    Compromised Nuclear Envelope Integrity Drives TREX1-Dependent DNA Damage and Tumor Cell Invasion

    Scientists showed that nuclear envelope ruptures induced DNA damage that promoted senescence in non-transformed cells and induced an invasive phenotype in human breast cancer cells.

    Genetic Variations of DNA Bindings of FOXA1 and Co-Factors in Breast Cancer Susceptibility

    Researchers developed a statistical framework to analyze extensive ChIP-seq and GWAS data, identified 22 breast cancer risk-associated transcription factors (TFs), and showed that FOXA1 and co-factors formed a core TF-transcriptional network regulating the susceptibility genes.

    Abstract

    RASSF1C Oncogene Elicits Amoeboid Invasion, Cancer Stemness, and Extracellular Vesicle Release via a SRC/Rho Axis

    Investigators showed that the novel oncogene RASSF1C drove mesenchymal-to-amoeboid transition and stem cell attributed in breast cancer cells. Mechanistically, RASSF1C activated Rho/ROCK via SRC-mediated RhoGDI inhibition, resulting in generation of actomyosin contractility.

    Recurrence Biomarkers of Triple Negative Breast Cancer Treated with Neoadjuvant Chemotherapy and Anti-EGFR Antibodies

    To find metastatic recurrence biomarkers of TNBC treated by neoadjuvant chemotherapy and anti-EGFR antibodies, investigators evaluated tumor genomic, transcriptomic, and immune features, using MSK-IMPACT assay, gene arrays, Nanostring technology, and TIL assessment on H&E.

    Cell Polarity and Cell Adhesion Associated Gene Expression Differences between Invasive Micropapillary and No Special Type Breast Carcinomas and Their Prognostic Significance

    Researchers analyzed mRNA expression profiles and the prognostic value of 43 genes involved in cell polarity, cell-adhesion and epithelial–mesenchymal transition in invasive micropapillary carcinoma of the breast tumors and compared them to invasive breast carcinomas of no special type.

    Evidence for Accelerated Aging in Mammary Epithelia of Women Carrying Germline BRCA1 or BRCA2 Mutations

    The authors showed that histologically normal breast tissue from younger women who were susceptible to breast cancer, as a result of harboring a germline mutation in BRCA1, BRCA2or PALB2 genes, exhibited hallmarks of accelerated aging.

    tRNA-Derived Small RNAs: Novel Regulators of Cancer Hallmarks and Targets of Clinical Application

    Scientists focus on the basic characteristics of tRNA-derived small RNAs (tsRNAs), and their biological functions known thus far, and explored the regulatory roles of tsRNAs in cancer hallmarks including proliferation, apoptosis, metastasis, tumor microenvironment, drug resistance, cancer stem cell phenotype, and cancer cell metabolism.
