Abstract
Porcine reproductive and respiratory syndrome (PRRS) is one of the most economically devastating diseases affecting the global pig industry. Host microRNAs directly target viral gene regions to exert their disease-fighting effects. PRRS virus (PRRSV) infection upregulates miR-361-3p expression; however, it is unclear whether it can exert inhibitory effects by directly targeting viral genes. Bioinformatic and experimental findings revealed that miR-361-3p inhibited PRRSV replication by directly targeting the PRRSV ORF1b and ORF1a loci. Intramuscular injection of pcDNA3.1-pri-miR-361 verified the expression of miR-361-3p in mammals. In summary, miR-361-3p plays an important role in infection and may be a promising therapeutic target for PRRS, providing insights into possible drug therapies.
期刊介绍：
Biochemical Genetics welcomes original manuscripts that address and test clear scientific hypotheses, are directed to a broad scientific audience, and clearly contribute to the advancement of the field through the use of sound sampling or experimental design, reliable analytical methodologies and robust statistical analyses.
Although studies focusing on particular regions and target organisms are welcome, it is not the journal’s goal to publish essentially descriptive studies that provide results with narrow applicability, or are based on very small samples or pseudoreplication.
Rather, Biochemical Genetics welcomes review articles that go beyond summarizing previous publications and create added value through the systematic analysis and critique of the current state of knowledge or by conducting meta-analyses.
Methodological articles are also within the scope of Biological Genetics, particularly when new laboratory techniques or computational approaches are fully described and thoroughly compared with the existing benchmark methods.
Biochemical Genetics welcomes articles on the following topics: Genomics; Proteomics; Population genetics; Phylogenetics; Metagenomics; Microbial genetics; Genetics and evolution of wild and cultivated plants; Animal genetics and evolution; Human genetics and evolution; Genetic disorders; Genetic markers of diseases; Gene technology and therapy; Experimental and analytical methods; Statistical and computational methods.
