Interestingly, as shown in Supplementary Figure S1, a significant induction of octamer binding complexes with electrophoretic mobility similar to Oct-6 (as observed in the H460 cells used in these EMSAs as a control) was also detected in other human cancer cell lines of different tissue origin, suggesting that the Dox-mediated induction of Oct-6 was not restricted to the H460 NSCLC cell line. Here, POU3F1 is linked to cancer.
