The invention belongs to the technical field of biology, and particularly relates to an EZH2 variable splicing site and an application thereof. Specific siRNA is used for knocking down two subtypes ofEZH2-L and EZH2-S respectively, and myocardial hypertrophy and heart failure models are established at the cellular level and the animal level respectively. Results show that after the EZH2-L is knocked down, the expression level of a myocardial hypertrophy pathological gene is obviously reduced, the myocardial cell area is reduced, and the heart weight is reduced; and after the EZH2-S is knockeddown, the expression level of the myocardial hypertrophy pathological gene is remarkably increased, the myocardial cell area is increased, the heart weight is increased, and the situation prompts that the EZH2-L and the EZH2-S have the effects of promoting and inhibiting myocardial hypertrophy and heart failure respectively. In addition, after the EZH2-L is knocked down, tumor cell proliferationis inhibited, and knock-down of the EZH2-S has no influence on tumor cell proliferation. The invention provides a new target and a new strategy for research and development of medicines for treating EZH2 gene related diseases.
