Sažetak
Uvod: Epoksi-ekosatrienoične kiseline (EET) imaju antihipertenzivna, protivupalna i zaštitna svojstva organa i nivoi njihove cirkulacije povezani su sa hipertenzijom, dijabetesom, kardiovaskularnim bolestima i preeklampsijom. Rastvoriva epoksidna hidrolaza (sEH) katalizuje razgradnju EET-a na biološki manje aktivne dihidroksiekosatrienoične kiseline. Uradili smo analizu sekvenci regiona promotera EPHKS2 da bismo istražili povezanost izmena sekvenci promotera za koje smo mislili da utiču na nivoe ekspresije enzima i preeklampsije (PE). Metode: Nukleotidno sekvenciranje promoterske regije EPHKS2, koje se proteže od položaja -671 do +30 izvršeno je na 100 trudnica sa PE, kao i na ženama koje su bile trudne 20 ili više nedelja, a koje su bile zdrave i sa normalnim krvnim pritiskom (n = 100). Rezultati: Trudnice koje nose rs4149235, rs4149232, rs73227309 i rs62504268 polimorfizme imaju 4,4, 2,4, 2,3 i 2,8 puta značajno povećan rizik od PE. CCGG (OR: 3,11; 95% CI: 1,12-8,62) i CCCA (OR: 0,45; 95% CI: 0,36-0,55) haplotipovi su povezani sa povećanim i smanjenim rizikom od PE. Zaključak: četiri SNP-a (rs4149232, rs4149235, rs73227309 i rs62504268) u promoterskoj regiji EPHKS2, i CCGG i CCCA haplotipovi ova 4 SNP-a su u značajnoj vezi sa PE. Ovi SNP-ovi u promoterskoj regiji mogu uticati na ekspresiju sEH, a time i na aktivnosti enzima i mogu igrati ulogu u patogenezi PE uzrokujući pojedinačne razlike u nivoima EET-a. Međutim, potrebno je sprovesti dodatne studije u budućnosti da se potvrde naša otkrića i da se ispita uticaj ovih SNP-a na sEH ekspresiju i/ili aktivnost enzima.
