Description
Epiblast stem cells (EpiSCs) were derived from the epiblast or the ectoderm (epi/ect) of pre-gastrula stage to late-bud stage mouse embryos. To identify if the EpiSCs retain any original stage specific characteristics or which developmental stage of epi/ect they most closely related to, we performed microarray analysis to compare the gene expression profile of multiple EpiSC lines with that of epi/ect of 7 different stages.
Publication Title
The transcriptional and functional properties of mouse epiblast stem cells resemble the anterior primitive streak.

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.

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.
Publication Title
White blood cell differentials enrich whole blood expression data in the context of acute cardiac allograft rejection.

Description
B6D2F1 male mice at the age of 6 weeks were maintained for one week in a 12h light / 12 h dark (LD12:12) cycle (lights on from 7:00 am to 7:00 pm) and food and water ad libitum. Mice were then divided in two experimental groups which were further maintained for 3 weeks in the LD12 cycle and fed either at libitum or only during a 4 h period between 9:00 am and 1:00 pm. All animals were then implanted subcutaneously with a pancreatic P03 adenocarcinoma in both flanks. Tumour growth was monitored daily and twenty one days after innoculation, animals were transfered to constant darkness for 24h. Tumour samples were collected at the implantation site at circadian time (CT)4 and CT16.

Description
Changes in Treg function are difficult to quantify due to the lack of Treg-exclusive markers in humans and the complexity of functional experiments. We sorted naive and memory human Tregs and conventional T cells, and identified genes that identify human Tregs regardless of their state of activation. We developed this Treg signature using Affymetrix human genome U133A 2.0 microarrays.
