Not surprisingly, SCLC-A/N MSK900b and SCLC-A MSK761, which have consistently clustered with the SCLC-P cohort, also expressed high levels of MYC but did not express MYCN or MYCL. Most of the SCLC-A samples showed expression of MYCL, consistent with the previous reports39. This evidence concerns the gene MYC and small cell lung carcinoma.
