The mitochondrial respiratory chain is a modulator of apoptosis
Mitochondrial dysfunction and dysregulation of apoptosis are implicated in many diseases such as cancer and neurodegeneration. We investigate here the role of respiratory chain (RC) dysfunction in apoptosis, using mitochondrial DNA mutations as genetic models. Although some mutations eliminate the entire RC, others target specific complexes, resulting in either decreased or complete loss of ele...

متن کاملThe mitochondrial respiratory chain.
In the present chapter, the structures and mechanisms of the major components of mammalian mitochondrial respiratory chains are reviewed. Particular emphasis is placed on the four protein complexes and their cofactors that catalyse the electron transfer pathway between oxidation of NADH and succinate and the reduction of oxygen to water. Current ideas are reviewed of how these electron transfer...
متن کاملThe Aerobic Mitochondrial Respiratory Chain
INTRODUCTION Fumarate reductase (FRD) catalyses the reduction of fumarate to succinate and is a key enzyme for the anaerobic functioning of many organisms respiring with fumarate as terminal electron acceptor. The ability to reduce fumarate is a common property among Gram-negative bacteria and some facultative anaerobic Gram-positive bacteria. The reduction of fumarate is also important in the ...
متن کاملProtein Kinase A/CREB Signaling Prevents Adriamycin-Induced Podocyte Apoptosis via Upregulation of Mitochondrial Respiratory Chain Complexes.
Previous work showed that the activation of protein kinase A (PKA) signaling promoted mitochondrial fusion and prevented podocyte apoptosis. The cAMP response element binding protein (CREB) is the main downstream transcription factor of PKA signaling. Here we show that the PKA agonist 8-(4-chlorophenylthio)adenosine 3',5'-cyclic monophosphate-cyclic AMP (pCPT-cAMP) prevented the production of a...
