neoplasm
• presence of nests of dysplastic cells are seen in the ovaries of newborn mice and E20.5, but not E18.5, indicating that tumor growth begins perinatally
• females develop ovarian granulosa cell bilateral tumors with 100% penetrance from an early age
• 100% penetrance of aggressive testicular cancer
• tumors are first observable at 5 weeks of age, and by 3 months of age, about 70% of mice have unilateral testicular tumors and 30% have bilateral tumors
• tumors exhibit characteristics of granulosa cell tumors of the testis and not Sertoli cell tumors
• metastasis is not observed, but this might be that mice do not have sufficient time to develop metastasis due to early lethality, however, when granulosa cell tumors are removed at 6 weeks of age, mice show development of large lung metastases 6-16 weeks later, indicating that tumors indeed are metastatic (J:142150)
• 44% of mice develop pulmonary metastases by 4 months (J:149060)

reproductive system
• seminiferous tubule degeneration is seen by 3 weeks of age
• presence of nests of dysplastic cells are seen in the ovaries of newborn mice and E20.5, but not E18.5, indicating that tumor growth begins perinatally
• females develop ovarian granulosa cell bilateral tumors with 100% penetrance from an early age
• 100% penetrance of aggressive testicular cancer
• tumors are first observable at 5 weeks of age, and by 3 months of age, about 70% of mice have unilateral testicular tumors and 30% have bilateral tumors
• tumors exhibit characteristics of granulosa cell tumors of the testis and not Sertoli cell tumors

endocrine/exocrine glands
• seminiferous tubule degeneration is seen by 3 weeks of age
• presence of nests of dysplastic cells are seen in the ovaries of newborn mice and E20.5, but not E18.5, indicating that tumor growth begins perinatally
• females develop ovarian granulosa cell bilateral tumors with 100% penetrance from an early age
• 100% penetrance of aggressive testicular cancer
• tumors are first observable at 5 weeks of age, and by 3 months of age, about 70% of mice have unilateral testicular tumors and 30% have bilateral tumors
• tumors exhibit characteristics of granulosa cell tumors of the testis and not Sertoli cell tumors
