Induction of aryl hydrocarbon hydroxylase activity and pulmonary carcinoma.
Aryl hydrocarbon hydroxylase activity in lymphoblasts from normal Finnish adults and from patients with pulmonary carcinomas and other types of malignancy has been studied by a modification of previously used techniques. High absolute induced aryl hydrocarbon hydroxylase activity was found in 39% of patients with untreated lung cancer but only in 15% of normal people. No increased frequency was found in the control group comprising other malignancies. The diagnosis of pulmonary carcinoma was made at a lower mean age (4.9 years younger) in the individuals with high aryl hydrocarbon hydroxylase activity than in those with low activity. High absolute aryl hydrocarbon hydroxylase activity was dominantly inherited in normal individuals, and the frequency of athe Ahb gene in the Finnish population was 8%.
