Overcoming cetuximab resistance in HNSCC: The role of AURKB and DUSP proteins

ABSTRACT: Unraveling the underlying mechanisms of cetuximab resistance in head and neck squamous cell carcinoma (HNSCC) is of major importance as many tumors remain non-responsive or become resistant. Out microarray results suggest that resistant cells still exhibit RAS-MAPK pathway signaling contributing to drug resistance, as witnessed by low expression of DUSP 5 and DUSP6, negative regulators of ERK1/2, and increased expression of AURKB, a key regulator of mitosis. Therefore, interrupting the RAS-MAPK pathway by an ERK1/2 inhibitor (apigenin) or an AURKB inhibitor (barasertib) might be a new strategy for overcoming cetuximab resistance in HNSCC 4 head and neck squamous cell carcinoma (HNSCC) cell lines were treated with either 15 nM cetuximab or PBS during 13 hours. For each cell line, differen
