Global proteomic analysis of OPCs.
A, Kaplan–Meier estimates of overall survival among OPC patients in the discovery cohort according to HPV status. B, outline of the experimental workflow for in-depth proteomic analysis of FFPE OPC tissues. C, number of protein groups identified in HPV+ and HPV− OPCs. D, cellular component Gene Ontology (GO) term enrichment analysis for proteins identified in HPV+ and HPV− OPCs (p > 0.999, Pearson's χ2 test). Select terms with FDR < 0.05 are shown.
