J Biol Chem. 2005 May 20;280(20):19911-24. Epub 2005 Mar 11.

In addition, SFN treatment resulted in an increase in the level of Fas, activation of caspase-8, and cleavage of Bid.
The SFN-induced ROS generation was significantly attenuated on pretreatment with mitochondrial respiratory chain complex I inhibitors, including diphenyleneiodonium chloride and rotenone.

This feature was preceded by an enhancement in the caspase-9 activity (2h), whereas caspase-8 activity remained unchanged.

Siglec-8 crosslinking induced rapid cleavage of caspase-3, caspase-8, and caspase-9 in eosinophils.
Rotenone and antimycin, inhibitors of mitochondrial respiratory chain components, completely inhibited apoptosis.

J Cardiovasc Pharmacol. 2000 Nov;36(5 Suppl 1):S201-4.


In this study, we applied mitochondrial inhibitors, such as rotenone, cobalt chloride and antimycin A, which inhibit mitochondrial function at different sites of the mitochondrial respiratory chain, to cardiomyocytes.
