Breast cancer is the leading cause of cancer death in women worldwide which is closely related to metastasis. But the exact molecular mechanism of metastasis is still not fully understood. We now report that both
MRTF-A
and STAT3 play important roles in migration of MDA-MB-231 breast cancer cells. Moreover,
MRTF-A
and STAT3 synergistically increased MDA-MB-231 cell migration by promoting the expression of migration markers urokinase-type plasminogen activator (uPA) and osteopontin (OPN) and inhibiting the expression of breast cancer metastasis suppressor 1 (BRMS1). Luciferase reporter assays demonstrated that
MRTF-A
and STAT3 do not affect transcription of the BRMS1 promoter. Instead, we identified a newly molecular mechanism by which
MRTF-A
and STAT3 synergistically controlled MDA-MB-231 cell migration by recruiting DNMT1 to hypermethylate the promoter of BRMS1 and thus affect the expression of BRMS1. Interestingly, physical interaction between
MRTF-A
and STAT3 synergistically promotes the transactivity of DNMT1 by binding to the
GAS
element within the DNMT1 promoter. Our data thus provide important and novel insights into the roles of
MRTF-A
and STAT3 in regulating MDA-MB-231 cell migration.
