Abstract
Coilin is a protein localized in the nucleus, where it plays a role in the assembly of the Cajal Body and is involved in ribonucleoprotein biogenesis. Our recent research has uncovered new roles for coilin, including its involvement in producing microRNAs and in modifying other proteins through phosphorylation and SUMOylation. We also proposed that coilin could respond to stress signals. In plants, coilin has been shown to help regulate immune genes and activate defense mechanisms, especially in response to stress. In this study, we used two vertebrate models to study coilin function: a human primary foreskin fibroblast cell line deficient in coilin through RNA interference and a newly created zebrafish line with a mutation in the coilin gene generated by CRISPR-Cas9. Transcriptomic analysis in these two models of coilin deficiency revealed dysregulation of immunity-related genes in both species. To phenotypically validate the transcriptomic results, we challenged zebrafish coilin mutants with lipopolysaccharide (LPS), which triggers an innate immune response, and identified an attenuated response to LPS in vivo in the zebrafish coilin mutants. Our results support a vital novel function for coilin in vertebrates in regulating the expression of immunity-related genes. Moreover, these findings could lead to more research on how coilin regulates innate immunity in animals and humans.
