mortality/aging
premature death ( J:140423 )
• median survival of mice infected with RCASBP(A)-shTP53, which knocks down Trp53 expression, is only 151 days compared to 485 days for controls

neoplasm
increased pancreatic ductal adenocarcinoma incidence ( J:140423 )
• mice infected with RCASBP(A)-shTP53, which knocks down Trp53 expression, display a significantly shorter latency of pancreatic ductal adenocarcinoma development
• all infected mice develop invasive pancreatic ductal adenocarcinoma within 10 months

endocrine/exocrine glands
increased pancreatic ductal adenocarcinoma incidence ( J:140423 )
• mice infected with RCASBP(A)-shTP53, which knocks down Trp53 expression, display a significantly shorter latency of pancreatic ductal adenocarcinoma development
• all infected mice develop invasive pancreatic ductal adenocarcinoma within 10 months

neoplasm
increased pancreatic ductal adenocarcinoma incidence ( J:140423 )

• all pancreatic ductal adenocarcinomas display a ductal phenotype, an intense desmoplastic stroma and local infiltration
increased pancreatic intraepithelial neoplasia incidence ( J:140423 )
• 9 months after infection with RCASBP(A)-KrasG12D retrovirus 4 of 5 mice developed focal ductal pancreatic lesions that closely resembled human pancreatic intraepithelial neoplasias
