Activities of adenosine deaminase, 5′-nucleotidase, guanase, and cytidine deaminase enzymes in cancerous and non-cancerous human breast tissues

Abstract

We measured activities of some DNA turnover enzymes in 9 breast tissues with stage II cancer, 6 breast tissues with stage IIIa cancer, and 9 non-cancerous adjacent breast tissues from the same patients with stage II cancer. We found higher Adenosine Deaminase (ADA) and 5′-Nucleotidase (5′NT) and lower Guanase (GUA) activities in the cancerous tissues… (More)
