A prophylactic or therapeutic agent for an aneurysm comprising a miR-33b inhibiting substance, preferably an antisense oligonucleotide against miR-33b, as an active ingredient.

The present invention provides a compound or a pharmaceutically acceptable salt thereof containing a modified oligonucleotide with a length of 8 to 80 consecutive nucleosides, in which the modified oligonucleotide has a nucleobase sequence containing at least 8 consecutive nucleobases contained in a nucleobase sequence of any one of SEQ ID NOs: 3 to 73. With the compound or a pharmaceutically acceptable salt thereof, it is possible to treat a disease or a condition against which inhibition of CALM2 gene expression by controlling of the CALM2 gene expression is effective (particularly, congenital long QT syndrome).

The present invention provides oligomeric compounds. Certain such oligomeric compounds are useful for hybridizing to a complementary nucleic acid, including but not limited, to nucleic acids in a cell. In certain embodiments, hybridization results in modulation of the amount activity or expression of the target nucleic acid in a cell.

Disclosed herein are compositions and methods for reducing expression of C9ORF72 mRNA and protein in an animal with C9ORF72 specific inhibitors. Also disclosed herein are compositions and methods of selectively inhibiting a C9ORF72 pathogenic associated mRNA variant by administering an antisense compound targeting the region beginning at the start site of exon 1A to the start site of exon 1B of a C9ORF72 pre-mRNA. Such methods are useful to treat, prevent, or ameliorate neurodegenerative diseases in an individual in need thereof. Such C9ORF72 specific inhibitors include antisense compounds.

Disclosed herein are antisense oligonucleotides that are capable of inducing expression of ubiquitin-protein ligase E3A (UBE3A) from the paternal allele in animal or human neurons. The oligonucleotides target the suppressor of the UBE3A paternal allele by hybridization to SNHG14 long non-coding RNA at the 5′-end of UBE3A-AS, which is downstream of SNORD115-45 snoRNA. Also disclosed are pharmaceutical compositions and methods for treatment of Angelman syndrome.

Provided are compounds, methods, and pharmaceutical compositions for reducing the amount or activity of LRRK2 RNA in a cell or animal, and in certain instances reducing the amount of LRRK2 protein in a cell or animal. Such compounds, methods, and pharmaceutical compositions are useful to ameliorate at least one symptom or hallmark of a neurodegenerative disease. Such symptoms and hallmarks include ataxia, neuropathy, and aggregate formation. Such neurodegenerative diseases include Parkinson's disease.

Alternative splicing events in SCN1A gene can lead to non-productive mRNA transcripts which in turn can lead to aberrant protein expression, and therapeutic agents which can target the alternative splicing events in SCN1A gene can modulate the expression level of functional proteins in Dravet Syndrome patients and/or inhibit aberrant protein expression. Such therapeutic agents can be used to treat a condition caused by SCN1A, SCN8A or SCN5A protein deficiency.

Described herein are aptamers capable of binding to human complement component 3 (C3) protein; compositions comprising a C3 binding aptamer with a C3-Protein; and methods of making and using the same.

The present invention provides an antisense oligomer having the base sequence depicted in SEQ ID NO: 26, an antisense oligomer having a base sequence resulting from substitution, deletion, insertion, or addition of 1 to 6 bases in the base sequence depicted in SEQ ID NO: 26, a pharmaceutically acceptable salt thereof, or a pharmaceutically acceptable hydrate thereof, an oligonucleotide conjugate in which the antisense oligomer is bound with a molecule capable of binding to an asialoglycoprotein receptor, and a pharmaceutical composition containing the same.

Provided are oligomeric compounds, methods, and pharmaceutical compositions for DMPK the amount or activity of DMPK RNA in a cell or animal, and in certain instances reducing the amount of DMPK protein in a cell or animal. Such oligomeric compounds, methods, and pharmaceutical compositions are useful to treat type 1 myotonic dystrophy.
