Mutually exclusive amplification of the three MYC family genes and the concurrent expression of two or three MYC family genes together, even though only one of them is amplified [14], imply the convenience of a common suppressing agent to all MYC proteins, MYC, MYCL and MYCN, to inhibit the growth of SCLC cells by MYC inhibition. Here, MYC is linked to small cell lung carcinoma.
