Comparative proteomic analysis of vehicle- and endorepellin-treated human endothelial cells. Representative 2-D protein profiles from vehicle- and endorepellin-treated endothelial cells are depicted with protein separation according to isoelectric point (pI, x-axis) and molecular weight (kDa, y-axis). Encircled protein spots correspond to the five proteins differentially expressed in response to endorepellin treatment. Compare calreticulin (1), β-actin (2), chaperonin/Hsp60 (3), vimentin (4) and prolyl 4-hydorxylase, β subunit (5), spot intensities in the two sets of samples. The spots under the bracket represent serum albumin by LC-MS/MS.
