Description
Innate memory phenotype (IMP) CD4+ T cells are non-conventional T cells exhibiting features of innate immune cells, characterized as CD44high and CD62Llow in periphery. It is recently reported by our group that bone marrow chimeric mice lacking thymic MHCI expression develop predominantly IMP CD8+ T cells, while those lacking hematopoietic MHCI develop predominantly nave CD8+ T cells. Here we perform hirarchical clustering analysis and found that CD4+ T cells share similar property: chimeras lacking thymic MHCII gave rise to predominantly CD4+ T cells that resemble IMP CD4+ T cells observed in WT mice, and vice versa, chimeras lacking hematopoietic MHCII had a majority of nave-like CD4+ T cells resembling naveCD4+ T cells seen in WT mice.

Description
Moderate alcohol consumption during pregnancy can result in a heterogeneous range of neurobehavioural and cognitive effects, termed fetal alcohol spectrum disorders (FASD). We have developed a mouse moder of FASD that involves moderate ethanol exposure throughout gestation achieved by voluntary maternal consumption. This model results in phenotypes relevant to FASD. Since ethanol is known to directly affect the expression of genes in the developing brain leading to abnormal cell death, changes to cell proliferation, migration, and differentiation, and potential changes to epigenetic patterning, we hypothesize that this leaves a long-term footprint on the adult brain. However, the long-term effects of prenatal ethanol exposure on brain gene expression, when behavioural phenotypes are apparent, are unclear.

Mouse models of Fetal Alcohol Spectrum Disorder can be used to assess molecular changes underlying the disorder. Neonatal ethanol exposure in mice can be used to model third trimester ethanol exposure in humans.

Description
The developing brain is particularly sensitive to ethanol during the brain growth spurt or synaptogenesis (third human trimester equivalent). This has been shown to lead to abnormal brain development and behavioural changes in the adult mouse that are relevant to those seen in humans with fetal alcohol spectrum disorders (FASD). We evaluated the long-term (postnatal day 60 young adult) gene expression changes that occur in the brain due to ethanol exposure during synaptogenesis.

Description
The quality of maternal care in early-life plays a crucial role in mammalian neurodevelopment. Augmented maternal care (AMC) is a well-established rodent model of enhanced neonatal care. Rats that have undergone AMC have improved stress resilience and cognition compared with rats that have experienced normal levels of maternal care or adverse neonatal stress. However, the epigenomic basis of long-lived responses to AMC has not been previously explored. Thus, we employed whole-genome bisulfite sequencing (WGBS), RNA-sequencing (RNA-seq), and a multiplex microRNA (miRNA) assay to assess DNA cytosine methylation, gene expression, and miRNA expression, respectively. The integrated results identify a suite of 20 prioritized candidates impacted by AMC. Overall, these results identified AMC-induced regulatory differences in genes related to neurotransmission, neurodevelopment, protein synthesis, and oxidative phosphorylation in addition to the expected stress response genes. Together, these unbiased results represent a key progression in understanding the complex mechanisms underlying the early-life mechanisms for AMC programming stress resiliency. Overall design: DNA methylation and RNA were assayed in augmented maternal care male rats as well as controls.

Description
Reprogramming of somatic cells into induced pluripotent stem cells (iPSC) is an epigenetic phenomenon. We have reprogrammed mesenchymal stromal cells (MSC) from human bone marrow by retrovirus-mediated overexpression of OCT-3/4, SOX2, c-MYC, and KLF4. This series summarizes gene expression profiles of eight iP-MSC clones derived from three different donors. These datasets were subsequently used for PluriTest analysis (Muller FJ, Schuldt B et al., Nat. Methods 2011; 8: 315-317) demonstrating that all iP-MSC clones were clearly associated with pluripotent cells.
