  • Previously, we made a study report on the genotype distribution and the gene frequency of angiotesin I-converting enzyme (ACE) in Korean population, and on the association between hypertension and genetic variance of ACE. This time, we have investigated a rapid mismatch-PCR/RFLP assays for the variant of the angiotesin II type 1 receptor ($AT_1R$) gene (an $A{\rightarrow}C$ transversion at position 1166 of $AT_1R$ gene), a mutation which may interact with the ACE polymorphism in the determining of risk of myocardial infarction. The genotype distributions of Koreans' angiotensin II type 1 receptor gene were AA (66.3%):AC (28.1%):CC (5.6%), thus the AA genotype was most numerous, and the allele frequency was A:C = 0.803:0.197. Genotype distributions were shown as AA (76.8%):AC (20.9%):CC (2.3%), the allele frequency was A:C = 0.872:0.128 in the male group, and AA (47.4%):AC (41.0%):CC (11.6%), A:C = 0.679:0.321 in the female group. Differences were highly significant between the male and female groups (p<0.0001). Genotype distributions between angiotensin II type 1 receptor gene and angiotensin converting enzyme gene showed that there is no significance between $AT_1R$ genotypes and ACE genotypes in total subjects (p>0.05).

  • Objective : This study was designed to investigate the relation between the angiotensin converting enzyme(ACE) gene polymorphism and Facial nerve palsy in the Korean population. Methods : This sudy was carried out on 117 Facial nerve palsy patients who were treated in the department of acupuncture & moxibustion, Hospital of Oriental medical college, Kyung-Hee University and 135 healthy control subjects. Blood samples from all subjects were obtaind for DNA extraction. The extracted DNA was amplified by polymerase chain reaction(PCR). PCR products were visualized by 2% agarose gel electrophoresis. Results : The sub-genotypes of ACE gene were II homozygotes, ID heterozygotes, DD homozygotes. While the distribution of ACE polymorphism in control subjects was 33%, 43%, 24%, the distribution of it in Facial nerve palsy patients was 32%, 50%, 18%(II, ID, DD). Thus, there was no significant different between the control and Facial nerve palsy groups. Conclusions : we conclude that there is no significant association between ACE gene polymorphism and Facial nerve palsy in Korean population. However, the findings of this study need to be confirmed in more patients and further studies. Additional epidemiologically based studies of the effects and relationship between ACE or other genes and lifestyles with regard to Facial nerve palsy is required.

  • To assess the relationship between angiotensin-converting enzyme (ACE) gene polymorphism and myocardial infarction in Koreans, we recruited 112 healthy, unrelated subjects (mean age 53.4 years) and 104 myocardial infarction survivors (mean age 54.2 years) of both sexes. An insertion/deletion (I/D) polymorphism of the ACE gene was typed by polymerase chain reaction. The I allelic frequency of ACE gene in Korean subjects was irrelavant to myocardial infarction (patients, 65 control subjects 66%), as was true with the D allele. When compared with other populations, the frequency of D allele in Koreans (0.34) was lower than that in Caucasians, and was close to that of other Oriental populations. The data suggest that the ACE gene polymorphism is not an independent genetic risk factor for myocardial infarction in Koreans.

  • The angiotensin converting enzyme (ACE) is a key component of the renin-angiotensin system thought to be important in the pathogenesis of hypertension and cardiovascular diseases. Deletion polymorphism in the ACE gene may be a risk factor for myocardial infarction. The insertion/deletion (I/D) polymorphism of the ACE detected by PCR analysis appears to be associated with hypertension in Koreans and its nucleotide was subcloned into T-vector and its nucleotide sequences were determined. We also examined an association between hypertension and genetic variance of ACE. We identified the angiotensin I-converting enzyme genotype in 127 hypertensive and 189 normotensive Korean subjects. The distribution of ACE genotype II, ID, DD were 39.2%, 40.2%, 20.6% respectively and the frequency for ACE alleles I and D were 0.593 and 0.407, respectively in all subjects. The frequency of D allele in Korean males is higher than that of Korean females (male; 0.438 : female; 0.267), and the frequency of I allele in Korean females is higher than that of Korean males (female; 0.733 : male; 0.562). Genotype distributions of angiotensin I-converting enzyme genes in Korean normal adult population were different from that of Caucasians (P<0.001). There were no significant differences in genotype frequency between the hypertensive control group (n=127) and the normotensive group (n=189). We observed significant differences of ACE genotype distribution between the male group and the female group in total (P=0.001) and in hypertensive Korean subjects (P=0.013).

  • The genetic factors that contribute to the development of coronary artery disease (CAD) are poorly understood. It is likely that multiple genes that act independently or synergistically contribute to the development of CAD and the outcome. Recently, an insertion/deletion (I/D) polymorphism of the human angiotensin I-converting enzyme (ACE) gene, a major component of the renin-angiotensin system (RAS), was identified. The association of the ACE gene D allele with essential hypertension and CAD has been reported in the African-American, Chinese, and Japanese populations. However, other studies have failed to detect such an association. It has been suggested that these inconsistencies may be due to the difference in backgrounds of the population characteristics. In the present study, we investigated the I/D polymorphism of the ACE gene in 103 subjects of both sexes, consisting of 59 normal controls and 44 patients with hypertension. The allele and genotype frequency were significantly different between the hypertensive and control groups (p < 0.01). Among the three ACE I/D variants, the DD genotype was associated with the highest value of the mean systolic blood pressure [SBP] and mean diastolic blood pressure [DBP] (p = < 0.05) in men, but not in women. In the overall population, the mean SBP and DBP was highest in DD subjects, intermediate in I/D subjects, and the least in II subjects.

