Description
As polyphenols are exerting a broad spectrum of metabolic effects, we hypothesize that feeding of GSGME might influence other metabolic pathways in the liver which could account for the positive effects of GSGME observed in cows during early lactation. In order to investigate this hypothesis, we used using a genome-wide transcript profiling technique to explore changes in the hepatic transcriptome of cows supplemented with GSGME during the transition period. Transcriptomic analysis of the liver revealed 207 differentially expressed transcripts (fold change > 1.3 or < -1.3, P < 0.05), from which 156 (155 mRNAs, 1 miRNA) were up- and 51 (43 mRNAs, 8 miRNAs) were down-regulated, between cows fed GSGME and control cows. Gene set enrichment analysis of the 155 up-regulated mRNAs showed that the most enriched gene ontology (GO) biological process terms were dealing with cell cycle regulation, such as M phase, cell cycle phase, mitotic cell phase and microtubule cytoskeleton and the most enriched KEGG database pathways were p53 signaling and cell cycle. Functional analysis of the 43 down-regulated mRNAs revealed that 13 genes (XBP1, HSPA5, HERPUD1, DNAJC5G, CALR, PDIA4, DNAJB11, PHLDA1, PPP1R3C, GADD45B, BAG3, HYOU1, MANF) are involved in ER stress-induced UPR. Moreover, several of the down-regulated mRNAs, like CXCL14 and CCL3L1L and the acute phase protein SAA4, play an important role in inflammatory processes. Accordingly, protein folding, response to unfolded protein, response to protein stimulus, unfolded protein binding, chemokine activity, chemokine receptor binding and heat shock protein binding were identified as one of the most enriched GO biological process and molecular function terms assigned to the down-regulated genes. In line with the transcriptomics data the plasma concentrations of the acute phase proteins SAA and haptoglobin were reduced in cows fed GSGME compared to control cows. Collectively, our findings from transcriptome analysis of down-regulated mRNAs and functional analysis of mRNAs targeted by the up-regulated mir-376c clearly indicate that GSGME is able to inhibit inflammatory processes and ER stress in the liver of dairy cows during early lactation. Moreover, our findings indicate that at least some of the GSGME effects on the hepatic transcriptome of dairy cows are mediated by miRNA-mRNA interactions.

Description
The hypothesis was tested that insect meal (IM) as protein source influences intermediary metabolism of growing pigs. To test this, 5-week-old crossbreed pigs were randomly assigned to 3 groups of 10 pigs each with similar body weights (BW) and fed isonitrogenous diets either without (CON) or with 5 % IM (IM5) or 10 % IM (IM10) from Tenebrio molitor L. for 4 weeks and skeletal muscle was analyzed using transcriptomics. Transcriptomics of skeletal muscle revealed a total of 198 transcripts differentially expressed between IM10 and CON.

Description
Bipolar disorder (BPD) is a debilitating heritable psychiatric disorder. Contemporary models for the manic pole of BPD have primarily utilized either single locus transgenics or treatment with psychostimulants. Our lab recently characterized a mouse strain, termed Madison (MSN), which naturally displays a manic phenotype, exhibiting elevated locomotor activity, increased sexual behavior, and higher forced swimming relative to control strains. Lithium chloride and olanzapine treatments attenuate this phenotype. In this study, we replicated our locomotor activity experiment, showing that MSN mice display generationally-stable mania relative to their outbred ancestral strain, hsd:ICR (ICR). We then performed a gene expression microarray experiment to compare hippocampus of MSN and ICR mice. We found dysregulation of multiple transcripts whose human orthologs are associated with BPD and other psychiatric disorders including schizophrenia and ADHD, including: Epor, Smarca4, Cmklr1, Cat, Tac1, Npsr1, Fhit, and P2rx7. RT-qPCR confirmed dysregulation for all of seven transcripts tested. Using a network analysis, we found dysregulation of a gene system related to chromatin packaging, a result convergent with recent human findings on BPD. Using a novel genomic enrichment algorithm, we found enrichment in genome regions homologous to human loci implicated in BPD in replicated linkage studies including homologs of human cytobands 1p36, 3p14, 3q29, 6p21-22, 12q24, 16q24, and 17q25. Our findings suggest that MSN mice represent a polygenic model for the manic pole of BPD showing much of the genetic systems complexity of the corresponding human disorder. Further, the high degree of convergence between our findings and the human literature on BPD brings up novel questions about evolution by analogy in mammalian genomes.

Description
The complex milieu of inflammatory mediators associated with many diseases is often too dilute to directly measure in the periphery, necessitating development of more sensitive measurements suitable for mechanistic studies, earlier diagnosis, guiding selection of therapy, and monitoring interventions. Previously, we determined that plasma of recent-onset (RO) Type 1 diabetes (T1D) patients induce a proinflammatory transcriptional signature in fresh peripheral blood mononuclear cells (PBMC) relative to that of unrelated healthy controls (HC). Here, using an optimized cryopreserved PBMC-based protocol, we analyzed larger RO T1D and HC cohorts. In addition, we examined T1D progression by looking at longitudinal, pre-onset and longstanding T1D samples.
