How are RNAi made?

RNAi is a natural process that works like a “dimmer switch” to dial down the level of a protein. It likely evolved to protect cells from viruses. It begins when a form of RNA made of two strands (double-stranded RNA, or dsRNA) is introduced into the cell, for example by a virus, or produced in the cell.

Is shRNA reversible?

(vii) Gene silencing is reversible. Soon after discontinuation of the treatment, shRNA expression ceases, the level of the target protein widely reverts to pretreatment levels, and the metabolic phenotype returns to normal within 3 weeks.

How is siRNA manufactured?

These siRNA duplexes are produced naturally when an enzyme, Dicer, cleaves long dsRNA (double-stranded RNA) into smaller fragments. The resulting 21-23 nucleotide dsRNA fragments, i.e. siRNA, then associate with an RNase-containing complex to form the RISC (RNA-induced silencing complex).
