Moreover, our qRT-PCR-based expression analyses were also confirmed in FFPE of lung tissue obtained from NSCLC and SCLC patients stained with ITGB6- or ITGB2-specific antibodies (Figure 1G-H) and by Western Blot analysis (WB) of protein extracts from transfected A549, NCI-H82 and NCI-H196 cells (Figure 2A, top). Here, ITGB6 is linked to small cell lung carcinoma.
