Full size ... WebOct 28, 2024 · Inhibition of Wee1, which is known to be overexpressed in HPV-positive head and neck squamous cell carcinoma (HNSCC), has been shown to sensitize tumor cells to cytotoxic agent such as cisplatin 12 – 15. Because Wee1 is essential for cell survival in p53-mutant HNSCC cells, the treatment with AZD1775 leads to the death of those tumor cells.
