Abstract

The widely accepted theory of endometriosis posits that endometriosis stems from the translocation of endometrial tissue through the fallopian tubes into the abdominal cavity. However, the exact pathogenesis and critical molecules of endometriosis remain unclear. Here, we find that alanyl-tRNA synthetase 1 (AARS1) is abundantly expressed in endometrial tissues and promotes the proliferation, migratory capability, and invasive potential in endometriotic stromal cells (EESC) and 11Z cells. Moreover, AARS1 enhances epithelial-to-mesenchymal transition in EESC and 11Z cells. In addition, AARS1 could lactylate Snail1 to maintain its protein stability. In summary, this work identifies a crucial role of AARS1 in advancing endometriosis, which may provide new insights into its pathogenesis and future disease management.
