  sub:_6 prov:value """HCPTPA overexpression inhibits VEGFinduced VEGFR2 autophosphorylation, EC migration,
and proliferation (46). High cell density-enhanced PTP1 (DEP- 1)/CD148 attenuates
phosphorylation of VEGFR2 in contact-inhibited confluent ECs (40). A small
molecule inhibitor of PTP1B enhances VEGF-induced VEGFR2 autophosphoryla- tion,
migration, and proliferation of EC, as well as neovascularization in a mouse matrigel
model (92). Angiopoietin-1 stimulates association of SHP-2 to the phosphorylated
Tie-2 receptor (47), which in turn inhibits PI3 kinase-dependent signaling
pathways leading to EC migration.""" ;
