Oksidatif stres durumunda antioksidan enzimlerin rolü - Süperoksit dismutaz (SOD), katalaz (CAT) ve glutatyon peroksidaz (GPX)
Öz
Vücut enzimatik ve enzimatik olmayan karmaşık bir antioksidan savunma sistemine sahiptir. Antioksidan mekanizmalar vücut dokuları için zararlı etkilere sahip olan serbest radikallere karşı savunma sistemi geliştirirler. Süperoksit dismutaz (SOD), katalaz (CAT) ve glutatyon peroksidaz (GPX) hücrede serbest radikallere karşı temel savunma hattını oluştururlar. Serbest radikaller özellikle mitokondriyal enerji üretim yoluyla sürekli olarak üretilir.
Serbest radikallerin hücrede birikmesi oksidatif strese ve hücresel hasara neden olur. Hücre reaktif oksijen türlerinde artışın nörodejeneratif, kardiyovasküler, diyebet ve böbrek hastalıkları gibi bir çok hastalıkların patogenezinde rol oynadığı ifade edilmektedir. SOD, CAT ve GPx’in hücresel hasarı önlemedeki rolü sürekli olarak araştırılmaktadır.
Bu derleme makalesi, SOD, CAT ve GPX antioksidan enzimlerinin oksidatif stresi önlemedeki rolünü açıklamak için yazılmıştır.
