Rotenone, an inhibitor of mitochondrial respiratory chain complex I, is a useful tool to elicit animal model of Parkinson's disease. Rotenone-induced neuronal apoptosis may contribute to the etiology of Parkinson's disease. However, the mechanism of rotenone-induced apoptosis is not fully understood. In the present study, we show that Ca2+ signaling is(More)
The mitochondrial respiratory Complex II or succinate:ubiquinone oxidoreductase (SQR) is an integral membrane protein complex in both the tricarboxylic acid cycle and aerobic respiration. Here we report the first crystal structure of Complex II from porcine heart at 2.4 A resolution and its complex structure with inhibitors 3-nitropropionate and(More)
1-methyl-4-phenylpyridinium ion (MPP(+)), an inhibitor of mitochondrial complex I, has been widely used as a neurotoxin because it elicits a severe Parkinson's disease-like syndrome with elevation of intracellular reactive oxygen species (ROS) level and apoptotic death. Salvianic acid A (SA), isolated from the Chinese herbal medicine Salvia miltiorrhiza, is(More)
Fabrication of advanced artificial nanomaterials is a long-term pursuit to fulfill the promises of nanomaterials and it is of utter importance to manipulate materials at nanoscale to meet urgent demands of nanostructures with designed properties. Herein, we demonstrate the morphological tailoring of self-assembled nanostructures on faceted GaAs nanowires(More)
