1. From: Hepatocyte Growth Factor Induces Retinal Vascular Permeability via MAP-Kinase and PI-3 Kinase without Altering Retinal Hemodynamics
Invest. Ophthalmol. Vis. Sci ;47(6): doi: /iovs
Figure Legend:
(A) HGF-induced retinal vascular permeability was partially mediated in vivo by PI-3 kinase and MAPK, but not by protein kinase C. The effect of a 10-minute pretreatment with PI-3 kinase inhibitor (LY at 50 μM), MEK-specific inhibitor (PD98059 at 20 μM), or non-isoform-selective protein kinase C inhibitor (GFX at 0.5 μM) on vitreous fluorescein leakage after HGF injection (5 ng/eye) was evaluated. Pretreatment with BSA established the basal (100%) HGF/SF leakage stimulation level. (* P = 0.005; †P = compared with eyes pretreated with BSA and injected with HGF.) (B) HGF/VEGF’s effect on retinal vascular permeability was not additive in vivo. The effect of a 10-minute pretreatment with PI-3 kinase inhibitor (LY at 50 μM) or MEK-specific inhibitor (PD98059 at 20 μM) on vitreous fluorescein leakage after an HGF (5 ng/eye)/VEGF (2 ng/eye) combination injection was evaluated. Pretreatment with balanced saline established basal (100%) leakage stimulation level. (*P < 0.01 compared with eyes pretreated with balanced saline and injected with BSA.)
