The paper investigates metal homeostasis changes in quiescent cells induced by different triggers and finds trigger-specific remodeling of metal pools and associated gene expression.

The paper develops a peptide-based sensor to measure PI(4,5)P2 densities in membranes, showing mutation-specific changes in surface levels in cells with Ras mutations.

This paper develops a fluorescent probe to track PI(4,5)P2 dynamics in neurons, revealing that hallucinogenic ligands at the 5-HT2A receptor cause slower initial PI(4,5)P2 depletion compared to non-hallucinogenic ligands.

The paper introduces a novel ratiometric fluorescent sensor, TRapH, for tracking intracellular pH in living cells and demonstrates its use in monitoring pH dynamics induced by a synthetic H+-transporter.
