However, given mounting evidence that transcript abundance does not always correlate with translational and post translational events [Citation5,Citation6], increasing our abilities to detect increasingly lower levels of protein and peptides is imperative if proteomics is to be of maximum utility to biomedical and clinical research and we are to be able to capture a true snapshot of the translational events governing cellular regulation. This is particularly important as new therapeutic modalities, such as cellular therapies, aim to target proteins upregulated in tumor tissue (tumor associated antigens, TAA) or the mutated cancer proteins. These approaches ultimately produce data of similar or better quality without the upfront costs of performing a DIA experiment and facilitate the utilization of DIA for a wide range of applications. Mellor, H. R., Bell, A. R., Valentin, J. P. & Roberts, R. R. Cardiotoxicity associated with targeting kinase pathways in cancer.