  • Recently it was reported that Insertion/Deletion polymorphism in the gene coding for Angiotensin-Converting Enzyme (ACE) is associated with human capacity for physical performance. This study was performed to genotyping of the ACE gene to determine the correlation between elite endurance performance and ACE I/D gene polymorphism. DNA sample was obtained from peripheral blood, hair roots and mouth epithelial cell in 739 general population and 200 elite athletic performance students. The ACE gene was amplified by polymerase chain reaction (PCR) using allele specific oligonucleotide primers. 155, 525 bp and 237 bp PCR products indicating the presence of insertion(I) and deletion(D) alleles, respectively, were clearly resolved after electrophoresis on a 2% agarose gel with ethidium bromide. Of the 200 elite athletic performance population subjects, 68(34%) showed ACE genotype 11,100(50%) genotype ID and 32(16%) genotype DD. Of the 739 general population subjects, 259(35.1%) showed ACE genotype 11,363(49.1%) genotype ID and 117(15.8%) genotype DD. Therefore ACE I/D gene polymorphism was not associated with human capacity for physical performance.(p>0.05)

  • Objective : This study was designed to investigate the relation between the angiotensin converting enzyme(ACE) gene polymorphism and stroke in the Korean population. Methods : This study was carried out on 58 stroke patients who were hospitalized in the department of acupuncture & moxibustion, college of Oriental Medicine, Kyung-Hee University and 61 healthy control subjects. Blood samples from all subjects were obtaind for DNA extration. The extracted DNA was amplified by polymerase chain reaction(PCR). PCR products were visualized by 2% agarose gel electrophoresis. Results : The sub-genotypes of ACE gene were II homozygotes, ID heterozygotes, DD homozygotes. While the distribution of ACE polymorphism in control subjects was 31%, 51%, 18%, the distribution of it in stoke patients was 33%, 52%, 16%(II, ID, DD). Thus, there was no significant different between the control and stroke groups. Conclusions : we conclude that there is no significant association between ACE gene polymorphism and storke in Korean papulation. However, the findings of this study need to be confirmed in large patients and further studies. Additional epidemiologicallly based studies of the effects and relationship between ACE or other genes and lifesyles with regard to stroke required.

  • The polymorphism (insertion, I or deletion, D) of angiotensin converting enzyme (ACE) gene is designated as the presence of a 287 bp Alu repeat. The D/D homozygote carrier is associated with high ACE activity, and this high activity has been implicated with hypertension, coronary artery disease, or diabetic nephropathy. We studied the clinical candidate marker in ACE gene polymorphism using chemical and hematological analysis. The subjects are divided into normotensive and hypertensive groups and ACE genotype in the group was confirmed by PCR method. Chemical analysis was preceded with Hitachi7060, and hematological analysis was performed using Mythic 22. In 116 targeted people, 17 (38.64%) of 44 I/I genotype group are hypertension, 15 (34.09%) in 44 with D/I, but, D/D type in the 28 cases is 15 patients (53.57%) in hypertension. In hypertension group, biochemical analysis (triglyceride, and alkaline phosphatase) and hematological analysis (white blood cell, platelet) are showed high value in D/D genotype of ACE gene. The relationship between hypertension and ACE genotype is the same results as previously reported and we thought that the high laboratory value of white blood cell, platelet, triglycerides, and alkaline phosphatase are also indicator of hypertension in D/D type of ACE.

  • The correlation between angiotensin converting enzyme (ACE) polymorphisms and cerebral infarction (CI) has been controversial. Such controversy may be due to different classifications of cerebrovascular diseases and ethnic differences. I studied the correlation between ACE genotypes and CI patients by case-control study in the Korean population. I also classified CI patients and control group into four types according to Sasang constitutional medicine. Furthermore I investigated the correlation among ACE genotypes, CI and Sasang constitutions. The frequencies of D allele were 0.32 in subjects with CI and 0.40 in the control group without CI (X2=0.128, p=0.720). In patients with CI, the frequency of Taeumins, one of four Sasang constitutional types, was significantly higher than that in controls (X2=15.425, p<0.00l). I did not find any correlation between ACE polymorphism and CI in Koreans. However, there were significant differences in allele frequencies between Koreans and Europeans, while similarities were shown to those of Japanese and Chinese populations.

  • Angiotensin converting enzyme (ACE) is a vital enzyme in the renin-angiotensin-aldosterone system, and there are literature reports describing its relationship between the ACE polymorphism and muscular strength, muscular endurance and flexibility. The purpose of this study is to identify the distribution of the ACE gene polymorphism among individual golfers and the relationship between different golfers group. We analyzed the ACE gene polymorphism to study the individual differences among professional golfers (n=35), junior golfers (n=30) and general golfers (n=25). Genotype frequencies of DD, ID and II in total golfers (n=90) were 16.7%, 52.2% and 31.1% respectively. In professional golfers, the frequencies of DD, ID and II were 25.7%, 45.7% and 28.6% respectively. The frequency of DD genotype in professional golfers was higher than in junior golfers and in general golfers, but the II genotype in professional golfers was lower than in other groups. In conclusion, these data suggest that the capability and power of golf exercise are associated with the hereditary characteristics of the ACE polymorphism.
