NIH3T3 in the middle of G0 to G1 transion consists of the cells which is still staying G0 phase and the cells which enters G1. Monitoring the expressions of p27 and Cdt1 enables to distinguish these two; p27+/Cdt1+ cells as the cells in G0 phase and p27-Cdt1+ cells as G1 phase
A novel cell-cycle-indicator, mVenus-p27K-, identifies quiescent cells and visualizes G0-G1 transition.

View SamplesAlthough LIPUS has been shown to enhance fracture healing, the underlying mechanism of LIPUS remains to be fully elucidated. Here, to understand the molecular mechanism underlying cellular responses to LIPUS, we investigated gene expression profiles in mouse MC3T3-E1 preosteoblast cells using a GeneChip system.

View SamplesGerminal centers (GCs) are clusters of activated B cells built on stromal cells known as follicular dendritic cells (FDCs). In the Peyers patches (PPs), GCs are chronically induced by bacteria and are the major sites for generation of gut IgA immune responses. Whether FDCs directly contribute to the IgA production in PP GCs is unknown.
The sensing of environmental stimuli by follicular dendritic cells promotes immunoglobulin A generation in the gut.

View SamplesSkeletal muscle mass is an important determinant of whole-body glucose disposal. We here show that mice (M-PDK1KO mice) with skeletal muscle–specific deficiency of 3'-phosphoinositide–dependent kinase 1 (PDK1), a key component of the phosphatidylinositol 3-kinase (PI3K) signaling pathway, manifest a reduced skeletal muscle mass under the static condition as well as impairment of exercise load–induced muscle hypertrophy.

View SamplesIn this study we compared genes expressed in the unbudded portion of the Wolffian duct with the isolated ureteric bud to find genes novel to early kidney development. We used the Affymetrix Rat Genome 230 2.0 Array to compare the unbudded tissues with the budded samples.

View SamplesProtein arginine methylation is a post-translational modification catalyzed by protein arginine methyltransferase (PRMT). To elucidate the role of PRMT5 in T cells, we generated T-cell specific PRMT5-deficient mice (Prmt5 flox/d Cd4-Cre mice) and found a severe loss of thymic iNKT cells as well as a reduced number in peripheral CD4+ and CD8+ T cells. As iNKT cells were significantly decreased in the stage 1, 2 and 3 of developmental stages, RNA-seq was performed using stage 1 iNKT cells of control and PRMT5-deficient mice. This transcriptome analysis will provide mechanistic insight into how PRMT5 contributes to thymic iNKT cell development. Overall design: Stage 1 iNKT cells were sorted from thymus of control and Prmt5 flox/D Cd4-Cre mice. Total RNA was extracted and RNA-seq was performed by Ion Proton.

View SamplesBacterial lipopolysaccharide(LPS) dramatically activates macrophages. So far, dozen of papers indicated that many proinflammatory molecules are transcriptionaly regulated during response. Despite of this,translational regulation is not fully elucidated especially in a comprehensive fashion. In this series, we investigated expression profiles of translation active (polysome) inactive (free mRNP) mRNAs of a typical mouse macrophage cell line, J774.1. Moreover, we also measured total cellular RNA level as a reference.

View SamplesTo analyse roles of HAI-1/Spint1 in intestinal tumorigenesis, we examined the effect of intestine-specific deletion of Spint1 gene on Apc(Min/+) mice. The loss of Hai-1/Spint1 significantly accelerated tumor formation in ApcMin/+ mice and shortened their survival periods.

View SamplesA distinct type of macrophages helps breast cancer cells to overcome rate-limiting steps in the metastatic process and establish lethal metastatic tumors. Since only a minor population of cancer cells can establish macroscopic metastatic tumors, we hypothesized that this metastatic cancer cell population have higher expression of receptors for macrophage-derived ligands compared to their parental cells.

View SamplesWe have developed a new conditional transgenic mouse showing that MLL-ENL, at an endogenous-like expression level, induces leukemic transformation selectively in LT-HSCs. To investigate the molecular mechanism of leukemic transformation in LT-HSCs conditionally expressing MLL-ENL, we preliminarily performed comprehensive gene expression profiling of CreER-transduced LT-HSCs and ST-HSCs using cDNA microarray analysis.
