- Affymetrix Human Genome U133A 2.0 Array (hgu133a2)
Description
The deposition of unconjugated bilirubin (UCB) in selected regions of the brain results in irreversible neuronal damage, or Bilirubin Encephalopathy (BE). Although UCB impairs a large number of cellular functions, the basic mechanisms of neurotoxicity have not yet been fully clarified. While cells can accumulate UCB by passive diffusion, cell protection may involve multiple mechanisms including the extrusion of the pigment as well as pro-survival homeostatic responses that are still unknown. The effects of UCB treatment to SH-SY5Y neuroblastoma cell line were examined by high density oligonucleotide microarrays. 230 genes were induced after 24 hours. A Gene Ontology (GO) analysis showed that a large group of UCB-induced genes were components of the ER stress response. Independent experimental validation of molecular events crucial for the ER stress response is presented. The results show that UCB exposure induces ER stress response as major intracellular homeostatic response in neuroblastoma cells in vitro. Our finding may provide valuable information for new therapeutic strategies in the treatment of BE.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
We identified DNAPK as one of the major proteins that physically interact with Autoimmune regulator (Aire). To establish physiological significance of DNAPK in Aire-driven expression of PTA genes in MECs, we utilized BM-reconstituted SCID mice (which express non functional DNAPK in their MECs) and RAG1 null mouse as a control.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
To analyze the impact of Aire on gene expression profile in a model cell line, we used 293T cells and transfected them either with an Aire expression plasmid pCMV-Aire (where mAire is driven by CMV promoter) or with a control plasmid pCMV2B.

Illumina HiSeq 2000
Description
Background: In order to become functionally competent but harmless mediators of the immune system, T cells undergo a strict educational program in the thymus, where they learn to discriminate between self and non-self. This educational program is, to a large extent, mediated by medullary thymic epithelial cells (mTECs) that have a unique capacity to express, and subsequently present a large fraction of body antigens. While the scope of promiscuously expressed genes by mTECs is well established, relatively little is known about the expression of variants that are generated by co- and post-transcriptional processes. Results: Our study reveals that in comparison to other cell types, mTECs display significantly higher levels of alternative splicing, as well as A-to-I and C-to-U RNA editing, which thereby further expand the diversity of their self-antigen repertoire. Interestingly, Aire, the key mediator of mTECs promiscuous gene expression, plays a limited role in the regulation of these transcriptional processes. Conclusions: Our results highlight RNA processing as another layer by which the immune system assures a comprehensive self-representation in the thymus which is required for the establishment of self-tolerance and prevention of autoimmunity. Identification of the number of genes expressed in Aire-KO MEChi Overall design: ~100ng of total RNA was isolated by Trizol extraction from MHC-II high mTECs from a pool of 3 Aire-KO mice. Poly-A-selected transcriptome libraries were generated using the non-directionnal TruSeq V3 RNA Sample Prep Kit (without additional pre-amplification) following the manufacturer''s protocols. Enrichment of DNA fragment with adapter molecules on both ends was done using 15 cycles of PCR amplification using the Illumina PCR mix and primer cocktail. Paired-end (2 × 100 bp) sequencing was performed using the Illumina HiSeq2000 machine.
