Description
In the present study, transcript profiling was carried out in the liver samples from wk 5 of lactation in order to identify genes and pathways regulated by rumen-protected CLA during early lactation. The first wks after parturition represent a critical phase in the productive cycle of high-yielding dairy cows because the liver experiences pronounced metabolic and inflammatory stress which increases the risk to develop liver-associated diseases, such as fatty liver and ketosis.

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
Background: While the mechanisms underlying the lactation-induced adaptations of intermediary metabolism and immune response have been extensively studied in rodents and dairy cows, little is known in this regard in sows. Therefore, the present study aimed to explore the lactation-induced changes in hepatic gene expression in sows during lactation.

Description
The clinical impact of aberrant CEBPA promoter methylation (PM) in AML is controversial discussed. The aim of this study was to clarify the significance of aberrant CEBPA PM with regard to clinical features in a cohort of 572 de novo AML with wildtype CEBPA and normal karyotype. The distal promoter was methylated in 54/572 cases (9.41%) whereas proximal PM was never detected. Methylation of the core promoter was detected in only 8 of 326 cases (2.45%) and thus seems to be a rare event in AML. There was no correlation between CEBPA distal PM, age, sex, white blood cell (WBC) count or Hb levels at diagnosis. We also were not able to detect a significant correlation between the presence of CEBPA distal PM and molecular mutations such as FLT3-ITD, NPM1, AML1, MLL-PTD and IDH1. Solely the frequency of IDH2R140 mutations was significantly reduced in CEBPA distal PM positive compared to CEBPA distal PM negative cases (p=0.01). Furthermore, analysis of CEBPA mRNA expression level revealed no difference between CEBPA distal PM positive and CEBPA distal PM negative cases, suggesting that CEBPA distal PM has no influence on CEBPA expression. CEBPA distal PM did not show impact on overall survival (OS), event free survival (EFS) or incidence of relapse. Also when other mutations were taken into regard no prognostic impact of CEBPA distal PM could be shown. In contrast, a distinct expression profile of CEBPA distal PM positive cases compared to CEBPA mutated and CEBPA distal PM negative cases was observed. In addition, a significantly higher frequency of CEBPA distal PM was detected in RUNX1-RUNX1T1 positive AML compared to the CEBPA witdtype cases. We conclude that the presence of aberrant CEBPA PM has no clinical relevance and is therefore a negligible prognostic marker in de novo AML with normal karyotype.

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
Abnormal function of genes is at the root of most cancers, but heritable cancer syndromes account for a very small minority of all tumors in humans and domestic animals. The majority of cancers are sporadic, that is, they are not heritable in the strictest sense. Instead, sporadic cancers occur due to interactions of unknown intrinsic (heritable) and environmental factors that lead to malignant transformation and uncontrolled growth. Identification of heritable risk factors in sporadic human cancers is difficult because individual genetic backgrounds are very heterogeneous. To this end, individual genetic backgrounds of purebred dogs are more homogeneous, and dog breeds show different predilection to develop specific cancers. Here, we used genomic screens based on gene expression profiling to identify sets of genes that may contribute to the development of canine hemangiosarcoma, a relatively common endothelial sarcoma. Specific genes in a single breed (Golden Retrievers) are modulated by (or with) heritable risk traits, showing functional features that appear to modulate tumor behavior. Our results suggest these methods are suitable to identify genes that will enhance our understanding of how these cancers happen, as well as possible treatment targets that will improve outcomes of both human and canine cancer patients.

Description
Acute myeloid leukemia (AML) with CEBPA mutations is determined as provisional entity in the current WHO. A difference in clinical outcome between single- (sm) and double-mutated (dm) cases has been reported, whereupon dm cases were shown to be associated with longer overall survival (OS). The occurrence and prognostic impact of concomitant molecular mutations in addition to CEBPAdm has not been assessed until now. Here, we investigated a cohort of 95 AML CEBPAdm cases for concomitant mutations. TET2 was found to be the most frequent mutation (32/94, 34.0%), followed by GATA2 (20/95, 21.0%), WT1 (13/95, 13.7%), DNMT3A (9/94, 9.6%), ASXL1 (9/95, 9.5%), NRAS (8/95, 8.4%), KRAS (3/94, 3.2%), IDH1/2 (6/95, 6.3%), FLT3-ITD (6/95, 6.3%), FLT3-TKD (2/95, 2.1%), NPM1 (2/95, 2.1%), and RUNX1 (1/94). No mutation was detected in MLL-PTD and TP53. With respect to prognostic impact, we observed that those cases harboring additional mutations in TET2 showed significant worse survival than wild-type cases (P=0.035), whereas GATA2 mutated cases showed improved survival (P=0.032). Further, using gene expression microarray analysis we identified no clear different clustering within the CEBPAdm cases with the distinct concomitant mutated genes. In conclusion, we demonstrated that 76.8% of CEBPAdm cases harbored additional alterations in other molecular markers and that CEBPA is a suitable MRD marker to control therapy.
