EZH2 is the functional enzymatic component of polycomb repressive complex‐2 (PRC2) that is involved in health embryonic development through the epigenetic maintenance of genes responsible for regulating development and differentiation.12 It has been reported that EZH2 expression was elevated in cancer tissues in comparison with normal tissues, which contributed to poor prognosis in patients.13 Wen et al14 discovered that EZH2 was upregulated in LUAD cells and promoted LUAD cell invasiveness and metastasis. Here, EZH2 is linked to cancer.
