The estrogen receptor (ER)-negative breast cancer subtype is aggressive with few treatment options available. To identify specific prognostic factors for ER-negative breast cancer, this study included 705,729 and 1034 breast invasive cancer patients from the Surveillance, Epidemiology, and End Results (SEER) and The Cancer Genome Atlas (TCGA) databases, respectively. To identify key differential kinase-substrate node and edge biomarkers between ER-negative and ER-positive breast cancer patients, we adopted a network-based method using correlation coefficients between molecular pairs in the kinase regulatory network. Integrated analysis of the clinical and molecular data revealed the significant prognostic power of kinase-substrate node and edge features for both subtypes of breast cancer. Two promising kinase-substrate edge features, CSNK1A1-NFATC3 and SRC-OCLN, were identified for more accurate prognostic prediction in ER-negative breast cancer patients.

The estrogen receptor (ER or ERα) remains the primary therapeutic target for luminal breast cancer, with current treatments centered on competitive antagonists, receptor down-regulators, and aromatase inhibitors. Despite these options, resistance frequently emerges, highlighting the need for alternative targeting strategies. We discovered a novel mechanism of ER inhibition that targets the previously unexplored interface between the DNA-binding domain (DBD) and ligand-binding domain (LBD) of the receptor.

Nitric oxide (NO) is a multifunctional signaling molecule in oncology, influencing tumor progression, apoptosis, and immune responses. In contrast, chlorambucil (Cbl), a DNA-alkylating chemotherapeutic, induces cytotoxicity through DNA damage. Here, we report a photoresponsive nanoparticle platform for sequential codelivery of NO and Cbl, where NO is released within 10 min of irradiation, followed by Cbl release within 30 min.

Paraneoplastic cerebellar degeneration (PCD) is a rare neurological disorder caused by tumor-mediated antibodies targeting the cerebellum, often leading to irreversible cerebellar damage. The most common antibody implicated in PCD is anti-Purkinje cell cytoplasmic antibody type-1, associated with malignancies such as breast, gynecological, and lung cancers. Symptoms often include dizziness, imbalance, progressive ataxia, and other cerebellar signs/symptoms, but early presentations may mimic acute vestibular syndrome, thus complicating diagnosis.

Endothelial Colony-Forming Cells (ECFCs) are recognized as key vasculogenic progenitors in humans and serve as valuable liquid biopsies for diagnosing and studying vascular disorders. In a groundbreaking study, Anceschi et al. present a novel, integrative strategy that combines ECFCs loaded with gold nanorods (AuNRs) to enhance tumor radiosensitization through localized hyperthermia.
