Project description:Archived skin samples collected during common bottlenose dolphin health assessments in Barataria Bay, LA from 2016 to 2017 were analyzed by RNA-seq to support and enhance the assessment of animal health. The transcriptomic data were analyzed in conjunction with the substantial pool of health and environmental data collected during health assessments to investigate the utility of transcriptomic data in overall assessment of dolphin health and/or as markers of specific health concerns.

Project description:Goal: To determine the effects of capture-release events in wild dolphins (Tursiops truncatus). Methods: An analysis of the Peripheral Blood Leukocyte (PBL) transcriptome was conducted on a group of 20 animals. The samples were collected in 2 different locations along the US east coast (Charleston, SC; Indian River Lagoon, FL) and 2 blood samples were collected for each dolphin 1) immediately after the capture event (*pre*) and 2) just before the animal was released (*post*). In between *pre* and *post* blood collections (30-40 minutes) additional samples were collected from the animals for physiological, chemical and biochemical analysis. RNA extracted from *pre* and *post* blood samples was used for micorarray hybridizations and transcriptome analysis using a species-specific PBL cDNA microarray (Mancia *et al*., 2007).

Project description:We have analyzed the genome-wide patterns of gene expression with DNA microarrays in skin biopsies from 34 subjects: 17 patients with SSc with diffuse scleroderma (dSSc), 7 patients with SSc with limited scleroderma (lSSc), 3 patients with morphea and 6 healthy controls. In total, 61 skin biopsies were analyzed. The addition of 14 technical replicates resulted in a total of 75 microarray hybridizations. The Intrinsic_scleroderma_genes.txt supplementary file lists the 995 genes with the most consistent expression between each forearm-back pair and technical replicates, but with the highest variance across all samples analyzed. An intrinsic gene identifier algorithm was used to select a set of intrinsic scleroderma genes. A total of 34 experimental groups were defined, each representing the 34 different subjects in our study. Replicate hybridizations for a given patient were assigned to the same experimental group. Each gene was analyzed and assigned a score that is inversely related to how intrinsic the gene's expression is across the samples analyzed. The analysis was repeated on randomized data in order to estimate a False Discovery Rate (FDR). An intrinsic score of 0.3 selected 995 genes with an FDR of 4% (39 ± 7 genes) while retaining reproducible clustering of technical replicates.

Project description:Targeted approaches have been widely used to help explain physiological adaptations, but few studies have used non-targeted omics approaches to explore differences between diving marine mammals and terrestrial mammals. A rank comparison of undepleted serum proteins from common bottlenose dolphins (Tursiops truncatus) and pooled normal human serum led to the discovery of 11 proteins that appeared exclusive to dolphin serum. For dolphin proteins that did not match human serum proteins, a second comparison was made with Yorkshire pig (Sus scrofa)serum proteins to determine whether phylogenetic differences in serum proteins could simply explain the differences between dolphin and human. Three out of 11 proteins that were considered unique to the dolphin high abundance serum proteome were ranked within the high abundance pig serum proteome. Compared to the comprehensive human plasma proteome, 5 of 11 serum proteins had a differential rank greater than 200. Major differences exist in the circulating blood proteome of the bottlenose dolphin compared to terrestrial mammals and exploration of these differences in bottlenose dolphins and other marine mammals may identify veiled protective strategies to counter physiological stress.

Project description:A Multiple Affinity Removal System (MARS) Human 14 spin cartridge was used to deplete a dolphin serum which was then digested with trypsin and analyzed without prior fractionation by nanoLC-MS/MS. These files are associated with "2011-9-25_Neely-DolphinSerum." Data analysis: raw data generated by the AB Sciex 5600 were converted to a peak list using the AB Sciex MS Data Converter (v. 1.1 beta, July 2011). Protein identifications were made using Mascot (v. 2.3.02) searching against the Ensembl (release 64) turTru1 dolphin genome assembly protein database [16,598 sequences] and the common Repository of Adventitious Proteins database (cRAP; 2012.01.01; the Global Proteome Machine) using the following parameters: trypsin was selected as the enzyme and three missed cleavages were allowed; carbamidomethylation (Cys) was specified as a fixed modification; glucosylgalactosyl (Lys), oxidation (Met, Pro), and 2-succinyl (Cys) were specified as variable modifications; a precursor tolerance of 10 ppm and fragment ion tolerance of 0.5 Da; instrument type was ESI-QUAD-TOF. Additionally, a non-depleted dolphin sera that had been digested followed by quasi-fractionation using SPE, was analyzed by nano-LC-MS/MS which lead to an additional peptide identification, KGEPGESAYVYR, and these files are associated with "2012-12-12 Dolphin IDA".
