Mechanism of sirna interference
WebRNA interference (RNAi) is one of the pathways, collectively named RNA silencing pathways, that employ small RNAs as guides for sequence-specific silencing [reviewed in ( Ketting, 2011 )]. RNAi was discovered in C. elegans and defined as sequence-specific mRNA degradation induced by long double-stranded RNA (dsRNA) ( Fire et al., 1998 ). WebJan 17, 2024 · It is also known as RNA interference (RNAi). [1] [2] The siRNA agents initiate their RNAi action in the cytoplasm with the help of an enzyme, endoribonuclease dicer, …

This is … WebMay 1, 2024 · The mechanism of action of small interfering RNA (siRNA) is based on post-transcriptional gene silencing. siRNA molecules are usually specific and efficient in the knockdown of disease-related genes.
A decade after the discovery of RNAi mechanism in 1993, the pharmaceutical sector heavily invested in the research and development of siRNA therapy. There are several advantages that this therapy has over small molecules and antibodies. It can be administered quarterly or every six months. Another advantage is that, unlike small molecule and monoclonal antibodies that need to recognize specific conformation of a protein, siRNA functions by Watson-Crick basepairing with …
