P 195 Increased activity of constitutive nitric oxyde synthase in the porcine ciliary body
نویسندگان
چکیده
pmmSe. The conversion of L-arginine into L-citrulline by nitric oxide synthase (NOS) leads to nitric oxide formation. Two major NOS isoforms exist, a &*-dependent NOS (cNOS) and a &“-independent NOS (iNOS). The cNOS is constitutive of many cells while the iNOS is not expressed in normal conditions but only induced after the stimulation by different factors (endotoxins, cytokines, etc...). This study addresses the spontaneous cNOS and iNOS activity in porcine ocular tissues.

متن کاملComparison of inducible nitric oxide synthase activity in pancreatic islets of young and aged rats
Objective(s):Some pathologic situations such as diabetes and metabolic syndrome are associated with alternation in nitric oxide level. Incidence of these condition increases with aging. On the other hand, insulin secretion is modulated by nitric oxide, and nitric oxide synthase (NOS) activity is also altered in diabetes. In this study, modification in the enzyme activity associated with aging a...
متن کاملConstitutive and permissive roles of nitric oxide activity in embryonic ciliary cells.
Embryos of Helisoma trivolvis exhibit cilia-driven rotation within the egg capsule during development. In this study we examined whether nitric oxide (NO) is a physiological regulator of ciliary beating in cultured ciliary cells. The NO donor S-nitroso-N-acetylpenicillamine (SNAP; 1-1,000 microM) produced a dose-dependent increase in ciliary beat frequency (CBF). In contrast, the nitric oxide s...
