As shown in Figures 1B–D), NLRC5, IL-6, and TNF-α were up-regulated in ectopic and eutopic ESCs of patients with endometriosis compared to that in the ESCs of patients with leiomyoma, and the levels of NLRC5, IL-6, and TNF-α in ectopic ESCs were also significantly higher than that in eutopic ESCs. Here, NLRC5 is linked to endometriosis.
