  • Publication number: 20220220484
    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: 9809847
    Abstract: Disclosed herein are compositions and methods for the processing, amplification and detection of polynucleotides using target-specific oligonucleotides (TSOs). Hybridization of TSOs to target polynucleotides guides target processing into and purification of small target fragments that then can be amplified and detected with high sensitivity and reproducibility. The method is specifically beneficial for highly degraded polynucleotides found in biological samples.
