Despite the fact that Src is a potent Stat3 activator, Src418 levels did not increase with density in T51B or E10 cells, or in the NSCLC lines SK-LuCi6 (Figure 1A) and QUDB that have low Src levels, before or after expression of activated Src (lines T51B-Src, E10-Src, SK-LuCi6-Src and QUDB-Src, respectively). The gene discussed is STAT3; the disease is non-small cell lung carcinoma.
