The inflammatory response to infections, such as bacteria and viruses is mediated by multiple host factors. The tumor related-genes are the important cytokines in mammals. However, a number of tumor related-genes are not identified in the rock bream. Here, we have reported the identification and molecular characterization of the tumor related genes. The LPS-induced TNF-α factor 1 and 2 (LITAF1, LITAF2), tumor necrosis factor superfamily member 14 (TNFSF14), tumor necrosis factor receptor superfamily member 14 (TNFRSF14) and translationally controlled tumor protein (TCTP), programmed cell death 10 (PCD10) from rock bream are used for the under investigations. The LITAF1 and LITAF2 consist of 138 and 163 amino acids with a conserved LITAF domain. TNFSF14 and TNFRSF14 comprise 266 and 181 amino acid, respectively. TCTP encompasses of 170 amino acid containing two conserved TCTP signatures. Furthermore PCD10 consists of 210 amino acids. Using quantitative real-time PCR, we have obtained expression analysis results of LITAF1 and 2, TNFSF14, TNFRSF14, TCTP, PCD10 in the various tissue. Compared to the control, the tumor related genes mRNA is detected at a high levels in gill (LITAF1, TCTP), intestine (LITAF2), liver (PCD10), spleen (TNFSF14) and RBC (TNFRSF14). We have also performed gene expression analysis in the kidney, spleen, liver and gill after challenging with Streptococcus iniae, Edwardsiella tarda and Red seabream iridovirus. We have acquired the dynamic regulated mRNA expression to each of pathogen according to the tissue. Expression of tumor related-genes mRNA are significantly increased by infected with pathogens in most of the tissue. But oddly, PCD10 mRNA is expressed significantly decreased by S. iniae infection in all of tissues. Our results reveal that rock bream tumor relatived-genes may be involved in rock bream immune responses to pathogen infections, as well as, they also act like potential biomarkers for innate immunity.
