Runt-related transcription factor-2 regulation and transcriptional activity are linked with increased growth, invasion, and metastasis in breast cancer (Barnes et al, 2003), prostate cancer (Brubaker et al, 2003; Pratap et al, 2005), colorectal cancer (Wai et al, 2006), lymphoma, leukaemia and myeloma (Wotton et al, 2002; Castilla et al, 2004; Colla et al, 2005; Blyth et al, 2006). This evidence concerns the gene RUNX2 and prostate carcinoma.
