AB  - OBJECTIVE To study the expression level and clinical significance of HMGB1 and RAGE in cervical squamous epithelial carcinoma.METHODS Real time quantitative polymerase chain reaction (qRT-PCR) was employed to examine the expression of HMGB1 (high mobility group box protein1), and RAGE (receptor for advanced glycation endproducts) in 60 cervical squamous epithelial carcinomas (CSEC), their paraneoplastic tissues (PS) and 30 normal cervix tissues (NCS).RESULTS The expression of HMGB1 in the CSEC samples and PS was similar (P>0.05), but higher compared to NCS (P<0.05). Overexpression of HMGB1 in the CESC tissues was significantly correlated with the tumor (P<0.05), and the presence of metastasis (P<0.01), but not correlated with the tumor diameter or tumor grade. RAGE expression was not significantly different among these tissue types, and showed no significant correlation with the the tumor stage, diameter or grade. But there was a significant positive correlation between RAGE expression and CSEC metastasis.CONCLUSION The results suggest that HMGB1 may be related to the proliferation, progression and metastasis of CSEC. The relationship of HMGB1/RAGE may be of importance for CSEC metastasis. HMGB1 presents a new potential gene target for prevention and treatment of CSEC. Study of HMGB1/RAGE expression will offer an experimental foundation for understanding the pathogenesis of CSES.
