Expression of the candidate invasion suppressor gene, nm23, in human brain tumors

Abstract
The nm23 genes encode a family of multifunctional proteins with well‐documented enzymatic and DNA‐binding functions. There are five isoforms of nm23 of which two, nm23‐H1 and nm23‐H2 have been widely studied within the context of metastasis suppression in a large variety of human cancers. However, the role of nm23 in mediating the invasive behavior of central nervous system neoplasms remains to be clarified. In the present study, we provide evidence that nm23 may suppress the invasive phenotype in primary human brain tumors.
