Histone H3K27 acetylation mediated by KAT8 maintains antiviral immunity in shrimp trained with inactivated WSSV

Project description:The phenomenon of trained immunity, which facilitates vaccine development for disease control, has been identified in shrimp; however, the mechanism remains elusive. In the present study, we found that histone H3K27 acetylation (H3K27ac) mediated by the lysine acetyltransferase KAT8 plays an important role in preventing white spot syndrome virus (WSSV) infection in the shrimp Marsupenaeus japonicus. We then successfully established a model of trained immunity via the use of UV-inactivated WSSV to explore the underlying mechanism(s) in shrimp. In UV-WSSV-trained shrimp, the glycolysis and tricarboxylic acid (TCA) cycle metabolic pathways were enhanced and acetyl-CoA concentrations were increased. As the acetyl group donor, acetyl-CoA promotes KAT8 activity to increase H3K27 acetylation. H3K27ac is deposited at the promoter region of the transcription factor Dorsal to facilitate its expression and then Dorsal promotes the expression of an interferon-like cytokine, Vago5, and antimicrobial peptides that act against WSSV infection. H3K27ac is also deposited at the promoter region of hexokinase 2 and isocitrate dehydrogenase, which positively regulates glycolysis and the TCA cycle in a feedforward manner. Our results reveal a novel mechanism of trained immunity induced by UV-WSSV in shrimp and provide a theoretical basis for the development of antiviral vaccines for disease control in shrimp aquaculture.

Identification of differentially expressed genes against WSSV infection in Penaeus monodon by microarray

Project description:Microarray analysis of the gill tissues of WSSV infected shrimp (P. monodon) at different time intervals 6 hrs, 24 hrs, 48 hrs and moribund stage of post WSSV infection was carried out to identify differentially expressed genes in response to WSSV infection. The shrimps in WSSV challenege experiment were challenged through intra muscular route with known concentration of virus. The important immune genes identified would be further characterized by sequence analysis and gene expression profile would be validated by real time PCR One-color experiment,Organism: Penaeus monodon, Custom Penaeus monodon (Black Tiger Shrimp) 8x60k designed by Genotypic Technology Private Limited (AMADID: 041733), Labeling kit: Agilent Quick-Amp labeling Kit (p/n5190-0442)

Stress induced gene expression profiling in Penaeus monodon

Project description:Cultured shrimp are continuously exposed to variable environmental conditions which are associated with stress and subsequent outbreaks of disease. To investigate the effect of environmental stress on Penaeus monodon gene expression, a 3853 random cDNA microarray chip was generated with clones originating from 6 stress-enriched hemocyte libraries generated by suppression subtractive hybridization and a normal hemocyte cDNA library. Changes in temporal gene expression were analyzed from shrimp exposed to hypoxic, hyperthermic and hypoosmotic conditions. 3.1% of the cDNAs were differentially expressed in response to at least one of the environmental stressors. 70% of the differentially expressed clones had no significant sequence similarity to previously known genes. Among those genes with high identity to known sequences, the most common functional groups were immune related genes and non-LTR retrotransposons. Hierarchical clustering revealed a set of cDNAs with temporal and stressspecific gene expression profiles as well as a set of cDNAs indicating a common stress response between stressors. Hypoxic and hyperthermic stressors induced the most severe short-term response in terms of gene regulation, and the osmotic stress had the least variation in expression profiles relative to the control. These expression data agree with observed differences in shrimp physical appearance and behavior following exposure to stress conditions. Keywords: stress response, shrimp, time series
