Methods for enhancing or decreasing the levels of MIR124 and MIR29 in subjects with muscular dystrophy

摘要

Disclosed herein are methods of treating and diagnosing muscular dystrophy. In some examples, the methods include treating muscular dystrophy by administering to the subject a therapeutically effective amount of an agent that alters the expression of at least one miR gene product, such as miRNA-124 and/or miRNA-29 thereby treating muscular dystrophy. In one particular example, the method of treatment includes administering an agent that decreases the expression or activity of miRNA-124. In another embodiment, the method of treatment includes administering a composition that includes one or more agents to decrease the expression and/or activity of miRNA-124 and one or more agents to alter the activity of miRNA-29 (increase or decrease). Also disclosed are methods of enhancing muscle regeneration, repair, or maintenance in a subject and methods of enhancing α7β1 integrin expression. Methods of prospectively preventing or reducing muscle injury or damage in a subject are also disclosed.
