DiLeu tagging for protein and phosphorylation quantification in parallel

For the first time, DiLeu tagging has been implemented for protein and phosphorylation quantification in parallel. This process was described in a recent publication by Zhong et al titled Highly multiplexed quantitative proteomic and phosphoproteomic analyses in vascular smooth muscle cell dedifferentiation.

The research team developed a strategy that used 12-plex N,N-dimethyl leucine (DiLeu) isobaric tags together with the DiLeu software tool to globally assess protein expression and phosphorylation changes in smooth muscle cells (SMCs) treated with TGFβ/Smad3 and/or SDF-1α (stromal cell-derived factor).

The goal of this work was to develop insights into the mechanisms of TGFβ regulated SMC dedifferentiation, as well as effective therapeutics for vascular disease.
