Purpose : The tumor suppressor gene PTEN/MMAC1 is mutated in a variety of advanced and metastatic cancers, strongly suggesting that PTEN/MMAC1 alterations may be involved in tumor progression and the formation of metastases. However, the roles of PTEN in tumor growth and metastasis and its functional mechanisms are not fully understood. We evaluated the tumor suppressor function of PTEN/MMAC1 gene... |
