This study analyzed gene expression in the endocervical epithelium of women with and without deep endometriosis, finding eight genes (five cell cycle related and three inflammatory) that were underexpressed in women with endometriosis.

This study assessed differences in gene expression in the endocervical epithelium of women with deep endometriosis versus healthy controls, with the goal of identifying potential targets for a non-invasive diagnostic test. Using RT-PCR, the authors analyzed samples from 4 women with deep endometriosis and 6 healthy women and found that eight genes were hyperexpressed in the endometriosis group, including five related to cell-cycle control (CCNB1, CCNG1, CUL1, GTF2H1, PCNA) and three inflammatory cytokines (C3, CCL21, CXCL14). The paper explicitly frames this as a promising screening approach but is limited by its very small sample size. This paper is centrally about endometriosis — it investigates gene-expression differences in endocervical epithelium in women with deep endometriosis as potential basis for a non-invasive diagnostic test.

Abstract

A falta de marcadores diagnósticos da endometriose faz com que a cirurgia seja realizada com este objetivo. Trata-se de um método invasivo de alto custo colaborando para o cenário mundial, em que observa-se em média sete anos para que a doença seja diagnosticada desde os primeiros sintomas. Objetivo: Este estudo tem como base as alterações de expressão gênica no endométrio de mulheres com endometriose. Visto que o corpo e colo uterino possuem origem embrionária comum e receptores para estrogênio e progesterona já fórum descritos na cérvix, este estudo visa identificar se há diferenças na expressão gênica no epitélio endocervical com a perspectiva de criação de um teste não invasivo para o diagnóstico da doença. Métodos: Realizamos análise com RT-PCR do epitélio endocervical de 4 mulheres com endometriose profunda e 6 mulheres saudáveis. Resultados: Oito genes apresentaram hiperexpressão em amostras de mulheres com endometriose, cinco genes dos genes relacionados ao controle do ciclo celular (CCNB1, CCNG1, CUL1, GTF2H1, PCNA) e três genes a citocinas inflamatórias (C3, CCL21 e CXCL14). Conclusão: Análise da expressão gênica no epitélio endocervical de mulheres com endometriose é uma promissora ferramenta de rastreio não invasivo no diagnóstico de endometriose.

Análise da expressão gênica no epitélio endocervical de mulheres com endometriose profunda Data Tipo Título da Revista ISSN da Revista Título de Volume Resumo A falta de marcadores diagnósticos da endometriose faz com que a cirurgia seja realizada com este objetivo. Trata-se de um método invasivo de alto custo colaborando para o cenário mundial, em que observa-se em média sete anos para que a doença seja diagnosticada desde os primeiros sintomas. Objetivo: Este estudo tem como base as alterações de expressão gênica no endométrio de mulheres com endometriose.

Métodos: Realizamos análise com RT-PCR do epitélio endocervical de 4 mulheres com endometriose profunda e 6 mulheres saudáveis. Resultados: Oito genes apresentaram hiperexpressão em amostras de mulheres com endometriose, cinco genes dos genes relacionados ao controle do ciclo celular (CCNB1, CCNG1, CUL1, GTF2H1, PCNA) e três genes a citocinas inflamatórias (C3, CCL21 e CXCL14). Conclusão: Análise da expressão gênica no epitélio endocervical de mulheres com endometriose é uma promissora ferramenta de rastreio não invasivo no diagnóstico de endometriose. The lack of diagnostic markers of endometriosis causes the surgery to be performed for this purpose. It is an invasive method of high cost contributing to the global scenario, where there has been an average of seven years before the disease is diagnosed from the first symptoms. Objective: This study is based on the changes of gene expression in the endometrium of women with endometriosis. Since the body and cervix have common embryonic origin and receptors for estrogen and progesterone have forum described in the cervix, this study aims to identify whether there are differences in gene expression in endocervical epithelium with the prospect of creating a non-invasive test for the diagnosis of disease. Methods: We performed RT-PCR analysis of the endocervical epithelium of 4 women with deep endometriosis and 6 healthy women. RESULTS: Eight genes showed overexpression in samples of women with endometriosis, five genes of genes related to cell cycle control (CCNB1, CCNG1, CUL1, GTF2H1, PCNA) and three genes inflammatory cytokines (C3, CCL21 and CXCL14).
