Abstract:
The manifestation of RNA interference (RNAi)-based therapeutics lies in safe and successful delivery of small interfering RNAs (siRNAs), the molecular entity that triggers and guides sequence-specific degradation of target mRNAs. Optimizing the chemistry and structure of siRNAs to achieve maximum efficacy is an important parameter in the development of siRNA therapeutics. The RNAi protein machinery can tolerate a variety of non-canonical modifications made to siRNAs, each of which imparts advantageous properties. Here, we review these modifications to siRNAs in pre-clinical and clinical studies.

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...
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.
