PUBLICATIONS(Ranked by impact factor of the journal)Autophagy-related gene 7 (ATG7) facilitated the transcription of OCT4 via β-catenin which binds to the OCT4 promoter, promoting CSC characteristics in prostate cancer, including self-renewal, tumor initiation and drug resistance. [Clin Cancer Res] Abstract Investigators demonstrated that KG1a, a stem-like acute myeloid leukemia (AML) cell line that is resistant to double negative T cells (DNTs) and chemotherapy, and chemotherapy-resistant primary AML samples both became more susceptible to DNT-mediated cytotoxicity in vitro following pre-treatment with daunorubicin. [J Exp Clin Cancer Res] Full Article Scientists showed that TLR4 is a key factor to promote NFκB activation in differentiating glioblastoma stem-like cells (GSCs). TLR4 was upregulated during differentiation of GSCs and promoted transcriptional activation of NFκB as determined by luciferase-reporter assays and expression of NFκB target genes. [Sci Rep] Full Article The authors observed tumor formation in transcriptional coactivator with the PDZ-binding motif (TAZ) transgenic mice after administration of the carcinogen 7,12-dimethylbenzanthracene and demonstrated that tumorigenesis was reliant on the presence of TAZ. [Sci Rep] Full Article Upregulation of SALL4 by EGFR Activation Regulates the Stemness of CD44-Positive Lung Cancer Investigators report that the expression of sal-like protein 4 (SALL4), was significantly higher in EGFR mutated lung tumors than in non-tumor tissue. The knockdown of SALL4 expression could suppress spheroid formation and the expression of lung cancer stem cell marker CD44. [Oncogenesis] Full Article Isoharringtonine Inhibits Breast Cancer Stem-Like Properties and STAT3 Signaling Researchers showed that isoharringtonine (IHT) inhibited the proliferation of HCC1806, HCC1937, and MCF-7 cells, and suppressed the migration of HCC1806 and HCC1937 cells in a dose-dependent manner. IHT treatment decreased the proportion of breast CSCs in MCF-7, HCC1806, and HCC1937 cells. [Biomed Pharmacother] Abstract Melatonin Inhibits Osteosarcoma Stem Cells by Suppressing SOX9-Mediated Signaling Scientists demonstrated that melatonin potently suppresses the migration and invasion of osteosarcoma cells. Melatonin significantly inhibited the sarcosphere formation of osteosarcoma stem cells and regulated EMT markers of osteosarcoma cells. [Life Sci] Abstract Identification of Human Cutaneous Basal Cell Carcinoma Cancer Stem Cells Using a novel, reproducible in vivo xenograft growth assay, the authors determined that tumor-initiating cell frequencies are approximately 1 per 1.5 million unsorted basal cell carcinoma cells.

REVIEWSThe Ribosome, (Slow) Beating Heart of Cancer (Stem) Cell Scientists weigh the arguments supporting the existence of an ‘oncogenic’ ribosome and evaluate its role in cancer evolution. In particular, they provide an analysis and perspective on how the ribosome may play a critical role in the acquisition and maintenance of cancer stem cell phenotype.

INDUSTRY NEWSSTEMCELL Technologies Announces $45 Million Government Funding for Advanced Manufacturing Facility STEMCELL Technologies announced a $45 million joint funding agreement between the Governments of Canada and British Columbia to help the company build a state-of-the-art advanced manufacturing facility. The funding agreement will accelerate the Vancouver company’s rapidly scaling business of providing cutting-edge reagents and tools to support life science researchers around the world working in the cell therapy and regenerative medicine fields. [STEMCELL Technologies Inc.] Press Release Lin BioScience announced that the FDA has granted Orphan Drug Designation to LBS-007 for acute lymphoblastic leukemia. [Lin BioScience Inc.] Press Release Astellas Pharma Inc. announced that it submitted a new drug application for marketing approval of gilteritinib in Japan for the treatment of adult patients with FLT3 mutation-positive (FLT3mut+) relapsed or refractory acute myeloid leukemia. [Astellas Pharma Inc.] Press Release Boston Biomedical, Inc. announced that it has initiated dosing of the first patient in each of two clinical studies evaluating DSP-7888, an investigational cancer peptide vaccine. One study is in combination with checkpoint inhibitors for multiple tumor types, and the other is in combination with bevacizumab in glioblastoma. [Boston Biomedical, Inc.] Press Release | |

POLICY NEWSU.K. Commits to EU Trial Rules Post-Brexit as CRUK Hails ‘Fantastic News’ The U.K. government said it will endeavor to keep pace with the European Union’s impending changes in clinical trial procedures, bringing some solace to those wondering how the two will stay aligned after Brexit starts in earnest next March. [Questex LLC.] Editorial Rent Increase Hits Europe’s Drug Regulator before Brexit Move With less than a year to go before the European Medicines Agency must leave its London headquarters because of Brexit, the agency is facing an unexpected rent increase that could cut into its budget for approving new medicines and overseeing clinical trials. [Nature News] Editorial Scientists’ Early Grant Success Fuels Further Funding Young researchers who narrowly miss out on postdoctoral grant struggle to compete with those who just qualify.
