Antagonists of the Serotonin Receptor 5A Target Human Breast Tumor Initiating Cells

Researchers found that selective antagonists of 5-HT5A reduced the frequency of tumorsphere initiating cells residing in breast tumor cell lines and those of patient-derived xenografts that they established.

Rosmarinic Acid-Induced Apoptosis and Cell Cycle Arrest in Triple-Negative Breast Cancer Cells

Researchers evaluated the effects and mechanisms of rosmarinic acid (RA) in two racially different TNBC cell lines. Results obtained showed that RA significantly caused cytotoxic and antiproliferative effects in both cell lines in a dose- and time-dependent manner. RA induced cell cycle arrest-related apoptosis and altered the expression of many apoptosis-involved genes differently.

Distinct Phenotypes of Cancer Cells on Tissue Matrix Gel

Scientists investigated mammary epithelial cell phenotypes and metabolic profiles on animal breast extracellular matrix-derived tissue matrix gel, Col I, and Matrigel. Atomic force microscopy, fluorescence microscopy, acini formation assay, differentiation experiments, spatial migration/invasion assays, proliferation assay, and nuclear magnetic resonance spectroscopy were used to examine biological phenotypes and metabolic changes.

PRMT1-Dependent Methylation of BRCA1 Contributes to the Epigenetic Defense of Breast Cancer Cells against Ionizing Radiation

Investigators found that by activating PRMT1, irradiation triggered a BRCA1-dependent program that resulted in efficient DNA repair and inhibition of apoptosis. Depletion of PRMT1 in irradiated cells resulted in a switch of BRCA1 functions from repair and survival in the nucleus to activation of cell death signals in the cytoplasm.

Copper (II) Metallodendrimers Combined with Pro-Apoptotic siRNAs as a Promising Strategy Against Breast Cancer Cells

The nanocomplexes formed by metallodendrimers and different siRNA were examined for their zeta potential and size, and by transmission electron microscopy, fluorescence polarisation, circular dichroism, and electrophoresis. The internalisation of dendriplexes was estimated by flow cytometry and confocal microscopy in a human breast cancer cell line, following the ability of these metallodendrimers to deliver the siRNA into the cell. In vitro cell viability experiments have indicated effective interactions between Cu (II) dendrimers and pro-apoptotic siRNAs: Mcl-1 and Bcl-2 in breast cancer cells.

AUF1 Promotes Stemness in Human Mammary Epithelial Cells through Stabilization of the EMT Transcription Factors TWIST1 and SNAIL1

Scientists showed that AU-rich element RNA-binding protein 1 was an important inducer of the epithelial-to-mesenchymal transition process through stabilization of SNAIL1 and TWIST1 and the consequent promotion of breast cancer stem cells.

Discrete Adaptive Responses to MEK Inhibitor in Subpopulations of Triple-Negative Breast Cancer

The authors defined the differential responses to trametinib in subpopulations of a clinically-relevant in vitro model of TNBC, and identified both adaptive and acquired elements that contribute to the emergence of drug resistance mediated by increased expression of CXCR7 and amplification of KRAS.
