title: Epigenetic regulation of protein tyrosine phosphatases: potential molecular targets for cancer therapy.
abstract: Promoter methylation-mediated silencing is a hallmark of many established tumor suppressor genes. This review focuses on the methylation and suppression of a receptor-type tyrosine phosphatase gene, PTPRO, in a variety of solid and liquid tumors. In addition, PTPRO exhibits many other characteristics of a bona fide tumor suppressor. Reactivation of genes silenced by methylation using inhibitors of DNA methyltransferases and histone deacetylases, and the potential application of PTPRO as a molecular target for cancer therapy have been discussed.
