ABSTRACT
Stress affects health thereby its production in aquaculture, and fish are simultaneously
exposed to multiple stresses. Here, we performed network-based gene clustering to characterize
regulatory gene networks and metabolic pathways which unveil the relationships between
multiple abiotic stress responsive genes.To analyze multiple responses, we performed
metaanalysis and identified 1214 genes were upregulated, and 670 genes were down-regulated in
zebrafish.The database for annotation, visualization, and integrated discovery was employed for
functional analysis of the differentially expressed genes, PPI modules and WGCNA coexpression
modules. WGCNA identified 12 modules enriched significantly in multiple stress
response.These modules are enriched for genes involved in controlling the immune response,
endocrine response, carbohydrate metabolism, antioxidant response, stimulus response,
homeostasis,and apoptosis. These results extend our knowledge of the multiple stress responses
of fish at the molecular level and indicate that fish have evolved common mechanisms to cope
with multiple stresses.
