However, no significant changes in tumor weight were observed after erlotinib and/or AU‐1 treatment in #Rui‐4 models (low BPTF expression) (vehicle versus AU‐1; erlotinib versus erlotinib + AU‐1; vehicle versus erlotinib + AU‐1) (two‐tailed t‐test, NS, no significance; ***, p < 0.001) (Figure 8f). The gene discussed is BPTF; the disease is neoplasm.
