Low expression of BUB1B contributes to poor survival and metastasis in human colon adenocarcinomas [28] and several lung cancer cell lines [29], while overexpression of BUB1B is related to progression and recurrence of gastric cancer [30], bladder cancer [31], liver cancer [32], and many other cancers [33–35]. This evidence concerns the gene BUB1B and lung carcinoma.
