Abstract
Cilj istraživanja: Cilj diplomskog rada je odrediti učinak nadomjestka karnozina na izražaj gena antioksidativnih enzima u uzorcima aorte Sprague-Dawley štakora izloženih standardnoj i visokoslanoj prehrani. Nacrt studije: Eksperimentalna studija na pohranjenim aortama Sprague-Dawley štakora. Materijal i metode: Zdravi Sprague-Dawley štakori oba spola (starosti 8-10 tjedana) nasumično su podijeljeni u četiri skupine: kontrolna skupina (CTRL, standarna prehrana s 0,4 % NaCl), skupina na visokoslanoj prehrani (HSD, 4 % NaCl), skupina koja je konzumirala karnozin (CTRL + CAR, 150 mg/kg) te skupina na visokoslanoj prehrani koja je konzumirala karnozin (HSD + CAR). Nakon jednotjednog protokola, štakori su anestezirani i izolirani su uzorci aorte. Nakon ekstrakcije RNA, određen je relativni izražaj SOD2, SOD3, GPx1, GPx4 i CAT uz korištenje βaktina kao housekeeping gena. Rezultati: Razina genskog izražaja SOD2, GPx1, i GPx4 povišena je u HSD + CAR skupini. Izražaj SOD2 također je povišen u CTRL + CAR skupini. Nije uočena značajna promjena izražaja SOD3 i CAT. Buduća istraživanja mogu se usmjeriti na određivanje izražaja proteina te aktivnosti enzima kako bi se dodatno razjasnila uloga karnozina. Zaključak: Primjena karnozina dovela je do povećanog izražaja gena antioksidativnih enzima tijekom visokoslane prehrane.
Abstract (english)
Objectives: The study aimed to determine the impact of carnosine supplementation on relative expression of antioxidant enzyme genes in samples of rat aortas during a normal diet and a highsalt diet. Study design: Experimental animal study using isolated blood vessels of Sprague-Dawley rats. Material and methods: Healthy, male and female Sprague-Dawley rats (aged 8 - 10 weeks) were randomly divided into four groups: the control group (CTRL, standard 0,4 % NaCl diet), high-salt diet group (HSD, 4 % NaCl), group that was administered carnosine (CTRL + CAR, 150 mg/kg oral carnosine) and the high-salt diet group that was simultaneously given carnosine (HSD + CAR). After the one week long protocol, the rats were anesthetized, and samples of the aorta were taken. After RNA extraction, relative gene expressions of SOD2, SOD3, GPx1, GPx4 and CAT were measured using RTqPCR, with β-actin as the housekeeping gene. Results: In the HSD + CAR group, levels of SOD2, GPx1 and GPx4 expression were increased. SOD2 was also elevated in the carnosine supplemented group that was fed a normal diet. No notable change was recorded in SOD3 and CAT expression. Future research can be directed towards determining protein expression and enzyme activity to further clarify the role of carnosine. Conclusion: Administration of carnosine led to an increase in relative expression of antioxidant enzyme genes during a high-salt diet.
