancer Stem Cells
The authors investigated thiostrepton’s inhibitory effects on the sphere- and colony-forming capabilities of colorectal cancer cell lines. The in vitro inhibition of sphere and colony formation was associated with downregulation of various modulators of the stem cell phenotype. [Cell Death Dis] Full Article

BMP-2 Induces Motility and Invasiveness by Promoting Colon Cancer Stemness through STAT3 Activation
Researchers investigated the role of bone morphogenetic proteins (BMP)-2 in colon cancer stem cell (CSC) development from colon cancer cells. They also determined the effects of BMP-2 on CSC development and epithelial-mesenchymal transition in human colon cancer cell lines HCT-116 and SW620. [Tumor Biol] Abstract

Cardamonin Induces Apoptosis by Suppressing STAT3 Signaling Pathway in Glioblastoma Stem Cells
Scientists investigated the effects of cardamonin (3,4,2,4-tetrahydroxychalcone) on the self-renewal and apoptosis of glioblastoma stem cells (GSCs), and if its action was associated with signal transducer and activator of transcription 3 (STAT3) pathway. [Tumor Biol] Abstract

REVIEWS

Stem vs Non-Stem Cell Origin of Colorectal Cancer
The current paradigm is that the intestinal stem cell is the origin of colorectal cancer (CRC). However, human histology and recent studies, showing marked plasticity within the intestinal epithelium, may point to other cells of origin. The authors review these latest studies and place these in context to provide an up-to-date view of the cell of origin of CRC. [Br J Cancer] Full Article

Effective Treatment of Glioblastoma Requires Crossing the Blood-Brain Barrier and Targeting Tumors including Cancer Stem Cells: The Promise of Nanomedicine
The authors examine the current nanomedicine approaches for targeting cancer stem cells (CSCs) and their therapeutic implications. The inhibitory effect of various nanoparticle-based drug delivery system towards CSCs in glioblastoma multiforme tumors is the primary focus of this review. [Biochem Biophys Res Commun] Abstract
