title: Cobalt-activated acylase and aminoacylase I in human malignant tumors.
abstract: The activities and isoenzyme pattern of cobalt-activated acylase and of aminoacylase I were estimated in carcinomas of bronchi, lung, thorax, stomach, colon and uterus. In all cancer tissues the activity of cobalt-activated acylase was markedly increased as compared with the normal tissue. Alterations of the isoenzyme pattern of cobalt-activated acylase were found in the carcinoma of stomach and of uterus, with the increased expression of the form-1 of the enzyme. No regularity in the aminoacylase I changes in tumor tissues has been observed.
