(Submitter supplied) Hybridization of one kidney of cortisol treated fish vs. one kidney of control fish. Kidneys were collected from untreated juvenile sea bream (n=4) and from fish, which received for 72h a coconut-oil implant containing 10mg/Kg (fish wet weight) (n=4) cortisol. Experiments were carried out at the University of the Algarve, Portugal in accordance with National legislation for the welfare of animals. Experiments were conducted in two 125 l cylindriconical tanks supplied with a continuous through-flow of oxygenated seawater at 20+1 °C using juvenile sea bream (25 g + 3 g) adapted for 1 week to the experimental conditions. One tank contained 8 untreated fish (control) and the other tank 8 cortisol treated fish and the end of experiments fish were removed form tanks, decapitated and the kidneys rapidly removed and place in RNAlater (Qiagen) at –20 °C. No mortality occurred in the control tank but 2 fish died in the cortisol treated tank. Keywords: other

(Submitter supplied) Microarray technology provides a powerful tool for gene discovery studies, but the development of microarrays for individual species can be expensive and time-consuming. In this study, we test the suitability of a Danio rerio oligonucleotide microarray for application in a species with few genomic resources, the coral reef fish Pomacentrus moluccensis. Coral reef fishes are expected to experience rising sea surface temperatures due to climate change. more...

(Submitter supplied) Two different early developmental stages of gilthead sea bream: i) larvae at 24 hours post-hatching ( Stage 1), and ii) larvae at 96 hours post-hatching (Stage 4), were used for gene expression analysis. For each stage, total RNA was extracted from five (5) independent biological replicates, each consisting of pools of approximately 40-50 larvae. Based on SAM analysis, 1518 genes were differentially expressed between the two stages with a FDR (False Discovery Rate) of 0.0.

(Submitter supplied) PURPOSE: Hyperoxia is toxic to photoreceptors, and this toxicity may be important in the progress of retinal dystrophies. This microarray study examines gene expression induced in the C57BL/6J mouse retina by hyperoxia over the 14-day period during which photoreceptors first resist, then succumb to, hyperoxia. METHODS: Young adult C57BL/6J mice were exposed to hyperoxia (75% oxygen) for up to 14 days. more...

(Submitter supplied) In Sparus aurata, seasonal temperature variations outside the normal thermal range, may trigger physiological responses leading to pathologies and death. In the present study two groups of wild sea bream were exposed for 21 days to two temperature regimes: 16 ± 0.3 °C (control group) and 6.8 ± 0.3 °C (cold-exposed group). Samples were collected during the acute phase (0, 6 and 24 hours after temperature drop) and upon chronic exposure (21 days).

(Submitter supplied) The potential of an hepatic transcriptome expression profile, evaluated in a sentinel feral fish, to serve as an environmental biomarker was examined. Gene expression profiles of individuals of Lithognathus mormyrus were examined using a cDNA microarray and were correlated to the set of environmental exposure conditions at their site and date of collection. The clusters of individual gene expression profiles were reasonably related to the fish samples and several sample-specific clusters of genes, designated gene signatures of the sample, were determined. more...
