NFKB1 and endometriosis: Genistein (0.78 and 1.3 mg/day) significantly decreased the expressions of NF-κB and COX-2 in mice model of endometriosis (p < 0.05). Both positive controls, leuprolide acetate (0.00975 mg) and dienogest (0.0052 mg) decreased the expression of NF-κB and COX-2, but no significant difference as compared with endometriosis group (p > 0.05)
