Caffeine effect on adenosine deaminase catalysis: A new look at the effect of caffeine on adenosine deaminase activity
The effect of physiological concentrations of caffeine (purified from Persian tea) on adenosine deaminase (ADA) activity at physiological and pathological concentrations of adenosine (as substrate) in 50 mM Tris-HCl buffer (pH 7.3) at 37°C was investigated, using UV-VIS spectroscopy. ADA exhibited a bi-phasic activity behavior and both phases showed positive cooperativities indicating adenosine...

متن کاملAdenosine deaminase (ADA) isoenzymes ADA1 and ADA2 in biological fluids.
We read with great interest the editorial by GAKIS [1] about the extreme importance of the adenosine deaminase (ADA) isoenzymes ADA1 and ADA2 on the homeostasis of 2' deoxyadenosine and adenosine, especially when monocytes and macrophages are infected by intracellular microorganisms. Serum ADA activity is increased in various conditions such as liver disease, tuberculosis, typhoid, infective mo...
متن کاملADENOSINE DEAMINASE ACTIVITY IN ESTROGEN RECEPTOR POSITIVE AND NEGATIVE HUMAN BREAST CANCER CELL LINES
ABSTRACT Background: The aims of this study were to assay the activity of adenosine deaminase (ADA) in estrogen receptor positive (MCF-7) and negative (MDA-MB468) breast cancer cell lines. Methods: MDA-MB468 and MCF-7 breast cancer cell lines were cultured in complete medium, striped serum with and without 0.0 1~-LM diethylstilbestrol (DES), complete medium in the presence and absence of 111M ...
