In a murine endometriosis model, established by surgically inducing endometriotic‐like lesions, niclosamide (100 and 200 mg·kg−1, p.o.)decreased the growth rate and progression of endometriosis‐like lesions and inhibited STAT3 and NF‐κB pathways (Prather et al., 2016). Here, STAT3 is linked to endometriosis.
