AQP1 and systemic lupus erythematosus: A low AQP1 level was linked to oocyte meiosis, cell cycle, base excision repair, and ubiquitin-mediated proteolysis (Figure 6A), and its high level was linked to VEGF signaling pathway, PPAR signaling pathway, complement and coagulation cascades, and systemic lupus erythematosus (Figure 6B).
