This study investigated the expression of genes associated with cellular motility in primary endometrial cells obtained from women diagnosed with deep infiltrating endometriosis compared to a control group undergoing tubal ligation. Using RT-PCR analysis, the researchers found that CAV1 was downregulated while RHOB and PLD1 were upregulated in the endometriosis group, indicating altered pathways involved in cell migration and progression. The authors note that these molecular changes suggest a potential role for these specific genes in the establishment and advancement of endometriotic implants. This paper is centrally about endometriosis — specifically examining the genetic mechanisms of cellular motility in deep infiltrating lesions.

Abstract

Endometriosis is a common, benign, estrogen-dependent inflammatory disease and is a chronic gynecological disorder. The pathology affects approximately 10% of women in reproductive age and 35-50% of women who presents pelvic pain and infertility. The histological origin of endometriosis aims to explain the ability of endometrial tissue to develop ectopically. However, no consensus has been reached with regard to a single theory is able to explaining such capability. The retrograde menstruation is the oldest and accepted theory, but it does not explain how some women develop endometriosis and others do not, since all women have some degree of retrograde flow. Cell migration plays a central role in a wide variety of biological phenomena and contributes to the progression of most human diseases. In the adult organism the migration remains remarkable being essential for adequate immune response, wound repair and tissue homeostasis, nonetheless, in several pathologies it appears abnormally. However, little is known on the role of cellular motility mechanisms for the establishment and progression of endometriosis implants. The aim of this study was to evaluate, using RT-PCR, the expression of genes related to the cellular motility processes in primary cells derived from the endometrium of women with deep infiltrating endometriosis and women without the disease. For this, endometrial samples were obtained from volunteers of Pain Unit Pelvic and Endometriosis Department of Gynecology, Paulista Medical School of the Federal University of São Paulo (EPM-UNIFESP). Women between 29 and 35 years were recruited. For endometriosis group, women undergoing for surgery of IV stage endometriosis and the control group were composed of women submitted to laparoscopy for tubal ligation. The samples were cultured and stored for the RT-PCR realization in order to analyze the possible genes involved in the cellular motility process in primary cells derived from the endometrium of women with deep endometriosis. It was possible to observe that endometrial cells from women with deep endometriosis showed the gene CAV1 downregulated, a gene related to a tumor suppression; RHOB and PLD1 were upregulated, which are involved in cell migration and progression. In this sense, it is suggested that these genes may play an important role in the establishment and progression of endometriosis.

A endometriose é uma doença inflamatória comum, benigna, dependente de estrogênio e trata-se de um transtorno ginecológico crônico. Atinge aproximadamente 10% das mulheres em idade reprodutiva e 35% a 50% destas mulheres apresentam dor pélvica e infertilidade. A origem da endometriose tem intima ligação com a capacidade do tecido endometrial de se desenvolver ectopicamente. No entanto, não há consenso no que diz respeito a explicação para tal capacidade. A teoria da menstruação retrógrada é a mais antiga e aceita. Porém, ela não explica como algumas mulheres desenvolvem endometriose e outras não, visto que praticamente todas as mulheres apresentam algum grau de fluxo retrógrado. A migração celular desempenha papel central em ampla variedade de fenômenos biológicos e contribui para a progressão da maioria das doenças humanas. No organismo adulto, a migração permanece notável, sendo essencial para uma resposta imune adequada, reparo de feridas e homeostase tecidual. Entretanto, em várias doenças apresenta-se de forma anormal. No entanto, pouco se sabe sobre o papel dos mecanismos de motilidade celular para o estabelecimento e progressão dos implantes de endometriose. Diante disso, o estudo teve como objetivo avaliar a expressão de genes relacionados aos processos de motilidade celular em células primárias derivadas do endométrio de mulheres com endometriose profunda e mulheres sem a doença. As células do endométrio provenientes de mulheres com endometriose profunda apresentaram o gene CAV1 hiporregulado, gene relacionado à supressão de tumor e os genes RHOB e o PLD1 hiper-regulados, sendo esses genes envolvidos na migração e progressão celular. Nesse sentido, sugere-se que esses genes podem desempenhar um importante papel no estabelecimento e progressão da endometriose.
