Of 2,972 TUs, DE analysis retrieved 127 of Class 1 TUs significantly up-regulated in tumor specimens (adjusted P-value below 0.01, DESeq), including multiple intergenic transcripts and transcripts antisense to protein-coding genes, such as HDAC9, TPO, and FBXL7 (Table S3 and Fig S2B). This evidence concerns the gene HDAC9 and neoplasm.
