Expression of HLA-G mRNA and protein in ectopic and eutopic endometrium in patients with endometriosis / 解放军医学杂志

ABSTRACT

Objective To investigate the expression of human leucocyte antigen-G (HLA-G) in the endometrium of patients with endometriosis (EM). Methods The expression of HLA-G protein was detected in ovarian endometriosis (OEM) and adenomyosis (AM) using immunohistochemistry method, and the expression of HLA-G mRNA was detected using in situ hybridization technique (ISH), to compare with that in the endometrium of hysteromyoma as the control group. Results The rate of positive HLA-G expression in EM (including AM and OEM) was significantly higher than that in control group (P0.05). The expression of HLA-G protein showed no relation with different clinical phase or different endometrial cycle. Conclusion HLA-G is overexpressed in EM, which may play certain role in the pathogenesis of the disease.
