In this study, we screened 1161 FDA-approved compounds to identify agents that induce reactive oxygen species (ROS) accumulation in head and neck squamous cell carcinoma (HNSCC) cells. Pimozide, a dopamine D2 receptor antagonist, emerged as the most potent ROS inducer. It selectively suppresses the growth of HNSCC cells with high oxidative stress resistance while exhibiting only modest effects on less resistant cells and normal keratinocytes. Notably, pimozide exhibited anti-tumor effects as a monotherapy and in combination with paclitaxel at clinically relevant doses. Mechanistic analysis revealed that pimozide rapidly induced ROS accumulation via a mechanism distinct from its known action on dopamine D2 receptors and STAT3/5. To identify markers of ROS-induced responses, we examined ROS-responsive genes and found that early growth response 1 (EGR1) was selectively induced in sensitive cells and correlated with pimozide responsiveness. Functional analysis revealed that EGR1 knockdown suppressed pimozide-induced cytotoxicity, suggesting its role as a functional pharmacodynamic marker of pimozide sensitivity. In a patient-derived xenograft model of HNSCC, pimozide significantly reduced the tumor burden alone and in combination with paclitaxel. While tumor volume reduction in the combination group was not statistically greater than that in the monotherapy group, fluorescence immunohistochemistry revealed a marked decrease in undifferentiated tumor cells, indicating enhanced therapeutic effects of combination treatment.

The protein stabilization of mutant p53 (mutp53) is a prerequisite for gain-of-function manifestation. Here, we report the novel mechanism that pyruvate dehydrogenase kinase1 (PDK1) modulates both wild-type and mutant p53, and facilitates proliferation and migration of TP53 mutant breast cancer. On the one hand, we identified PDK1 as a direct transcriptional repression target of wild-type p53, whereas transcriptional activation of PDK1 in mutp53 cells is initiated by the EGR1 axis. On the other hand, PDK1 promoted mutp53 protein accumulation by binding to mutp53 and inhibiting its degradation. Taken together, mutp53 activated a positive feedback loop by upregulating PDK1 to enhance p53 protein stability and promote the malignancy of breast cancer. Moreover, PDK1 inhibition increased the therapeutic effect of APR-246 on TP53 mutant breast cancer in xenograft tumors.
