AURKB and hepatocellular carcinoma: Our microarray‐based comparative genomic hybridization (array‐CGH) analysis on clinical samples showed that genomic instability was closely related to Aurora B overexpression in HCC.10 The fraction of genome altered (FGA) in Aurora B‐positive cases was significantly higher than that in Aurora B‐negative cases (P = .009), suggesting that overexpression of Aurora B may contribute to genomic instability in HCC.
