Enrichment analysis of biologically modulated pathways. Analysis first shows a significant enrichment in TGFbeta signaling modulated by SMAD proteins: as the majority of genes are down-regulated, we have inhibition of this pathway in Saos clones, with an effect that increases over time. Other important and significantly modulated are the EMT and Apoptotic pathways. (min (p-value) = most significant p-value among the 3 time points after multiple correction test)
