Effect of chilling on sox2, sox3 and sox19a gene expression in zebrafish (Danio rerio) embryos

► This study focused on the effect of chilling and warming on gene expression. ► No significant differences were observed in the hatching rate following chilling. ► Significant decreases in sox2 and sox3 gene expression were observed following chilling. ► Significant increases in gene expression were found following chilling and warming.
