CUX1 and breast cancer: As previously discussed, Affymetrix microarrays do not have a relevant probe for CUX1 (Sansregret et al., 2011), but the Oncomine database still contained three breast cancer datasets with data on CUX1 expression (Esserman et al., 2012; Glück et al., 2012; Cancer Genome Atlas Network, 2012).
