SRSF1 and small cell lung carcinoma: 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).
