Abstract[English]
The present invention relates to circular RNA molecules, methods of producing circular RNA molecules, circular and non-circular intermediates thereof, and methods of treating or preventing a disease. In particular, the present invention provides circRNAs that can be prepared via chemical circularization of RNA, regardless of the circRNA sequence, length or size. Due to chemical nature of the circularization process, it allows the attachment of tags, markers, etc. after the circularization at a position in close proximity to the position where the circRNA was circularized.[French]
La présente invention concerne des molécules d'ARN circulaire, des procédés de production de molécules d'ARN circulaire, leurs intermédiaires circulaires et non circulaires, et des méthodes de traitement ou de prévention d'une maladie. En particulier, la présente invention concerne des ARNc qui peuvent être préparés par circularisation chimique de l'ARN, indépendamment de la séquence, de la longueur ou de la taille de l'ARNc. En raison de la nature chimique du processus de circularisation, celui-ci permet la fixation d'étiquettes, de marqueurs, etc. après la circularisation, en une position à proximité immédiate de la position où l'ARNc a été circularisé.
