Many of the identified CNAs also included well-known cancer-related miRNA genes, including MIR92B (ch1q21), MIR30B (ch8q24), and MIR30D (ch8q24), whose frequent amplifications in lung adenocarcinoma have been reported previously [51], and many others that have not been reported previously (Fig. 6B). Here, MIR92B is linked to cancer.
