Vliv účinných složek rybího tuku v krmné dávce prasat na expresi vybraných proteinů modulujících zánětlivou reakci

The aim of this study was to determine whether there is an influence of the active components of the fish oil, in particular polyunsaturated fatty acids n3 (PUFA n3) on expression of selected proteins which modulate the inflammatory response in model organisms pig. In the n3 PUFA is to assume that over signaling pathway PPARgamma, NFkappaB, increase adiponectin production, inhibit the production of proinflammatory cytokines, increase antiinflammatory cytokines production, thereby suppressing the inflammatory response in the body. This hypothesis was tested on 32 pigs, which were divided into two groups of 16 pieces in each group. The first experimental group was fed the basic feed mixture enriched with 2.5% fish oil (F) and the second control group was fed the basic feed with 2.5% palm oil (P). Last day of fattening pigs were 8 F and 8 P pigs intravenously application lipopolysaccharide (LPS) to induce an inflammatory response, the rest of group left without LPS stimulation, followed by intramuscular application of anesthetics and defeat. By Western blot was measured protein expression PPARgamma and NFkappaB in selected tissues, by ELISA concentration of adiponectin in plasma and by multiplex analysis plasma levels of cytokines. The results indicate that PPARgamma concentration in the F adipocytes after LPS stimulation tended to increase by 21% in comparison with P control stimulation with LPS, but the result was not statistically significant (P> 0.05; P = 0.11). Further, the F pigs stimulation with LPS as compared with intact F counterparts trend toward increased plasma levels of adiponectin by 18%, which was likely a reflection of the tendency to higher values in adipocytes by 18% (P> 0.05, p = 0.12), result was not statistically significant. Plasma adiponectin took on the same values of 21.1 ng x mL-1 in experimental and control groups (P> 0.05). Elevation (P <0.05) of NFkappaB in fatty tissue F pigs after LPS stimulation. In addition, the plasma level of anti-inflammatory IL4 and IL10 interleukins, as well as the proinflammatory cytokine TNFalfa, was increased (P
