Key differentially expressed genes in the gill and skin between fasted and fed channel catfish in different functional classifications.

Positive/negative values indicate upregulation and downregulation, respectively, in fasted fish relative to the fed control. When reads number equaled to 0 in fed or fasted group, the fold change is presented by average normalized read number in fed/average normalized read number in fasted. All fold changes were significant at p-value <0.05.
