Microarray analysis of circulating miRNAs following acute resistance exercise.

<p>(A) Accuracy of hybridization of miRNA microarray. The levels of very few miRNAs changed by >1.5-fold change at any time. (B) Self-organization map clusters generated using the 843 regulated expression profiles. We specified eight clusters and an algorithm grouped them into discrete clusters. Expression profiles were determined at before, 60 min after (Post 1h), one day after (Post 1d), and three days after exercise (Post 3d), and are designated by black dots from left to right, where Pre is set as 0 in the log₂ ratio between control samples. The thick and thin lines represent the mean expression level and standard deviation, respectively.
