METHODS Immunohistochemical staining of tissue microarrays and Western blot analysis were conducted to detect the expression of HMGB1 in the following tissue samples: 30 carcinoma in situ, 90 invasive CSEC without metastasis, 30 invasive CSEC with metastasis, 30 cases of normal cervical squamous epithelia. RESULTS The positive-expression rate of HMGB1 was 58.7% (88/150) in CSEC, showing a significant difference compared to normal cervical squamous epithelia. The expression of HMGB1 was correlated with tumor size, invasion and metastasis of CSEC (respectively, P〈0.01), but had no relationship with the degree of differentiation (P〉0.05). CONCLUSION The over-expression of HMGB1 in CSEC might be a useful parameter as an indication of tumor invasion, metastasis, prognosis and overall biological behavior of human CSEC, as well as a noval target site for gene therapy.展开更多
