To identify the mechanisms by which oxidative stress with oxidizing agents alters the activity of ion channels in human retinal pigment epithelial (RPE) cells. The effects of oxidizing agents on ion currents were investigated in human RPE R-50 cells with

The spectroelectrochemistry of camphor-bound cytochrome P450cam (P450cam) using gold electrodes is described. The electrodes were modified with either 4,4(')-dithiodipyridin or sodium dithionite. Electrolysis of P450cam was carried out when the enzyme was in solution, while at the same time UV-visible

Experimental determination of the number of thiols in a protein requires methodology that combines high sensitivity and reproducibility with low intrinsic thiol oxidation disposition. In detection of disulfide bonds, it is also necessary to efficiently reduce disulfides and to quantify

To understand better the modulation of ryanodine receptors (RyRs) during oxidative stress, the effect of 4,4'-dithiodipyridine (DTDP), a cell-permeant and thiol-reactive oxidant, on global Ca(2+) signal and spontaneous Ca(2+) sparks of rat ventricular myocytes was investigated. It was shown that

The effect of oxidants on Ca(2+) movement in osteoblasts is unclear. In this study, we show that 4,4'-dithiodipyridine (4,4'-DTDP), a reactive disulphide that mobilizes Ca(2+) in muscle, induces an increase in cytoplasmic free-Ca(2+) concentrations ([Ca(2+)](i)) in MG63 human osteosarcoma cells
