TOP STORYLoss of ANCO1 Repression at AIB1/YAP Targets Drives Breast Cancer Progression Researchers report that the expression of a subset of YAP-activated and YAP-repressed genes in normal mammary and early-stage breast cancer cells was dependent on the nuclear co-activator AIB1.

PUBLICATIONS(Ranked by impact factor of the journal)Plant Defensin PvD1 Modulates the Membrane Composition of Breast Tumor-Derived Exosomes Scientists studied the effect of the natural defensin from common bean, PvD1, on the formation of exosomes by breast cancer MCF-7 cells, mainly the modulatory effect it has on the level of CD63 and CD9 tetraspanins. [Nanoscale] Full Article | Graphical Abstract Cross-Talk between SIM2s and NFκB Regulates Cyclooxygenase 2 Expression in Breast Cancer For in vitro experiments, reporter luciferase assays were utilized in MCF7 cells to investigate promoter activity of nuclear factor kappa b (NFκB) and Singleminded-2 (SIM2s). Real-time PCR, immunoblotting, immunohistochemistry, and chromatin immunoprecipitation assays were performed in SUM159 and MCF7 cells. [Breast Cancer Res] Full Article The authors investigated the role and underlying mechanism of BCLIN25 in the regulation of ERBB2 expression. The transcriptional landscape across five subtypes of breast cancer was investigated using RNA sequencing. Integrative transcriptomic analysis was performed to identify the landscape of novel lincRNAs. [Cell Death Dis] Full Article Scientists performed mRNA-seq to compare gene expression profiles of various colorectal and mammary cell lines upon siRNA-mediated knockdown of USP22. All cell lines displayed a common reduction in the expression of Heat Shock Protein 90 Alpha Family Class B Member 1 (HSP90AB1). [Cell Death Dis] Full Article The cell lines Hs 578T, MDA-MB-468 and HCC1806, representing claudin-low, basal-like 1 and 2 triple-negative breast cancer molecular subtypes respectively, were engineered to express estrogen receptor beta under the control of a Tetracycline-inducible promoter and used to investigate the effects of this transcription factor on gene activity. [Proteomics] Abstract Investigators examined the efficacy of lactones in breast cancer preclinical model. Isodeoxyelephantopin (IDET) was relatively effective in comparison to DET. IDET suppressed the proliferation of both invasive and non-invasive breast cancer cell lines. [Sci Rep] Full Article The migration of cells was assessed by wound healing assay, and invasion ability was assessed by Matrigel invasion assay. Levels of MMP2 and MMP9 were measured by PCR. Akt, phospho-Akt, phospho-NF-κB p65 and NF-κB p65 were measured by western blotting. [BMC Cancer] Full Article Scientists evaluated the levels and possible associations of seven parameters including the status of the topoisomerase I (TOP1) gene, TOP1 protein expression level, TOP1 activity and camptothecin (CPT) susceptibility, the cellular CPT response and the cellular growth rate across a representative panel of breast cancer cell lines. [BMC Cancer] Full Article MCF7 cells were transfected with RasG12V/T35S plasmid, and H2B phosphorylation at serine 14 (H2BS14ph), ERK1/2, Mst1, and MDM2 expression were evaluated through executing western blot.

POLICY NEWSChinese Universities with Military Ties Classed as ‘Risky’ Collaborators Forty-three Chinese universities should be considered ‘very high’ or ‘high’ risk collaborators because of their involvement in research for military and defence purposes, according to an Australian think tank. [Nature News] Editorial Crack Down on Genomic Surveillance Concerns about the potential downsides of governments being able to interrogate people’s DNA have been voiced since the early 2000s by activist groups, such as the non-profit organization GeneWatch UK, and some geneticists.
