siRNA is a class of small (20-30 nucleotides), double-stranded, non-coding RNA molecules. siRNA regulates eukaryotic gene expression at the most important levels of genome function, including chromosome segregation, chromatin structure, RNA processing, RNA stability, transcription, and translation. However, naked siRNA will degrade rapidly as there are a large number of RNases in the blood, which will affect the drug efficacy of RNAi. Therefore, it’s very important to improve the stability of naked siRNA. Nowadays, the drug delivery system is becoming an important tool for delivering candidate siRNA drugs to target cells.
We believe that our advanced technology in drug delivery will open the door for the research of more and more siRNA drug delivery systems, and be enabling for targeted therapeutics.
