RNA editing is a gene editing technology that has emerged in recent years
On February 10, 2022, Peking University Wei Wensheng's group published a long research paper on Engineered circular ADAR-recruiting RNAs increase the efficiency and fidelity of RNA editing in vitro and in vivo in the journal Nature Biotechnology .
Circular RNA has no 5' or 3' end, can avoid exonuclease cleavage, and has better stability and longer half-life in cells than linear RNA
Figure 1: Circ-arRNA enables efficient and precise editing of endogenous transcripts
Since the substrate of ADAR protein is double-stranded RNA, the adenylate in the double-stranded region formed by targeting RNA and circ-arRNA will have different probability of deamination risk
Figure 2: LEAPER 2.
The next evaluation of the application potential of LEAPER 2.
Doctoral student Yi Zongyi (CLS), postdoctoral fellow Quan Liang and doctoral student Tang Huixian (BIOPIC) from Peking University Wei Wensheng's research group are the co-first authors of the paper
