A: the folate content of liver was measured with microbiological assay. The gene expression of slc19a1 (A), slc46a1 (B), folr1 (C), dhfr (D), and mthfr (E) in the intestine was analyzed. Data are presented as means ± SE (n ≥ 5 fish). *P < 0.05; **P < 0.01; ns, no statistical significance. VD, vitamin D.
