1 L-citrulline (Cit) is a co-product of NO synthesis and a direct L-arginine (Arg) precursor for de novo NO synthesis. Citrulline citron rho-interacting serine/threonine kinase Rattus norvegicus
2 L-citrulline (Cit) is a co-product of NO synthesis and a direct L-arginine (Arg) precursor for de novo NO synthesis. Arginine citron rho-interacting serine/threonine kinase Rattus norvegicus
3 L-citrulline (Cit) is a co-product of NO synthesis and a direct L-arginine (Arg) precursor for de novo NO synthesis. Arginine citron rho-interacting serine/threonine kinase Rattus norvegicus
4 Acute liver failure (ALF) is associated with increased nitric oxide (NO) and cyclic GMP (cGMP) synthesis in the brain, indirectly implicating a role for active transport of Cit. Cyclic GMP citron rho-interacting serine/threonine kinase Rattus norvegicus
5 In the present study we characterized [(3)H]Cit uptake to the cortical brain slices obtained from control rats and rats with thioacetamide (TAA)-induced ALF ("TAA slices"). Thioacetamide citron rho-interacting serine/threonine kinase Rattus norvegicus
6 Cit uptake was not affected by Arg, the y(+)/y(+)L transport system substrate, nor by amino acids taken up by systems A, xc (-)or XAG. Arginine citron rho-interacting serine/threonine kinase Rattus norvegicus
7 The activity of argininosuccinate synthase (ASS) and argininosuccinate lyase (ASL), the two enzymes of Cit-NO cycle catalyzing synthesis of Arg, showed an increase in TAA rats, consistent with increased ASS and ASL protein expression, by ~30 and ~20 %, respectively. Arginine citron rho-interacting serine/threonine kinase Rattus norvegicus
