19277727 Alam Khan MK, Das U, Rahaman MH, Hassan MI, Srinivasan A, Singh TP, Ahmad F: A single mutation induces molten globule formation and a drastic destabilization of wild-type cytochrome c at pH 6.0. J Biol Inorg Chem. 2009 Jun;14(5):751-60. Epub 2009 Mar 10.

Characterization of this mutant by the far-UV, near-UV, and Soret circular dichroism, intrinsic and 1-Anilino-8-naphthalene sulfonate fluorescence, and dynamic light scattering measurements led to the conclusion that the L94G mutant has all the common structural characteristics of a molten globule at pH 6.0 and 25 degrees C.

Addition of 70% (v/v) polyols to TCA (3.3 mM)-induced state of Cyt c resulted in increased 1-anilino-8-naphthalene sulfonate binding and increased mean residue ellipticity at 222 nm, indicating increase in compactness with enhanced exposure of hydrophobic surface area.

The competition between 8-anilino-1-naphthalene sulfonate (ANS) and cyt c for the same binding sites in liposomes that have identical nominal compositions with respect to those of the monolayers was used to obtain binding parameters.

20065042 Zhang Y, Soto J, Park K, Viswanath G, Kuwada S, Abel ED, Wang L: Nuclear receptor SHP, a death receptor that targets mitochondria, induces apoptosis and inhibits tumor growth. Mol Cell Biol. 2010 Mar;30(6):1341-56. Epub 2010 Jan 11.

SHP is a pivotal cell death receptor that targets mitochondria, where it binds with Bcl-2, disrupts Bcl-2/Bid interaction, and induces cytochrome c release.
The apoptosis inducer AHPN {retinoid 6-[3-(1-adamantyl)-4-hydroxyphenyl]-2-naphthalene carboxylic acid} acts by regulating SHP gene expression and promotes the translocation of SHP from the nucleus to the mitochondria.

We observed: (i) that the thickness of the bilayers, calculated from a cross-sectional analysis, decreased as the visualization temperature increased; (ii) the existence of laterally segregated domains that respond to temperature in SPBs of POPE:POPC:CL; (iii) a decrease in height and an increase in roughness (Ra) of SPBs after cytochrome c (cyt c) injection at room temperature.
To obtain further insight into the nature of the interaction between cyt c and the bilayers, the competition between 8-anilino-1-naphthalene sulfonate (ANS) and the protein for the same binding sites in liposomes was monitored by fluorescence.

In contrast, it is a potent killer when migrating to mitochondria, where it binds to Bcl-2 and converts its survival phenotype, triggering cytochrome c release and apoptosis.
Agents, such as 6-[3-(1-adamantyl)-4-hydroxyphenyl]-2-naphthalene carboxylic acid (AHPN/CD437), which induce Nur77 migration from the nucleus to mitochondria, effectively induce apoptosis of cancer cells.

Cancer Res. 2008 Oct 15;68(20):8573-81.

Moreover, caspase-8 and Bid activation, and cytochrome c release, were observed, suggesting the existence of a cross-talk between death receptor and the mitochondrial pathways.

18534571 Mikami M, Goubaeva F, Song JH, Lee HT, Yang J: beta-Adrenoceptor blockers protect against staurosporine-induced apoptosis in SH-SY5Y neuroblastoma cells. Eur J Pharmacol. 2008 Jul 28;589(1-3):14-21. Epub 2008 Apr 25.

We studied the effects of three beta-adrenoceptor blockers propranolol (1-(isoproplyamino)-3-(naphthalene-1-yloxy) propan-2-ol), atenolol (2-[4-[2-hydroxy-3-(1-methylethylamino) propoxyl] phenyl] ehanamide), and ICI 118551 (1-[2,3-(dihydro-7-methyl-1H-iden-4-yl) oxy]-3-[(1-methylethyl) amino]-2-but anol), against staurosporine-induced apoptosis in SH-SY5Y human neuroblastoma cells.
In isolated mitochondria, propranolol and ICI 118551 inhibited staurosporine-induced cytochrome c release while atenolol did not.

GC/MS detection of two carboxylated naphthalene metabolites and transcribed benzylsuccinate synthase, cytochrome c nitrite reductase, and ammonia monooxygenase genes indicated that anaerobic metabolism of aromatic compounds and that both dissimilatory nitrate reduction to ammonia (DNRA) and nitrification were in progress in situ.

The stable folding intermediate state has been characterized by near- and far-UV circular dichroism, tryptophan fluorescence, 8-anilino-1-naphthalene sulfonic acid (ANS) binding, and intrinsic viscosity measurements.
