Targeting Aurora A to Overcome Cisplatin Resistance in Head and Neck Cancer.

ABSTRACT: Cisplatin-based chemotherapy is a cornerstone treatment for advanced recurrent head and neck squamous cell carcinoma (HNSCC). However, the effectiveness of the treatment is often hindered by intrinsic and acquired resistance and associated toxicity, highlighting a pressing unmet clinical need. Here, our compound screening identified Aurora kinase inhibitors, particularly those targeting Aurora A kinase, as potential agents to sensitize resistant HNSCC cells to cisplatin. While Aurora kinases are well-established regulators of mitosis, their precise role in cisplatin resistance is largely unknown, given that cisplatin confers toxicity primarily in cells undergoing DNA replication. We confirmed that depletion of Aurora A or its activators enhanced cisplatin response in resistant HNSCC cells.
