(Submitter supplied) Metabolic processes and sexual maturation closely interact during the long-distance reproductive migration of many fish species to their spawning grounds. In the present study, we have for the first time used exercise experimentally to investigate the effects on sexual maturation in rainbow trout. Pubertal autumn-spawning seawater-raised female rainbow trout Oncorhynchus mykiss (n=26; 50-cm, 1.5-kg) were rested or swum at a near optimal speed of 0.75 body-lengths per second in a 6,000 L swim-flume under natural reproductive conditions (16 °C fresh-water, starvation, 8h-light:16h-dark photoperiod). more...

(Submitter supplied) Nylon microarrays displaying 9152 rainbow trout cDNAs were hybridized using RNA samples originating from ovarian tissue collected during late vitellogenesis, post-vitellogenesis and oocyte maturation. Differentially expressed genes were identified using a statistical analysis. A supervised clustering analysis was performed using only differentially expressed genes in order to identify gene clusters exhibiting similar expression profiles. more...

Analysis of fish preovulatory ovaries collected during late vitellogenesis, post-vitellogenesis and oocyte maturation. In fish, the post-vitellogenic period is critical for completion of the oogenetic process. Results provide insight into molecular events occurring during the preovulatory period.

(Submitter supplied) Training at sustainable swimming speeds can produce changes in fish skeletal muscle that are important for aquaculture due to their growth-potentiating effects. Such changes may be even more relevant when fish are fed diets containing an increasing proportion of carbohydrates as an energy source. We evaluated the effects of moderate-intensity sustained swimming on the transcriptomic response of red and white muscle in rainbow trout fed a carbohydrate-rich diet using microarray and qPCR. more...

(Submitter supplied) BACKGROUND: Fast, efficiently growing animals have increased protein synthesis and/or reduced protein degradation relative to slow, inefficiently growing animals. Consequently, minimizing the energetic cost of protein turnover is a strategic goal for enhancing animal growth. Characterization of gene expression profiles associated with protein turnover would allow us to identify genes that could potentially be used as molecular biomarkers to select for germplasm with improved protein accretion. more...

(Submitter supplied) Purpose: mRNA-Seq to reveal the differentially expression pattern of genes in innate/adaptive immune relevant pathways, and combining to the previous DNA microarray analysis to address the immunomodulatory effects of cecropin P1 transgene in rainbow trout. Methods: Total RNA were isolated from three tissues, spleen, liver and kidney, from two individuals of two families of transgenic and one family of non-transgenic fish. more...

(Submitter supplied) Sex steroids play a key role in triggering sec differentiation in fish and the use of exogenous hormone treatment leads to partial or complete sex reversal. This phenomenon has attracted attention since the discovery taht even low environmental doses of exogenous steroids can adversely affect gonad morphology (ovotestis development) and induce reproductive failure. Modern genomic-based technologies have enhanced opportunities to find mechanisms of action (MOA) and dentify biomarkers for the toxic action of a compound. more...

NC1 samples were collected from immature, unexpanded cumulus-oocytes complexes (COC) from prepubertal (3-week-old) mice, C1 samples from immature, unexpanded cumulus-oocytes complexes (COC) from adult (8-week-old) and C2 samples from mature, expanded COCs obtained from the oviduct from 8-week-old mice after standard superovulation protocol.

(Submitter supplied) The rainbow trout, Oncorhynchus mykiss, has a male heterogametic XY genetic system, and this knowledge can be used to produce experimentally all male or all female genetic populations using males with new genotypes (XX and YY males). These monosex populations have been widely used for sex differentiation studies because they give the opportunity to work on undifferentiated gonads for which the natural fate as testis or ovary is known a priori. more...
