Abstract: Provided herein are modified DNAzymes, including DNAzymes with overhang sequences not complementary to the target RNA, in particular, overhangs with high G content. Also provided are compositions comprising the DNAzyme; vectors including the DNAzymes; pharmaceutical compositions including the vectors; and methods including any of the above for cleaving a target RNA; inducing cell death; and treating various diseases and disorders.

Abstract: Provided herein are compositions and methods comprising a DNAzyme targeting a transcript encoding a cell wall synthesis enzyme, for use in reducing an amount of a biofilm in a subject with a bacterial infection; increasing or enhancing antibiotic susceptibility in a subject with a bacterial infection; and inhibiting bacterial growth in a subject with a bacterial infection.

Abstract: The present disclosure describes compositions and methods for selection functional aptamers. In certain embodiments, provided herein are methods of using aptamer cluster-containing particles to identify functional aptamers from an aptamer library. In certain embodiments, provided herein are functionally enriched populations of aptamers. In certain embodiments, provided herein are methods for selecting an aptamer for use in personalized cancer treatment and methods for preparing a tumor delivery system. In certain embodiments, provide herein are compositions comprise the aptamer cluster-containing particles, target cells (e.g., cancer cells, immune cells, etc.) and/or a detectable indicator of cellular function (e.g., a fluorescent indicator of apoptosis, cell proliferation, gene or protein expression, etc.).

Abstract: The present disclosure describes compositions and methods for rapid selection of both binding and functional oligonucleotides (DNA, RNA, or any natural or synthetic analog of these). In certain embodiments, provided herein are flow cells (e.g., flow cells for an Illumina sequencing instrument or a Polonator sequencing instrument) comprising within its flow chamber a plurality of immobilized aptamer clusters (e.g., from an aptamer library described herein) and, optionally, one or more target cells (e.g., cancer cells, immune cells, etc.) and/or a detectable indicator of cellular function (e.g., a fluorescent indicator of apoptosis, cell proliferation, gene or protein expression, etc.). In certain embodiments, provided herein are methods of using such an aptamer cluster-containing flow cell to identify functional aptamers from an aptamer library (e.g., in a sequencing instrument, such as an Illumina sequencing instrument).

Abstract: The present disclosure describes methods and compositions for the treatment of rapidly evolving biological entities (e.g., cancer cells, bacteria, virus, etc.) using therapeutic nucleic acids.

Abstract: The present invention provides to a set of anti-pathogenic nucleic acids capable of forming in cellulo one or more nucleic acid origami nanostructure together with one or more pathogenic RNA such as ribosomal RNA, pre-rRNA or mRNA present in the pathogenic cells. The present invention further provides nucleic acid constructs comprising the sequences of the set of anti-pathogenic staple nucleic acids and a vector comprising such a nucleic acid construct. Compositions, including pharmaceutical compositions, comprising the sets, the construct or the vector and use thereof are provided as well.
