Graphical Abstract
  • messenger (mRNA) to stop the synthesis of proteins using short strands of DNA, now known as antisense oligonucleotides, was first coined about 40 years ago [1]. Almost 20 years later, another endogenous mechanism, known as RNA interference (RNAi) was discovered when it was shown that short stretches of

Another noteworthy advancement is the ease and scale with which oligonucleotides are being produced today. Without access to larger

  • control [7]. So far several strategies have been reported to control the WSSV, including activation of the immune system, DNA vaccines, herbal extracts, and RNA interference (RNAi) [8][9]. Among them, the RNAi technology has shown great potential to protect shrimp against the WSSV in some lab-scale
  • experiments [10][11]. The RNAi mechanism comprises a set of cellular processes of posttranscriptional gene silencing that begins with administering the double-stranded RNA (dsRNA). It concludes with a specific gene silencing based on sequence homology between the digested fragments of the dsRNA and the gene

  • , more potent than AONs or ribozymes for gene knockdown, is centered on the RNA interference (RNAi) mechanism, which uses two natural pathways for gene silencing. One is guided by double-stranded siRNAs of 19–23 nucleotides in length that are fully complementary to the mRNA targets, and the other is
