Curcumin Targets Breast Cancer Stem-Like Cells with Microtentacles that Persist in Mammospheres and Promote Attachment
Researchers report that breast cancer cell lines with more stem-like properties display higher levels of microtentacles, a type of tubulin-based protrusion of the plasma cell membrane which forms on detached or suspended cells and aid in cell reattachment. [Cancer Res] Abstract

PUBLICATIONS (Ranked by impact factor of the journal)
Tumor Suppressor Alterations Cooperate to Drive Aggressive Mesotheliomas with Enriched Cancer Stem Cells via a p53-miR34a-c-Met Axis
Scientists demonstrated that germline knockout of one allele of NF2 and CDKN2A causes accelerated onset and progression of asbestos-induced malignant mesothelioma compared to asbestos-exposed Nf2+/- or wild-type mice. [Cancer Res] Abstract

CD44 Expressed on Cancer-Associated Fibroblasts Is a Functional Molecule Supporting the Stemness and Drug Resistance of Malignant Cancer Cells in the Tumor Microenvironment
Scientists showed that cancer-associated fibroblasts (CAFs) support tumor growth in vivo and maintain the stemness of cancer stem/initiating cells in an in vitro model using an established CAF cell line. [Stem Cells]

Selective Non-Nucleoside Inhibitors of Human DNA Methyltransferases Active in Cancer Including Cancer Stem Cells
Through a process of hit-to-lead optimization, researchers report the discovery of compound 5 as potent non-nucleoside DNA methyltransferase inhibitors, and selective towards other AdoMet-dependent protein methyltransferases. [J Med Chem] Abstract

Elevated Intrinsic Cancer Stem Cell Population in Human Papillomavirus-Associated Head and Neck Squamous Cell Carcinoma
Because the prognoses of patients with human papillomavirus (HPV) 16-positive and HPV-negative head and neck squamous cell carcinoma are distinct, scientists sought to determine whether differences in the number of cancer stem cells could account for this clinical observation. [Cancer] Abstract

Progesterone Stimulates Progenitor Cells in Normal Human Breast and Breast Cancer Cells
Scientists showed that progesterone stimulates progenitor cells in human breast cancer cell lines and expands the cancer stem cell population via increasing the stem-like CD44+ population. [Breast Cancer Res Treat] Abstract

Syndecan-1 (CD138) Modulates Triple-Negative Breast Cancer Stem Cell Properties via Regulation of LRP-6 and IL-6-Mediated STAT3 Signaling
Investigators deciphered the functional impact of Syndecan-1 knockdown using RNA interference on the breast cancer stem cell phenotype of human triple-negative MDA-MB-231 and hormone receptor-positive MCF-7 cells in vitro employing an analytical flow cytometric approach. [PLoS One] Full Article

Constitutive Activation of STAT3 Signaling Regulates hTERT and Promotes Stem Cell-Like Traits in Human Breast Cancer Cells
Scientists demonstrated that STAT3 physically interacts with CD44 and NF-kB and activates the catalytic subunit of telomerase in human breast cancer stem cells. [PLoS One] Full Article

Studies on MicroRNAs that Are Correlated with the Cancer Stem Cells in Chronic Myeloid Leukemia
The authors aimed to detect the miRNAs that are correlated with the cancer stem cells in chronic myeloid leukemia (CML) to provide theoretical basis for clinical application. They first analyzed microRNA expression profiles of CML leukemia patients compared with normal controls by microarray analysis and validated the results by real-time PCR. [Mol Cell Biochem] Abstract

Identification of Novel Human Leukocyte Antigen-A*0201-Restricted, Cytotoxic T Lymphocyte Epitopes on CD133 for Cancer Stem Cell Immunotherapy
Autologous monocyte-derived dendritic cells pulsed with the CD133-405 or CD133-753 peptides generated cytotoxic T cells that efficiently recognized the CD133 epitopes presented in T2 HLA-A*0201 cells and specifically lysed CD133+ HLA-A*0201+ glioblastoma multiforme cancer stem cells.

Oncogenic Somatic Events in Tissue-Specific Stem Cells: A Role in Cancer Recurrence?
Emerging evidence suggests that tissue-specific stem cells (TSSCs) are implicated in malignancies, with several theories being proposed and tested, including many attempts to identify the cells of origin and studies deigned to understand how TSSCs participate in age-related increase in cancer risk. [Ageing Res Rev] Abstract

Kinase-Inhibitor-Insensitive Cancer Stem Cells in Chronic Myeloid Leukemia
This review focuses on the mechanisms of leukemic stem cells insensitivity to tyrosine kinase inhibitors and on the strategies to obtain synthetic lethality with combination therapies. [Exp Opin Biol Ther] Abstract

Stanford Shares in $540 Million Gift from Ludwig Cancer Research
The Stanford University School of Medicine has received $90 million from Ludwig Cancer Research on behalf of its founder, Daniel K. Ludwig, to support the school’s innovative work in cancer stem cells, which are believed to drive the growth of many cancers. [Stanford University] Press Release

Weill Cornell Medical College Receives $75 Million Gift from Sandra and Edward Meyer and the Sandra and Edward Meyer Foundation to Create the Meyer Cancer Center at Weill Cornell
Weill Cornell Medical College announced that it has received a $75 million gift from Sandra and Edward Meyer and the Sandra and Edward Meyer Foundation to expand and enhance the medical college’s distinguished cancer research and care programs. [Weill Cornell Medical College] Press Release
