Enhancer zeste homolog 2 (EZH2), catalytic subunit of polycomb complex 2 (PRC2), which interacts with LINC00152 in lung adenocarcinoma [20] and the promotion of DNA methylation in ESCC cells by non-coding RNA POU3F3 [21], have drawn much attention in recent years due to their involvement in the development of human diseases, such as [22] lung cancer [23], gastric cancer [24], breast cancer [25], T-cell acute lymphoblastic leukemia [26], and pediatric soft tissue sarcomas [27]. This evidence concerns the gene EZH2 and T-cell acute lymphoblastic leukemia.
