Overexpression of high mobility group box 1 (HMGB1) has no correlation with the prognosis in glioma

Abstract

Aim: We aimed to characterize the role of HMGB1 overexpression in glioma and to evaluate its use as a biomarker. Materials & methods: We used the gene expression datasets and tissue microarray to assess the expression levels of HMGB1 among gliomas of all grades; We then assessed its correlation with the malignancy and outcome of glioma. Results: The increase in HMGB1 mRNA and protein levels was found in glioma, but there was no correlation between HMGB1 expression and glioma malignancy, and overall survival and vital status of glioma patients. Conclusion: Overexpression of HMGB1 is not associated with the malignancy and outcome in glioma. And it is not the valuable biomarker for the early diagnosis of glioma.
