AURKA and ovarian cancer: In a query of over 400 ovarian cancer tumors in TCGA [56], using the cBioPortal (www.cbioportal.org), we determined that copy number alterations of PARP1 and AURKA were often observed in the same tumors (Figure 6A) and observed a significant tendency towards co-occurrence in a mutual exclusivity analysis (Figure 6B, P= 0.043).
