PURPOSE Proinflammatory signaling mechanisms are implicated in the induction of retinal neovascularization (NV) during ischemic retinopathies. This study examined transcription factor (TF) AP-1, HIF-1, and NF-kappaB DNA-binding in relation to cyclooxygenase (COX)-2 and VEGF RNA and protein levels in hypoxia-triggered monkey choroidal retinal (RF/6A)(More)
Rat proenkephalin was overexpressed in Chinese hamster ovary cells using the dihydrofolate reductase-coupled genetic amplification method. About 2 mg purified protein could be obtained from 250 ml conditioned medium; multiple successive harvests could be obtained from the same roller bottle. Degradation of proenkephalin released into the conditioned medium(More)
PURPOSE To determine whether the gene expression of matrix metalloproteinases (MMPs) as well as that of the pro-angiogenic cytokine vascular endothelial growth factor (VEGF) and its receptors change in response to hypoxic exposure in a primate choroid-retinal endothelial cell line, and furthermore, whether cytosolic phospholipase A2 (cPLA2) plays a role in(More)
Four human B cell lines established by Epstein-Barr viral transformation of B cells from a patient with a clinical diagnosis of Alzheimer's disease (AD) were found to secrete antibodies that react with plaques and cerebrovascular blood vessels in AD brain in a staining profile characteristic of beta-amyloid protein (beta-AP) in AD brain. Two of these(More)
