Levels of expression of muscle-enriched microRNAs in the vastus lateralis of mild COPD patients and healthy controls.

<p>Mean values and standard deviation (relative expression) of miR-1 (A) expression was upregulated (**: p<0.01) in the vastus lateralis of mild COPD patients compared to healthy controls, whereas expression levels of miR-133 (B), miR-206 (C), and miR-486 (D) did not differ (n.s., non-significant) in the lower limb muscles between the study groups.
