HPV-positive HNSCC cell lines are more sensitive to radiation than HPV-negative HNSCC cell lines. (A) The mRNA expressions of E6, E7, p16, p53 in FaDu, UM-SCC-4, UM-SCC-47 and UPCI-SCC-090 cell lines by RT-qPCR. (B) The protein expressions of E6, E7, p16, p53 in FaDu, UM-SCC-4, UM-SCC-47 and UPCI-SCC-090 cell lines by Western blot. (C, D, E) The different sensitivity to radiation among the FaDu, UM-SCC-4, UM-SCC-47 and UPCI-SCC-090 cell lines. *P < 0.05.
