    摘要: Methods for affecting mRNA expression or translation through the modification of pre-mRNA or mRNA transcripts are described. In one embodiment of the methods of the present invention, the branch point adenosine of a pre-mRNA transcript is 2′-O-methylated to block splicing and subsequent expression of the protein encoded by the transcript. In another embodiment, a uridine residue in a nonsense stop codon may be modified to pseudouridine, causing the translation machinery to read through the nonsense stop codon and translate a full length protein.

    摘要: Processes and C/D box small nucleolar RNAs (snoRNAs) for altering telomerase activity and altering telomerase length are described. The processes of the invention involve the use of C/D box snoRNAs for targeted 2′-O-methylation modification of nucleotides in a pseudoknot region of the telomerase RNA. Depending on their position, the 2′-O-methylation modifications can cause an increase in telomerase activity and subsequent telomere lengthening or a decrease in telomerase activity and subsequent telomere shortening.
