Transcription profiling by array of human breast cancer cell line MDA-MB-231 with siRNa against Runx2, CBF-beta or a non-specific siRNA

ABSTRACT: Cells of MDA-MB-231 breast cancer cell-line were transfected with siRNA against Runx2, CBF-beta or non-specific siRNA used as control. Runx2 is a member of the Runx transcription factor family and possesses a Runt domain capable of binding to the consensus DNA sequence ACC(A/G)CA. This domain also interacts with the co-activator protein core binding factor beta (CBF-beta), which enhances its binding to DNA. Runx2, primarily identified as a master regulator of bone development, but was also found expressed in the epithelium of the nascent mammary gland in mice. In contrast with its normal role in breast, it has been shown that Runx2 is over-expressed in breast cancer cell lines.
