Cowling et al., Mol Cell Biol 2007
(Breast Neoplasms...) :
Myc dependent repression of DKK1 and SFRP1 is accompanied by Wnt target gene activation and endogenous T-cell factor activity
Cho et al., J Biol Chem 2013
(Breast Neoplasms...) :
BMI1 mediated repression of DKK proteins ; in particular, DKK1 led to up-regulation of WNT target c-Myc , which in turn further led to transcriptional autoactivation of BMI1
