These were pcdh8 (20/23 embryos by EBF2, 27/28 embryos by EBF3), peripherin (15/15, 35/35), greb1 (genes regulated by estrogen in breast cancer; 12/12, 10/10), nf-m (15/15, 35/38), kcnk5 (11/11, 39/40), nscl-1 (9/9, 33/40), neurod (20/21, 39/39), aml1 (12/12, 11/11), activin beta b (11/11, 37/40), and emx1 (11/13, 28/32) (Figure 1). This evidence concerns the gene KCNK5 and breast cancer.
