It is known that the chemical and mechanical properties of the extracellular matrix (ECM) regulate cellular behavior. Throughout development, the ECM undergoes extensive proteomic transformations to facilitate tissue growth; however, the regulatory roles of these changes are largely unknown due to the absence of a global proteomic characterization. Previously, there has been a lack of tools available to effectively study the developing ECM proteome (matrisome). As part of my research, I am developing an experimental design that allows for dynamic proteomic analysis of core and matrisome-associated proteins during normal and disrupted mouse forelimb development. Noncanonical amino acid tagging uses methionine analogs to incorporate functional tags into newly synthesized proteins, providing a mechanism to enrich and identify differentially-regulated proteins by mass spectrometry. This experimental technique will be used to determine fluctuations or disruptions in ECM composition during translational stages of development.- Student Profile
