Universal RNA editing in a human liver at the fetal stage

It is known that RNA editing occurs in human cells, which can change the information transmission from DNA to RNA and proteins. Most previous studies have focused on editing of the mRNAs. Here we reported that several kinds of RNAs, including miRNA, rRNA, mRNA, miscRNA and unknown RNA, exhibited base editing in a human fetal liver. Several editing types are displayed. Our data reveals that RNA editing may occur in different species of RNAs.This study was supported by the Huazhong University of Science and Technology (2010MS034).Peer Reviewe
