Safflower Promotes the Immune Functions of the Common Carp (Cyprinus carpio L.) by Producing the Short-Chain Fatty Acids and Regulating the Intestinal Microflora

Figure 3

Relative mRNA expression levels of tight binding proteins in the midgut of common carp-fed diets with different safflower contents: (a) Claudin; (b) Occludin; (c) NF-κB. Values are given as the (). The mRNA expression level values were normalized to those of 18S and are expressed as a ratio with the control. Different superscript letters in the values showed significant difference (), and the same or unmarked letters showed no significant difference ().
