mortality/aging
• mice die within 2 days of birth

endocrine/exocrine glands
• the spaces between the remaining ductal epithelia are filled with stromal tissue, including fibroblasts and smooth musce cells
• very few beta cells are present between E17.5 and P1
• at E13.5, pancreatic precursor cells fail to expand resulting in fewer than normal glucagon+ and amylase+ cells
• pancreatic development is arrested at the early pancreatic cord stage
• the pancreas occupies 19% relative area compared to in wild-type mice
• the numbers of endocrine cells, exocrine cells, and total epithelial tissue is severely decreased compared to in wild-type mice with remaining cells exhibiting an almost exclusively ductal phenotype

neoplasm
• male mutants injected with DEN followed by TCPOBOP (carcinogen treatment) show reduced tumor growth compared to control males that develop severe hepatocellular carcinoma
• female mutants injected with DEN followed by TCPOBOP (carcinogen treatment) to induce rapid hepatocellular carcinoma formation, develop multiple and large liver tumors unlike control females that are resistant to hepatocellular carcinoma development
• in females treated with fulverstrant to block estrogen signaling, DEN-induced liver injury is significantly attenuated
• estrogen treatment of male mutants enhances liver injury in DEN-treated males while in DEN-treated controls estrogen treatment prevents liver injury and carcinogenesis
• female mutants injected with N,N-diethylnitrosamine (DEN) followed by TCPOBOP two-step strategy (carcinogen treatment) to induce rapid hepatocellular carcinoma formation, develop multiple and large liver tumors unlike control females that are resistant to hepatocellular carcinoma development
• male mutants injected with DEN followed by TCPOBOP show reduced tumor growth compared to control males that develop severe hepatocellular carcinoma
