Among the top 100 coexpressed genes with ARHGAP11A and ARHGAP11B, there were several genes in common, and most of them are involved in breast cancer, including (genes that contributed to breast cancer are shown with their corresponding references) BUB1B [38, 39], BUB1 [38, 40], KIF20A [38, 41], ASPM [42], TOP2A [43], CKAP2L [44], KIF23 [45], NUSAP1 [46], PRC1, SGOL1 [47], KIF11 [48], MKI67 [49], NCAPH [50], POLQ [51], RACGAP1 [52], KIF14 [53], KIF15 [54], MCM10 [55], CENPF [56], CASC5, STIL, CENPI, PLK4 [57], E2F8 [58], CLSPN [59], and GSG2 [60]. This evidence concerns the gene PLK4 and breast cancer.
