Abstract: Objective To explore the correlation between progesterone receptor membrane component 1 (PGRMC1) and malignant proliferation of breast cancer. Methods The expression of PGRMC1 was detected immunohistochemically in 90 specimens of breast cancer (the median age was 47), 60 benign breast diseases (the median age was 45) and 60 cases of normal breast tissues from September 2017 to January 2019. All of them were women, and all tissues were diagnosed by the hollow needle biopsy or postoperative histologic examination. As a research project, all participants signed informed consent voluntarily.The pathological grade of breast cancer was determined viahematoxylin-eosin staining to determine. The association of PGRMC1 with pathological factors and the expression of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (Her-2), nuclear-associated antigen (Ki-67) was assessed. Results Positive expression of PGRMC1 was 63.33% (57/90) in breast cancer, 28.33% (17/60) in benign breast diseases and 6.67% (4/60) in normal breast tissues. PGRMC1 expression was significantly correlated to tumor size, lymphatic metastasis and the histological grade (P<0.001, respectively), PGRMC1 positive expression rate increased with the increase of histological grade of breast cancer, but not significantly correlated with menstruation in breast cancer (P>0.05). The expression of PGRMC1 in breast cancer group was related to the expression of ER, Ki-67, PR and Her-2 (P<0.05), which was most closely related to ER (r=0.461), followed by Ki-67 (r=0.330), but weakly correlated with the expression of PR and Ki-67(r=0.132,r=0.103, respectively). The expression of PGRMC1 in benign breast disease group was related to the expression of Ki-67 and Her-2 (P<0.05), and the correlation with the expression of Ki-67 (r=0.569) was higher than that of Her-2 (r=0.228). Conclusion PGRMC1 is highly expressed in breast cancer. PGRMC1 expression is strongly associated with the biological behavior of breast cancer. It may serve as a useful prognostic indicator of the malignancy. Meanwhile, it is found that PGRMC1 is closely related to ER expression in breast cancer, suggesting that PGRMC1 may potentiate estrogen signaling.
