Immunomodulatory Effects of SPHK1 and Its Interaction with TFAP2A in Yellow Drum (Nibea albiflora).

ABSTRACT: Sphingosine kinases (SPHKs) are essential enzymes that catalyze the phosphorylation of sphingosine to produce sphingosine-1-phosphate (S1P), which plays pivotal roles in inflammation and immune regulation. In this study, genome-wide association analysis (GWAS) identified the Ydsphk1 gene as closely associated with the resistance of yellow drum (Nibea albiflora) to Vibrio harveyi. Structural prediction showed that YDSPHK1 contains a typical diacylglycerol kinase catalytic (DAGKc) domain (154-291 aa). By constructing and transfecting Ydsphk1 expression plasmids into yellow drum kidney cells, we found that YDSPHK1 is localized in the cytoplasm. Subsequent RNA-Seq analysis of an overexpression plasmid identified 25 differentially expressed genes (DEGs), including 13
