PUM3 Is an Essential Suppressor of Replication Stress in Homologous Recombination Deficient Breast Cancer
[Nature Communications] Researchers showed that basal-like breast cancer harbouring the recurrent 9p21.3–9p24 amplicon, and particularly those that are homologous recombination-defective, overexpress Pumilio RNA binding family member 3.
Multiplatform Single-Cell and Spatial Transcriptomics Reveal Sex-Specific Malignant States and Architecture in Male Breast Cancer
[Science Advances] Researchers generated a multiplatform single-cell and spatial transcriptomic atlas, identifying male-specific tumor cells that were enriched in male breast cancer, rare in female breast cancer, and associated with poorer disease-free survival.
Spatial Analysis Dissects the Microenvironmental Architecture of Local Recurrence after Breast-Conserving Surgery
[Cancer Research] Investigators performed single-cell spatial transcriptomics on primary breast cancer and matched ipsilateral breast tumor recurrence (IBTR) specimens from patients to generate a comprehensive atlas of over 600,000 cells, delivering a high-resolution spatial landscape of IBTR.
A USP28-BRD4 Axis Contributes to the Acceleration of Breast Cancer Growth by Hyperglycemia
[Cell Reports] Scientists reported that hyperglycemia stabilizes BRD4 protein, a bromodomain transcriptional coactivator recognizing histone lysine acetylation, to accelerate breast cancer growth.
PRMT1 and YBX1 Cooperatively Transcriptionally Activate GPX4 to Inhibit Ferroptosis and Promote Breast Cancer Progression
[Cancer Letters] Investigators showed that Protein Arginine Methyltransferase 1 is highly expressed in breast cancer and forms a transcriptional activation complex with Y-box binding protein 1.
Anti-Notch Plus Endocrine Therapy in ER+ Breast Cancer Inhibits Cancer Stem Cells by Increasing DAXX
[JCI Insight] Researchers identified Notch-regulated biomarkers by conducting a pre-surgical window study evaluating endocrine therapy combined with the γ-secretase inhibitor (GSI) MK-0752 in estrogen receptor positive breast cancer.
ERa-Induced Ma Reader HNRNPC Maintains DDX6 mRNA Stability to Promote Tumor Progression in ER+BC
[British Journal of Cancer] Researchers unveiled an ERα/heterogeneous nuclear ribonucleoprotein C (HNRNPC)/DDX6 axis in estrogen receptor positive breast cancer.
The Role of Autoproteolysis and Mitoribosomal Proteins in the Regulation of the Mitochondrial LACTB Tumor Suppressor
[EMBO Reports] The authors uncovered a previously undescribed post-translational mechanism by which cancer cells inactivate the potent mitochondrial tumor suppressor LACTB in breast cancers
A Biomarker-Driven Approach to Targeting Polyamine Depletion in Triple Negative Breast Cancer
[Biomarker Research] Scientists demonstrated a biomarker-driven approach to treating TNBC through polyamine depletion using TNBC cell lines, ex vivo tumor slices, and in vivo patient-derived xenograft models with low, moderate and high baseline levels of spermidine/spermine N1-acetlytransferase.
Niclosamide Suppresses Breast Cancer Progression and Enhances Paclitaxel Sensitivity by Targeting the ATP6AP1-YY1-XIAP Axis
[Acta Pharmacologica Sinica] The authors demonstrated that ATPase H+ Transporting Accessory Protein 1 (ATP6AP1) enhances the malignant phenotype of breast cancer cells by upregulating X-linked inhibitor of apoptosis protein (XIAP) expression.
Estrogen-Related Mechanisms Underlying Bisphenol a-Induced Proliferation and Migration in MCF-7 Breast Cancer Cells: An Integrated Network Toxicology, Molecular Docking, and In Vitro Study
[Ecotoxicology and Environmental Safety] Researchers integrated network toxicology, molecular docking, and in vitro validation to systematically evaluate the potential effects of bisphenol A on estrogen-related tumors, including breast, ovarian, and endometrial cancers.
Mammary Gland-Specific Deletion of MTA1 Causes Abrupt Involution through Activation of STAT3 Signaling in Lactating Mice
[Life Sciences] Researchers examined the role of metastasis-associated protein 1 (MTA1) in regulating mammary gland involution using mammary epithelial-specific MTA1 deletion.
