CDC42 Polarity Controls Intestinal Stem Cell Fate
2026-08-28
Zhang and colleagues show that CDC42-dependent apical-basal polarity regulates the intestinal stem cell-to-transit-amplifying cell transition through a YAP/TAZ–Ereg–EGFR–mTOR cascade that operates independently of canonical Wnt signaling. The study combines inducible mouse genetics with pathway-specific rescue experiments, providing a mechanistic framework for understanding how epithelial organization controls crypt proliferation.

Measuring Cancer Drug Responses Beyond Viability
2026-08-25
Hannah R. Schwartz’s 2022 dissertation shows why relative viability and fractional viability should not be treated as interchangeable measures of anticancer drug response. Its central contribution is a time-aware framework that separates proliferative arrest from cell killing, improving interpretation of in vitro drug-response experiments and their translation to cancer models.

CircCHSY1–HO1 Signaling in Cardiac I/R Injury
2026-08-25
Tan and colleagues show that circCHSY1 is induced after myocardial ischaemia/reperfusion and protects cardiomyocytes through a circCHSY1–miR-24-3p–HO1 regulatory axis. By combining mouse, primary cardiomyocyte, and human embryonic stem cell-derived cardiomyocyte models with gain-of-function, binding, and rescue experiments, the study links circular RNA regulation to mitochondrial preservation during acute cardiac injury.

Cross-Talk in Teicoplanin and A40926 Biosynthesis
2026-08-24
The 2023 reference study shows that pathway-specific regulators in teicoplanin and A40926 biosynthesis are not uniformly interchangeable, despite some shared evolutionary relationships. Its cross-complementation experiments distinguish regulator classes that preserve function across hosts from those whose activity depends strongly on pathway and cellular context, informing glycopeptide-antibiotic strain engineering.

Cy5 amine (non-sulfonated): Labeling Workflow
2026-08-22
Cy5 amine (non-sulfonated) provides a primary amine for covalent attachment to activated biomolecules, polymers, and other compatible substrates in red/far-red fluorescence workflows. Because it is insoluble in water, it should be prepared in an organic co-solvent before transfer into an aqueous labeling reaction; it is intended for research use and not for diagnostic or medical applications.
