Abstract:
Double stranded short interfering RNAs (siRNAs) mediate gene silencing in a sequence specific manner. By virtue of their specific gene silencing activity and owing to the recent discoveries on their plasmid and virus driven expression, siRNAs are being widely adopted in research and therapeutics. Efforts were made to optimize the siRNA expression system for the application in therapy. One major obstacle in developing RNA interference (RNAi) therapy is the delivery of siRNAs to the target cells. Combination of novel molecular targeting technologies, such as recombinant protein technology and ribosome display technology, will enable to deliver gene silencing agents to target cells specifically and efficiently.

siRNA - Small Interfering RNAs
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the ATP-dependent...
RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
