TOP STORYProtein C Receptor Is a Therapeutic Stem Cell Target in a Distinct Group of Breast Cancers Scientists showed that protein C receptor (Procr)+ cells were enriched for cancer stem cells in Wnt1 basal-like tumors, but not in Brca1 basal-like tumors or PyVT luminal tumors.

PUBLICATIONS(Ranked by impact factor of the journal)Single-Cell Transcriptomics Reveals Multi-Step Adaptations to Endocrine Therapy Researchers dissected the contributions of clonal genetic diversity and transcriptional plasticity during the early and late phases of endocrine therapy at single-cell resolution. [Nat Commun] Full Article The authors showed that miR-5188 exerted an oncogenic effect by inducing breast cancer stemness, proliferation, metastasis, and chemoresistance in vitro and in vivo. [Mol Ther] Abstract | Graphical Abstract The effects of microtubule targeting agents on regulators of TGF-β-induced epithelial-to-mesenchymal transition were evaluated in breast cancer cell lines using high content imaging, gene and protein expression, siRNA-mediated knockdown and chromatin immunoprecipitation. [Br J Cancer] Full Article Breast normal fibroblasts or cancer-associated fibroblasts were isolated from cancers by laser microdissection or were cultured. Fibroblasts were transfected to manipulate miR-222 or Lamin B receptor. The fibroblast-conditioned medium was collected and used to treat epithelial BC lines MDA-MB-231 and MDA-MB-157. [Br J Cancer] Abstract Investigators studied the early impact of trastuzumab on HER2 internalization and recycling in the HER2-overexpressing breast cancer cell line SKBR3. [Sci Rep] Full Article ADAM15 Mediates Upregulation of Claudin-1 Expression in Breast Cancer Cells Scientists created isogenic cell panels expressing five A disintegrin and metalloproteinase-15 (ADAM15) variants including wild-type and catalytically inactive forms. The expression of ADAM15 isoforms in MDA-MB-231 cells led to cell clustering to varying degree, without changes in EMT markers vimentin, slug and E-cadherin. [Sci Rep] Full Article Higher Glucose Enhances Breast Cancer Cell Aggressiveness Using lowly metastatic MCF-7 and highly metastatic MDA-MB231 breast cancer cells – highly incident cancer types – the authors established how glucose metabolism regulates actin and the biochemical changes that leads to alterations of cell mechanical properties. [Nutr Cancer] Abstract Researchers found that hepatocellular carcinoma up-regulated EZH2-associated long non-coding RNA (HEIH) was overexpressed in triple-negative breast cancer tissues and cell lines compared with adjacent normal mammary tissues and normal mammary epithelial cell line, respectively.

INDUSTRY NEWSRoche announced that the European Commission has approved Tecentriq® plus chemotherapy for the treatment of adult patients with unresectable locally advanced or metastatic triple-negative breast cancer whose tumors have PD-L1 expression and who have not received prior chemotherapy for metastatic disease. [F. Hoffmann-La Roche Ltd] Press Release Mary Kay Goes Global with Cancer Research Grant The Mary Kay Foundation announced that it is awarding its long-time partner UT Southwestern Medical Center a $500,000 global research grant for funding efforts to search for cures for breast, uterine, cervical and ovarian cancers.

POLICY NEWSWorld Health Organization Backs Open-Access Plan S The World Health Organization is joining cOAlition S, a growing group of agencies and charities that fund scientific research and that require their grantees to share their work in open-access journals or repositories. [The Scientist] Editorial A new White House directive laying out next year’s spending priorities for federal research agencies describes a US science enterprise imperiled by internal problems and foreign governments. [ScienceInsider] Editorial UK Science Minister Jo Johnson Resigns Amid Brexit Drama UK science minister Jo Johnson has resigned from his position as universities and science minister and as a member of the House of Commons, citing conflicts between what he thinks is best for the country and family ties.
