General effects of glucocorticoids on dysregulated genes during MG. (A) Eight K-median clustering analysis was applied to the median of ratios of the 3 comparisons: adult controls–reference (A ctrl), untreated MG patients–reference (MG), and treated MG patients–reference (MG-t) for the 384 dysregulated genes in MG extracted with SAM with an FDR less than 5% and an FC more than 1.8. The white circles represent average expression levels. (B) Numbers of dysregulated genes obtained in the microarray analysis data.
