Description
Neutrophils represent a fundamental mechanism of antimicrobial resistance and inflammation 1. Moreover, neutrophils have emerged as important players in the activation, orchestration and regulation of adaptive immune responses2,3. Neutrophils are a component of the tumor microenvironment (TME) and have been prevalently shown to promote progression 4-6. On the other hand, unleashed neutrophilic effectors have also been reported to mediate anti-cancer resistance7-11. Antibody-mediated depletion used to investigate the role of neutrophils in tumor progression suffers from limitations, including duration, specificity and perturbation of the system12. We therefore used a genetic approach to investigate the role of neutrophils in primary 3-methylcholanthrene (3-MCA)-induced sarcomagenesis. Neutrophils were found to play an essential role in resistance against primary carcinogenesis by driving an interferon-? dependent type 1 immune response. Neutrophil-dependent macrophage production of IL-12p70 led to type 1 polarization of CD4- CD8- unconventional aß T cells (UTCaß) in the TME. Single cell RNAseq analysis and in vivo evidence from two preclinical sarcoma models highlight the antitumor potential of a UTCaß subset. In the TCGA cohort of human undifferentiated pleomorphic sarcomas (UPS), unlike other sarcomas, granulocyte-colony stimulating factor receptor (CSF3R) expression and a neutrophil signature were associated with better outcome and with a type 1 immune response. The positive association between high neutrophil infiltration and improved clinical outcome was confirmed in an independent UPS cohort by immunohistochemistry. Thus, neutrophils, by driving a type 1 immune response and polarization of UTCaß, mediate resistance against murine and human sarcomas. Overall design: two experimental conditions, two biological replicates for each condition

Description
Cystic fibrosis transmembrane conductance regulator (Cftr) knockout mice present the clinical features of low body weight and intestinal disease permitting an assessment of the interrelatedness of these phenotypes in a controlled environment. To identify intestinal alterations which affect body weight in CF mice the histological phenotypes of crypt-villus axis height, goblet cell hyperplasia, and mast cell infiltrate were measured, cardiac blood samples assessed, and gene expression profiling of the ileum was completed for 12 week old (C57BL/6xBALB) F2 Cftrtm1UNC and non-CF mice presenting a range of body weight. Crypt-villus axis height decreased with increasing weight in CF, but not control, mice. Goblet cell hyperplasia and mast cell infiltration in the submucosa and muscularis externa layers of the CF intestine, were identified to be independent of bodyweight. Blood triglyceride levels were found to be significantly lower in CF mice than control mice (p = 3.02 x 10-5) but were not dependent on CF mouse body weight. By expression profiling, genes of DNA replication and lipid metabolism were among those altered in CF mice relative to non-CF controls; and no differences in gene expression were measured between samples from CF mice in the 25th and 75th percentile for weight. This study indicates that the absence of Cftr leads to altered morphology in the CF intestine the extent of which is correlated with body weight in CF mice while CF related changes in blood triglyceride levels and in the intestinal gene expression profile were not dependent on body weight in this model.

Description
HISRainbow mice were used to obtain mosaic ovaries for transcriptome analysis of MII eggs expressing H3.3-eGFP, H3.3R26K-eCFP, or H3.3K27R-mCherry. Results provide comparison of eggs with different genotypes and insight into mechanism of how resting oocytes are selected for ovulation. Overall design: Transcriptome profiling of eggs expressing H3.3-eGFP, H3.3R26K-eCFP, or H3.3K27R-mCherry by deep sequencing in duplicates.

Description
The epigenetic changes of the chromatin represent an attractive molecular substrate for adaptation to the environment. We examined here the role of CBP, a histone acetyltransferase involved in mental retardation, in the genesis and maintenance of long-lasting systemic and behavioral adaptations to environmental enrichment (EE). Morphological and behavioral analyses demonstrated that EE ameliorates deficits associated to CBP-deficiency. However, CBP-deficient mice also showed a strong defect in environment-induced neurogenesis and impaired EE-enhanced spatial navigation and patter separation ability. These defects correlated with an attenuation of the transcriptional program induced in response to EE and with deficits in histone acetylation at the promoters of EE-regulated, neurogenesis-related genes. Additional experiments in CBP restricted and inducible knockout mice indicated that environment-induced adult neurogenesis is extrinsically regulated by CBP function in mature granule cells. Overall, our experiments demonstrate that the environment alters gene expression by impinging on activities involved in modifying the epigenome and identify CBP-dependent transcriptional neuroadaptation as an important mediator of EE-induced benefits, a finding with important implications for mental retardation therapeutics.

Description
A role of vitamin C (ascorbic acid) as an antioxidant molecule has been recognized, largely based on in vitro studies. However, more recently, the concept of antioxidant molecule has been reconsidered and its biological function is no longer considered to be simply due to its ability to act as electron donors, rather, it appears to act by modulating signaling and gene expression.

We found genetic deletion of IKK in mdx cardiomyocytes improved cardiac function and normalized calcium transients. We used microarrays to profile gene expression in hearts of mdx mice with intact IKK signaling and hearts of mdx mice with IKK-deficient cardiomyocytes to identify genes differentially regulated by NF-[kappa]B. signaling in dystrophic hearts.
