Abstract: Objective: To study the expression of tumor suppressor gene hypermethylated in cancer 1(HIC-1)and oncogene hyaluronan-mediated motility receptor (HMMR) in lobular hyperplasia of mammary gland, breast fibroadenoma and breast cancer, as well as their relationship with the clinicopathological parameters of breast cancer. Methods: Expressions of HIC-1 and HMMR was examined by immunohistochemistry on 57 resected tissue samples taken at breast surgery: lobular hyperplasia 17 cases, fibroadenoma 20 cases and breast cancer 20 cases. The staining results were assessed semi-quantitatively, and were analyzed with the clinicopathological parameters of breast cancer. Results: ① HIC-1 was mo-derately positive in lobular hyperplasia and fibroadenoma tissue (average score 5.65), and was weakly positive in breast cancer tissue(average score 2.15). The difference in expression of HIC-1 between mammary benign lesions and breast cancer was significant (P<0.001). ② Expression of HMMR in mammary benign lesions was low (average score of fibroadenoma was 0.3, average score of lobular hyperplasia was 0), while the expression of HMMR in breast cancer was with an average score of 2.3 (P<0.001). ③ No obvious correlation was observed between protein expression of HIC-1 and HMMR and cli-nicopathological parameters of breast cancer. Conclusions: Expression of tumor suppression gene HIC-1 is significantly low and oncogene HMMR is relatively high in breast cancer. HIC-1 and the downstream gene HMMR regulated by HIC-1 may be involved in the development and progress of breast cancer.
