Introduction: Previous studies and our works have indicated several cation channels in the rat brain mitochondrial inner membrane. In this work, we report the single-channel characterization of a cation channel from the rat brain mitochondrial inner membrane incorporated into a planar lipid bilayer. Methods: After removing and homogenizing the adult rat brain, its supernatant was centrifuged...

An AIPE-active iridium(III) complex was found to possess high specificity for mitochondria, superior photostability, low cytotoxicity, and high resistance to the loss of mitochondrial membrane potential. Thus, this complex can be used for mitochondrial imaging and tracking in living cells.

Modest depolarization of the mitochondrial inner membrane potential is known to attenuate mitochondrial reactive oxygen species generation. Transient pharmacologic uncoupling of mitochondrial oxidative phosphorylation results in modest depolarization of the mitochondrial membrane potential and confers protection against subsequent cardiac ischemia-reperfusion injury. Whether cardiac mitochondri...

Mitochondrial membrane potential varies, depending on energy demand, subcellular location, and morphology and is commonly used as an indicator of mitochondrial functional status. Electrophoretic mobility is a heterogeneous surface property reflective of mitochondrial surface composition and morphology, which could be used as a basis for separation of mitochondrial subpopulations. Since these pr...

B-acute lymphoblastic leukemia (B-ALL) is the frequent pediatric malignity. Chemotherapy is the most practical approaches to deal with such malignancies. Microtubule-targeted agents are one of the most strategic drugs which formerly use in chemotherapy.Although,colchicine-binding anti-tubulin agents exhibited promising effects in clinical trials, their exact mechanism of action is not fully und...

econazole nitrate (en), a synthetic compound, is now in use as a routine antifungal drug. en was shown to have antitumor effect, the tumor cell killing mechanisms, however, remain unclear. in this research, the apoptosis-inducing effect of en on mcf-7 cells was investigated. the results showed that en inhibited the proliferation of mcf-7 cells in a time- and dose-dependent manner by mtt method ...

Schizophrenia is a chronic and often debilitating illness which affects about 1% of the world population. Some reagents have been used to simulate schizophrenic disorders in laboratory animals, such as amphetamine and ketamine. Previous studies have suggested that reactive oxygen species (ROS) production, reduced levels of ATP, mitochondrial dysfunction and apoptosis are involved in the pathoph...
