Effect of cutoff value on enrichment analysis result. The left and the right panel show the enrichment of Msn2/Msn4 and Gis1 in the up-regulated gene set in three long-lived mutants. The x-axis is the threshold for up-regulation. The y-axis is the negative log transformed p-value. The red, green, and blue line correspond to sch9Δ, ras2Δ, and tor1Δ mutant, respectively.
