Abstract: The present invention provides oligonucleotides with chemical motifs that are miR-145 inhibitors. The oligonucleotides can be used for the treatment and prevention of a condition by inhibiting the expression or activity of miR-145 in cells of a subject in need thereof. Methods provided include treating or preventing pulmonary arterial hypertension, neointima formation, restenosis or hypertension in a subject in need thereof by administering to the subject an inhibitor of miR-145 expression or activity. Pharmaceutical compositions and kits comprising miR-145 inhibitors are also disclosed.

Abstract: Disclosed herein are a collection of miRNAs and genes whose expression is altered in hypertrophic cardiomyopathy. Accordingly, these miRNAs and genes, singly or in combination, are useful as molecular markers for diagnosis or prognosis of hypertrophic cardiomyopathy. The miRNAs and genes disclosed can also be therapeutic targets for cardiac hypertrophy. For example, agents such as miRNA mimics, miRNA inhibitors or siRNAs for a given miRNA or gene can be used to modulate the level of these molecules thereby inhibiting or preventing hypertrophic cardiomyopathy.
