An antisense compound for use in treating myotonic dystrophy DM1 or DM2, a method of enhancing antisense targeting to heart and quadricep muscles, and a method for treating DM1 or DM2 in a mammalian subject are disclosed. The oligonucleotide has 8-30 bases, with at least 8 contiguous bases being complementary to the polyCUG or polyCCUG repeats in the 3′UTR region of dystrophia myotonica protein kinase (DMPK) mRNA in DM1 or DM2, respectively. Conjugated to the oligonucleotide is a cell-penetrating peptide having the sequence (RXRR(B/X)R)₂XB, where R is arginine; B is β-alanine; and each X is —C(O)—(CH₂)_n—NH—, where n is 4-6. The antisense compound is effective to selectively block the sequestration of muscleblind-like 1 protein (MBNL1) and/or CUGBP, in heart and quadricep muscle in a myotonic dystrophy animal model.

Provided are tricyclo-DNA (tc-DNA) AON and methods employing tc-DNA AON for modifying splicing events that occur during pre-mRNA processing. Tricyclo-DNA (tc-DNA) AON are described that may be used to facilitate exon skipping or to mask intronic silencer sequences and/or terminal stem-loop sequences during pre-mRNA processing and to target RNase-mediated destruction of processed mRNA. Tc-DNA AON described herein may be used in methods for the treatment of Duchenne Muscular Dystrophy by skipping a mutated exon 23 or exon 51 within a dystrophin gene to restore functionality of a dystrophin protein; in methods for the treatment of Spinal Muscular Atrophy by masking an intronic silencing sequence and/or a terminal stem-loop sequence within an SMN2 gene to yield modified functional SMN2 protein, including an amino acid sequence encoded by exon 7, which is capable of at least partially complementing a non-functional SMN1 protein; and in methods for the treatment of Steinert's Myotonic Dystrophy by targeting the destruction of a mutated DM1 mRNA comprising 3′-terminal CUG repeats.

In certain embodiments, the present invention provides compositions and methods for treating myotonic dystrophy.

The invention provides rationally designed multi-targeting therapeutic agents for myotonic dystrophy type 1 (DM1), an incurable neuromuscular disease that originates in an abnormal expansion of CTG repeats (CTG^exp) in the DMPK gene. The rationally designed small molecules target the DM1 pathobiology in three distinct ways: (1) binding the expanded trinucleotide repeat, CTG^exp, and inhibiting its transcription to the toxic CUG^exp RNA, (2) binding the CUG^exp RNA and releasing sequestered muscleblind-like protein (MBNL1), and (3) cleaving the toxic CUG^exp in an RNase-like manner. Importantly, the compounds can reduce the levels of CUG^exp in DM1 model cells and reverse two separate CUG^exp-induced phenotypes of DM1.

The disclosure features compositions and methods for the treatment of disorders associated with improper ribonucleic acid (RNA) splicing, including disorders characterized by nuclear retention of RNAtranscripts containing aberrantly expanded repeat regions that bind and sequester splicing factor proteins. Disclosed herein are interfering RNA constructs that suppress the expression of RNA transcripts containing expanded repeat regions, as well as viral vectors, such as adeno-associated viral vectors, encoding such interfering RNA molecules. For example, the disclosure features interfering RNAmolecules, such as siRNA, miRNA, and shRNA constructs, that anneal to dystrophia myotonica protein kinase (DMPK) RNA transcripts and attenuate the expression of DMPK RNA containing expanded CUG trinucleotide repeats. Using the compositions and methods described herein, a patient having an RNA dominance disorder, such as a human patient having myotonic dystrophy, among other conditions described herein, may be administered an interfering RNA construct or vector containing the same so as to reduce the occurrence of spliceopathy in the patient, thereby treating an underlying etiology of the disease.
