Chemically Modified Antisense Oligonucleotides-Recent Improvements of RNA Binding and Ribonuclease H Recruitment
1Institut für Organische Chemie der Universität, Richard-Willstätter-Allee 2, D-76128 Karlsruhe (Germany).
Abstract:
The incorporation of rationally designed sugar or nucleobase modifications into oligonucleotides gives remarkable improvements of the antisense activity. For example, the cytosine analogue 1 recognizes both the Watson-Crick and the Hoogsteen site of a guanine nucleotide 2, which dramatically enhances the RNA-binding affinity and selectivity.

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...
