Regulation of the permeability transition pore, a voltage-dependent mitochondrial channel inhibited by cyclosporin A.
Petronilli V, Nicolli A, Costantini P, Colonna R, Bernardi P. Petronilli V, et al. Biochim Biophys Acta. 1994 Aug 30;1187(2):255-9. doi: 10.1016/0005-2728(94)90122-8. Biochim Biophys Acta. 1994. PMID: 7521212
Many physiological and pathological effectors, including Ca2+ and ADP, modulate MTP operation directly through changes of the gating potential rather than indirectly through changes of the membrane potential (Petronilli, V., Cola, C., Massari, S., Colonna, R. and Be …

Modulation of the mitochondrial cyclosporin A-sensitive permeability transition pore by matrix pH. Evidence that the pore open-closed probability is regulated by reversible histidine protonation.
Nicolli A, Petronilli V, Bernardi P. Nicolli A, et al. Among authors: petronilli v. Biochemistry. 1993 Apr 27;32(16):4461-5. doi: 10.1021/bi00067a039. Biochemistry. 1993. PMID: 7682848
This is due to locking of the pore in the closed conformation by matrix acidification and fast Ca2+ efflux following membrane depolarization (Petronilli, V., Cola, C., & Bernardi P. (1993) J. Biol. Chem. 268, 1011-1016). Here we show that addition of diethyl pyr …

Interactions of cyclophilin with the mitochondrial inner membrane and regulation of the permeability transition pore, and cyclosporin A-sensitive channel.
Nicolli A, Basso E, Petronilli V, Wenger RM, Bernardi P. Nicolli A, et al. Among authors: petronilli v. J Biol Chem. 1996 Jan 26;271(4):2185-92. doi: 10.1074/jbc.271.4.2185. J Biol Chem. 1996. PMID: 8567677 Free article.
We show that the interactions of this CyP-M pool with submitochondrial particles are disrupted (i) by the addition of CSA, which inhibits the pore, but not of CSH, which does not, and (ii) by acidic pH condition, which also leads to selective inhibition of the MTP; furthermore, w …

Modulation of the mitochondrial permeability transition pore by pyridine nucleotides and dithiol oxidation at two separate sites.
Costantini P, Chernyak BV, Petronilli V, Bernardi P. Costantini P, et al. Among authors: petronilli v. J Biol Chem. 1996 Mar 22;271(12):6746-51. doi: 10.1074/jbc.271.12.6746. J Biol Chem. 1996. PMID: 8636095 Free article.
(ii) A second site coincides with the oxidation-reduction-sensitive dithiol we have recently identified (Petronilli, V., Costantini, P., Scorrano, L., Colonna, R., Passamonti, S., and Bernardi, P. (1994) J. ...
