Endometriotic Cells Exhibit Metaplastic Change and Oxidative DNA Damage as Well as Decreased Function, Compared to Normal Endometrium
Endometriotic cells exhibit metaplasia and oxidative DNA damage, along with decreased expression of TGFβ-1 and IGF-I, compared to normal endometrium.

The study compared normal endometrium with endometriotic tissue, assessing placental cadherin (P-cadherin) as a marker linked to metaplasia and early neoplasia, and 8-hydroxyguanine as an indicator of oxidative DNA damage. Using immunolabeling, the authors reported no detectable labeling for anti-P-cadherin or anti-8-hydroxydeoxyguanosine in normal endometrium, while endometriotic epithelium showed marked labeling on the apical surface. Markers associated with normal endometrial function, measured by de-expressed transforming growth factor β-1 (TGFβ-1) and insulin-like growth factor-I (IGF-I), were reduced in endometriosis, leading the authors to conclude that endometriosis cells exhibit metaplastic change, oxidative DNA damage, and markedly decreased function. This paper is centrally about endometriosis — it directly compares endometriotic tissue to normal endometrium for evidence of metaplasia, oxidative DNA damage, and reduced functional marker expression.
