Research Abstract

The expression of SPA-1, one of the Rap1GAPs, was increased in metastatic tissues of human prostate cancer, compared with the primary sites. Based on the results, we found that SPA-1 protein promotes the invasion and metastasis of prostate cancer, by down-regulation of attachment to ECM through Rap1's inactivation and by suppressing transcription of ECM-asscociated genes through translocation of Brd4.
