Description
The cellular ontogeny of hematopoietic stem cells (HSCs) remains poorly understood because their isolation from and their identification in early developing small embryos are difficult. We attempted to dissect early developmental stages of HSCs using an in vitro mouse embryonic stem cell (ESC) differentiation system combined with inducible HOXB4 expression. Here we report the identification of pre-HSCs and an embryonic type of HSCs (embryonic HSCs) as intermediate cells between ESCs and HSCs. Both pre-HSCs and embryonic HSCs were isolated by their c-Kit+CD41+CD45- phenotype. Pre-HSCs did not engraft in irradiated adult mice. After co-culture with OP9 stromal cells and conditional expression of HOXB4, pre-HSCs gave rise to embryonic HSCs capable of engraftment and long-term reconstitution in irradiated adult mice. Blast colony assays revealed that most hemangioblast activity was detected apart from the pre-HSC population, implying the early divergence of pre-HSCs from hemangioblasts. Gene expression profiling suggests that a particular set of transcripts closely associated with adult HSCs is involved in the transition of pre-HSC to embryonic HSCs.

Description
KRAP (Ki-ras-induced actin-interacting protein) is a cytoskeleton-associated protein and a ubiquitous protein among tissues, originally identified as a cancer-related molecule. KRAP-deficient (KRAP-/-) mice show enhanced metabolic rate, decreased adiposity, improved glucose tolerance, hypoinsulinemia and hypoleptinemia. KRAP-/- mice are also protected against high-fat diet-induced obesity and insulin resistance despite of hyperphagia.

Altered energy homeostasis and resistance to diet-induced obesity in KRAP-deficient mice.

Description
Treatment of DBA/2J mice with a combination of L-methionine and valproic acid significantly attenuated progressive hearing loss. We examined gene expression in the whole cochlea of the mice. This study was aimed to detect genes of which change in expression levels were associated with attenuation of progressive hearing loss in the mice.
Publication Title
Attenuation of progressive hearing loss in DBA/2J mice by reagents that affect epigenetic modifications is associated with up-regulation of the zinc importer Zip4.

Description
We previously found that mice with heterozygous knockout of the alpha-isoform of calcium/calmodulin-dependent protein kinase II (alpha-CaMKII HKO mice) show various dysregulated behaviors, including cyclic variations in locomotor activity (LA), suggesting that alpha-CaMKII HKO mice may serve as an animal model showing infradian oscillation of mood. We performed gene expression microarray analysis of dentate gyrus from alpha-CaMKII HKO mice. Mice were selected for the sampling such that their LA levels varied among the mice.

Description
To clarify how Foxp3 regulates its target genes, we performed co-immunoprecipitation experiments and found that Foxp3 physically bound to AML1/Runx1 (Ono, M. et al, Nature, 2007). In this series of study, we compared gene regulations by AML1, wild type Foxp3, and a Foxp3 mutant with defective binding to AML1.

Description
Epigenetically silenced Ink4a-Arf locus is activated by loss of H3K27me3 in cellular senescence, where secreted factor expression is also involved. Here we analyzed epigenome and transcriptome alteration during Ras-induced senescence using mouse embryonic fibroblast (MEF). Seventeen genes with H3K27me3 loss and H3K4me3 gain showed marked upregulation, including p16Ink4a and Bmp2, a secreted factor for BMP/SMAD signal. Smad6, specific BMP/SMAD pathway inhibitor, was identified as the only one gene showing de novo H3K27 trimethylation with H3K4me3, resulting in strong repression. Ras-activated cells senesced with SMAD1/5/8 phosphorylation, and they escaped from senescence with decreased SMAD1/5/8 phosphorylation when introducing Smad6 or knocking-down Bmp2.
