Proportion of differentially expressed (DE) genes identified in the present study. A. Venn diagrams representing common (Com.) and specific genes differentially expressed in sea bass scales in response to the treatments (17β-estradiol, E2, and/or genistein, Gen, compared to the corresponding controls at each sampling time 1 day and 5 days), compared to the differential expression in the control groups over time. The number of genes by treatment or time and their respective percentage are shown for two levels of stringency. “DE genes” above the diagram corresponds to the 749 genes differentially expressed at an FDR <0.05. Below the diagram the DE genes (332) differentially expressed with a minimum of 2-fold change are considered (“DE ≥ 2 FC” and FDR < 0.05). 51% of the “DE genes” changed expression only in control scales over time but these changes were of low magnitude (average fold change of 1.9-fold between C1d and C5d) and when the analysis stringency was increased to a minimum of 2-fold change, only 24% of these 332 genes changed expression in the control scales over time. The 254 genes (76%) significantly regulated by E2 or Gen were selected for further analyses. B. Shows the comparison of common/specific DE genes between E2 and Gen at the two stringency levels, FDR <0.05 or ≥2 FC and FDR <0.05 (irrespective of the sampling times). For the number of genes regulated by E2 and/or Gen at each sampling time see Fig. 2B of the associated paper in JSBMB [1].
