Cytochrome P4501IEI is responsible for the activation of carcinogenic N-nitrosamines, benzene, urethane, and other low-molecularweight compounds. Restriction fragment length polymorphisms (Pstl and RsaI restriction enzymes) have been identified in the cytochrome P4501IE1 transcription regulatory region that may affect expression. This study describes the PstI and RsaI polymorphisms in different...

Because renin is an important enzyme in blood pressure regulation, we studied the possibility that an alteration in the structure of the human renin gene is genetically linked to human essential hypertension or associated with levels of plasma renin activity or blood pressure. By using specific DNA probes, we have identified four polymorphisms in the human renin gene with the restriction enzyme...

One-hundred eight Mycobacterium avium isolates from pigs, humans, birds, and bovines were typed by the IS1245-based restriction fragment length polymorphism (RFLP) method and PCR-restriction enzyme analysis (PRA) of hsp65. Nine clusters of isolates showing more than 80% similarity in their RFLP profiles were detected. The largest cluster (cluster B) included 32 of 79 pig isolates (40.5%), 3 of ...
