In the present study, the transcriptomic profiles of the head
kidneys from FC-infected and non-infected Mandarin fish were
obtained and compared using ultrahigh-throughput sequencing
techniques and several databases. There were 1019 genes
expressed differently between the two groups, including 603 upregulated
genes and 416 down-regulated genes. Since the samples
were from head-kidney which is the key immune organ of
Mandarin fish, and we were more interested in the genes involved
in immune responses, 27 immune related genes which were
differently expressed in the FC-infected and non-infected groups
were found, including 17 up-regulated and 10 down-regulated
genes which are discussed below.
