CCR7–Notch1 Crosstalk Drives Mammary Cancer Stemness
2026-09-17
Boyle et al. show that CCR7 and Notch1 form a functional signaling circuit that sustains stem-like behavior in MMTV-PyMT mammary cancer cells. The study supports dual pathway investigation while also clarifying that biochemical purification tools can complement, but not replace, cell-based cancer stemness assays.

Berberine, RXRα/PPARγ, and SASP in Atherosclerosis
2026-09-14
A 2025 study identifies an RXRα/PPARγ/NEDD4 signaling axis through which berberine suppresses senescence-associated secretory phenotype inflammation in macrophage-derived foam cells and atherosclerotic plaques. Its combination of ApoE−/− mouse experiments, foam-cell models, Smart-seq profiling, and macrophage-specific RXRα knockdown provides a mechanistic framework for linking nuclear-receptor activity to ubiquitin-dependent regulation of the GATA4/p62 complex.

Methyl-β-cyclodextrin: Membrane Workflow Guide
2026-09-11
Methyl-β-cyclodextrin (MβCD) supports controlled membrane cholesterol extraction and related studies of lipid organization, membrane fluidity modulation, and cholesterol-dependent signaling. It is intended for controlled scientific research workflows only, not diagnostic, clinical, or therapeutic use, and working conditions should be optimized with appropriate cell and vehicle controls.

HMGB1 Exosomes in Lupus Nephritis Endothelial Injury
2026-09-10
The reference study identifies podocyte-derived exosomal HMGB1 as a mediator of glomerular endothelial cell injury in lupus nephritis, acting partly through TRIM27 upregulation. Its combination of patient material, lupus-like mice, donor–recipient cell assays, vesicle perturbation, and genetic manipulation provides a useful framework for testing exosome-dependent kidney injury mechanisms.
