Reductive stress imaging in the endoplasmic reticulum by using living cells and zebrafish

Chem Commun (Camb). 2019 Aug 21;55(65):9629-9632. doi: 10.1039/c9cc04711e. Epub 2019 Jul 29.

Abstract

Excessive accumulation of reducing agents in the ER leads to a constitutively high UPR. And the co-function of GSH, Cys and HOCl in biological processes is not well understood. To address this, a TP probe, NPCC, was developed for monitoring reductive stress in the ER. It can also distinguish cancer cells from normal cells.
