BACKGROUND Angiotensinogen, a key protein in the renin-angiotensin system, plays an important role in cardiovascular hemostasis. Many studies have examined the association between polymorphisms in the angiotensinogen gene and risk of coronary heart disease (CHD), but the results have been inconsistent. METHODS AND RESULTS We performed a meta-analysis of 43 associations studies on 2 angiotensi...

Transgenic mice were generated by injecting the entire rat angiotensinogen gene into the germline of NMRI mice. The resulting transgenic animals were characterized with respect to hemodynamics, parameters of the renin angiotension system, and expression of the transgene. The transgenic line TGM(rAOGEN)123 developed hypertension with a mean arterial blood pressure of 158 mmHg in males and 132 mm...

The M235T mutation of the human angiotensinogen gene has been shown to be associated with elevated circulating angiotensinogen concentrations and essential hypertension. The frequencies of the 235T allele are significantly different in black and white subjects. We analyzed the independent contribution of the angiotensinogen M235T mutation to the development of recurrent coronary events (coronar...

Previous researchers have identified two sequences present upstream (angiotensinogen gene–activating element [AGE2]) and downstream (d61–2) of the human angiotensinogen gene that act as cell-specific enhancers of transcription in transiently transfected HepG2 cells. To examine the importance of these two sequences in regulating tissueand cell-specific expression of the gene in vivo, we generate...

We tested the hypotheses that angiotensin-converting enzyme insertion/deletion (I/D) and angiotensinogen 235 methionine/threonine (M/T) substitution gene polymorphisms influence angiotensin-converting enzyme and angiotensiongen serum concentrations and cardiac dimensions in 91 monozygotic and 41 dizygotic twin pairs. Cardiac dimensions were determined echocardiographically. Angiotensin-converti...

A a Abstract. Objective: to develop a rapid and reliable real-time PCR to detect polymorphisms of angiotensinogen (AGT), to compare the two methods of MSPCR (Mutagenically Separated PCR) and real-time PCR to determine three polymorphisms of the angiotensinogen gene M235T, the A (-6) G and A (-20) C. Methods: the method of real-time PCR was developed on the PLC Roche LightCycler1 with SYBR Green...
