Lycopene effects on body weight, plasma TG, and hepatic steatosis in DIO-zebrafish. (A) Average body weight in each group during 4-week feeding experiments. Values are mean ± SD. Each group contained 20 samples. *P < 0.05; **P < 0.01 vs. vehicle with overfeeding, black circles. (B) Change of plasma TG levels in each group. *P < 0.05 vs. vehicle with overfeeding. (C) Oil red O staining of liver sections.
