Analysis of microRNA (miRNA) expression during human skeletal muscle cell differentiation. A: intensity (log₂Hy3) scatter plot showing comparison of miRNA expression between undifferentiated (day 0) and differentiated (day 10) human skeletal muscle cells. The miRNAs that are the focus of our network analyses are highlighted in red and identified by the respective labels. Line (x = y). B: heat map of miRNAs with altered expression during skeletal muscle cell differentiation by SAM time-course analysis [false discovery rate (FDR) < 5%, fold change 1.2 cut-off; n = 5–6].
