title: Proteomic trajectory mapping of biological transformation: Application to developmental mouse retina.
abstract: In this report we introduce a new concept "proteomic trajectory mapping" for the investigation of a complex phenomenon underlying biological transformation and transition. We define proteomic trajectory to be the kinetic trace of protein expression and present a successful proteomic trajectory mapping of complex molecular events underlying postnatal development of mouse retina. Cluster analysis of the trajectory data using a two-state model identified four proteomic trajectory types: two distinct trajectory types accounting for the decline or the rise of protein molecules actively expressed in the juvenile stage (J-type) or in the adult stage (A-type), a class of transient trajectories that mediate the transformation from the juvenile to the adult stage (T-type), and the steady trajectories throughout the entire process of transformation (C-type). The dominance of particular protein categories expressed in each trajectory characterizes the stage of retinal development. Proteomic trajectory mapping will be a powerful tool to study the systematic changes of protein expression caused by physiological, genetic, or pathological agents and the reverse of such changes to the norm by a treatment. The proteomic trajectory mapping is applicable to any biological transformation and, therefore, will be a powerful tool in biomedical sciences.
