Furthermore, an adeno-associated virus (AAV) carrying KAT14-shRNA was used in an endometriosis mice model to assess the role of KAT14 in vivo.<h4>Results</h4>KAT14 was upregulated in ectopic lesions from endometrioma patients and predominantly expressed in activated fibroblasts. The gene discussed is KAT14; the disease is endometriosis.
