Enhancer of zeste homologue 2 (EZH2) was found to be widely overexpressed in most T-cell lymphomas, such as NK/T-cell lymphoma (NK/TCL) [89], T-lymphoblastic lymphoma (T-LBL) [90], and adult T-cell leukaemia/lymphoma (ATLL) [91], and was associated with a high proliferation rate and correlated with MYC in ALK + and ALK- ALCL and pSTAT3 expression in ALK + ALCL [92]. Here, MYC is linked to T-cell non-Hodgkin lymphoma.
