SRSF2 and non-small cell lung carcinoma: Similarly, and compared to normal lung tissues, a moderate (class 1, scores ranging from 100 to 175) or strong (class 2, scores ranging from 176 to 300) P-SRSF2 immunostaining was observed in 82/107 (77%) NSCLC, including 40/54 (74%) ADC and 42/53 (79%) SCC (p<0.0001 versus normal; Table 2 and Figure 1A).
