NCI-H358

Test system for evaluating cytotoxicity and genotoxicity of chemicals to human lung

Human Caucasian bronchioalveolar carcinoma

NCI-H358 was isolated from a primary bronchioalveolar carcinoma of the lung from a Caucasian male taken prior to treatment. Ultrastructural studies of this non-small cell carcinoma of the lung (NSCLC) demonstrated the presence of granules characteristic of Clara cells. NCI-H358 do not express UDP-glucuronosyltransferases, but do express glutathione-S-transferase and phenol sulphotransferase. Expression of SP-A protein and RNA, the major surfactant-associated protein was detected. SP-B and SP-C RNA was not expressed. A complete homozygous deletion of the p53 gene and therefore a lack of p53 protein has been reported. A colony forming efficiency of 0.83% in soft agarose, and growth in serum-free media has been reported. The cells are tumourigenic in athymic nude mice, and exhibit a doubling time of 38 hours in RPMI 1640 medium. Since these cells are proficient in oxidation of xenobiotics but deficient in their conjugation with glucuronic acid they present a tool for analysing the role of glucuronic acid conjugation in the inactivation of chemicals in intact cells.
