Abstract:
Antisense oligonucleotides have the potential to make revolutionary contributions to basic science and medicine. Oligonucleotides can bind mRNA and inhibit translation. Because they can be rapidly synthesized to be complementary to any sequence, they offer ideal tools for exploiting the massive amount of genome information now available. However, until recently, this potential was largely theoretical, and antisense experiments often produced inconclusive or misleading outcomes. This review will discuss the chemical and biological properties of some of the different types of oligomers now available and describe the challenges confronting in vitro and in vivo use of oligonucleotides. Oligomers with improved chemical properties, combined with advances in cell biology and success in clinical trials, are affording powerful new options for basic research, biotechnology, and medicine.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

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...
