Thyroid Carcinoma (THCA) clinical information, mRNA and microRNA data expression data were downloaded from The Cancer Genome Atlas (TCGA) online platform (https://tcga-data.nci.nih.gov/tcga/), as January 2016. Mutations data were retrieved through cBioPortal49. LncRNA RPKM expression levels corresponding to TCGA patients were downloaded through TANRIC50, which obtained the genomic coordinates of 13,870 human lncRNAs from the GENCODE Resource (version 19)51 and further filtered out those lncRNA exons that overlapped with any known coding genes based on the gene annotations of GENCODE and RefGene, resulting in 12,727 lncRNAs50.
