Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
We used microarrays to investigate differential gene expression in HEK293T cells after transfection of the transgene of Iroquois 1 (IRX1). Microarray analysis revealed differential gene expression patterns of HEK293T cells after transient expression of IRX1. In total 8400 genes were deregulated by IRX1.

Description
We generated single-cell RNAseq profiles of 369 microglia (183 from wild type and 186 from Trem2 knock-out), sorted in the gate CD45lowCD11+ or CD45lowCD11+Gpnmb+Clec7a+ (PAM enrichment), to compare gene expression of wild type vs. Trem2 knock-out microglia on the postnatal day 7. Single cells were FACS index sorted from the whole brain followed by Smart-seq2 library preparation and Illumina Nextseq (sequence depth > 1 million per cell). A total of 334 cells passed quality control for data analysis. Microglia in the Trem2 knock-out contained a similar PAM population with characteristic gene expression, suggesting that the presence of early postnatal PAM do not depend on TREM2. Overall design: Single microglia were FACS sorted from male animals (C57BL/6J background) into 96-well plates. Libraries were prepared with a semi-automated Smart-seq2 protocol. Three QC criteria were used (Y=passed, N=not passed), and only cells that passed all three criteria were used for downstream analysis.

Description
We generated single-cell RNAseq profiles of 143 microglia, sorted in the gate CD45lowCD11+Gpnmb+Clec7a+, from postnatal day 7 cerebellum to validate the newly identified “proliferative region-associated microglia (PAM)” (Gpnmb and Clec7a are PAM surface markers). Single cells were FACS index sorted followed by Smart-seq2 library preparation and Illumina Nextseq (sequence depth > 1 million per cell). These cells showed characteristic PAM gene expression and clustered together with other PAM cells sequenced in the same study. Overall design: Single microglia were FACS sorted from pooled male animal samples (C57BL/6N) into 96-well plates. Libraries were prepared with a semi-automated Smart-seq2 protocol. All 143 cells passed the three QC criteria (Y=passed).

Description
To compare microglial regional heterogeneity, we generated bulk RNA-seq profiles of postnatal day 60 microglia, sorted by TMEM119+ (also CD45lowCD11b+), from cortex (CTX), cerebellum (CB), hippocampus (HIP), striatum (STR) regions. For each sample, 3000 microglia were FACS sorted into RLT lysis buffer for total RNA extraction, followed by Smart-seq library preparation and Illumina Nextseq (sequence depth 10-20 million per sample). Consistent with our scRNA-seq data, samples from 4 regions were highly correlated (R>0.99), and individual samples did not cluster according to tissue origins, suggesting striking similarities between homeostatic microglia from different brain regions. Moreover, we could not detect any differentially expressed genes (FDR < 0.05) between regions from the bulk samples. These data suggest that classical adult microglia with homeostatic signatures (e.g. Tmem119), as the most dominant microglial population in the healthy brain, have little transcriptomic heterogeneity across brain regions. Overall design: TMEM119+ microglia (3000 cells each sample) from a given region were FACS sorted from pooled male animal samples (C57BL/6N) into RLT lysis buffer in Eppendorf tubes. Three replicates were done for each region. Libraries were prepared following the Smart-seq protocol (v4 ultra low input RNA kit). All samples were barcoded and pooled together for Illumina Nextseq sequencing.

Description
Aim of this project was the evaluation of the effect of flushing (intraportal and intraoperative) hepatic allografts with tacrolimus before transplantation. Group A was administered tacrolimus, 20ng/ml in 1500ml albumin solution; and Group B was administered only albumin solution. Wedge biopsie of the allograft were harvested after 15 min flushing time and the gene expression profile were determined.

Description
Cholestasis may cause cholemic nephropathy that can be modelled in common bile duct ligated (CBDL) mice. We aimed to explore the therapeutic efficacy and mechanisms of norursodeoxycholic acid (norUDCA) in cholemic nephropathy. To determine whether norUrsodeoxycholic acid (norUDCA) prevents cholemic nephropathy in long-term CBDL mice, a norUDCA-enriched diet (0.125% w/v, corresponding to 200 mg/kg/day for a mouse of 25 g body weight eating about 4g daily) or a standard mouse diet (Sniff, Soest, Germany) were started 5 days prior to CBDL and were continued until harvesting 3 weeks thereafter. For transcriptional profiling using microarray technology, we compared sham-operated (SOP) mice and 3-week CBDL mice that were either fed 0.125% norUDCA-enriched or standard mouse diets.

Description
Pediatric acute myeloid leukemia (AML) is a heterogeneous disease characterized by non-random genetic aberrations related to outcome. Detecting these aberrations however still lead to failures or false negative results. Therefore, we focused on the potential of gene expression profiles (GEP) to classify pediatric AML.

Description
The aim of this experiment was to investigate differential gene expression in splenocytes stimulated with BCG from nave and BCG vaccinated mice. The differences between nave and BCG vaccinated mice might indicate the mechanisms by which BCG vaccination confers an enhanced ability of splenocytes from BCG vaccinated mice to inhibit growth of BCG in splenocyte cultures as compared with splenocytes from naive animals.

Transient expression of two factors, or from Oct4 alone, resulted in efficient generation of human iPSCs. The reprogramming strategy described revealed a potential transcriptional signature for human iPSCs yet retaining the gene expression of donor cells in human reprogrammed cells free of viral and transgene interference.

Description
Human medulloblastoma (MB) can be segregated into four major categories based on gene expression patterns: Hedgehog (HH) subtype, Wnt subtype, Group 3, and Group 4. However, they all exhibit strikingly different gene expression profiles from Atypical Teratoid/Rhabdoid Tumor (AT/RT). We re-analyzed published gene expression microarray dataset of pediatric brain tumors to identify a gene expression profile that clearly distinguished human AT/RT from human MB. We used this profile, choosing only genes that have clear murine orthologs, to compare tumors from Snf5F/Fp53L/LGFAP-Cre mice (in C57Bl/6 strain background) with MB from Ptc1+/- mice (in mixed C57Bl/6 and 129Sv strain background). Snf5F/Fp53L/LGFAP-Cre tumors are clearly very different from mouse MB and the markers that distinguish human AT/RT from human MB also distinguish the mouse tumors.
