Abstract
Cilj: Utvrditi izražajnost proteina enzima ciklooksigenaze 1 i ciklooksigenaze 2 u krvnim žilama štakora koji su tjedan dana pili vodu s losartanom (blokatorom angiotenzin II AT-1 receptora) na modelu zdravih Sprague-Dawley štakora pomoću molekularne metode Western blot. Materijali i metode: Zdravi muški Sprague-Dawley (SD) štakori u dobi 9 - 11 tjedana starosti. Jedna je skupina štakora pila običnu vodu (CTRL skupina, kontrolna), a druga je skupina štakora kroz vodu za piće primala 40 mg losartana (ukupna dnevna doza) kroz sedam dana (CTRL+LOSARTAN skupina). U uzorcima krvnih žila mozga Western blot metodom, određen je izražaj proteina ciklooksigenaze 1 (COX-1) i ciklooksigenaze 2 (COX-2). Rezultati: Izražaj COX-2 statistički je značajno povećan u CTRL+LOSARTAN skupini u usporedbi s CTRL skupinom. Razlika izražaja COX-1 u CTRL-LOSARTAN skupini u odnosu na CTRL skupinu nije statistički značajna. Zaključak: Primjena blokatora angiotenzin II AT-1 receptora (losartana) tijekom sedam dana uzrokuje značajnije povećanje u izražaju enzima ciklooksigenaza 2 (COX-2) u moždanim krvnim žilama Sprague-Dawley štakora. U izražaju enzima ciklooksigenaza 1 (COX-1), za razliku od COX-2, nema značajnije promjene.
Abstract (english)
Aim: To determine the expression of the enzyme cyclooxygenase 1 and cyclooxygenase 2 protein in the blood vessels of the rats that were weekly drinking water with losartan (angiotensin II receptor AT-1 blocker) on a model of healthy Sprague-Dawley rats using a Western blot molecular method. Materials and Methods: Healthy male Sprague-Dawley (SD) rats were 9-11 weeks old. One group of rats was drinking common water (CTRL group, control), and the other group of rats received 40 mg of losartan (total daily dose) through water for seven days (CTRL + LOSARTAN group). The expression of cyclooxygenase 1 (COX-1) and cyclooxygenase 2 (COX-2) proteins in brain blood vessel samples was determined by the usage of the Western blot method. Results: Expression of COX-2 was statistically significantly increased in the CTRL + LOSARTAN group compared to the CTRL group. And the difference in expression of COX-1 in the CTRL-LOSARTAN group compared to the CTRL group is not statistically significant. Conclusion: Inatake of angiotensin II AT-1 receptor blocker (losartan) in organism for seven days causes a significant increase in the expression of cyclooxygenase 2 (COX-2) enzyme in the brain blood vessels of Sprague-Dawley rats. There are no significant changes in expression of enzyme cyclooxygenase 1 (COX-1).
