Webb12 apr. 2024 · The structure of RNA was previously shown to be critical for its functional interactions with other RNAs and protein targets within the cell, including functional folding of catalytic RNAs (e.g., ribozymes; Gabryelska et al., 2013), interactions of viral RNAs with host cellular components (Ziv et al., 2024) and the ability of microRNAs to bind the 3′ … Ribozymes have been proposed and developed for the treatment of disease through gene therapy. One major challenge of using RNA-based enzymes as a therapeutic is the short half-life of the catalytic RNA molecules in the body. To combat this, the 2’ position on the ribose is modified to improve RNA stability. One area of ribozyme gene therapy has been the inhibition of RNA-based viruses.
