Role of Serum Amyloid A1 (SAA1) in Endometrial Extracellular Matrix Remodeling in Polycystic Ovary Syndrome: Implication for Pregnancy Loss
Authors' conclusion
The locally elevated levels of SAA1 in endometrium contribute to ECM overdeposition by inducing collagen I synthesis in PCOS patients, which may hamper embryo implantation and increase the risk of pregnancy loss. These observations highlight the crucial role of heightened SAA1 in orchestrating endometrial dysfunction and shed light on potential therapeutic avenues for improving reproductive outcomes in PCOS patients.
Study context
- Population
- Polycystic ovary syndrome (PCOS) and control patients; human endometrial tissues and primary human endometrial stromal cells
- Comparison
- PCOS vs control patients
Main finding
As reported in the abstract
- Serum SAA1 concentration elevated in PCOS; independent risk of pregnancy loss in PCOS
- Increased SAA1 abundance in endometrium of PCOS patients
- SAA1 stimulated collagen I chain synthesis (COL1A1, COL1A2) in endometrial stromal cells
- Effect abolished by a toll-like receptor 2/4 antagonist or a nuclear factor κB inhibitor
