Identification and functional characterization of caspases in turbot (Scophthalmus maximus) in response to bacterial infection

Apoptosis is the autonomous and orderly death of cells under genetic control to maintain the stability of the internal environment, and is a programmed cell death process with unique morphological and biochemical properties that is regulated by a variety of factors. Caspase gene family has a significant function in the process of apoptosis. However, the knowledge of caspases in turbot remains largely unknown. In present study, a total of nine turbot caspase genes were identified. The mRNA length of these caspase genes was ranged from 1225 bp (caspase-7) to 3216 bp (caspase-2), and the protein length was ranged from 281 aa (caspase-3a) to 507 aa (caspase-10). Phylogenetic analysis showed these caspase genes were divided into three subfamilies. The qRT-PCR results showed that turbot caspase genes were expressed in all the examined organs, especially the intestine, kidney, blood and gills. Meanwhile, we explored the expression patterns of caspase genes in the intestine, skin and gills after Vibrio anguillarum and Aeromonas salmonids infections. The results showed that caspase genes showed different expression patterns in mucosal tissues after bacterial infection, demonstrating the critical role of caspase genes in mucosal immune responses. In addition, protein-protein interaction analysis showed that caspase proteins interacted with immune molecules such as NLR, IL-1β, and birc. The results of interference and overexpression experiments showed that caspase-1 might play key roles in the regulation of the IL-1β production, but the detailed mechanism needs to be further studied. The results of this study provide valuable information for further study the roles of caspase genes in turbot, which could help us to further understand the inflammatory pathways in teleost.
