It should be noted, however, that these differences might be influenced by individual characteristics of patients from whom the endometrial material was obtained: their endocrine profile, age, peculiarities of endometriosis progression, concurrent diseases, etc. The literature reviews describe research that has found that the activation of KISS1R by KISS1 inhibits cell mobility, including proliferation, invasion, chemiotaxis, and metastasis formation [43,44,45,46]. The gene discussed is KISS1R; the disease is endometriosis.
