Affymetrix Human Genome U219 Array (hgu219), Illumina HiSeq 2000
Description
Molecular mechanisms underlying terminal differentiation of B-cells into plasma cells are major determinants of adaptive immunity but remain only partially understood. Here, we present the transcriptional and epigenomic landscapes of cell subsets arising from activation of human naive B-cells and differentiation into plasmablasts. Cell proliferation of activated B cells was linked to a slight decrease in DNA methylation levels but followed by a committal step in which an S-phase-synchronized differentiation switch was associated with an extensive DNA demethylation and local acquisition of 5-hydroxymethylcytosine at enhancers and genes related to plasma cell identity.

Description
Environmental factors such as pesticides are widely used in the agriculture of many countries and their negative impact on human health and fertility are largely unknown. There is a rapidly growing body of evidence that human reproductive health is negatively affected by the various environmental factors, including life style and exposure to the chemical compounds such as certain drugs and pesticides. Sexually reproducing organisms produce haploid gametes via a process called meiosis. Meiosis is dependent on androgen action within the testis. Pesticides and herbicides interfere with natural hormones system and are considered to be endocrine disruptors. We hypothesize that atrazine (ATZ), a herbicide used globally, adversely affects meiosis. To test this idea we used the mouse as a model organism. Mice were treated three weeks with atrazine in drinking water at concentration of 100 mg/l. To assess the molecular mechanisms of effects of ATZ on spermatogenesis we performed comparative analysis of genes expression by using Affymetrix microarray by using three biological testis samples from ATZ treated and control mice. Using a fold-change cutoff value of 1.5 and p value <0.05 (statistical Limma test (linear models test for microarray data)), we identified 51 genes that were differentially expressed in ATZ treated mice.

Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Cerebellar post-natal development is particularly sensitive to thyroid hormone and low levels of thyroid hormone (hypothyroidism) result in permanent defects in cerebellar architecture and function. All cell types of the cerebellum are affected, but the main sign of hypothyroidism in mice is the persistence of the external granular layer, composed of mitotic neuronal precursors at P21.

To explore events that govern the differentiation of human nave B cells (NBCs) into memory B cells and plasma cells (PCs), we designed an in vitro 2-step culture model leading non-switched NBC precursors to differentiate into two cell compartments: CD20loCD38hi and CD20+CD38+.

Description
Tumor infiltrating neutrophils (TAN) have been shown to exert both pro- and anti-tumoral activities and their recruitment and polarization are triggered by tumor-derived signals. Resident mesenchymal stromal cells (MSC) could contribute to tumor-supportive cell niche and have been shown to display tumor-specific transcriptomic, phenotypic, and functional features compared to normal tissue. In our study, we investigate whether these two cell subsets establish a bidirectional crosstalk in the context of B-cell lymphoma.

Description
Based on the developmental origin of health of disease hypothesis, we previously showed that prenatal 70% maternal food restriction (FR30) predisposes the offspring to development of pathologies in adulthood. In the present study, we focused on the liver gene expression profile of standard and high fat (HF)-fed FR30 adult offspring.
