The invention discloses the function of an IRF3 gene in atherosclerosis and an application of an inhibitor of the IRF3 gene, belonging to the field of the function and the application of a gene. According to the invention, ApoE- / -mice and IRF3- / -ApoE- / -mice are taken as experimental subjects, an atherosclerosis model is obtained through high-fat induction, AS model mouse plaque area measurement and inclusion analysis are performed, and the results show that the aorta plaque area of the IRF3- / -ApoE- / -mice is remarkably reduced in comparison with that of the ApoE- / -mice. The invention discloses the function of the IRF3 gene in an atherosclerosis disease, which means that the IRF3 gene has an effect of promoting the formation of the aorta plaques, especially that the IRF3 gene can worsen the atherosclerosis. According to the abovementioned function, the IRF3 can be used as a drug target for screening drugs for treating the atherosclerosis disease. The inhibitor of the IRF3 can be used for preparing the drug for treating the atherosclerosis disease.

The invention discloses application of interferon regulatory factor 4 (IRF4) gene in coronary atherosclerotic heart disease, belonging to the field of gene functions and applications. According to the application, IRF4 gene knockout mice and heart-specific IRF4 transgenic mice are taken as experimental subjects, and myocardial infarction model is constructed by blocking mouse heart left anterior descending coronary artery (LAD); results show that compared with a-MHC-Cre moue, the myocardial infarction area, myocardial hypertrophy and myocardial fibrosis degree of the IRF4 gene knockout mouse are remarkably increased, while the heart function of the heart-specific IRF4 transgenic mouse is remarkably improved. Therefore, the function of IRF4 gene in coronary atherosclerotic heart disease is mainly reflected in the protective effect of IRF4 gene on coronary atherosclerotic heart disease. Relative to the function of IRF4, the invention provides application of IRF4 in preparation of medicaments for treating coronary atherosclerotic heart disease.

The nucleotide sequence of the larimichthys crocea interferon regulatory factor IRF7 starter is shown as Seq ID No.1 or a nucleotide sequence complementary to Seq ID No.1. The invention further protects application of the starter or the nucleic acid builder or a carrier or a reconstitution cell or fish or a mammal containing the starter or the nucleic acid builder or the carrier or the reconstitution cell in regulating target gene expression or transgenic fish.

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 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.

The present invention relates to antisense oligonucleotides that modulate the expression of and / or function of Interferon Regulatory Factor 8 (IRF8), in particular, by targeting natural antisense polynucleotides of Interferon Regulatory Factor 8 (IRF8). The invention also relates to the identification of these antisense oligonucleotides and their use in treating diseases and disorders associated with the expression of IRF8.

The invention discloses interferon regulatory factor 9 (IRF9) and application of an inhibitor thereof in cerebral apoplexy, belonging to the field of gene function and application. The invention uses IRF9 gene knock-out mice and brain-specific IRF9 transgenic mice as experimental subjects and adopts middle cerebral artery ischemia reperfusion model, results show that compared with mild type C57 mouse, the brain infarction volume of IRF9 gene knock-out mouse is apparently inhibited, and nerve function is improve remarkably, while the infarction volume of nerve-specific IRF9 transgenic mouse is apparently inhibited, and nerve function is deteriorated markedly. Therefore, IRF9 gene has nervous system function deterioration effect; especially, IRF9 gene can deteriorate cerebral apoplexy. As for the above function of IRF9, the invention provides application of IRF9 as drug target of cerebral apoplexy treatment in developing medicaments for treating cerebral apoplexy.
