Publication number: 20230212574Abstract: A self-circularization RNA construct that can be expressed in a DNA vector and simultaneously circularized through a self-targeting and splicing reaction to form a circRNA is disclosed. The circRNA can consist only of a gene of interest which can be a coding, non-coding, or a combination thereof. The gene of interest has the advantage of being able to rapidly express a peptide or protein. The formed circRNA has a circular structure and has a stable and high half-life because 5? and 3? ends are not exposed. Accordingly, functional RNA such as miRNA, anti-miRNA, siRNA, shRNA, aptamer, functional RNA for gene/RNA editing, ADAR (adenosine deaminase acting on the RNA)-recruiting RNA, mRNA vaccine, mRNA therapeutic agent, vaccine adjuvant, and CAR-T mRNA can be produced as a stable circRNA in cells.Type: ApplicationFiled: October 12, 2022Publication date: July 6, 2023Applicant: Rznomics Inc.Inventors: Seong-Wook LEE, Kyung Hyun LEE, Seung Ryul HAN, Ji Hyun KIM, Seongcheol KIM
