Project description:Infectious hematopoietic necrosis virus (IHNV) can cause widespread death of rainbow trout (Oncorhynchus mykiss), understanding the molecular mechanisms that occur in the rainbow trout in response to IHNV infection will be useful to decrease IHN-related morbidity and mortality in trout aquaculture. However, the molecular mechanisms of rainbow trout in response to IHNV are very limited. This study performed analysis of mRNAs and miRNAs based on RNA-seq technology on the intestine of rainbow trout infected with IHNV and control. There were 80 differentially expressed miRNAs that regulated 3355 target mRNAs, which overlapped with differentially expressed mRNAs obtained from RNA-seq. The expression patterns of DEGs and miRNAs differentially expressed were validated by qRT-PCR. GO enrichment and KEGG pathway analyses of the potential target genes of the DE miRNAs, revealed DEGs were mainly enriched in immune-related pathways such as Toll-like receptor signaling pathway, RIG-I-like receptor signaling pathway and IL-17 signaling pathway. These findings improve our understanding of the molecular mechanisms of IHNV infection. The study analyzed the immune regulatory target gene pairs and signal pathways of rainbow trout intestine against IHNV infection at the transcriptional level, and provided basic data for the study of rainbow trout against IHNV immune regulatory.

Project description:Gynogenetic development in fish is induced by activation of eggs with irradiated spermatozoa followed by exposure of the activated eggs to the temperature or high hydrostatic pressure (HHP) shock that prevents 1st cell cleavage. Produced specimens are fully homozygous fish also known as Doubled Haploids. Gynogenetic DH individuals might be used aquaculture and developmental biology unfortunately; the potential application of DHs is limited by a rather low survival rate of such specimens. However, observed variation in the survival rates of the gynogenetic embryos originated from different clutches suggests that eggs from some females have increased ability for gynogenetic development than others. Taking into account that first 10 cell cleavages in the fish embryos rely on the maternal RNA, it is tempting to assume that the ova showing such a vast difference in potential for gynogenesis may have also had different biological characteristics including alterations in maternal gene expression profiles. If so, then genes that up- or down –regulated expression in eggs increases competence for gynogenetic development in trout might be considered as candidate genes for gynogenesis in rainbow trout. Thus, the main goal of the project is identification of genes that increase ability of rainbow trout eggs for gynogenetic development. Within the project, we tried to verify following hypotheses: 1. Eggs from different females have different potential for gynogenesis in rainbow trout. 2. Eggs with different ability for gynogenetic development with all maternal inheritance have different biological characteristics including morphology and anti-ROS enzyme activities. 3. Eggs with increased competence for gynogenesis have altered transcriptomic profiles. 4. There are some particular genes that altered expression in trout eggs enable development of gynogenetic embryos. Gynogenetic rainbow trout specimens were produced in the course of activation of eggs with UV-irradiated spermatozoa and High Hydrostatic Pressure shock (HHP) applied around 1st cell cleavage. Eggs from several females were used in the experiment. Survival rates of gynogenetic rainbow trout was monitored since fertilization. Quality of eggs was examined by assessment of their morphology and activity of anti-ROS (reactive oxygene species) enzymes. Transcriptome of eggs showing increased and decreased developmental competence for gynogenesis was analyzed using RNA-seq approach and results compared to find out any alterations related to survival of gynogenetic trout.
