Compared to these normal lung tissues, SRSF1 was overexpressed in 65% (70/107; p<0.0001 versus normal) of NSCLC, with almost the same frequency in adenocarcinoma (ADC; 34/54; 63%; p<0.0001 versus normal) and squamous cell carcinoma (SCC; 36/53; 68%; p<0.0001 versus normal) (Figure 1A & Figure S1; Table 2). Here, SRSF1 is linked to adenocarcinoma.
