The imprint of viral oncoproteins on the variable clinical behavior among human papilloma virus-related oropharyngeal squamous cell carcinomas
Human papilloma virus-related (HPV+) oropharyngeal squamous cell carcinomas (OPSCCs) are variable in their progression, immune landscape, treatment responses, and clinical outcomes. Their behavior is impacted not only by differences in host genomic alterations but also by diversity in levels and activity of HPV-encoded oncoproteins. Striking differences in HPV mRNA levels are found among HPV+ OPSCCs and likely derive in part from variations in the structurally diverse mix of integrated and episomal HPV genomes they often contain. Viral oncoprotein levels and function are also impacted by differential splicing of the two long polycistronic transcripts of HPV16, the HPV type within most HPV+ OPSCCs. Further variation in viral oncoprotein function arises from the distinct lineages and sub-lineages of HPV16, which encode polymorphisms in functionally important portions of oncogenes. Here we review the limited current knowledge linking HPV mRNA expression and splicing to differences in oncoprotein function that likely influence OPSCC behavior. We also summarize the evolving understanding of HPV16 physical genome state and genetic variants and their potential contributions to HPV oncoprotein levels and function. Addressing considerable remaining challenges in defining the quantitative and qualitative imprint of HPV oncoproteins on each OPSCC holds promise to guide personalization of therapy for this disease.
