TOP STORY
IL-22+CD4+ T Cells Promote Colorectal Cancer Stemness via STAT3 Transcription Factor Activation and Induction of the Methyltransferase DOT1L
Interleukin-22 (IL-22) acted on cancer cells to promote activation of the transcription factor STAT3 and expression of the histone 3 lysine 79 methyltransferase DOT1L. The DOT1L complex induced the core stem cell genes NANOG, SOX2, and Pou5F1, resulting in increased cancer stemness and tumorigenic potential. [Immunity] Abstract

PUBLICATIONS (Ranked by impact factor of the journal)
A Nanoparticle Carrying the p53 Gene Targets Tumors including Cancer Stem Cells, Sensitizes Glioblastoma to Chemotherapy and Improves Survival
Researchers demonstrate that systemic nanodelivery platform crosses the blood brain barrier and efficiently targets glioblastoma multiforme, as well as cancer stem cells which have been implicated in recurrence and treatment resistance in many human cancers. [ACS Nano] Abstract

Clonal Variegation and Dynamic Competition of Leukemia-Initiating Cells in Infant Acute Lymphoblastic Leukemia with MLL Rearrangement
Through Ig/TCR rearrangement analysis of mixed lineage leukemia (MLL)-AF4+ infant acute lymphoblastic leukemia (ALL) at diagnosis and xenograft leukemias from mice transplanted with the same diagnostic samples, scientists established that MLL-AF4+ infant ALL is composed of a branching subclonal architecture already at diagnosis, frequently driven by a Ig/TCR-rearranged founder clone. [Leukemia] Abstract

The Cancer Stem Cell Marker Aldehyde Dehydrogenase Is Required to Maintain a Drug-Tolerant Tumor Cell Subpopulation
Investigators defined a requirement for the previously established cancer stem cell marker aldehyde dehydrogenase in the maintenance of this drug-tolerant subpopulation. [Cancer Res] Abstract

Chloroquine Eliminates Cancer Stem Cells through Deregulation of Jak2 and DNMT1
Researchers report that chloroquine sensitizes triple negative breast cancer cells to paclitaxel through inhibition of autophagy and reduces the CD44+/CD24-/low cancer stem cells population in both preclinical and clinical settings. [Stem Cells] Abstract

Anaplastic Large Cell Lymphoma-Propagating Cells Are Detectable by Side Population Analysis and Possess an Expression Profile Reflective of a Primitive Origin
Researchers showed that a small subset of cells purified from human anaplastic lymphoma kinase-positive and -negative, anaplastic large cell lymphoma cell lines and primary patient tumors using the side population technique have serial tumor-propagating capacity both in vitro and in vivo. [Oncogene] Abstract

Combined PDK1 and CHK1 Inhibition Is Required to Kill Glioblastoma Stem-Like Cells In Vitro and In Vivo
In order to decode the signal transduction networks responsible for the malignant properties of glioblastoma stem-like cells (GSCs), scientists analyzed a collection of GSC lines using a dual, but complementary, experimental approach, that is, reverse-phase protein microarrays and kinase inhibitor library screening. [Cell Death Dis] Full Article

The Role of Src Family Kinases in Growth and Migration of Glioma Stem Cells
Scientists examined the expression pattern of individual members of Src family kinases and their functional role in CD133+ glioma stem cells in comparison to primary glioma cells. [Int J Oncol] Abstract

Honokiol Suppresses Renal Cancer Cells’ Metastasis via Dual-Blocking Epithelial-Mesenchymal Transition and Cancer Stem Cell Properties through Modulating miR-141/ZEB2 Signaling
Researchers found that honokiol suppressed renal cancer cells’ metastasis via dual-blocking epithelial-mesenchymal transition and cancer stem cell properties. [Mol Cells] Abstract | Full Article

REVIEWS
Circulating Tumor Cells – A Bona Fide Cause of Metastatic Cancer
This review explores the evidence for circulating tumor cells (CTCs) in the initiation and progression of metastatic cancer and the data supporting these different concepts in an attempt to better understand the role of CTCs in metastasis. [Cancer Metastasis Rev] Abstract

Chemical Approaches to Targeting Drug Resistance in Cancer Stem Cells
The authors summarize the mechanisms underlying cancer stem cells (CSC) resistance, the potential biological targets to overcome resistance and the chemical compounds showing activity against different types of CSC. [Drug Discov Today] Abstract

Cancer Stem Cells: Biological Functions and Therapeutically Targeting
The authors discuss insights into cancer stem cells historical background and to provide a brief review of the new therapeutic strategies for targeting cancer stem cells. [Int J Mol Sci] Abstract | Download Full Article
