Insights
This study investigated the angiotensin-converting enzyme gene
Area of Science:
- Genetics
- Neurology
- Cardiovascular Research
Background:
- The angiotensin-converting enzyme (ACE) gene is implicated as a potential stroke risk factor.
- Middle cerebral artery stenosis (MCAS) is a significant cause of ischemic stroke.
Purpose of the Study:
- To investigate the association between ACE gene polymorphisms (DD genotype and D allele) and MCAS in a Han Chinese population.
- To explore the role of ACE as a genetic marker for stroke risk in MCAS patients.
Main Methods:
- Genotyping of the ACE gene was performed using PCR-restriction fragment length polymorphism (PCR-RFLP) analysis.
- Peripheral blood samples were collected from 148 MCAS patients and 62 healthy controls.
- Frequencies of ACE genotypes and alleles were compared between patient and control groups.
Main Results:
- The frequencies of the ACE DD genotype and D allele were numerically higher in MCAS patients compared to healthy controls.
- However, these observed differences in genotype and allele frequencies did not reach statistical significance.
- No significant correlation was found between ACE gene variants and MCAS in this North China Han population.
Conclusions:
- The ACE gene DD genotype and D allele are not significantly associated with middle cerebral artery stenosis in the studied Han population.
- Further research is warranted to explore the synergistic effects of multiple stroke candidate genes on MCAS.
- This study provides a foundation for future investigations into gene therapy for stroke prevention and treatment.
Abstract:
The angiotensin-converting enzyme gene is a candidate gene of stroke. The present study involved 62 healthy volunteers and 148 patients with middle cerebral artery stenosis as confirmed by brain color ultrasound from a Han population in North China, and determined the peripheral blood angiotensin-converting enzyme genotype using PCR-restriction fragment length polymorphism analysis. The results showed that the frequencies of the DD genotype and D allele were increased in patients with middle cerebral artery stenosis, but the difference was not statistically significant compared with healthy controls. The findings of this study on the relationship between stroke genes and middle cerebral artery stenosis indicate no significant correlation between the frequencies of the DD genotype and D allele of angiotensin-converting enzyme and middle cerebral artery stenosis in this Han population from North China. In the future, studies will be carried out to investigate correlations between multiple stroke candidate gene synergy and middle cerebral artery stenosis to provide a foundation for the development of gene therapy.
