ABSTRACT
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.
RESUMO
Resumo Objetivo Examinamos a interação dos polimorfismos nos genes heme oxigenase-1 (HMOX1) eóxido nítrico sintase (NOS3) empacientes compré-eclâmpsia (PE)bem como as capacidades de resposta à metildopa e à terapia anti-hipertensiva. Métodos Os polimorfismos nos genes HMOX1 (rs2071746, A/T) e NOS3 (rs1799983, G/T) foram genotipados usando TaqMan allele discrimination assays (Applied Biosystems, Foster City, CA, EUA), e os níveis da enzima heme oxigenase-1 (HO-1) foram medidos por enzyme-linked immunosorbent assay (ELISA). Resultados Foram encontradas interações entre os genótipos da HMOX-1 e NOS3 e responsividade à metildopa, e que pacientes genotipados como AT apresentam níveis mais baixos de proteína HO-1 em comparação com o genótipo AA. Conclusão Foram encontradas interações entre os genes HMOX-1 e NOS3 e responsividade à metildopa e que o polimorfismo localizado no gene HMOX1 afeta os níveis de enzima HO-1 na resposta à metildopa e à terapia anti-hipertensiva. Esses dados sugerem o impacto da combinação desses dois polimorfismos na resposta antihipertensiva na PE.
