The tumor suppressor gene, PTEN, has previously been demonstrated to be involved in breast tumorigenesis and tumor progression. The aim of the present study was to investigate the expression and significance of PTEN in breast carcinomas, to detect the mutation frequency of PTEN in sporadic breast carcinoma tissues and to determine the association between PTEN promoter methylation and gene expression....
