This invention relates to compounds, compositions, and methods useful for modulating polycomb group protein EZH2 gene expression using short interfering nucleic acid (siNA) molecules. This invention also relates to compounds, compositions, and methods useful for modulating the expression and activity of other genes involved in pathways of polycomb group protein EZH2 gene expression and/or activity by RNA interference (RNAi) using small nucleic acid molecules. In particular, the instant invention features small nucleic acid molecules, such as short interfering nucleic acid (siNA), short interfering RNA (siRNA), double-stranded RNA (dsRNA), micro-RNA (miRNA), and short hairpin RNA (shRNA) molecules and methods used to modulate the expression of polycomb group protein EZH2 genes, such as EZH2.

The invention provides a full-length cDNA sequence of long chain non-encoding RNA for early diagnosis of human prostatic cancer and its application. An accurate sequence of the PRCAT38 is cloned for the first time, and a foundation for further studying the function of the PRCAT 38 in the generation and development processes of the prostatic cancer is laid. The specificity high expression of the PRCAT 38 in the prostatic cancer cells and tissues can influence the proliferation, clone formation and migration of the prostatic cancer cells, and the PRCAT 38 can be applied to prepare the product for the early diagnosis, prognosis evaluation and/or treatment of the prostatic cancer. The invention provides a cancer diagnosis marker, which comprises PRCAT 38, EZH2 and miR-24-2, the marker has highsensitivity and high specificity to detect prostate. The invention provides an expression inhibitor of the long chain non-encoding RNA, which comprises siRNA and/or shRNA; the expression inhibition can inhibit the expression of PRCAT38 and EZH2 at the same time, and is good for the gene treatment and clinical drug research and development of the prostatic cancer.

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.
