Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
In chicks, the avian homologue of the early growth response protein-1 (ZENK) has been shown to be increased in a special cell type of the retina, the glucagonergic amacrine cells, under conditions that lead to a reduction in eye growth (myopic defocus, recovery of myopia) and decreased under conditions that enhance ocular growth (hyperopic defocus, form-deprivation). The investigation of Egr-1 knock-out mice showed that homozygous knock-out mice with no functional Egr-1 protein developed relative axial myopia at the age of 42 and 56 days, compared to heterozygous- and wildtype Egr-1 knock-out mice.

Description
The retina plays an important regulatory role in ocular growth. To screen for new retinal candidate genes that could be involved in the inhibition of ocular growth, we used chick microarrays to analyze the changes in retinal mRNA expression after myopic defocus was imposed by positive lens-wear.

Description
Transplanting renal allografts represents the major curative treatment of chronic renal failure. Despite recent advances in immunosuppressive therapy, long-term survival of allografts remains a major clinical problem. Kidney function depends in part on transport proteins such as MRP2 (ABCC2) which facilitates renal secretion of amphiphilic exogenous and endogenous compounds. Inherited variants of genes not related to the immune system have been shown to modify the outcome after renal transplantation. We investigated whether ABCC2 gene variants in the donor kidney affect renal graft function.

Description
Studies investigating the causes of autism spectrum disorder (ASD) point to genetic as well as epigenetic mechanisms of the disease. Identification of epigenetic processes that contribute to ASD development and progression is of major importance and may lead to the development of novel therapeutic strategies. Here we identify the bromodomain and extra-terminal domain containing transcriptional regulators (BETs) as epigenetic drivers of an ASD-like disorder in mice. We found that the pharmacological suppression of the BET proteins by a novel, highly selective and brain-permeable inhibitor, I-BET858, leads to selective suppression of neuronal gene expression followed by the development of an autism-like syndrome in mice. Many of the I-BET858 affected genes have been linked to ASD in humans thus suggesting the key role of the BET-controlled gene network in ASD. Our studies also suggest that environmental factors controlling BET proteins or their target genes may contribute to the epigenetic mechanism of ASD.

Description
Naturally occurring variations of Polycomb Repressive Complex 1 (PRC1) comprise a core assembly of Polycomb group proteins and additional factors that include, surprisingly, Autism Susceptibility Candidate 2 (AUTS2). While AUTS2 is often disrupted in patients with neuronal disorders, the underlying mechanism is unclear. We investigated the role of AUTS2 as part of a previously identified PRC1 complex (PRC1-AUTS2), and in the context of neurodevelopment. In contrast to the canonical role of PRC1 in gene repression, PRC1-AUTS2 activates transcription. Biochemical studies demonstrate that the CK2 component of PRC1-AUTS2 thwarts PRC1 repressive activity and AUTS2-mediated recruitment of P300 leads to gene activation. ChIP-seq of AUTS2 shows that it regulates neuronal gene expression through promoter association. Conditional CNS targeting of Auts2 in a mouse model leads to various developmental defects. These findings reveal a natural means of subverting PRC1 activity, linking key epigenetic modulators with neuronal functions and diseases. Overall design: mRNA profiles of P1 brain from wild type mice were generated by deep sequencing

Cebpa is a gene known for its role in hematopoetic development. Though it is proven to be indispensible in myelopoesis, the details of the role played by Cebpa in dendritic cell development is fairly unknown. Steady state DC development can be modelled in vitro by treating Lin- HSPC with FLT3L.

Description
Genetically engineered human pluripotent stem cells (hPSCs) have been proposed as a source for transplantation therapies and are rapidly becoming valuable tools for human disease modeling. However, many of the potential applications are still limited by the lack of robust differentiation paradigms that allow for the isolation of defined functional tissues. These challenges could be overcome by the use of adult tissue stem cells derived from hPSCs, as their restricted potential could limit the differentiation towards other undesired linages, and allow in vitro expansion and long- term propagation of fully differentiated tissue. To isolate adult stem cells from hPSCs, we applied genome-editing to generate an LGR5-GFP reporter system and subsequently developed a differentiation protocol for human intestinal tissue comprising an adult stem cell niche and all major cell types of the adult intestine. This novel derivation protocol is highly robust and even permits the isolation of intestinal organoids without the LGR5 reporter. Transcriptional profiling, electron microscopy and functional analysis revealed that such human organoid cultures could be derived with high purity, and a composition and morphology similar to that of cultures obtained from human biopsies. Importantly, hPSC-derived organoids responded to the canonical signaling pathways that control self-renewal and differentiation in the adult human intestinal stem cell compartment. With our ability to genetically engineer hPSCs using site-specific nucleases, this adult stem cell system provides a novel platform by which to study human intestinal disease in vitro. Overall design: RNA from primary organoid samples was isolated from organoid lines that were both cultured for 1-6 months and derived from duodenum, ileum, or rectum biopsies of human subjects as described previously (Sato et al., Gastroenterology 2011) grown in media called WENR+inhibitors. RNA was also isolated from various steps in the culturing and differentiation protocol.
