# The Prognosis of Endometriosis Correlates With Elevated Expression of LncRNA-ANRIL

## TL;DR

This study finds that elevated levels of the lncRNA ANRIL are linked to the progression of endometriosis, a chronic gynecological condition.

## Contribution

The study identifies lncRNA-ANRIL as a potential biomarker for endometriosis prognosis and progression.

## Key findings

- ANRIL expression is significantly higher in endometriosis tissues compared to normal ovarian tissues.
- ANRIL expression correlates with the stage of endometriosis.
- ANRIL knockdown affects the migration and invasion of endometriosis cells.

## Abstract

Background: Endometriosis is a chronic condition that affects the endometrium, the lining of the uterus. The endometrium typically thickens and discharges during the menstrual cycle, resulting in menstruation. Endometriosis is characterized by developing endometrial-like tissue outside of the uterus, typically on the ovaries, fallopian tubes, and other pelvic structures. This tissue can become inflamed, resulting in various symptoms, such as discomfort. Endometriosis is characterized by heavy menstrual bleeding, fatigue, painful urination or bowel movements, and infertility. Endometriosis is a benign pathological condition frequently seen in the gynecology department. This study classified 28 lncRNAs associated with endometriosis and other gynecological disorders and examined the expression of lncRNA-ANRIL in the eutopic and ectopic endometrium of patients with Ems.

Methods: Quantitative reverse transcription (qRT)-PCR was utilized to explore the differences in ANRIL expression between endometriosis tissues and normal ovarian epithelium. Using this technique, the expression of ANRIL in vivo was assessed in 30 endometriosis specimens. A human endometriosis cell line was subjected to in vitro ANRIL knockdown so that the biological roles of the line could be discovered. The Transwell assay was successful in identifying migration and invasion.

Results: The expression of ANRIL was much higher in endometriosis tissues than in normal ovarian epithelial tissues, and this difference was found to be strongly associated with the endometriosis stage.

Conclusions: There was a positive correlation between the expression of ANRIL and the occurrence of endometriosis. Additionally, there was a close association between the expression of ANRIL and the etiology and development of endometriosis. This offers a potential basis for the early detection and treatment of endometriosis.
