Developing an effective RNA interference strategy against a plus-strand RNA virus: silencing of coxsackievirus B3 and its cognate coxsackievirus-adenovirus receptor.

abstract：:This review addresses many of the chemical aspects of nitrosative stress mediated by N2O3. From a cellular perspective, N2O3 and the resulting reactive nitrogen oxide species target specific motifs such as thiols, lysine active sites, and zinc fingers and is dependant upon both the rates of production as well as consu...
