  • Patent number: 11319538
    Abstract: Wound healing is a complex homeostatic process in which several distinct types coordinate to repair a physical damage. Failure to close wounds contributes to the pathology of conditions like diabetes mellitus, particularly in the elderly. Presented herein are molecules, pharmaceutical compositions, and methods for applying small RNA oligonucleotide technology to wound healing. Small RNA oligonucleotide approaches as disclosed herein provide a therapeutic strategy for improving both basal and pathological wound healing.

  • Patent number: 10870850
    Abstract: Aspects of the present invention include the production and use of chemically modified RNAi agents (e.g., shRNAs) in gene silencing applications. The chemically modified RNAi agents disclosed herein have reduced immunostimulatory activity, increased serum stability, or both, as compared to a corresponding RNAi agent not having the chemical modification. Compositions containing chemically modified RNAi agents according to aspects of the present invention (including pharmaceutical compositions) and kits containing the same are also provided.

  • Patent number: 10041107
    Abstract: Currently, the circularization of small RNAs is broadly regarded as an obstacle in ligation-related assays and explicitly avoided while short lengths of linear RNA targets is broadly recognized as a factor limiting use of conventional primers in PCR-related assays. In contrast, the disclosed invention capitalizes on circularization of small RNA targets or their conjugates with oligonucleotide adapters. The circular RNA templates provide amplification of the target sequences via synthesis of multimer nucleic acids that can be either labeled for direct detection or subjected to PCR amplification and detection. Structure of small circular RNAs and corresponding multimeric nucleic acids provide certain advantages over current methods including flexibility in design of conventional RT and PCR primers as well as use of 5?-overlapping dimer-primers for efficient and sequence-specific amplification of short target sequences.

  • Patent number: 9816130
    Abstract: Methods, compositions, and kits comprising target-specific oligonucleotides (TSOs) are disclosed herein. Methods, compositions, and kits comprising target-specific oligonucleotides (TSOs) can be used to attach adapters and/or linkers to target RNAs. Methods, compositions, and kits comprising target-specific oligonucleotides (TSOs) can be used in reactions, including, but not limited to, ligation reactions, amplification reactions, and sequencing reactions. Additionally, methods, compositions, and kits comprising target-specific oligonucleotides (TSOs) can be used for reducing and/or preventing the formation of secondary structures in target RNAs. These methods, compositions, and kits can also find use in a number of applications, for example, any application that benefits from stabilizing primary RNA structure, such as detecting and quantifying target RNAs in a sample, in the construction of small RNA libraries, in microarray and RT-qPCR applications, etc.

  • Publication number: 20070105108
    Abstract: The invention provides allosterically regulatable polynucleotides capable of target-dependent circularization and topological linkage to a target nucleic acid molecule. Polynucleotides of the invention include a target binding sequence and a regulatory element which prevents circularization in the absence of the target binding. Polynucleotides may include a catalytic domain, allowing circularization to proceed via catalysis when the target binding sequence of the polynucleotide is bound to the target. Topologically linked polynucleotides may be used for detection of target molecules or to inhibit transcription or translation of the target.

  • Publication number: 20060074041
    Abstract: The present invention is directed to novel nucleic acid molecules and methods for their use. More specifically, the novel nucleic acid molecules of the present invention are capable of tightly and specifically interacting with a target molecule of interest not only through standard Watson-Crick base pairing, but also through additional features which allow the antisense molecules to become topologically “locked” onto the target nucleic acid, thereby imparting improved transcription and translation inhibitory properties.
