Figure 9. Correlations between gene expressions in spleen.

Pearson correlation coefficient procedure was used to establish relationships between gene expression of nuclear receptors PPARγ, NF-κB and signalling p38-MAPK, inflammation-related molecules and antioxidant defense enzymes in spleen of pigs received dietary camelina cakes. The red and green colour gradient from dark to light shows the degree of positive or negative correlations respectively in spleen of pigs treated or not with camelina diet.
