The evolution of the cancer cell into a metastatic entity is the major cause of
death in patients with cancer. It has been acknowledged that aberrant activation
of a latent embryonic program, known as the epithelial-mesenchymal transition
(EMT), can endow cancer cells with the migratory and invasive capabilities
associated with metastatic competence for which E-cadherin switch is a
well-established hallmark. Discerning the molecular mechanisms that regulate
E-cadherin expression is therefore critical for understanding tumor invasiveness
and metastasis. Here we report that SMAR1 overexpression inhibits EMT and
decelerates the migratory potential of breast cancer cells by up-regulating
E-cadherin in a bidirectional manner. While SMAR1-dependent transcriptional
repression of Slug by direct recruitment of SMAR1/HDAC1 complex to the matrix
attachment region site present in the Slug promoter restores E-cadherin
expression, SMAR1 also hinders E-cadherin-MDM2 interaction thereby reducing
ubiquitination and degradation of E-cadherin protein. Consistently, siRNA
knockdown of SMAR1 expression in these breast cancer cells results in a
coordinative action of Slug-mediated repression of E-cadherin transcription, as
well as degradation of E-cadherin protein through MDM2, up-regulating breast
cancer cell migration. These results indicate a crucial role for SMAR1 in
restraining breast cancer cell migration and suggest the candidature of this
scaffold matrix-associated region-binding protein as a tumor suppressor.
