Abstract:

Objective

To investigate serum microRNAs (miRNAs) in women with endometriosis.

Design

Case-control study.

Setting

University hospital.

Patient(s)

Women with (n = 24) and without (n = 24) endometriosis.

Intervention(s)

Serum samples were obtained from surgically diagnosed subjects.

Main Outcome Measure(s)

miRNA from women with without endometriosis were used for microarray profiling and confirmed by means of quantitative real-time polymerase chain reaction (qRT-PCR). Receiver operating characteristic (ROC) analysis was performed on differentially expressed miRNAs.

Result(s)

miR-3613-5p, miR-6755-3p were down-regulated and miR-125b-5p, miR-150–5p, miR-342-3p, miR-143-3p, miR-145-5p, miR-500a-3p, miR-451a, miR-18a-5p were up-regulated more than 10-fold in the microarray. These results were confirmed with the use of qRT-PCR. Among the differentially expressed miRNAs, miR-125b-5p expression levels had the highest area under the ROC curve (AUC). The maximum AUC score of 1.000 was achieved when combining miR-125b-5p, miR-451a, and miR-3613-5p with the use of a logistic regression model.

Conclusion(s)

We identified several miRNAs in serum that distinguished subjects with endometriosis from those without. miR-125b-5p had the greatest potential as a single diagnostic biomarker. A combination of that miRNA with miR-451a and miR-3613-5p further improved diagnostic performance.

miRna work can be discovery driven or agnostic. Does anyone know how this compares to other studies?
