Project description:In this study, we applied high-throughput sequencing technology to examine miRNAs in Japanese flounder (Paralichthys olivaceus) infected with Streptococcus iniae at different times.
Project description:Many known miRNAs in fish come from zebrafish and fugu whose genome sequence data are available. The Japanese flounder undergoes typical metamorphosis which is characterized by major morphological, functional, and behavioral changes during growth due to this metamorphosis from larva to juvenile. Metamorphosis is a biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation. Here, the high-throughput sequencing was adopted to identify the miRNAs during metamorphosis in the Japanese flounder. We found abundant microRNAs during metamorphosis in the Japanese flounder. Small RNAs were sequenced from metamorphosis stages of Japanese flounder

Project description:The 987 probes (Japanese flounder conserved miRNAs and candidates, fish conserved miRNAs, and contro) were hybridized with two stages during Japanese flounder metamorphosis by miRNA microarray. We validated 92 miRNAs using miRNA microarray in the 17 dph and 29 dph of Japanese flounder development, and obtained 66 differertially expressed miRNAs by comparison miRNA expression patterns of the two stages. These results indicate that miRNAs might play key roles in regulating gene expression during Japanese flounder metamorphosis.

Meanwhile, 66 conserved miRNAs were differertially expressed by comparison miRNA expression patterns of the two stages. We further identified flounder miRNAs during metamorphosis.
Project description:Gene expression profiles by microarray have contributed for a elucidation of an immune-response and a determination of efficiency in vaccination. Recent day, edwardsielosis have caused a fatal damage in the aquaculture of Japanese flounder, Paralichthys olivaceus. However the formalin killed-cell vaccines made from Edwardsiella tarda isolated same fish species were not efficient. Recent our study revealed the mixed FKC vaccine made from the two different type of E. tarda protected Japanese flounder against Edwardsiella tarda infection for long-term. In this study, we analyzed the immune-response of a vaccinated fish kidney using the mixed FKC vaccine against Edwardsiella tarda with an Agilent custom-oligo DNA microarray on 9,573 probes of Japanese flounder. Our study revealed that the mixed FKC vaccine confered a strong immune-response and keeped a efficient for long-term on Japanese flounder.
