PAX5 was silenced or down‐regulated in seven out of eight (88%) NSCLC cell lines: silenced in A549, H292, H358, H1975 and down‐regulated in H1299, H1395, H1650, as show in Figure 1C. Two of each cell lines were chosen to verify the expression of mRNA compared with normal lung tissue samples via real‐time PCR (Fig. 1D). Here, PAX5 is linked to non-small cell lung carcinoma.
