EZH2 and esophageal squamous cell carcinoma: These include linc-POU3F3, which is encoded by a genomic region next to POU3F3 and contributes to ESCC proliferation by reducing POU3F3 mRNA via enhancer of zeste homolog 2 (EZH2) [17] and lncRNA-uc002yug.2, which involves in the alternative splicing of RUNX1 by promoting the combination of RUNX1 and alternative splicing factors [18].
