Systems biology signal pathways

For large-scale analysis, this strategy has been further modified for use in the array method (Ito et al., 2000 Uetz et al., 2000 Walhout et al., 2000). Such analyses in Sachromyces cerevisiae and Caenorhabditis elegans have already reported many potential interactions that need to be confirmed by further biological experimentation. Finally, another modification of the yeast two-hybrid system has been recently reported, termed reverse two-hybrid (Vidal and Endoh, 1999). This technique is being used to identify compounds and peptides that can disrupt protein-protein interactions and thus have an effect on various signaling pathways.
