RNA interference and ischemic injury

In the early period of 21st century, RNA interference (RNAi) had emerged as one of the most important discoveries. This highly conserved endogenous gene silencing mechanism has been largely exploited as a powerful tool to determine biological functions of each gene. Both direct introduction of chemically synthesized small interference RNA (siRNA) and a plasmid or viral vectors encoding for siRNA can allow especially stable RNA knockdown. Recently, it has been widely used in the production of therapeutic drugs against hepatitis or immuno-deficiency viruses in human beings. Here, we provide a brief overview of the RNAi mechanism and the technology of RNAi on ischemic injury.
