OBJECTIVE Tyrosine hydroxylase (TH) is the rate-limiting enzyme in dopamine biosynthesis. Because the TH Val81Met polymorphism is located in the amino-terminal regulatory domain of the tetrameric enzyme, it is a candidate marker for susceptibility to dopamine-related traits. We investigated the hypothesis that TH Val81Met polymorphism can influence susceptibility to tardive dyskinesia (TD) in s...
Background: Angiotensin I converting enzyme (ACE) is a Zinc metalloproteinase, converts Ang-I to Ang- II, a pro-inflammatory agent which may contribute to pathophysiology of some diseases like type 2 diabetes. Objective: To investigate the relationship between ACE I/D polymorphism and type 2 diabetes in 261 Iranian casecontrol pairs. Methods: 170 patients (85 type 2 diabetics with nephropathy a...
Detection of low frequency mutations following exposure to mutagens or during the early stages of cancer development is instrumental for risk assessment and molecular diagnosis. We present a sensitive new method to detect trace levels of DNA mutations induced within a large excess of wild-type sequences. The method is based on mutation-induced generation of new restriction enzyme recognition si...
