Expression of seven hub genes in the mammary gland epithelial cell line and BC cell lines. The expression levels of CCNE2, CCNB1, CCNB2, BUB1B, TTK, CDC20 and PTTG1 were significantly higher in the BC cell lines (MCF-7 and MDA-MB-231) than in the MCF-10A cell line. *p<0.05, **p<0.01 and ***p<0.001.
