Fflinks2 [22], specifically Cuffdiff, to generate normalized expression (FPKM) values. The samples from which these mRNA sequences are derived are described above in the section on RNA sequencing and transcript assembly (accessions GenBank:SRX092158, GenBank:SRX092159 and GenBank: SRX101672). We also obtained 60 peripheral blood mononuclear cell (PBMC) samples from rhesus macaques in a social hierarchy experiment performed at the Yerkes National Primate Research Center. We individually subjected 10 macaques that were dominant in the social hierarchy and 10 subordinate macaques to a human intruder as a stressor. Whole blood was then collected at several time points using a BD CPT vacutainer which allow for thecollection of PBMCs. RNA was purified from PBMCs using the RNeasy kit (QIAGEN, Valencia CA). We prepared libraries using standard TruSeq chemistry (Illumina Inc., San Diego CA) and sequenced them PRIMA-1 on an Illumina Hi-Seq 1000 as 2 ?100 base paired-end reads at the Yerkes NHP Genomics Core Laboratory (http:// www.yerkes.emory.edu/nhp_genomics_core/). Sequences were deposited at NCBI under accessions [GenBank: SAMN02743270 - SAMN02743329]. We mapped reads with STAR [33] (version 2.3.0e) to both the rheMac2 and MacaM genomes, using the reference annotations as splice junction references. rheMac2 annotations were obtained from UCSC. We discarded un-annotated noncanonical splice junctions, non-unique mappings and discordant paired-end mappings. We performed transcript assembly, abundance estimates and differential expression analysis with Cufflinks2 (version 2.1.1) and Cuffdiff 2 [22]. We determined differentially expressed transcripts for pair-wise experimental group comparisons with an FDR-corrected p-value (q-value) <0.05. We compared differences in unique read counts and mapping percentages between rheMac2 and MacaM assemblies using a paired T-test.Statement of ethical approvalMaterials used in these studies were from animal work performed under Institutional Animal Care and Use Committee approval from the University of Nebraska Medical Center, Oregon Health and Sciences University and Yerkes National Primate Research Center.
