Redox signaling plays an important role in the positive regulation of angiogenesis by vascular endothelial growth factor, but its role in signal transduction by angiogenesis inhibitors is less clear. Using muscle explants in 3D culture, we found that explants from mice lacking the angiogenesis inhibitor thrombospondin-1 (TSP1) exhibit exaggerated angiogenic(More)
We identified a specific interaction between two secreted proteins, thrombospondin-1 and versican, that is induced during a toll-like receptor-3-dependent inflammatory response in vascular smooth muscle cells. Thrombospondin-1 binding to versican is modulated by divalent cations. This interaction is mediated by interaction of the G1 domain of versican with(More)
This paper describes an approach to adhere retinal cells on micropatterned polyelectrolyte multilayer (PEM) lines adsorbed on poly(dimethylsiloxane) (PDMS) surfaces using microfluidic networks. PEMs were patterned on flat, oxidized PDMS surfaces by sequentially flowing polyions through a microchannel network that was placed in contact with the PDMS surface.(More)
The processes that lead from detection of chemicals, transduction, and coding with the appropriate message to initiate ingestion of a palatable meal or to reject a potentially noxious substance are poorly understood in vertebrates owing to the complex organization of the taste system. As a first step in elucidating the cellular basis of the behavioral(More)
PURPOSE To investigate the effects of dexamethasone (DEX) on pigment epithelium-derived factor (PEDF) cDNA and secreted protein in human trabecular meshwork (TM). METHODS Anterior segment organ cultures were perfused with 0.1 microM DEX (OD) and vehicle (OS). Primary human TM cells (HTM) were treated with DEX under similar conditions. PEDF mRNA and(More)
Unlike TSP1, TSP2 is less-to-moderately responsive to serum in mouse NIH3T3 and Swiss 3T3 cells respectively. Transcription of THBS2 in some human cancers is suppressed through hypermethylation. TSP2 mRNA is upregulated by Rac1-induced reactive oxygen species, Hox A5, ACTH, TGFb, cerivastatin and in-vitro, by increasing cell confluency. Downregulation of(More)
