Description
Primitive neuroectodermal tumors of the central nervous system (CNS PNETs) are highly aggressive, poorly differentiated embryonal tumors occurring predominantly in young children. Using DNA methylation and gene expression profiling we have demonstrated that a significant proportion of institutionally diagnosed CNS PNETs display molecular profiles indistinguishable from those of various other well defined CNS tumor entities, facilitating diagnosis and appropiate therapy for children with these tumors. From the remaining fraction of CNS PNETs, we have identified four distinct new CNS tumor entities extending to other neuroepithelial tumors, each associated with a recurrent genetic alteration and particular histopathological and clinical features. These molecular entities, designated CNS Neuroblastoma with FOXR2 activation (CNS NB FOXR2), CNS Ewing sarcoma family tumor with CIC alteration (CNS EFT CIC), CNS high grade neuroepithelial tumor with MN1 alteration (CNS HGNET MN1), and CNS high grade neuroepithelial tumor with BCOR alteration (CNS HGNET BCOR), will enable meaningful clinical trials and the development of therapeutic strategies for patients affected by these poorly differentiated CNS tumors.

Description
The objective of this study was to examine the effect of dietary restriction and subsequent re-alimentation induced compensatory growth on the global gene expression profile of jejunum epithelial Holstein Friesian bulls (n=40) were assigned to one of two groups: restricted feed allowance (RES; n=20) for 125 days (Period 1) followed by ad libitum access to feed for 55 days (Period 2) or (ii) ad libitum access to feed throughout (ADLIB; n=20). All bulls received the same diet of 70% concentrate 30% grass silage through out the experimental trial,with the amount of feed provided different dependent on each treatment group. At the end ofeach period, 10 animals from each treatment group (RES, ADLIB) were slaughtered, and jejunum epithelial collected from all animals. RNA was extracted and jejununal epithelium gene expression was examined using RNAseq technology on all samles collected (end of Period 1: 10 samples each from ADLIB and RES groups; end of Period 2: 10 samples each from ADLIB and RES groups). Dietary restriction and subsequent re-alimentation were associated with altered expression of genes involved in digestion and metabolism, aswell as cellular protection and detoxification in jejunal epithelia. This information may be exploited in genomic breeding programmes to assist selection of cattle with a greater ability to compensate following a period dietary restriction. Overall design: 40 jejunumal epithelium RNA samples were analysed in total. 10 samples were from jejunum epithelium collected at the end of a period of dietary restriction (d 125; Period 1) and 10 samples were from jejunum epithelium collected after 55 days of compensatory growth (d 55 of re-alimentation, Period 2). In addition, RNA was also anlaysed from 10 samples collected from animals fed ad libitum at the end of both Period 1 and Period 2.

Description
The objective of this study was to examine the effect of dietary restriction and subsequent re-alimentation induced compensatory growth on the global gene expression profile of ruminal epithelial papillae. Holstein Friesian bulls (n=38) were assigned to one of two groups: restricted feed allowance (RES; n=19) for 125 days (Period 1) followed by ad libitum access to feed for 55 days (Period 2) or (ii) ad libitum access to feed throughout (ADLIB; n=19). All bulls received the same diet of 70% concentrate 30% grass silage through out the experimental trial,with the amount of feed provided different dependent on each treatment group. At the end of Period 1, 9 animals from each treatment group were slaughtered, with 10 animals from each treatment slaughtered at the end of Period 2. Rumen epithelium was collected from all animals within thirty minutes of slaughter. RNA was extracted and rumen epithelium gene expression was examined using RNAseq technology on all samles collected (end of Period 1: 9 samples each from ADLIB and RES groups; end of Period 2: 10 samples each from ADLIB and RES groups). Genes identified as differentially expressed in response to both dietary restriction and subsequent compensatory growth included those involved in processes such as cellular interactions and transport, protein folding and gene expression, as well as immune response. This information can be exploited in genomic breeding programmes to assist selection of cattle with a greater ability to compensate following a period dietary restriction. Overall design: 38 rumen epithelium RNA samples were analyzed in total. Purebred Holstein Friesian bulls were assigned to one of two feeding treatments (i) restricted feed allowance for 125 days (n=9) followed by ad libitum access to feed for a further 55 days (n=10) or (ii) a control group with ad libitum access to feed through out the 180 days trial (n=19). The first 125 days of the trial were denoted as Period 1, during which treatment groups were fed differentially. The subsequent 55 days, denoted as Period 2 during which all bulls were fed ad libitum. All bulls received the same diet of 70% concentrate 30% grass silage through out the experimental trial, with the amount of feed provided different dependent on each treatment group. Restricted fed animals were fed to grow at 0.6 kg /day during Period 1, with ad libitum animals expected to gain in excess of 1.5 to 2 kg/day.

Description
Acute renal allograft rejection is an important complication in kidney transplantation. Accurate diagnosis of rejection events is necessary for timely response and treatment. We illustrate the usefulness and biological relevance of selected multivariate approaches to detect rejection from genomic and proteomic signals. The data was used to study gene expression changes using whole genome microarray analysis of peripheral blood from subjects with acute rejection (n=20) and non-rejecting controls (n=20) to obtain insight into the molecular and biological causation of acute renal allograft rejection when combined with proteomics (iTRAQ) data for the same patients/time-points.

Renal failure is characterized by important biological changes resulting in profound pleomorphic physiological effects termed uremia, whose molecular causation is not well understood. The data was used to study gene expression changes in uremia using whole genome microarray analysis of peripheral blood from subjects with end-stage renal failure (n=63) and healthy controls (n=20) to obtain insight into the molecular and biological causation of this syndrome.

Description
Acute cardiac allograft rejection is a serious complication of heart transplantation. Investigating molecular processes in whole blood via microarrays is a promising avenue of research in transplantation, particularly due to the non-invasive nature of blood sampling. However, whole blood is a complex tissue and the consequent heterogeneity in composition amongst samples is ignored in traditional microarray analysis. This complicates the biological interpretation of microarray data. Here we have applied a statistical deconvolution approach, cell-specific significance analysis of microarrays (csSAM), to whole blood samples from subjects either undergoing acute heart allograft rejection (AR) or not (NR). We identified eight differentially expressed probe-sets significantly correlated to monocytes (mapping to 6 genes, all down-regulated in ARs versus NRs) at a false discovery rate (FDR) <= 15%. None of the genes identified are present in a biomarker panel of acute heart rejection previously published by our group and discovered in the same data.

Description
Pioneering studies within the last few years have allowed the in vitro expansion of tissue-specific adult stem cells from a variety of endoderm-derived organs, including the stomach, small intestine and colon. Here we derived organoids from mouse gallbladder tissue (gallbladder organoids), from mouse liver (including the extrahepatic biliary ducts and gallbladder; liver organoids) and from mouse small intestine tissue (intestinal organoids). RNA was prepared from these organoids and used to assay expression of 21,258 genes using Affymetrix gene expression arrays. RNA was also prepared from mouse gallbladder, liver and small intestine tissues and used to assay gene expression in these tissues. Finally, gallbladder organoids were induced to differentiate by removing R-spondin 1 and noggin from the culture media and subjected to gene expression array analysis.
