Pharmacoproteomics Research Articles

Experimental workflows in proteomics approaches to drug screening and development, like genomics approaches, may be broadly classified as targeted or global. Targeted approaches may involve affinity-based or activity-based profiling techniques, which employ chemically-engineered probes to capture proteins of interest. While global methods are more challenging from a bioinformatics standpoint, they are advantageous because they provide unbiased, large-scale analyses and may reveal unexpected relationships among seemingly unrelated pathways. A typical in vitro workflow involves treating cells with the drug of interest, lysing the cells, digesting proteins into peptides, and then analyzing the entire proteome by mass spectrometry techniques. Drug failure is often due to poor pharmacokinetic properties such as low bioavailability, poor absorption, pre-mature metabolism, or adverse side effects. 
Pharmacoproteomics gives us the potential to study drug mechanisms at the proteome level while at the same time investigating toxicity and resistance, or perhaps discovering new drug targets, early in the drug development process. In this manner, drugs with flawed properties can be saved from further development, while newer, better-performing drugs can be discovered and moved forward.
