EZH2 and neoplasm: Expression levels of NEAT1 and GAS5 were also significantly increased in tumor samples compared with adjacent normal tissue (p-value = 2.16e−8 for GAS5 and p-value = 0.01 for NEAT1, t-test, Figure 3A), suggesting that they inhibit apoptosis in HCC, perhaps by interacting with EZH2 and JARID2.
