Differential microRNA Expression during Myogenic Progenitor Cell Proliferation and Differentiation

ABSTRACT: MicroRNAs (miRNAs) are important in the regulation of many biological processes such as growth and development. To evaluate the role of miRNAs in skeletal muscle regeneration, global miRNA expression was measured during muscle cell growth and differentiation. Primary cultures of murine myogenic progenitor cells (MPC) were studied for miRNA expression using quantitative PCR-array. During MPC differentiation or proliferation, 139 or 16 miRNAs, respectively, exhibited significant >2-fold changes. Cluster analysis revealed 5 distinct miRNA expression patterns at different stages of differentiation. Fourteen miRNAs exhibiting >10-fold change during differentiation included miR-1, 10b, 96, 98, 133a, 139-5p, 330, 335-3p, 339-5p, 344, 486, 499, 504, and 598. Ten of these miRNAs were located in int
