Effect of three krill lipid fractions on mRNA expression of cytokine (a) TNF-α, (b) IL-1β and (c) IL-6 in RAW264.7 cells with LPS stimulation. Blank group referred to the untreated cells; cells treated with LPS alone were considered as the control group. * p < 0.05 versus the control group; one-way analysis of variance (ANOVA) combined with Duncan’s multiple-range test was used to analyze the significance. Abbreviations: LPS, lipopolysaccharide; KLF-A, the krill lipid fraction extracted with acetone in the first step; KLF-H, the krill lipid fraction extracted with hexane in the second step; KLF-E, the krill lipid fraction extracted with ethanol in the third step.
