Epithelial arginase-1 is a key mediator of age-associated delayed healing in vaginal injury
Pelvic organ prolapse is a disorder that substantially affects the quality of life of millions of women worldwide. The greatest risk factors for prolapse are increased parity and older age, with the largest group requiring surgical intervention being ...

Liver-specific knockout of arginase-1 leads to a profound phenotype similar to inducible whole body arginase-1 deficiency. [PDF]
Arginase-1 (Arg1) converts arginine to urea and ornithine in the distal step of the urea cycle in liver. We previously generated a tamoxifen-inducible Arg1 deficient mouse model (Arg1-Cre) that disrupts Arg1 expression throughout the whole body and leads to lethality ≈ 2 weeks after gene disruption.

Aim: Hepatic ischemia-reperfusion (HIR) induces remote organs injury, including the brain. The homeostasis of the brain is maintained by the blood-brain barrier (BBB); thus, we aimed to investigate whether HIR impaired BBB and attempted to elucidate its ...

Phenotypic pleiotropy in arginase deficiency: A single center cohort
Background: Arginase deficiency is considered a masquerader of diplegic cerebral palsy. The rarity of hyperammonemic crisis and the slowly progressive course has made it a unique entity among the urea cycle defects. Objectives: The aim of our study is to

Identification of ARG1 Mutations in Patients with Arginase 1 Deficiency
Introduction: Argininemia is an autosomal recessive uncommon metabolic condition, caused by mutations in arginase enzyme. Variable clinical symptoms of argininemia might bring about a delayed diagnosis. In order to prove an argininemia condition, a genetic test result is needed. This study aims to describe two cases of argininemia homozygote mutations.

Lethal phenotype in conditional late-onset arginase 1 deficiency in the mouse. [PDF]
Human arginase deficiency is characterized by hyperargininemia and infrequent episodes of hyperammonemia, which lead to neurological impairment with spasticity, loss of ambulation, seizures, and severe mental and growth retardation; uncommonly, patients suffer early death from this disorder.

Arginase activity - a marker of disease status in patients with visceral leishmaniasis in ethiopia. [PDF]
The underlying mechanisms resulting in the profound immune suppression characteristic of human visceral leishmaniasis (VL) are not fully understood. Here, we tested the hypothesis that arginase, an enzyme associated with immunosuppression, is higher in ...

Arginase from kiwifruit: properties and seasonal variation [PDF]
The in vitro activity of arginase (EC 3.5.3.1) was investigated in youngest-mature leaves and roots (1-3 mm diameter) of kiwifruit vines (Actinidia deliciosa var. deliciosa) during an annual growth cycle, and enzyme from root material partially purified.

Local increase of arginase activity in lesions of patients with cutaneous leishmaniasis in Ethiopia. [PDF]
BACKGROUND: Cutaneous leishmaniasis is a vector-borne disease that is in Ethiopia mainly caused by the parasite Leishmania aethiopica. This neglected tropical disease is common in rural areas and causes serious morbidity.

Cytotoxicity of tumor antigen specific human T cells is unimpaired by arginine depletion. [PDF]
Tumor-growth is often associated with the expansion of myeloid derived suppressor cells that lead to local or systemic arginine depletion via the enzyme arginase.
