Up-regulated genes mostly segregated in Cluster 2 whereas down-regulated genes segregated in Cluster 5. The response to Fsh was further identified as insensitive to trilostane in pairwise comparisons (Limma statistical test, p≤5%). When the information was available, we indicated the response to Lh (1) Sambroni et al., 2013), the testicular expression profile as well as the in vivo regulation by androgens ((2)Rolland et al., 2009 and (3) Rolland et al., 2013). -: not determined.
