Immunological identification of cholesterol ester hydrolase in the steroidogenic tissues, adrenal glands and testis.
Monoclonal antibodies were generated against the purified pancreatic cholesterol ester hydrolase (CEH, EC 3.1.1.13) to examine the expression of CEH in various bovine tissues. The presence of CEH isozyme antigenically indistinguishable from pancreatic enzyme in the steroidogenic tissues, adrenal glands and testis has been first demonstrated here using the immunoprecipitation method. These results suggest that CEH isozyme, similar to pancreatic CEH, might be involved in the cholesterol metabolism in the steroidogenic tissue.
