Josh Allen, BS '08, makes Forbes 30 under 30 list!

Josh Allen (BS Chemistry, 2008) has been named one of 2016’s Forbes 30 under 30 for healthcare. Josh parlayed his experience at GT into a PhD in Biochemistry and Molecular Biophysics from the University of Pennsylvania where he discovered ONC201 as a novel first-in-class anticancer agent. He is currently the Vice President of Research and Development at Oncoceutics.

Protein dynamics are essential in regulating nearly every cellular event, and aberrant proteostasis is the source of many diseases. It is extraordinarily difficult to globally study protein dynamics and accurately measure their half-lives. Here we have developed a chemical proteomics method integrating protein labeling, click chemistry and multiplexed proteomics, which overcomes current challenges with existing methods. Labeling with both azidohomoalanine (AHA) and heavy lysine allows us to selectively enrich newly synthesized proteins, clearly distinguish them from existing proteins, and reduce the impact of heavy amino acid recycling. Moreover, multiplexed proteomics enables us to quantify proteins at multiple time points simultaneously, thus increasing the accuracy of measuring protein abundance changes and their half-lives. Systematic investigation of newly synthesized protein dynamics will provide insight into proteostasis and the molecular mechanisms of disease.
