Interferons are a family of related and naturally occurring signal proteins grouped in three major species (alpha, beta and gamma) according to their cellular origin and inducing agents and historically described for their antiviral activity. Upon binding to specific receptors they lead to the activation of a signal transduction pathway that activates a(More)
Reactive oxygen species (ROS), including hydrogen peroxide (H2O2), induces injury of endothelium in a variety of pathophysiological conditions, such as inflammation, aging, and cancer. In our study, we characterized the signaling pathway linking oxidative stress induced by sublethal concentrations of H2O2 to p53 in primary human endothelial cells through(More)
This work is the first demonstration that cystamine is actively accumulated in spheroplasts of Saccharomyces cerevisiae. We have identified and quantitatively determined the transported cystamine in extracts of spheroplasts that have been incubated over different time periods and in the presence of different amounts of cystamine. The method used, already(More)
