"Although mutation of APC or CTNNB1 ( beta- catenin) is rare in breast cancer, activation of Wnt signalling is nonetheless thought to play an important role in breast tumorigenesis, and epigenetic silencing of Wnt antagonist genes, including the secreted frizzled- related protein ( SFRP) and Dickkopf ( DKK) families, has been observed in various tumours. In breast cancer, frequent methylation and silencing of SFRP1 was recently documented; however, altered expression of other Wnt antagonist genes is largely unknown," scientists in Sapporo, Japan report. "In the present study, we found frequent methylation of SFRP family genes in breast cancer cell lines ( SFRP1, 7 out...
