Affymetrix Mouse Gene 2.0 ST Array (mogene20st)
Description
To study the effects of previous exposure to mechanical ventilation may modify the development of Ventilator-induced lung injury, preconditioning was induced by low-pressure ventilation for 90 minutes. After 1 week, intact (sham) and preconditioned mice were sacrificed, the lungs extracted and gene expression measured in order to identify differences responsible for the observed tolerance to ventilator-induced lung injury observed in preconditioned animals.

Illumina HiSeq 2500
Description
We investigated the ability of monoclonal B cells to restore primary and secondary antibody responses in adoptive immune-deficient hosts. Priming induced B cell activation and expansion, AID expression, antibody production and the generation of IgM+IgG- and IgM-IgG+ antigen-experienced B-cell subsets that persisted in the lymphopenic environment by cell division. Using RNA sequencing, we compared the gene expression profil of memory B cells subpopulations and activated B cells. These data showed a clear discrimination of naïve and activated/memory cells while indicating only minor differences between both subsets of memory cells. Overall design: mRNA profiles of B cell subtypes (activated, memory IgM+, memory IgG+) were generated by deep sequencing, in triplicate, using Illumina

Description
Abstract: Choline is an essential nutrient and methyl donor required for epigenetic regulation. Here, we assess the impact of gut microbial choline metabolism on bacterial fitness and host biology by engineering a microbial community to lack a single choline-utilizing enzyme. Our results indicate that choline-utilizing bacteria compete with the host for this nutrient, significantly impacting plasma and hepatic levels of methyl-donor metabolites recapitulating biochemical signatures of choline deficiency. Mice harboring high levels of choline-consuming bacteria show increased susceptibility to metabolic disease. Furthermore, bacterially-induced reduction of methyl-donor availability alters global DNA methylation patterns in both adult mice and their offspring in utero and engenders anxious behavior. Altogether, our results reveal an underappreciated aspect of bacterial choline metabolism (i.e., methyl-donor depletion) that is linked to alterations in metabolism, epigenetics, and behavior. More broadly, this work suggests that interpersonal differences in microbial metabolism should be considered when determining optimal levels of nutrient intake. Overall design: 8 samples in total (biological n=4 per for each defined community; 9kw old female C57BL/6 mouse liver; 2 weeks of colonization and maintenance on 1% choline diet; 4hours of fasting prior to sacrifice)

Description
The neural transcription factor SOX11 is overexpressed in aggressive lymphoid neoplasms mainly in mantle cell lymphoma (MCL). We have recently demonstrated SOX11 tumorigenic potential in vivo by showing a significant reduction on tumor growth of SOX11-knockdown MCL cells in xenograft experiments, confirming the clinical observations that SOX11 may play an important role in the aggressive behavior of MCL (Vegliante et al., 2013). However, the specific mechanisms regulated by SOX11 that promote the oncogenic and rapid tumor growth of aggressive MCL still remain to be elucidated. To further characterize the potential oncogenic mechanisms regulated by SOX11 in MCL, we have analyzed the GEP derived from the xenograft SOX11-positive and knockdown xenograft derived tumors.

Affymetrix Human Transcriptome Array 2.0 (hta20), Illumina HiSeq 2000
Description
Long noncoding RNAs (lncRNAs) have appeared to be involved in the most diverse cellular processes through multiple mechanisms. Here we describe a previously uncharacterized human lncRNA, CONCR (cohesion regulator noncoding RNA), transcriptionally activated by MYC, which is upregulated in multiple cancer types. The expression of CONCR is cell cycle-regulated, and it is required for cell cycle progression and DNA replication. Moreover, cells depleted of CONCR show severe defects in sister chromatid cohesion, suggesting an essential role for CONCR in cohesion establishment during cell division. CONCR interacts with and regulates the activity of DDX11, a DNA-dependent ATPase and helicase involved in DNA replication. These findings suggest a novel mechanism of action for CONCR in the modulation of DDX11 enzymatic activity, unveiling the direct involvement of a lncRNA in the establishment of sister chromatid cohesion.
