 siRNAs loaded on AGO can also function similarly to miRNAs, suppressing hundreds of offtarget transcripts wherever the seed region can make a match 18However, accumulated evidences revealed that siRNA could downregulate unintended genes with partial complementarities mainly to the 7nucleotide seed region of siRNA This phenomenon is referred to as offtarget effectOur siRNA design algorithms incorporate strategies described by our product scientists in peerreviewed publications1, 2 These groundbreaking methods enhance specificity of silencing by reducing offtarget effects caused by the siRNA seed region Pooling of siRNAs better mimics the natural RNAi pathway and when combined with Thermo Scientific

Large‐scale studies based on knockdown experiments have made it evident that off‐target effect arises due to base pairing of the 2‐8 nucleotides at 5′ end or seed region of siRNA guide strand, with a nearly complementary sequence in the untranslated region of a non‐targeted mRNA 15 Keeping the benchmark of 215°C for the seed duplex stability or T m value of the binding ofThe seed region of siRNA guide strand and target mRNA (seedtarget duplex) (Figure 1a) 12 Furthermore, we have developed a DNARNA chimeric siRNA (chiRNA) with deoxyribonucleotides in the 5' proximal eight nucleotides of the guide strand and the complementary nucleotides The chiRNA showed virtually no offtarget effects,To utilise this, we further screened 13 potential siRNAs whose seed sequences were matched to known antifibrotic miRNAs and confirmed their miRNAlike activity A miR27mimicking siRNA designed to target the nsp12 region (27/RdRP) was validated to silence a synthesised nsp12 RNA mimic in lung cell lines and function as an antifibrotic miR27

That seeddependent offtarget effect of siRNA could activate Ecadherin transcription via suppression of its negative transcription factor(s) The seeddependent offtarget effect is shown to be induced by complementarity in the 7nt seed region mainly positioned 2–8 from the 59 end of the siRNA guide strand 14, 37, 38Seed region The chemical modifications of deoxyribonucleic acid (DNA), PS, and DNA−PS were introduced into all of the seven nucleotides of the seed region of the siRNA guide strand (Figure 2b) In addition, 3 (positions 4−6), 5 (positions 3−7),Our results confirm previous reports that strength of basepairing in the siRNA seed region is the primary factor determining the efficiency of offtarget silencing However, the degree of downregulation of offtarget transcripts with shared seed sequence is not necessarily similar, suggesting that there are additional auxiliary factors that influence the silencing potential
