Because it has been recently shown that the neurotransmitter dopamine at pharmacological dose can inhibit VEGF\/VPF-mediated microvascular permeability, proliferation, and migration of endothelial cells in vitro, we therefore hypothesized that endogenous dopamine may regulate the actions of VPF\/VEGF in vivo. We report that VPF\/VEGF-induced phosphorylation of VEGF receptor 2, focal adhesion kinase, and MAPK in the endothelial cells is strikingly increased in both dopamine-depleted and dopamine D<jats:sub>2<\/jats:sub> receptor knockout mice compared with normal controls, thereby indicating that endogenous dopamine regulate these critical signaling cascades required for the in vivo endothelial functions of VPF\/VEGF. Together, these observations provide new mechanistic insight into the dopamine-mediated inhibition of the activities of VPF\/VEGF and suggest that endogenous neurotransmitter dopamine might be an important physiological regulator of VPF\/VEGF activities in vivo. <\/jats:p>","DOI":"10.1152\/ajpheart.00272.2004","type":"journal-article","created":{"date-parts":[[2004,9,15]],"date-time":"2004-09-15T21:12:50Z","timestamp":1095282770000},"page":"H1554-H1560","source":"Crossref","is-referenced-by-count":80,"title":["Dopamine in vivo inhibits VEGF-induced phosphorylation of VEGFR-2, MAPK, and focal adhesion kinase in endothelial cells"],"prefix":"10.1152","volume":"287","author":[{"given":"Chandrani","family":"Sarkar","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Debanjan","family":"Chakroborty","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rita Basu","family":"Mitra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samir","family":"Banerjee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Partha Sarathi","family":"Dasgupta","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sujit","family":"Basu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"24","reference":[{"key":"R1","doi-asserted-by":"publisher","DOI":"10.1084\/jem.20021408"},{"key":"R2","doi-asserted-by":"publisher","DOI":"10.1016\/0165-5728(95)00044-3"},{"key":"R3","doi-asserted-by":"crossref","unstructured":"Basu S, Nagy JA, Pal S, Vasile E, Eckelhoefer IA, Bliss S, Manseau EJ, Dasgupta PS, Dvorak HF, and Mukhopadhyay D.
