    Menstrual fluid from endometriosis patients shows distinct endometrial epithelial signatures detectable in RNA analysis.

  • 2

    A pilot study analyzed menstrual fluid from 5 endometriosis patients and 5 healthy controls using RNA sequencing.

  • 3

    The study identified 36 upregulated and 53 downregulated epithelial genes associated with endometriosis.

  • 4

    Five genes were differentially expressed in both single-nucleus and bulk RNA analyses, with KCNK5 as a potential biomarker.

  • 5

    The study's limitations include a small sample size and variability in menstrual fluid composition among donors.
