    摘要: Methods, systems, compositions and kits for detection of multiple analytes are disclosed. The methods, systems, compositions and kits may comprise an oligonucleotide that may bind to more than one analyte. The oligonucleotide may allow for the generation of different signal depending on the analyte that the oligonucleotide is hybridized to. The signals generated from may be used to identify the presence of an analyte. The signals generated from may be used may be used to simultaneously identify the presence of multiple analytes in a sample.

    摘要: Provided herein are formulations configured for the oral delivery of a nucleic acid, such as a non-coding RNA. The formulations provided for herein comprise a plurality of cationic lipids used to encapsulate the nucleic acid within a micelle and a mixture of casein proteins and chitosan polymers used to coat the lipids, which form a coating on the micelle. The coated micelle lends acid-resistance to the formulation such that oral administration is possible with enhanced bioavailability of the nucleic acid to conditions associated with inflammation or fibrosis, such as hypertrophic myocardiopathy, heart failure with preserved ejection fraction, muscle disorders, such as muscular dystrophy, scleroderma and/or viral infection.

    摘要: An isolated nucleic acid that includes the nucleotide sequence: CGUCCGAUGGUAGUGGGUUAUCAG (SEQ ID NO: 12) is provided. In some embodiment, the nucleic acid includes at least one chemically-modified nucleotide. The nucleic acid and composition containing same find use in treating coniditions associated with inflammation and/or fibrosis, for example, without limitation, heart conditions, such as hypertrophic myocardiopathy, myocardial infarction, and heart failure with preserved ejection fraction; muscle disorders, such as muscular dystrophy; skin disorders, such as scleroderma; and inflammatory conditions, such as autoimmune conditions or inflammatory conditions associated with a viral infection.
