We present the first study of protein regulation by ligands inCaenorhabditis elegans. The ligands were peptidyl-prolyl isomerase inhibitors of cyclophilins. Up-regulation is observed for several heat shock proteins and one ligand in particular caused a greater than 2-fold enhancement of cyclophilin CYN-5. Additionally, several metabolic enzymes display elevated levels. This approach, using label-free relative quantification, provides an extremely attractive way of measuring the effect of ligands on an entire proteome, with minimal sample pretreatment, which could be applicable to large-scale studies. In this initial study, which compares the effect of three ligands, 54 unique proteins have been identified that are up- (51) or down- (3) regulated in the presence of a given ligand. A total of 431C. elegansproteins were identified. Our methodology provides an intriguing new direction forin vivoscreening of the effects of novel and untested ligands at the whole organism level.
