Replacing fish oil with palm oil: Effects onmRNAexpression of fatty acid transport genes and signalling factors related to lipid metabolism in Nile tilapia (Oreochromis niloticus)

This study evaluated the effects of replacing fish oil (FO) with palm oil (PO) on enzyme activities and mRNA expression of lipid transport genes and signalling factors in juvenile Nile tilapia. Nile tilapia (9.34 ± 0.14 g) was fed five experimental diets with FO supplemented with PO at 0%, 25%, 50%, 75% and 100%. Liver was sampled from five fish per tank for analysis of fatty acids, enzyme activities and mRNA expression. Glucose 6-phosphate...
