The p53 genotype of all the pancreatic carcinoma was either mutated (PANC-1, BxPC-3 and MIA-PaCa-2) or deleted (AsPC-1), and that of all the mesothelioma was wild-type except NCI-H2452 cells which had truncated p53 protein despite the wild-type p53 gene. The gene discussed is TP53; the disease is exocrine pancreatic carcinoma.
