Further inspection of the modules found that three of these modules are related to known breast cancer related processes such as epithelium development (Vincent-Salomon and Thiery, 2003), chromosome organization (Muleris et al., 1995), and mitotic cell cycle (Kastan and Bartek, 2004) including well-known breast cancers genes such as NCOA3, AURKA, MKI67, and FOXA1. Here, AURKA is linked to breast cancer.
