Expressão do gene da aromatase (CYP19A1) nas células da granulosa murais luteinizadas de mulheres com endometriose submetidas a técnicas de reprodução assistida
Real-time PCR analysis showed no difference in aromatase (CYP19A1) gene expression in mural luteinized granulosa cells from women with endometriosis compared to controls undergoing assisted reproduction.

Este estudo caso-controle investigou se a expressão do gene da aromatase (CYP19A1) difere entre mulheres com endometriose e controles sem endometriose, medindo por PCR em tempo real o RNAm em células da granulosa mural luteinizadas obtidas de folículos pré-ovulatórios durante a hiperestimulação ovariana controlada para reprodução assistida. Foram incluídas 11 mulheres com endometriose e 11 com infertilidade por fatores tubáreo ou masculino, totalizando 12 ciclos no grupo com endometriose e 11 no controle, com RNA extraído e normalizado por ß-actina, e todos os experimentos em duplicata. Não houve diferença significativa na expressão de CYP19A1 entre os grupos, nem quando os casos foram estratificados por grau de endometriose. A conclusão do trabalho aponta que, apesar de evidências prévias de redução de atividade da aromatase em células da granulosa na endometriose, neste contexto a expressão do gene não parece estar alterada. This paper is centrally about endometriosis — it measures CYP19A1/aromatase gene expression in luteinized mural granulosa cells from women with endometriosis undergoing assisted reproduction.
