SRSF1 gene over-expression in both Myc and N-Myc amplified SCLC cell lines and Myc amplified SCLC tumor patients, however, was not observed (p = 0.29 and p = 0.33, respectively), though the number of amplified cell lines or patient tumors with available gene expression data was sparse for each comparison (S9 Fig). Here, MYCN is linked to small cell lung carcinoma.
