The skin transcriptome analysis of yellow catfish (Tachysurus fulvidraco? × P. vachellii?) under transport stress

The skin transcriptomes were examined by high-throughput sequencing at control group and 16 h transport group. A total of 1577 genes were differentially expressed, including 892 up-regulated and 685 down-regulated. It is interesting to note that the qPCR analysis further confirmed that the skin's immune response to transport stress was activated via Toll-like receptors (TLRs) and NOD-like receptors (NLRs) in skin: the tlr9, mfn2 and ikbke were significantly up-regulated and nfkbia, map3k7cl were significantly down-regulated. Overall results suggested that transport stress. The overall results suggest that the skin responds to transport stress by regulating mucus secretion and activating the immune signal pathway. This study will help to optimize the transport conditions for cultured hybrid yellow catfish. Overall design: The skin transcriptomes were examined at control group and 16 h transport group.
