Established from an adenocarcinoma from a 44-year-old female. Tumorigenic in nude mice and has ability to grow in agar. They have human adrenergic alpha2A urokinase receptor (u-PAR), vitamin D (moderate expression) and urokinase receptor (u-PAR); The cell line can produce secretory component of IgA, carcinoembryonic antigen (CEA), transforming growth factor beta binding protein and mucin. Ultrastructural features include microvilli, microfilaments, large vacuolated mitochondria with dark granules, smooth and rough ER with free ribosomes, lipid droplets, few primary and many secondary lysosomes. There is a G -> A mutation in codon 273 of the p53 gene resulting in an Arg -> His substitution.
