Abstract
CILJ: Cilj istraživanja bio je utvrditi spolno uvjetovane razlike u izražaju gena antioksidacijskih enzima u tkivu aorti preddijabetičkih Sprague-Dawley štakora koji su konzumirali hranu bogatu mastima i šećerima. MATERIJALI I METODE: Zdravi Sprague-Dawley štakori, oba spola, starosti 10 mjeseci podijeljeni su u četiri skupine: kontrolna skupina, HSHFD skupina, HSHFD + metformin skupina i HSHFD + liraglutid skupina te su uvedeni dijetni protokoli u trajanju od 4 mjeseca. Iz tkiva aorte izmjeren je izražaj gena antioksidacijskih enzima (Cu/Zn SOD, MnSOD, EC-SOD, GPx1, 4 i katalaze) pcr metodom u stvarnom vremenu. REZULTATI: Terapija liraglutidom izazvala je gubitak tjelesne mase kod obaju spolova, ali značajno kod ženskih štakorica. Izražaj EC-SOD, GPx1 i katalaze povećan je u aortama štakorica skupine HSHFD + liraglutid u usporedbi s ostalim ispitivanim skupinama. U HSHFD + liraglutid skupini štakorica izražaj gena CuZnSOD značajno je povećan u usporedbi s HSHFD i HSHFD + metformin skupinom. Izražaj GPx4 smanjen je u skupini HSHFD + metformina u usporedbi s ostalim skupinama ženskih aorti. Izražaj MnSOD-a nije se značajno promijenio među skupinama ženskog spola. U muškoj skupini štakora izražaj se antioksidacijskih enzima nakon HSHFD prehrane nije značajno promijenio. ZAKLJUČAK: Hrana s visokim udjelom masnoće dovodi do pojave pretilosti kod obaju spolova. Promjene antioksidacijskih enzima značajnije su kod ženskog spola. Terapija je liraglutidom značajno povećala antioksidacijski status kod ženskog spola. Također, metformin nije značajno utjecao na promjene antioksidacijskogs statusa u ispitivanim skupinama.
Abstract (english)
AIM: The aim of the study was to determine the sex differences in the expression of antioxidative enzymes in aortas of prediabetic Sprague-Dawley rats which consumed fat and sugar rich food. MATERIALS AND METHODS: Healthy Sprague-Dawley rats, both sexes, aged 10 months were divided into four groups: control group, HSHFD group, HSHFD + metformin group and HSHFD + liraglutide group. They were included in 4 month diet protocols. From aortic tissue was measured gene expression of antioxidative enzymes (Cu/Zn SOD, MnSOD, EC-SOD, GPxl, 4 and catalase) by PCR in real time. RESULTS: Liraglutide therapy caused loss of body weight in both sexes, but significant in female rats. The expression of EC-SOD, GPx1 and catalase was increased in aorta of HSHFD + liraglutide rats compared to other investigated groups. In the HSHFD + liraglutide group, Cu/ZnSOD was significantly increased comapred to HSHFD and HSHFD + metformin groups. Expression of GPx4 was decreased in the HSHFD + metformin group compared to other female groups. Expression of MnSOD did not change significantly between groups. In male group of rats expression of antioxidative enzymes after HSHFD diet was decreases, and was not affected by antidiabetic treatment. CONCLUSION: Foods with high fat content leads to obesity in both sexes and increased oxidative stress. Expression of antioxidative enzymes are more significant in female experimental group. Liraglutide therapy has significantly increased antioxidative status in femals. Also, metformin did not significantly affect on the reduction of antioxidative stress caused by obesity.
