The morphologies of the SCLC cell lines are shown in Figure 1D. H209 cells with increased p-STAT3 and YAP protein expression exhibited an adherent growth pattern, and SCLC cell lines H146, H446, and H720 with low p-STAT3 and YAP protein expression exhibited a floating growth pattern (Figure 1D). This evidence concerns the gene YAP1 and small cell lung carcinoma.
