Project description:Previous studies reported that mice living in an enriched environment (EE) showed reduced growth of melanoma, colon and breast tumors. Our study extended the potential anti-tumor effect of EE exposure to pancreatic cancer, and firstly provided evidence demonstrating that EE exposure significantly inhibits tumor growth in a syngeneic murine model of pancreatic cancer. To further investigate the mechanisms underlying the EE-induced pancreatic tumor inhibition, we analyzed the gene expression changes in pancreatic tumor xenograft using an integrative transcriptomic and proteomic approach. Our results found that EE largely decreased the expression of genes associated with mitochondrial function at transcriptional level in pancreatic tumor, suggesting mitochondrial dysfunction in tumor cells may play a critical role in EE-induced anti-tumor phenotype. Three-week-old C57BL/6 mice were randomized to live in either enriched environment or standard environment conditions. Mice from both groups were given subcutaneous injection of Panc02 murine pancreatic cancer cells (6 M-CM-^W 105 cells per mouse) and lived in their respective homes for 5 additional weeks. Pooled RNA samples extracted from Panc02 tumors (6 mice for each group) were then subjected to Agilent-014868 Whole Mouse Genome 4M-bM-^XM-^S44k Microarray analyses.

Project description:C57BL6/J female mice were raised either in standard environment (SE) for 8 weeks after birth or were put in enriched environment (EE) at postnatal 4 weeks up to 8 weeks old. Mice were sacrificed at 8 weeks and spleen were harvested. CD4+ and CD8+ T cells were sorted by FACS and CD4+ or CD8+ T were profiled using a low-input protocol adapted from single-cell RNAseq.

Project description:Recent genomic studies suggest that a single gene is involved in multiple diseases, however it is unclear what mechanism destined for different diseases by a single gene. Mutations of ZBTB16 are associated with autism spectrum disorder (ASD) and schizophrenia (SCZ), but how ZBTB16 fates ASD or SCZ are unknown. Here we show the deletion of Zbtb16 in mice leads to both ASD- and SCZ-like behaviors such as social impairment, repetitive behaviors, risk-taking behaviors, and cognitive impairment. To elucidate the mechanism underlying the behavioral phenotypes, we carried out histological studies and observed impairments in thinning of neocortical layer 6 (L6) and a reduction of TBR1+ neurons in the prefrontal cortex (PFC) of Zbtb16 KO mice. Furthermore, we found increased dendritic spines and microglia as well as developmental defects in oligodendrocytes and neocortical myelination in the PFC of Zbtb16 KO mice. Using a genomics approach, we identified the Zbtb16-transcriptome that includes genes involved in both ASD and SCZ pathophysiology and neocortical maturation such as neurogenesis and myelination. Co-expression networks further identified Zbtb16-correlated modules that are unique to ASD or SCZ respectively. Our study provides insight into the differential role of the single gene ZBTB16 in ASD and SCZ.

Project 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. To identify those genes whose expression was altered in the hippocampus of cbp heterozygous mice both under basal conditions and after 2 weeks of exposure to environmental enrichment, we performed a gene profiling analysis of hippocampal tissue using high-density oligonucleotide microarrays. We obtained quintuplicate (standard housing) and triplicate (environmental enrichment) samples containing total RNA from the hippocampi of four 3-month old females of either genotype (in total 32 cbp+/- mice and 32 wild type littermates were used in the experiment).

Project description:Wildtype Swiss webster mice were exposed to four weeks of either standard housing (SH) or environmental enrichment (EE) starting at one month of age. EE chambers were large mouse cages containing two nesting/burrowing materials, a running wheel, and toys that were changed every 3-4 days for novelty and exploration. By contrast, SH control mice were housed with an equal number of littermates in smaller, standard cages containing only one nesting material and no toys or running wheel. We used an antibody for Rbfox3 (NeuN) to sort neuronal nuclei from the dissociated frontal cortices of male mice reared in EE and SH conditions. Isolated neuronal nuclei were then subjected to ATAC-seq or nuclear RNA isolation (random hexamer priming) as per published protocols.

Project description:Environmental enrichment (EE) conditions have profound beneficial effects for reinstating cognitive ability in neuropathological disorders like Alzheimerâs disease (AD). While EE benefits involve epigenetic gene control mechanisms that comprise histone acetylation, the histone acetyltransferases (HATs) involved remain largely unknown. Here, we examine a role for Tip60 HAT action in mediating activity- dependent beneficial neuroadaptations to EE using the Drosophila CNS mushroom body (MB) as a well-characterized cognition model. We show that flies raised under EE conditions display enhanced MB axonal outgrowth, synapse protein production, histone acetylation induction and transcriptional activation of cognition linked genes when compared to their genotypically identical siblings raised under isolated conditions. Further, these beneficial changes are impaired in both Tip60 HAT mutant flies and APP neurodegenerative flies. While EE conditions provide only slight beneficial neuroadaptive changes in the APP neurodegenerative fly MB, such positive changes are significantly enhanced by increasing MB Tip60 HAT levels. Our results implicate Tip60 as a critical mediator of EE-induced benefits, and provide insight into synergistic behavioral and epigenetic based approaches for treatment of cognitive disorders. EE has been shown to positively impact gene expression profiles in the mouse brain that are enriched in functions such as neuronal structure, synaptic plasticity and neurotransmission. Thus, we asked whether the EE induced beneficial MB structural and synaptic changes we observe are accompanied by neuroadaptive transcriptional benefits in the Drosophila MB, and if so, is Tip60 HAT action required for this process. To address this question, we accessed EE induced beneficial transcriptional changes using microarray. We crossed our UAS-mCD8-GFP;Tip60E431Q flies or control UAS-mCD8-GFP flies to MB GAL4 OK-107 to simultaneously induce Tip60 HAT loss in the MB while tagging MB cells with GFP. Adult progeny were exposed to EE or ISO conditions. After conditioning, the GFP tagged MB Kenyon neurons were FACs purified from conditioned fly brains from each genotype to enrich for detection of an EE induced MB transcriptional response. RNA was isolated from the purified Kenyon MB neurons and transcriptional changes for each genotype were assessed using microarray analysis
