The invention discloses a function and application of an interferon regulatory factor 4 (IRF4) in scaffold and endarterectomy restenosis, belonging to the field of gene functions and applications. According to the application disclosed by the invention, IRF4 gene knockout mice and mild C57 mice are taken as experimental subjects, and a vascular injury model is adopted to carry out neointima formation determination, vascular wall cell proliferation level detection and smooth muscle cell phenotype detection of a vascular injury model mouse; results show that compared with the mild mouse, the IRF4 gene knockout mouse has more distinct neointima formation and cell proliferation, which indicates that the function of the IRF4 gene in scaffold and endarterectomy restenosis is manifested by that the IRF4 gene has effect of inhibiting restenosis caused by vascular injury, especially protecting scaffold and endarterectomy restenosis. As for the function of IRF4, the IRF4 can be used for preparing medicaments for treating angiostenosis, especially medicaments for treating scaffold and endarterectomy restenosis.

The invention discloses an application of an interferon regulatory factor 5(IRF5) and an inhibitor thereof in treating cardiac hypertrophy, and belongs to the filed of function and application of genes. The application of the interferon regulatory factor 5(IRF5) and the inhibitor thereof in treating cardiac hypertrophy determines the relationships between the expression of IRF5 genes and cardiac hypertrophy disease. The relationships are inhibiting the expression of the IRF5 genes, accordingly remarkably inhibiting cardiac hypertrophy and fibrosis, and improving cardiac function; promoting the expression of the IRF5 genes, accordingly remarkably promoting cardiac hypertrophy and fibrosis, and deteriorating cardiac function. Thereby, IRF5 can be adopted as a drug target used for screening drugs which protect cardiac function, prevent, relieve and / or treat cardiac hypertrophy and resist myocardial fibrosis. The inhibitor of IRF5 can be used for preparing drugs which protect cardiac function, prevent, relieve and / or treat cardiac hypertrophy and resist myocardial fibrosis.

The invention provides a bicistronic DNA vaccine for grouper viral neuronecrosis, which is a recombinant eukaryotic expression vector, and the recombinant eukaryotic expression vector can simultaneously express the P-domain of neuronecrosis virus capsid protein and the superfamily domain of the grouper interferon regulatory factor 3 protein. The anti-necrosis virus bicistronic DNA vaccine prepared by the invention can well express the neuronecrosis virus capsid protein P-domain and the superfamily domain of the host's interferon regulatory factor 3 protein when transfected into fish. The prepared anti-neuronecrosis virus bicistronic DNA vaccine enhances the ability of fish to resist nerve necrosis virus infection, reduces the mortality rate of fish infected with the virus, enhances the humoral immunity of fish caused by the vaccine, and causes fish body The comprehensive immune response provides a good immune protection effect for the fish body.
