Arginase as a mediator of diabetic retinopathy [PDF]
Frontiers in Immunology, 2013 We have shown previously that diabetes causes increases in retinal arginase activity that are associated with impairment of endothelial cell (EC)-dependent vasodilation and increased formation of the peroxynitrite biomarker nitrotyrosine.

Methylglyoxal-Modified Albumin Effects on Endothelial Arginase Enzyme and Vascular Function
Cells, 2023 Advanced glycation end products (AGEs) contribute significantly to vascular dysfunction (VD) in diabetes. Decreased nitric oxide (NO) is a hallmark in VD. In endothelial cells, NO is produced by endothelial NO synthase (eNOS) from L-arginine.

Impact of suitable control on a uniform interpretation of units for arginase assay
Biochemistry and Biophysics Reports, 2021 The arginase catalyzes the conversion of arginine into ornithine and urea. The activity of arginase serves as a critical diagnostic marker for several pathophysiological conditions.

Arginase activities and global arginine bioavailability in wild-type and ApoE-deficient mice: responses to high fat and high cholesterol diets. [PDF]
PLoS ONE, 2010 Increased catabolism of arginine by arginase is increasingly viewed as an important pathophysiological factor in cardiovascular disease, including atherosclerosis induced by high cholesterol diets.

Arginase: shedding light on the mechanisms and opportunities in cardiovascular diseases
Cell Death Discovery, 2022 Arginase, a binuclear manganese metalloenzyme in the urea, catalyzes the hydrolysis of L-arginine to urea and L-ornithine. Both isoforms, arginase 1 and arginase 2 perform significant roles in the regulation of cellular functions in cardiovascular system,

SCREENING AND PRODUCTION OF MICROBIAL L-ARGINASE ENZYME AS ANTICANCER AGENT FROM DIFFERENT SOIL ENVIRONMENTS IN EGYPT [PDF]
Ain Shams Medical Journal, 2022 Background: Hydrolysis of L-arginine to L-ornithine and urea is catalyzed by the crucial L-arginase enzyme. L-arginase nowadays is necessary for medicine due to its significance as an anticancer agent against auxotrophic cancers to arginine.
