Project description:A sea bass oligo microarray platform was used to profile gene expression in mandibles of 58 days-old sea bass affected by prognathism, a skeletal malformation that strongly affects sea bass production. Two different conditions: i) protruding jaws, and ii) normal jaws were used for gene expression analysis. For each condition, total RNA was extracted from four (4) independent biological replicates, each consisting of pools of five (5) jaws. Statistical analysis with SAM (Significance Analysis of Microarray) identified 333 probes (corresponding to 242 unique transcripts) significantly down-regulated in deformed individuals compared to normal ones.
Project description:A sea bass oligo microarray platform was used to profile gene expression in whole heads of 38 days-old sea bass affected by prognathism, a skeletal malformation that strongly affects sea bass production. Two different conditions: i) prognathous individuals, and ii) normal individuals were analyzed. For each condition, total RNA was extracted from three (3) independent biological replicates, each consisting of pools of five (5) heads. Statistical analysis with SAM (Significance Analysis of Microarray) didn’t identify any difference in expression patterns between the two groups. Samples were then employed as biological replicates to determine array-to-array reproducibility, the degree of mutual agreement among replicates was estimated using Pearson correlation coefficients on the entire set of expression values. For all pairs of experiments correlation coefficients were always significant (p-value <0.01) and never less than 0.99.
Project description:We identified cis-regulatory elements based on their dynamic chromatin accessibility during the gastrula-larva stages of sea urchin and sea star and studied their evolution in these echinoderm species
