Catechol effect on the lysosomal enzymes in the adipose tissues of obese and obese-diabetic monkeys.
The activities of three lysosomal hydrolases were assayed in the basal and isoproterenol-stimulated states in the adipose tissues of lean, obese and obese-diabetic monkeys. The basal activity of acid lipase appeared higher in the obese tissues with or without diabetes than in the lean tissue. Isoproterenol stimulation did not affect these activities. The basal activity of beta-galactosidase (beta-Gal) was similar in all tissues and unaffected by isoproterenol stimulation. Although basal activity of hexosaminidase (Hex) was comparable in all tissues, activity increased significantly in the stimulated diabetic-obese tissue but not in the stimulated tissues from lean animals or animals with simple obesity.
