The nos. represent the fold change of gene expression after d3, d5, and d7 of mechanical overload compared with control non-overloaded muscles. Italicized numbers mean that the fold change in gene expression is either lower than 50% decrease or lower than 2-fold increase. The selected genes were differentially expressed (twofold increase or 50% decrease) at least one time between d3 and d7.
