Small Interfering RNA (siRNA)

Small Interfering RNA (siRNA) is a small exogenous double-stranded RNA (dsRNA) (20-25 nucleotides), which triggers the RNA interference (RNAi) pathway. The short dsRNA unwinds and the sense strand is degraded. Antisense strand forms RNA induced silencing complex (RISC) with various protein components. The antisense strand retained in RISC is specifically complementary to the target gene mRNA. Meanwhile, RISC has nuclease activity, which can cut and degrade the target gene mRNA, and inhibit the expression of target gene. Incomplete complementarity results in mRNA translation inhibition.

  • HY-132591
    Inclisiran (ALN-PCSsc) is a double-stranded small interfering RNA (siRNA) molecule that inhibits the transcription of PCSK-9. Inclisiran can be used for hyperlipidemia and cardiovascular disease (CVD) research.
  • HY-132588
    Lumasiran (ALN-G01), a siRNA product, reduces hepatic oxalate production by targeting glycolate oxidase. By silencing the gene encoding glycolate oxidase, Lumasiran depletes glycolate oxidase and thereby inhibits the synthesis of oxalate, which is the toxic metabolite that is directly associated with the clinical manifestations of Primary hyperoxaluria type 1 (PH1).
  • HY-132609
    Patisiran sodium
    Patisiran sodium is a double-stranded small interfering RNA that targets a sequence within the transthyretin (TTR) messenger RNA. Patisiran sodium specifically inhibits hepatic synthesis of mutant and wild-type TTR. Patisiran sodium can be used for the research of hereditary TTR amyloidosis.
