siRNA therapeutics: a clinical reality – Saw PE et. al

they discovered that the silencing effectors in Caenorhabditis elegans (roundworm) were double
stranded RNAs. B
•
This was proved by Single stranded (sense or antisense) RNA or double-stranded RNA encoding for
a muscle protein was injected into C. elegans. Both single-stranded RNA had no effect when
injected separately, but started to twitch when treated with double-stranded RNA, showing similar
phenotypes to C. elegans with defective muscle proteins. This indication denoted that the gene
coding for normal muscle movement had been silenced by the dsRNA.

Why can this be useful in therapeutics?
On August 10, 2018, fda approved treatment of Hereditary Transthyretin Amyloidosis (hATTR). a
rare, progressive, and fatal disease.
Alnylam concluded that Patisiran is capable of significantly improving multiple clinical
manifestations of
hereditary transthyretin amyloidosis (Adams et al., 2018).
