Abstract 977: RNA-sequencing analysis implicates novel non-coding RNAs in human papillomavirus-associated head and neck squamous cell carcinoma

Head and neck squamous cell carcinoma (HNSCC) is an aggressive disease marked by frequent recurrence and metastasis and stagnant survival rates. Given the recent emergence of human papillomavirus (HPV) as a major etiological factor in head and neck cancers, there exists a pressing need to better resolve the molecular heterogeneity of HNSCCs, define more precise diagnostic and prognostic tools, and develop a wider repertoire of targeted therapies. Non-coding RNAs (ncRNAs), including long non-coding RNAs (lncRNAs) and microRNAs (miRNAs), have been increasingly viewed as promising sources of insight into cancer onset and progression, with their diverse regulatory roles, tissue specificity, and aberrant expression in various human diseases now established by a multitude of studies. Using RNA-sequencing data from 466 HNSCC patients in The Cancer Genome Atlas (TCGA), we sought to investigate the transcriptome-wide dysregulation of both classes of ncRNAs in HPV-associated HNSCCs. Differential expression analyses controlled for patient smoking status revealed 5 lncRNAs and 9 miRNAs exhibiting significantly altered regulation between HPV-negative and HPV-positive HNSCC tumors (FDR Citation Format: Angela E.
