Interaction Between NOS3 and HMOX1 on Antihypertensive Drug Responsiveness in Preeclampsia

Interaction Between NOS3 and HMOX1 on Antihypertensive Drug Responsiveness in Preeclampsia

Abstract Objective We examined the interaction of polymorphisms in the genes heme oxygenase- 1 (HMOX1) and nitric oxide synthase (NOS3) in patients with preeclampsia (PE) as well as the responsiveness to methyldopa and to total antihypertensive therapy. Methods The genes HMOX1 (rs2071746, A/T) and NOS3 (rs1799983, G/T) were genotyped using TaqMan allele discrimination assays (Applied Biosystems, Foster City, CA, USA ), and the levels of enzyme heme oxygenase-1 (HO-1) were measured using enzyme-linked immunosorbent assay (ELISA). Results We found interactions between genotypes of the HMOX-1 and NOS3 genes and responsiveness tomethyldopa and that PE genotyped as AT presents lower levels of protein HO-1 compared with AA. Conclusion We found interactions between the HMOX-1 and NOS3 genes and responsiveness to methyldopa and that the HMOX1 polymorphism affects the levels of enzyme HO-1 in responsiveness to methyldopa and to total antihypertensive therapy. These data suggest impact of the combination of these two polymorphisms on antihypertensive responsiveness in PE.
