This study investigated whether inducing endometriosis in rats using diethylstilbestrol (DES) triggers an immune-inflammatory pathway, examining immune-inflammatory markers including NF-κB, MAPK, TNF-α, IL-6, and STAT-3. The authors report that DES-induced rats showed higher CA-125 levels and increased expression of these inflammatory mediators in the endometriosis-induced groups, concluding that DES induction operates through immune-inflammatory signaling. A key limitation is that the paper provides association of marker changes with model induction but does not describe additional mechanistic interventions or direct causal testing beyond marker measurement. This paper is centrally about endometriosis — it uses a DES rat model and links endometriosis induction to immune-inflammatory pathway activation.

Abstract

Endometriosis is a benign reproductive disorder distinguished by chronic inflammation and anomalous progress of stromal cells and glands outside the uterus. Though the etiology of endometriosis is still a matter of debate, the immuneinflammatory mediators are thought to play a major role. Macrophage infiltration and proinflammatory intermediaries in the peritoneal environment peritoneal milieu impact ovarian, uterine function and pelvic morphology, resulting in endometriosis symptoms and signs. The endometriosis model system was developed using diethylstilbestrol (DES) which is examined to develop the disease via the immune-inflammatory pathway. The immune-inflammatory markers (NFKB, MAPK, TNF-α, IL-6 and STAT- 3) were investigated in this study. The results demonstrated that the DES induced endometriosis animal model had a higher level of CA-125, a biomarker of endometriosis. Endometriosis-induced groups had increased levels of NFKB, MAPK, TNF-α, IL-6 and STAT-3 which clearly depicts the immune-inflammatory role in the induction. Finally, the results conclude that DES induced endometriosis via the immune-inflammatory pathway.
