Samenvatting
Inhibin immunoreactivity was estimated in a number of gonadal and non-gonadal tumors. Dog Sertoli cell tumors and human granulosa cell and Leydig cell tumors contained high concentrations of inhibin-like material. Levels, comparable with those in normal testes and ovaries were detected in human testicular non-seminomas and in ovarian cystadenomas, thecomas and adenofibromas. No activity was found in human testicular Sertoli/Leydig cell tumors and seminomas and in ovarian adenocarcinomas, teratomas and a dysgerminoma. Furthermore, human adrenal cortical tissue (tumor and hyperplastic adrenal) contained inhibin immunoreactivity. No activity was found in human tumors of the stomach, gut, liver, kidney, pancreas and mammary gland or in meningiomas. It is concluded that inhibin is not a good marker for specific gonadal tumors. Inhibin might have intratumor actions a growth or differentiation factor.
