A, Violin plot represents RAD51 log2 transformed expression among 520 HNSCC according to HPV status. B, RAD51 gene expression range among HPV-positive HNSCC samples evaluated. C, Kaplan-Meier plot shows a trend towards worse survival rates among HPV-positive HNSCC with higher Rad51 expression. D, Violin plot represents WEE1 log2 transformed expression among 520 HNSCC according to HPV status. E, WEE1 gene expression range among HPV-positive HNSCC samples evaluated. F, Kaplan-Meier plot shows worse survival among HPV-positive HNSCC with lower WEE1 expression.
