Sample GSM2398434 Query DataSets for GSM2398434
Status Public on Nov 14, 2017
Title 72C2_Mass_2
Sample type SRA
 
Source name whole embryo
Organism Sciaenops ocellatus
Characteristics tissue: whole embryo
developmental stage: 72hpf
concentration: 0g/l
Treatment protocol Testing was performed using two different oil types. The first was a naturally weathered oil collected from a slick in the Gulf of Mexico on June 29th, 2010 from the hold of barge number CT02404 (referred to as OFS). The second was a non-weathered source oil MASS recognized as a suitable surrogate for the DWH source oil. Both oils were delivered to the University of Texas Marine Science Institute through proper chain of custody and stored at 4 °C until used. The test was performed in an environmental control chamber set at 25 °C with a 14:10 h light: dark photoperiod. Survival was assessed daily. A minimum of 70% hatching success and 80% subsequent survival was required for the test to be valid.
Growth protocol All experiments were approved by the institutional animal care and use committee (IACUC) at the University of Texas at Austin (AUP-2014-00375). Embryonic red drum (Sciaenops ocellatus) were collected from brood stock tanks at the Texas Parks and Wildlife – CCA Marine Development Center in Corpus Christi, Texas, USA and transported under constant aeration to the University of Texas Marine Science Institute. Embryos were subsequently treated with formalin (1 ppt) for one hour with aeration to remove any bacteria. Spawns with low fertilization rates or poor egg quality were not used.
Extracted molecule total RNA
Extraction protocol Thirty pooled embryos or larvae per replicate were homogenized with a Kontes Pellet Pestle Cordless Motor (Sigma-Aldrich, St. Louis, Missouri) in RNAzol (Molecular Research Center, Cincinnati, Ohio). 200 ng of total RNA was used to prepare RNA-Seq libraries using the TruSeq RNA Sample Prep kit following the protocol described by the manufacturer (Illumina, San Diego, CA).
RNA libraries were prepared for sequencing using standard Illumina protocols
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2500
 
Description 72hrControl
Data processing Illumina Casava1.8 software used for basecalling.
Sequenced reads (fastq files) were trimmed for adaptor sequence, and masked for low-complexity or low-quality sequence
Secondary analysis was carried out on an OnRamp Bioinformatics Genomics Research Platform (OnRamp Bioinformatics, San Diego, CA). OnRamp’s advanced Genomics Analysis Engine utilized an automated RNAseq workflow to process the data, including data validation and quality control and read alignment to the human genome (hg19) using blastx
The resulting SAM files were sorted and inputted into the Python package HTSeq to generate count data for gene-level differential expression analyses.
Transcript count data from DESeq2 analysis of the samples were sorted according to their adjusted p-value or q-value, which is the smallest false discovery rate (FDR) at which a transcript is called significant.
