Filipin III: Membrane Cholesterol Detection
2026-09-12
Filipin III is a polyene macrolide antibiotic used for cholesterol detection in membranes, membrane cholesterol visualization, and membrane-domain studies. Its cholesterol-associated fluorescence quenching and selective vesicle-lysis profile make it useful for localization, but not as a standalone quantitative cholesterol assay.

Nanoparticle mRNA Delivery Reverses Trastuzumab Resistance
2026-09-11
Dong and colleagues developed a tumor-microenvironment-responsive nanoparticle system for systemic delivery of PTEN mRNA in trastuzumab-resistant HER2-positive breast cancer models. The approach restored PTEN expression, inhibited persistently active PI3K/Akt signaling, and improved the antitumor effect of trastuzumab, while also illustrating the delivery barriers that must be addressed in therapeutic mRNA research.
