Proteomic profiling of endorepellin angiostatic activity on human endothelial cells.

ABSTRACT:

Background

Endorepellin, the C-terminal domain V of the heparan sulfate proteoglycan perlecan, exhibits powerful and targeted anti-angiogenic activity on endothelial cells. To identify proteins involved with endorepellin anti-angiogenic action, we performed an extensive comparative proteomic analysis between vehicle- and endorepellin-treated human endothelial cells.

Results

Proteomic analysis of endorepellin influence on human umbilical vein endothelial cells identified five differentially expressed proteins, three of which (beta-actin, calreticulin, and chaperonin/Hsp60) were down-regulated and two of which (vimentin and the beta subunit of prolyl 4-hydroxylase also known as protein disulfide isomerase) were up-regulated in response to endorepellin treatment-and associated
