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)
Acetylcholine receptor (AChR) binding and AChR modulating antibodies were found with approximately the same frequency (86%) in 349 patients with myasthenia gravis (MG). However, the total yield of positive serological results was significantly improved (90%) by assaying AChR modulating antibodies when AChR binding antibodies were not detected, because in 27(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)
Purkinje cell autoantibodies in sera of six female patients with paraneoplastic cerebellar degeneration (PCD) were investigated by indirect immunofluorescence for immunoglobulin isotype and species specificity. Four patients had gynecologic cancer, one breast cancer and one lymphoma. Control sera from 125 patients were negative for Purkinje cell antibodies(More)
We looked for evidence of expression of the cystic fibrosis transmembrane conductance regulator (CFTR) in non-diseased human ventricle. In rabbit and guinea pig the CFTR current is present in the highest density in subepicardial ventricular myocytes. In the present study, whole-cell patch-clamp was used to determine if a CFTR-like chloride current(More)
The in vivo growth of EL-4 ascites tumor cells in peritoneal cavities of syngeneic (C57BL/6) and allogeneic (DBA/2) mice was monitored by electronic volume analysis. In the growth of EL-4 cells in the C57BL/6 mice, daily decrease in electronic modal cell volume and labeling indices was observed. After day 7, the rejection of EL-4 cells in DBA/2 mice was(More)
