Abstract: Objective To investigate the relationship between the expression of ING4 and clinical primary breast cancer.Methods Tissue and peripheral blood samples of primary breast cancer patients were collected and the expression levels of ING4 and NF-κB in tissue samples were detected with immunohistochemistry.The expression of ING4 in the peripheral blood was detected with ELISA.Results The positive rates of expression of ING4 and NF-κB in breast cancer tissues were 100.00 ％ (30/30),which were significantly higher than that in the adjacent tissues 12.50 ％ (3/24) and 93.75 ％ (45/48) compared to 6.67 ％ (1/15) respectively.Compared with the preoperative,the ING4 level in peripheral blood from the postoperative breast cancer patients was significantly reduced (P =0.044).Conclusions The expression of ING4 does not decrease in the primary breast cancer patients.The increasing is perhaps due to the body's stress response against tumor development in early stage by secreting more ING4 protein.
