Currently, the CRISPR-Cas9 system serves as a prevalent tool for genome editing and gene expression regulation. Its therapeutic application is limited by off-target effects that can affect genomic integrity through nonspecific, undesirable changes in the genome. Various strategies have been explored to mitigate the off-target effects.

Small interfering RNA (siRNA) is the most important tool for the manipulation of mRNA expression and needs protection from intracellular nucleases when delivered into the cell. In this work, we examined the effects of siRNA modification with the phosphoryl guanidine (PG) group, which, as shown earlier, makes oligodeoxynucleotides resistant to snake venom phosphodiesterase. We obtained a set of siRNAs containing combined modifications PG/2'-O-methyl (2'-OMe) or PG/2'-fluoro (2'-F); biophysical and biochemical properties were characterized for each duplex.
