neoplasm
• in 7 of 11 continuously mated females with tumor latency ranging from 6 to 24 months compared to control mice that do not develop tumors some tumors show lymphocyte invasion
• tumors are invasive carcinomas that include solid tubular carcinomas, tubular carcinomas and carcinomas with sarcomatous changes
• tumors display ductal enlargement that may or may not be pre-existing

endocrine/exocrine glands
• involution is delayed at I2, I5, and I16
• apoptosis levels peak at day 5 of involution compared to day 2 in wild-type mice
• apoptosis in the alveoli and ducts is delayed and fewer cells undergo apoptosis
• during involution after weaning, mice display enlarged ducts
• after involution ducts remain enlarged
• nonvirgin females exhibit 90% enlarged ducts compared to 40% in nonvirgin control mice and virgin mice exhibit 50% enlarged ducts compared to 30% in virgin control mice
• in 7 of 11 continuously mated females with tumor latency ranging from 6 to 24 months compared to control mice that do not develop tumors some tumors show lymphocyte invasion
• tumors are invasive carcinomas that include solid tubular carcinomas, tubular carcinomas and carcinomas with sarcomatous changes
• tumors display ductal enlargement that may or may not be pre-existing
