Copper plays a key role in the modulation of cellular function, defence, and growth. Here we present InCCu1, a ratiometric fluorescent sensor for mitochondrial copper, which changes from red to blue emission in the presence of Cu(i). Employing this probe in microscopy and flow cytometry, we show that cisplatin-treated cells have an impaired ability to accumulate copper in the mitochondria.
Induction of apoptosis of virus-infected cells is an important host cell defence mechanism. However, some viruses have incorporated genes that encode anti-apoptotic proteins or modulate the expression of cellular regulators of apoptosis. Here, Edgar Meinl and colleagues discuss recent evidence that viral interference with host cell apoptosis leads to enhanced viral replication, and to evasion o...
Despite the importance of NHX1 (Na(+)/H(+) exchanger 1) in plant salt tolerance, little is known about its other functions. In this study, intriguingly, it was found that NHX1 participated in plant disease defence against Phytophthora parasitica var. nicotianae (Ppn) in Nicotiana benthamiana. NbNHX1 was originally isolated from N. benthamiana, and characterized. The subcellular localization of ...
A novel cellular response to oxidative stress has been discovered, in which the activity of a molecular chaperone, Hsp33, is modulated by the environmental redox potential. This provides a rapid first defence mechanism against the potentially very harmful toxic effects of oxidative stress.
