Abstract
Endometriosis, defined as the abnormal growth of functional endometrium outside the uterus, is characterized by the abnormal phenotype of endometrial cells. This study aimed to investigate the role of latent transforming growth factor beta binding protein 2 (LTBP2), an extracellular matrix protein, in the occurrence and development of endometriosis. Elevated LTBP2 expression levels were observed in endometrial tissues and serum of endometriosis patients and their area under the ROC curve (AUC) values for distinguishing endometriosis were 0.9044 and 0.9534, respectively. Overexpressing-LTBP2 could promote proliferation, migration, and invasion, whereas suppressing apoptosis of endometrial stromal cells (ESCs). Moreover, LTBP2 downregulation induced the opposite effect. The supernatant from ESCs overexpressing LTBP2 promoted the tube formation of human umbilical vein endothelial cells (HUVECs), thus indicating an angiogenic effect. Furthermore, overexpression of LTBP2 facilitated the inflammation and might promote endometriosis progression through the NF-kB signaling pathway. Conclusively, LTBP2 might be a potential target in the diagnosis and treatment of endometriosis.
