We report the application of single-molecule-based sequencing technology for high-throughput profiling of lncRNAs expression profile in sorafenib resistant hepatocellular carcinoma cells. We identified 1240 differentially expressed lncRNAs with 576 up-regulated and 664 down-regulated (fold change > 2, P < 0.05) in sorafenib-resistant (HUH7-S) HCC cells (fold change > 2, P < 0.05) in sorafenib-resistant (HepG2-S) HCC cells, compared to parental sorafenib-sensitive (HUH7, HepG2) HCC cells by high-throughput sequencing. In addition, based on GO (Gene Ontology) term enrichment analysis, these differentially expressed lncRNAs are mainly related to binding and catalytic activity and biological regulation of metabolic processes in both the Huh7-S and HepG2-S cell lines compared to parental cell lines. Moreover, the differentially expressed genes analyzed by KEGG (Kyoto Encyclopedia of Genes and Genomes) Pathway were significantly related to tight junction. Among them, TCONS_00284048 and TCONS_00006019 expression were consistently up-regulated in resistant HCC cells, whereas both of them knock down increased the sensitivity of Huh7-S and HepG2-S cells to sorafenib.
