Ets proteins are transcription factors, which share a unique DNA binding domain, the Ets domain. Some members of the Ets family are implicated in tumorigenesis. Ets1, the founder of the Ets family, is predominantly expressed in invasive tumors and able to activate certain genes encoding ECM-degrading proteases. We used RNA-interference in combination with DNA chip analysis to identify Ets1-regulated genes in MDA-MB-231 breast cancer cells. Of the Ets1-responsive proteases, matrix metalloproteases MMP1 and MMP9, but not MMP3 or uPA, showed reduced RNA levels when endogenous Ets1 expression was suppressed. These data suggest that Ets1 regulates only a certain subset of ECM-degrading proteases. How Ets1 is regulated in invasive breast cancer cells is unknown. The observations that protein kinase C inhibitors abrogated Ets1 expression and that protein kinase C was able to increase Ets1-dependent transcription imply that protein kinase C is a potential regulator of Ets1 activity in breast cancer cells.
