  • Publication number: 20210355508
    Abstract: Provided is a method for modulating RNA splicing by inducing a base mutation at a splice site or a base substitution in a polypyrimidine region. The method comprises expressing a targeting cytosine deaminase in a cell, to induce AG at a 3? splice site of an intron of interest in a gene of interest to mutate into AA, or to induce GT at a 5? splice site of the intron of interest in a gene of interest to mutate to AT, or to induce a plurality of Cs in a polypyrimidine region of the intron of interest in a gene of interest to respectively mutate into Ts. The method specifically blocks an exon recognition process, modulates a selective splicing process of endogenous mRNA, induces exon skipping, activates an alternative splice site, induces mutually exclusive exon conversion, induces intron retention, and enhances an exon.

  • Publication number: 20120178081
    Abstract: Methods of detecting nucleic acids, proteins and cells including methods of detecting two or more nucleic acids, proteins and cells in multiplex bDNA assays, are provided. Assays may be conducted at least in vitro, in vivo, in cellulo, and in situ. Nucleic acids are detected, through cooperative hybridization that results in specific association of a label probe system with target nucleic acids. Embodiments are directed to concurrent detection of one or more nucleic acids and/or one or more proteins. The detected proteins may be intracellular or external markers on the surface of the cell. Detection of protein components is accomplished by use of specific antibodies and a label probe system and/or coated microparticles which bind to the outside surface of specific cells and contain specific probes that can be detected using the same label probe system. Compositions, kits, and systems related to the methods are also described.
