Abstract 151: Transcriptome-wide expression profiling of long noncoding and small nucleolar RNAs in head and neck squamous cell carcinomas identifies novel transcripts associated with survival

Head and neck squamous cell carcinoma (HNSCC) persists as one of the most common and deadly malignancies, with early detection and effective treatment still posing formidable challenges. To expand our currently sparse knowledge of the epigenetic alterations involved in this disease and identify potential biomarkers and therapeutic targets, we globally profiled the dysregulation of small nucleolar (snoRNA) and long non-coding RNAs (lncRNA) in head and neck tumors. Using next-generation RNA-sequencing data from 40 pairs of tumor and matched normal tissues, we profiled lncRNA expression by mapping each RNA-seq library to a reference annotation containing 32,108 lncRNAs. Using edgeR, we found 19,681 lncRNA transcripts significantly differentially expressed by a fold change magnitude ≥ 4 with a false discovery rate Note: This abstract was not presented at the meeting.
