The redox regulatory protein, thioredoxin-interacting protein (TXNIP), has been confirmed as an important tumor suppressor gene in various types of human cancers. In previous studies, we found that overexpression of tumor suppressor gene RIZ1 in meningiomas can significantly improve the expression of TXNIP by microarray data analysis. Therefore, we hypothesized that TXNIP was associated with the initiation and progression of meningiomas.


First, we evaluated the expression of TXNIP and Ki-67 in meningioma tissues from 65 patients using immunohistochemistry. We also analyzed the correlation between TXNIP immunoreactivity and clinicopathological features, as well as patient prognostic factors.


According to immunohistochemistry results, high-grade meningioma tissues had significantly lower expression of TXNIP than benign meningioma tissues (29.31 ± 18.70 vs 74.61 ± 7.51, P < 0.0001). TXNIP and Ki67 were negatively correlated (P < 0.0001). Moreover, the expression of TXNIP was higher in nonrecurrent high-grade meningiomas (P < 0.05). In addition, Kaplan–Meier analysis indicated that expression of TXNIP and Ki-67 was related to recurrence-free time. Multivariate Cox analysis showed that TXNIP expression level was the only independent predictor for meningioma prognosis.


Our results demonstrated that high expression of TXNIP indicates a lower pathological grade of meningnioma, and is also associated with longer recurrence-free time. Therefore, TXNIP could be regarded as a potential molecular marker to predict recurrence in patients with meningiomas.
