- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
The mammalian Retinoblastoma (RB) family including pRB, p107, and p130 represses E2F target genes through mechanisms that are not fully understood. In D. melanogaster, RB-dependent repression is mediated in part by the multisubunit protein complex Drosophila RBF, E2F, and Myb (dREAM) that contains homologs of the C. elegans synthetic multivulva class B (synMuvB) gene products. Using an integrated approach combining proteomics, genomics, and bioinformatic analyses, we identified a p130 complex termed DP, RB-like, E2F, and MuvB (DREAM) that contains mammalian homologs of synMuvB proteins LIN-9, LIN-37, LIN-52, LIN-54, and LIN-53/RBBP4. DREAM bound to more than 800 human promoters in G0 and was required for repression of E2F target genes. In S phase, MuvB proteins dissociated from p130 and formed a distinct submodule that bound MYB. This work reveals an evolutionarily conserved multisubunit protein complex that contains p130 and E2F4, but not pRB, and mediates the repression of cell cycle-dependent genes in quiescence.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Retinal damage causes proliferation of Muller glia, but the degree of proliferation depends on mouse strains. Muller glial proliferation was significantly promoted by the addition of GSK3 inhibitor in 129, but not in B6. We used retinal explant culture as a model for retinal damage which caused preferential photoreceptor death in a few days.

Proliferation potential of Müller glia after retinal damage varies between mouse strains.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Quiescent hair follicle (HF) bulge stem cells (SCs) differentiate to early progenitor (EP) hair germ (HG) cells, which divide to produce transit-amplifying (TA) matrix cells. EPs can revert to SCs upon injury, but whether this de-differentiation occurs in normal HF homeostasis (hair cycle), and the mechanisms regulating both differentiation and de-differentiation are unclear. Here we use lineage tracing, gain of function, transcriptional profiling, and functional assays to examine the role of observed endogenous Runx1 level changes in the hair cycle. We find that forced Runx1 expression implements hair degeneration (catagen) and simultaneously promotes changes in the quiescent bulge SC transcriptome towards a cell-state resembling the EP HG fate. This cell-state transition is functionally reversible. We propose that SC differentiation and de-differentiation are likely to occur during normal HF degeneration and niche restructuring in response to changes in endogenous Runx1 levels associated with SC location with respect to the niche.
Publication Title
High Runx1 levels promote a reversible, more-differentiated cell state in hair-follicle stem cells during quiescence.

Description
Memory B cells play essential roles in the maintenance of long-term immunity and may be important in the pathogenesis of autoimmune disease, but how these cells are distinguished from their nave precursors is poorly understood. To address this, it would be important to understand how gene expression differs between memory and naive B cells in order to elucidate memory-specific functions. Using model systems that help overcome the lack of murine memory-specific markers and the low frequency of antigen-specific memory and nave cells, we undertook a global comparison of gene expression between memory B cells and their naive precursors.
Publication Title
Systematic comparison of gene expression between murine memory and naive B cells demonstrates that memory B cells have unique signaling capabilities.

Illumina HiSeq 4000
Description
Whole blood RNA-seq was leveraged to explore gene expression changes induced in mice 24 hours after immunisation with a second dose of a licensed vaccine against capsular group B meningococcus, one of the vaccines components, or one of several comparator groups. Overall design: mRNA was profiled from RNA extracted from mouse whole blood, 5-6 samples per group, using an Illumina HiSeq4000
Publication Title
Comparative transcriptomics between species attributes reactogenicity pathways induced by the capsular group B meningococcal vaccine, 4CMenB, to the membrane-bound endotoxin of its outer membrane vesicle component.

Description
Obesity is thought to contribute to worse disease outcome in breast cancer as a result of increased levels of adipocyte-secreted endocrine factors, insulin, and insulin-like growth factors (IGFs) that accelerate tumor cell proliferation and impair treatment response. We examined the effects of patient obesity on primary breast tumor gene expression, by profiling transcription of a set of tumors for which the patients body mass index (BMI) was ascertained. Sample profiles were stratified according to patients obesity phenotype defined as normal (BMI <25), overweight (BMI 25-29.9), or obese (BMI>30). Widespread alterations in gene expression were evident in breast tumors from obese patients as compared to tumors from other patients, allowing us to define an obesity-associated cancer transcriptional signature of 662 genes.
