NDV-D90 Inhibits 17β-Estradiol-Mediated Resistance to Apoptosis by Differentially Modulating Classic and Nonclassic Estrogen Receptors in Breast Cancer Cells

Scientists investigated whether Newcastle disease virus (NDV)‐D90, a novel strain isolated from natural sources in China, promoted apoptosis by modulating the expression of ERα or the GPER in breast cancer cells exposed to 17β‐estradiol.

Upregulation of S100A10 in Metastasized Breast Cancer Stem Cells

Knockdown of S100A10 in breast cancer cells suppressed and overexpression of S100A10 in breast cancer patient‐derived tumor xenograft cells enhanced their invasion abilities and 3D organoid formation capacities in vitro.

Introduction of hsa-MiR-512-3p as a New Regulator of HER2 Signaling Pathway in Breast Cancer

Researchers found that miR-512-3p acted as a cell-type-specific tumor suppressor, through targeting HER2, HER3, PIK3R2, and AKT1 transcripts.

Annurca Apple Polyphenol Extract Promotes Mesenchymal-to-Epithelial Transition and Inhibits Migration in Triple-Negative Breast Cancer Cells through ROS/JNK Signaling

By qualitatively and quantitatively monitoring the real-time movements of live cells researchers provided the first evidence that pple polyphenol extract inhibited the migration of MDA-MB-231 and MDA-MB-468 TNBC cells and downregulated metalloproteinase-2 and metalloproteinase-9.

Ambrisentan, an Endothelin Receptor Type A-Selective Antagonist, Inhibits Cancer Cell Migration, Invasion, and Metastasis

In vitro, Ambrisentan inhibited both spontaneous and induced migration/invasion capacity of different tumor cells. Whole transcriptome analysis using RNAseq indicated Ambrisentan’s inhibitory effects on the whole transcriptome of resting and PAR2-activated COLO-357 cells, which tended to normalize to an unstimulated profile.

ARe We There Yet? Understanding Androgen Receptor Signaling in Breast Cancer

As both prostate and breast cancers often share a reliance on nuclear hormone signaling, there is increasing appreciation of the overlap between activated cellular pathways in these cancers in response to androgen signaling.

Loss of Proprotein Convertase Furin in Mammary Gland Impairs proIGF1R and proIR Processing and Suppresses Tumorigenesis in Triple Negative Breast Cancer

Investigators report that Furin was frequently overexpressed in TNBC tumors and this correlated with poor prognosis in patients with TNBC tumors.
