OBJECTIVE Adenosine and nitric oxide (NO) are known as vasodilatators. We investigated adenosine deaminase (ADA) activity and NO concentration in the cerebrospinal fluid (CSF) of patients with subarachnoid hemorrhage (SAH). METHODS Forty patients with SAH and 10 controls were included in the study. Nitrate level and ADA activity were measured in CSF. SAH patients were grouped according to the...
BACKGROUND AND PURPOSE Adenosine A(3) receptors mediate beneficial effects in experimental colitis, but their involvement in enteric neuromuscular functions during bowel inflammation is undetermined. This study investigated the regulatory role of A(3) receptors on colonic motility in the presence of experimental colitis. EXPERIMENTAL APPROACH Colitis was induced in rats by 2,4-dinitrobenzenes...
An unresolved issue regards the role of p73 and p63, the two homologs of the p53 oncosuppressor gene, in normal cells and in tumor development. Specific target genes for each protein need to be identified and characterized in order to understand the specific role of each protein in tumor initiation and progression as well as in oncosuppression and development. We tested whether p63 is implicate...
High levels of adenosine can be measured from the lungs of asthmatics, and it is well recognized that aerosolized 5'AMP, the precursor of adenosine, elicits robust bronchoconstriction in patients with this disease. Characterization of mice with elevated adenosine levels secondary to the loss of adenosine deaminase (ADA) expression, the primary metabolic enzyme for adenosine, further support a r...
The somatic cell hybrid method has been used to study the number and different types of human genes involved in the expression of adenosine deaminase (ADA; adenosine aminohydrolase, EC 3.5.4.4) in normal cells and cells from a patient with ADA-deficient severe combined immunodeficiency disease (SCID). Genetic and biochemical characterization of ADA in SCID and the ADA tissue-specific isozymes i...
adenosine deaminase (ada) is an important regulator of insulin action. the single nucleotide polymorphism (snp) g22a in the ada gene decreases enzymatic activity of ada. the aim of this study was to investigate the relationship between the snp g22a and blood glycemic control, insulin resistance, and obesity of gestational diabetes mellitus (gdm) patients in an iranian population. snp g22a was d...
