ZWILCH and breast carcinoma: Figure 5 illustrates Metacore’s analysis of the interrelationships of the identified mitotic regulatory genes including STAG2, NEK2, KPNA4, IPO5, TNPO1, CCNB1, CDK1, CDK6, NCAPG, NCAPG2, TOP2A, NUF2, CENPE, CENPF, ZWILCH, PDS5A, WEE1, KIF11, CHUK, and PPP1CB. Of the 393 genes that were differentially expressed between the breast cancer and mammary epithelial cells following H’ to H analysis, approximately 80% of the top 60 most upregulated genes were histone clusters and non-protein coding RNAs such as small nucleolar-, ribosomal-, and micro-RNAs.
