Abstract:
Among the technologies available for gene knockdown RNase H-dependent antisense oligonucleotides and RNAi are very popular. Both offer specificity and efficient knockdown of the genes; both are useful tools to study gene functions. Antisense and RNAi methods share many practical problems such as site selection, toxicity at high concentration, and the difficulty of transfection in certain cell types. We will focus in this review on the most important issues in the development of both methods and their possible use in gene-silencing therapy.

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...

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...
