In many ant species, sibling larvae follow alternative ontogenetic trajectories that generate striking variation in morphology and behavior among adults. These organism-level outcomes are often determined by environmental rather than genetic factors. Therefore, epigenetic mechanisms may mediate the expression of adult polyphenisms. We produced the first genome-wide maps of chromatin structure in a eusocial insect and found that gene-proximal changes in histone modifications, notably H3K27 acetyl ...[more]

Project description:Genetic association studies, pharmacological investigations and analysis of mice-lacking individual genes have made it clear that Cocaine administration and Withdrawal have a profound impact on multiple neurotransmitter systems. The GABAergic medium spiny neurons of the nucleus accumbens (NAc) exhibit changes in the expression of genes encoding receptors for glutamate and in the signaling pathways triggered by dopamine binding to G-protein-coupled dopamine receptors. Deep sequence analysis provides a sensitive, quantitative and global analysis of the effects of Cocaine on the NAc transcriptome. RNA prepared from the NAc of adult male mice receiving daily injections of Saline or Cocaine, or Cocaine followed by a period of Withdrawal, was used for high-throughput sequence analysis. Changes were validated by quantitative polymerase chain reaction or Western blot. On the basis of pathway analysis, a preponderance of the genes affected by Cocaine and Withdrawal was involved in the cadherin, heterotrimeric G-protein and Wnt signaling pathways. Distinct subsets of cadherins and protocadherins exhibited a sustained increase or decrease in expression. Sustained down-regulation of several heterotrimeric G-protein β- and γ-subunits was observed. In addition to altered expression of receptors for small molecule neurotransmitters, neuropeptides and endocannabinoids, changes in the expression of plasma membrane transporters and vesicular neurotransmitter transporters were also observed. The effects of chronic Cocaine and Withdrawal on the expression of genes essential to cholinergic, glutamatergic, GABAergic, peptidergic and endocannabinoid signaling are as profound as their effects on dopaminergic transmission. Simultaneous targeting of multiple Withdrawal-specific changes in gene expression may facilitate development of new therapeutic approaches that are better able to prevent relapse. High-throughput sequence analysis of RNA prepared from the nucleus accumbens of adult male mice receiving daily injections of Saline or Cocaine, or Cocaine followed by a period of Withdrawal. Nucleus accumbens libraries were sequenced in nine lanes (three technical replicates per sample) on an Illumina GAIIx using a 37-cycle paired-end sequencing protocol. Replicates were analyzed for intra-sample disparity and read data from all three lanes were then merged into one composite data file per sample; intra-sample coefficient of determination, R2 ≥ 0.98. The composite file was used for subsequent analyses.

Project description:Yorkshire pigs were divergently selected for residual feed intake (RFI) for 8 generations. Pigs with low RFI have reduced feed intake. Based on the resource allocation theory, we hypothesize that these low RFI pigs might have compromised immune response to immune stimulation. To test this hypothesis, twenty eight gilts of initial body weight (BW) of 63 4 kg from pigs selected for low RFI and high RFI were randomly selected for the ISU RFI selection project and utilized in two replicates (14 pigs/replicate) for this study. All pigs were housed in individual metabolism pens, had free access to water and were fed a corn-soy-based diet twice daily, and feed restricted (1.5 kg/day) as previously described. After a 9-day adaptation period pigs were randomly assigned within line to either a control (n = 6, three pigs per line) or lipopolysaccharide (LPS) challenge (n = 8, 4 pigs per line) group. Pigs in the challenge group were then repeatedly challenged with an intramuscular injection of 30, 36, 39, and 42 g/kg BW of LPS from E. coli O5:B5 (sigma-Aldrich, St. Louis, MO) dissolved in saline solution at time points 0, 48, 96, and 144 hours post initial injection (hpi) to compensate for LPS tolerance after initial injection, respectively, while animals in the control group were injected with an equivalent volume of saline solution at the equivalent time points. Rectal temperatures of individual pigs were measured immediately before the initial injection (serving as baseline, called 0 hpi for convenience), and 2, 4, 6, and 24 hpi, and 0, 4, 24 hours after each subsequent injection for all pigs. Blood samples were collected from the jugular vein into TempusTM Blood RNA tubes (Life Technologies, Grand Island, NY) for long-term storage at -80 C, EDTA tubes (BD, Franklin Lakes, NJ) for CBC tests and serum tubes for cytokine assays at 0, 2, 6, 24 and 168 hpi. At 168 hpi, all pigs were euthanized via barbiturate overdose, exsanguinated and tissue samples including the longissimus dorsi muscle, liver, spleen, and ileum were isolated, cleaned an frozen for later use. This study only focused on samples and data collected for the first 24 hours. Total RNA was extracted from the 32 blood samples of the treatment group in Replicate 2, collected at 0, 2, 6, and 24 hpi, by using preserved blood RNA purification kit I (Norgen Biotek Corp, Thorold, Ontario) per manufacturers instruction. On-column DNA digestion was performed as described using DNase I (Qiagen, Valencia, CA). Globin transcripts (HBB and HBA) were depleted by following an RNase H-mediated method. The quantity and integrity of the RNA were monitored by using Nanodrop 2000 (Thermo Scientific, Waltham, MA) and Bioanalyzer 2100 (Agilent Technologies, Santa Clara, CA) before and after globin depletion. The efficiency of globin depletion of each sample was checked by conventional RT-qPCR with -actin and GAPDH as the internal controls. Globin depletion efficiencies for all RNA samples were above 85%.

Project description:Purpose: The plant hormone abscisic acid (ABA) coordinates responses leading to desiccation tolerance in all land plants. RNA-seq was employed to obtain differential expression data in response to ABA, dehydration and mannitol treatments in wild-type tissue. This was compared against the targeted gene knockout line PpanrKO. The ANR gene encodes a novel ABA regulator identified from ABA non-responsive (anr) mutant screens. Methods: RNA-seq on the Illumina HiSeq platform and mapping to the V3.0 genome and transcriptome assemblies using tophat2 enabled gene abundance data to be generated for differential gene expression analysis with edgeR in the Trinity package. Results: We observe a coordinated up-regulation of ca. 900 genes, with extensive overlaps between hormone and stress treatments as well as ca. 900 down-regulated genes. Of the up-regulated genes, those encoding LEA proteins, membrane channel proteins and transporters and oxidative-stress-associated genes comprised a significant fraction while those encoding growth-associated cell wall enzymes (e.g. expansins) and components of secondary metabolism (notably enzymes in the phenylpropanoid pathway) were prominent in the down-regulated genes. The ANR gene, a modular MAP3 kinase comprising an N-terminal PAS domain, a central EDR domain and a C-terminal MAPKKK-like domain unique to basal plant lineages, is found to play a central role in these responses with mutants failing to accumulate the wide spectrum of dehydration tolerance-associated gene products characteristic of the wild-type response and do not acquire ABA-dependent desiccation tolerance. Conclusions: Our study adds considerable data to the stress responses in bryophytes helping understand the mechanisms behind vegetative dehydration tolerance; an important trait for crop species. We also confirmed the vital role that PpANR plays in these responses in the moss Physcomitrella patens likely representing an ancestral mechanism for ABA-mediated dehydration tolerance vital in the conquest of land. RNA from 3 biological replicas was bulked per library. 8 libraries were generated from two genotypes, wild-type and PpanrkO, which included 3 treatments and a control sample for each.
