TOP STORY
Activation of PI3K/Akt Pathway by CD133-p85 Interaction Promotes Tumorigenic Capacity of Glioma Stem Cells
Researchers demonstrated that the phosphorylation of tyrosine-828 residue in CD133 C-terminal cytoplasmic domain mediates direct interaction between CD133 and phosphoinositide 3-kinase (PI3K) 85 kDa regulatory subunit (p85), resulting in preferential activation of PI3K/protein kinase B (Akt) pathway in glioma stem cell relative to matched nonstem cell.

PUBLICATIONS (Ranked by impact factor of the journal)

MiR145 Targets the SOX9/ADAM17 Axis to Inhibit Tumor Initiating Cells and IL-6-Mediated Paracrine Effects in Head and Neck Cancer
Researchers report that ALDH1+CD44+ head and neck squamous cell carcinoma (HNC) cells express reduced levels of miR145. SPONGE-mediated inhibition of miR-145 was sufficient to drive tumor-initiating characteristics in non-tumor-initiating cells (TICs)/ ALDH1-CD44-negative HNC cells. [Cancer Res]

Inertial Focusing for Tumor Antigen-Dependent and -Independent Sorting of Rare Circulating Tumor Cells
Investigators described an inertial focusing-enhanced microfluidic circulating tumor cell (CTC) capture platform, termed “CTC-iChip,” that is capable of sorting rare CTCs from whole blood at 107 cells/s. [Sci Transl Med] Abstract | Press Release

Photochemical Internalization (PCI) of Immunotoxins Targeting CD133 Is Specific and Highly Potent at Femtomolar Levels in Cells with Cancer Stem Cell Properties
CD133 is a putative cancer stem cell marker for a number of different cancers and is suggested to be a therapeutic target. Researchers employed PCI, a minimally invasive method for light-controlled, specific delivery of membrane-impermeable macromolecules from endocytic vesicles to the cytosol, to specifically target CD133-positive cancer cells. [J Control Release] Abstract

TTC5 Is Required to Prevent Apoptosis of Acute Myeloid Leukemia Stem Cells
Using a screening strategy, researchers identified the tetratricopeptide repeat motif protein, Tetratricopeptide repeat domain 5 (TTC5) as required for the survival of human acute myeloid leukemia cells. [Cell Death Dis] Full Article

FK506 Binding Protein 51 Positively Regulates Melanoma Stemness and Metastatic Potential
Researchers hypothesized a role for FK506 binding protein 51 (FKBP51) in melanoma invasive behavior. Their study provides evidence that the genetic programs of cancer stemness and invasiveness overlap in melanoma, and that FKBP51 plays a pivotal role in sustaining such a program. [Cell Death Dis] Full Article

Proteomic Analysis Reveals that CD147/EMMPRIN Confers Chemoresistance in Cancer Stem Cell-Like Cells
Investigators presented a systematic analysis of the cell-surface proteome using a cancer stem cell-like cell line derived from MDA-MB453 breast cancer cells which exhibited a CD44+/CD24 phenotype and chemoresistance. [Proteomics] Abstract

Rapamycin Inhibits FBXW7 Loss-Induced Epithelial-Mesenchymal Transition and Cancer Stem Cell-Like Characteristics in Colorectal Cancer Cells
The authors explored whether FBXW7 plays any role in metastatic process. They showed that depletion of FBXW7 induces epithelial-mesenchymal transition in human colon cancer cells along with the increase in cell migration and invasion. Moreover, FBXW7 deficiency promotes the generation of colon cancer stem-like cells in tumor-sphere culture. [Biochem Biophys Res Commun] Abstract

NVP-LDE-225 (Erismodegib) Inhibits Epithelial-Mesenchymal Transition and Human Prostate Cancer Stem Cell Growth in NOD/SCID IL2Rγ Null Mice by Regulating Bmi-1 and MicroRNA-128
Scientists examined the molecular mechanisms, by which NVP-LDE-225/Erismodegib (smoothened inhibitor) regulates stem cell characteristics and tumor growth in prostate cancer. [Oncogenesis] Full Article
