Description
Summary:This study aimed to investigate the HS-1-associated protein X-1 (HAX1) and Ki-67 expression in the breast cancer and its clinical significance. Breast cancer tissues and tumor-adjacent tissues were collected from 81 patients, and immunohistochemistry was conducted to detect the HAX1 and Ki-67 expression. The correlations of HAX1 expression with demographics, clinicopathological characteristics and prognosis were evaluated. HAX1 was highly expressed in the breast cancer, and its expression was related to the degree of breast cancer differentiation (P=0.002), lymph nodes metastasis (P=0.008) and progesterone receptor (PR) (P=0.021), but not with the age, tumor size, histological type, estrogen receptor (ER), HER2 and p53. HAX1 expression was positively related to Ki-67 expression in the breast cancer (r(2)=0.394, P=0.019). In addition, a higher HAX-1 expression was related to a lower 10-year survival rate. HAX1 is a new protein related to the breast cancer and probably plays an important role in the invasion and metastasis of breast cancer. Thus, HAX1 may be used as a potential target for the therapy of breast cancer.
