RNA editing using the flap endonuclease 1 guided by hairpin DNA probes


ABSTRACT: Here we characterized a flap endonuclease 1 (FEN1) plus hairpin DNA probe (hpDNA) system, called the HpSGN system, for both DNA and RNA editing without sequence limitation.To investigate the mRNA on/off target cleavage effective of the HpSGN system,we co-transformed HepG2 (liver hepatocellular cells) with plasmids encoding FEN1 with NES and two groups of hpDNAs targeting the mRNA of AFP (Alpha Fetoprotein) gene and CDK9 (Cyclin-dependent kinase 9) gene, respectively. RNA-seq was used to examine the on/off taget cleavage effective.We proved the HpSGN system can knock down specific mRNAs in human cells at a level of ~25%.At the same time,it indicated that a degree of off-targets occur in HpSGN-treated cells.
