Thymosin beta-4 A/T polymorphism and acute coronary syndrome risk

Aim: Acute coronary syndrome (ACS) describes all the clinical conditions due to myocardial infarction that is caused by decreased blood flow in the coronary artery. Thymosin beta-4 (Tβ4) plays a significant role in the recovery of damaged tissues and promoting the survival of cardiomyocytes in ACS. In this study, it was aimed to determine the Tβ4 A/T (rs75112573) variation in ACS and its effects on the disease. Methods: This was a prospective case-control study. Forty-eight patients with ACS and 45 healthy controls were recruited for this study. Genetic analysis was performed using polymerase chain reaction/restriction fragment length polymorphism (PCR/RFLP). Results: The AT genotype (p

Timozin beta-4 A/T polimorfizmi ve akut koroner sendrom riski

Amaç: Akut koroner sendrom (ACS), koroner arter kan akımının azalması sonucu miyokard iskemisinin neden olduğu klinik tabloların tamamını ifade eder. Thymosin beta-4 geni (Tβ4) hasarlı dokuların iyileşmesinde ve ACS’de kardiyomiyositlerin canlı kalmasında önemli rol oynamaktadır. Bu çalışmada ACS’li hastaların Tβ4 genindeki A/T (rs75112573) varyasyonunun tespit edilmesi ve akut koroner hastalığına olan etkilerinin belirlenmesi amaçlanmıştır. Yöntemler: Bu prospektif bir vaka kontrol çalışmasıdır. Çalışmaya ACS'li 48 hasta ve 45 sağlıklı kontrol birey dahil edildi. Genetik analiz, polimeraz zincir reaksiyonu/restriksiyon parça uzunluk polimorfizmi (PCR / RFLP) yöntemleri kullanılarak yapıldı. Bulgular: Kontrol grubu ile karşılaştırıldığında hasta grubunda AT genotipi (p
