title: GSM4669478: Het_Sample_3; Rattus norvegicus; RNA-Seq
library_construction_protocol: Holtzman Sprague-Dawley rats were housed in an environmentally controlled facility at the University of Kansas Medical Center (KUMC) with lights on from 0600 to 2000 h and allowed free access to food and water. Female rats (8-10 weeks of age) were mated with adult male rats (>3 months of age).  Mating was assessed by inspection of vaginal lavages. ­The presence of sperm in the vagina was designated gd 0.5. Placentation sites were dissected on gestation day 12.5 and placental discs were isolated. Dissected placental disc tissues were snap-frozen in liquid nitrogen and stored at -80°C until processing for RNA isolation. Total RNA was isolated from tissues using TRIzol reagent (Thermo Fisher Scientific, catalog No. 15596018). All rats were maintained in accordance with institutional policies for the care and use of vertebrate animals in research using protocols approved by the KUMC Animal Care and Use Committee. Total RNA was isolated from cells and tissues using TRIzol reagent (cat no. 15596018, Thermo Fisher, Waltham, MA). Complementary DNA libraries from total RNA samples were prepared with Illumina TruSeq RNA preparation kits (Illumina, San Diego, CA). Barcoded cDNA libraries were multiplexed and sequenced with a HiSeq2000 DNA sequencer (100-bp paired-end reads) using a TruSeq 200-cycle SBS kit (Illumina) at the KUMC Genome Sequencing Facility. Reads from *.fastq files were mapped to the rat reference genome (Ensembl Rnor_5.0.78) using CLC Genomics Workbench 12.0 (Qiagen, Redwood City, CA). mRNA abundance was expressed in reads per kb of exon per million reads mapped.  A false discovery rate of 0.05 was used as a cutoff for significant differential expression (euglycemia vs hyperglycemia).
