Neurofibromatosis 2 (NF 2) is one of the tumor sup-pressor genes, and its disorder has been reported in sporadic meningiomas. We investigated some reduc-tion of expression of NF 2 protein and mRNA in 33 sporadic meningiomas, using immunohistochemistry and in situ hybridization, respectively. Seventeen of 33 (51.5%) meningiomas demonstrated significantly re-duced or absent NF 2 protein expression. Its mRNA was also reduced or absent in 11 of 24 (45.8%) men-ingiomas, and some statistically significant correlation was shown between reductions of NF 2 protein and its mRNA.
