Abstract:
Objective To investigate the expression of Survivin,receptor for advanced glycation endproduct(RAGE) and high mobility group protein B1 (HMGB1) gene in human breast cancer and their clinical significance.Methods The expression of Survivin,RAGE and HMGB1 gene was detected by Real-time PCR technology and fluorescence in situ hybridization (FISH) technology in the following tissue samples:50 early breast cancers,50 advanced breast cancers,and the corresponding adjacent normal mammary tissues.The relationship of their expression and several factors such as differentiation degree,invasion,lymph node metastasis and TNM stage of cancer was explored.Results The positive expression rate of Survivin,RAGE and HMGB1 gene was 62％,73％ and 79％ detected by Real-time PCR technology,78％,69％ and 72％ detected by FISH technology in breast cancer tissues.The overexpression of these genes was positively correlated with TNM stage and lymph node metastasis.The expression of Survivin gene was positively correlated with the expression of RAGE and HMGB1.Conclusion Overexpression of Survivin,RAGE and HMGB1 gene is of great significance in early diagnosis and prognosis of human breast cancer.
