  • Patent number: 11492617
    Abstract: In certain embodiments, the present disclosure provides methods comprising contacting a cell with a compound comprising a modified oligonucleotide complementary to a nucleic acid transcript. In certain such embodiments, the modified oligonucleotide does not interact or interacts poorly with a mRNP complex or granule. In certain such embodiments the modifications and/or motifs of the modified oligonucleotide do not promote interaction with a mRNP complex or granule. In certain embodiments, the present disclosure provides methods comprising contacting a cell with a compound comprising a modified oligonucleotide thereby reducing the size or amount of protein aggregation in the cell. In certain such embodiments, the protein aggregate is a mRNP granule. In certain such embodiments, the modifications and/or motifs of the modified oligonucleotide promote interaction with a protein aggregate, such as a mRNP granule, that results in disruption of the protein aggregate.
