LINC01419 and hepatocellular carcinoma: We analyzed histone modifications in the LINC01419 promoter in HCC cells and detected strong enrichment of H3K27ac peaks in the promoter region of LINC01419 in Huh7 cells, which have high levels of LINC01419; conversely, no peaks were detected in Hep3B and SNU‐449 cells, which have extremely low LINC01419 expression (Figure 5D).
