Liver and stomach histology of Inhatm1Bay/Inhatm1Bay mice

neoplasm
• derived from the adrenal cortex and observed in 99% of gonadectomized mice (J:20450)
• gonadectomy causes adrenal tumorigenesis which is dependent on the chronically elevated gonadotropin levels that result from this manipulation (J:125349)
• adrenal tumors originate in the subcapsular stem/progenitor zone of the adrenal cortex where upon gonadectomy cells express markers indistinguishable from tumorigenic granulose cells from the ovaries (J:125349)
• the 50% survival rate of female mice with gonadectomies is 22 weeks with all mice dying of extensive adrenal tumor burden (J:125349)
• gonadal stromal tumors, developing around 4 weeks of age with 100% penetrance in both males and females
• ovarian tumors were either mixed or incompletely differentiated gonadal stromal tumors and either bilateral or unilateral (J:3315)
• ovary tumors result from uncontrolled proliferation by granulosa cells (J:125349)
• continuously expanding clusters of tumor cells in the ovary ablate normal ovarian architecture by 2 months of age (J:125349)
• these tumorigenic granulosa cells contain high levels of phosphorylated Smad3 (J:125349)
• histological analysis indicates the presence of large, hemorrhagic tumors that lie adjacent to remnants of seminiferous tubules
• testicular tumors result from uncontrolled proliferation of Sertoli cells
• these tumorigenic Sertoli cells contain high levels of phosphorylated Smad3

cellular

digestive/alimentary system
• mucosal atrophy in the glandular stomach

reproductive system
• hemorrhaging evident at 7 to 16 weeks of age
• massive proliferation of Sertoli cells progresses to testicular tumors by 2 months of age
