Description
IL-1R-associated kinases (IRAKs) participate in Toll-like receptor (TLR) signal transduction. MALP-2 is a TLR2 ligand, and stimulation of macrophages with MALP-2 activates expression of various genes including proinflammatory cytokines.
Publication Title

Description
Polarization of macrophages to M1 or M2 cells is important for mounting responses against bacterial and helminth infection respectively. Jumonji domain containing 3 (JMJD3), a histone 3 K27 demethylase, has been implicated in the activation of macrophages. Here we show that JMJD3 is essential for M2 macrophage polarization to helminth infection and chitin, though JMJD3 is dispensable for M1 responses. Furthermore, Jmjd3 is critical for proper bone marrow macrophage differentiation in a demethylase activity-dependent manner. Jmjd3 deficiency affected trimethylation of H3K27 in only a limited numbers of genes. Among them, we identified Irf4 as the target transcription factor critical for controlling M2 macrophage polarization. Collectively, these results show that JMJD3-mediated H3K27 demethylation is critical for regulating M2 macrophage development leading to anti-helminth host responses.

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
The aim of this study was to examine the role of indigenous lactobacilli in the physiological development of the stomach in mice using microarray analysis. In lactobacilli-associated gnotobiotic mice, an increased expression of the genes related to the muscle system development, such as nebulin and troponin, was observed. On the other hand, the expression of the gastrin gene dramatically decreased. A microarray analysis of the stomachs infected with H. pylori also showed both the up-regulation of muscle cell genes and the down-regulation of gastrin genes.

Description
Aquaporin-11 (AQP11), a new member of the aquaporin family, is localized in the endoplasmic reticulum (ER). Aqp11/ mice neonatally suffer from polycystic kidneys derived from the proximal tubule. Its onset is proceeded by the vacuolization of ER. However, the mechanism for the formation of vacuoles and the development of cysts remain to be clarified. Here, we show that Aqp11/ mice and polycystic kidney disease animals share a common pathogenic mechanism of cyst formation.

Description
During embryogenesis, many key transcription factors are used repeatedly, achieving different outcomes depending on cell type and developmental stage. The epigenetic modification of the genome functions as a memory of a cells developmental history, and it has been proposed that such modification shapes the cellular response to transcription factors. To investigate the role of DNA methylation in the response to transcription factor Gata4, we examined expression profiles of Dnmt3a-/-Dnmt3b-/- ES cell-derived mesoderm cells cultured for 4 days with or without Gata4 activation, as well as the wild-type counterparts, using Affymetrix microarrays.

DNA methylation restricts lineage-specific functions of transcription factor Gata4 during embryonic stem cell differentiation.

Description
Cultured cancer cells exhibit substantial phenotypic heterogeneity when measured in a variety of ways such as sensitivity to drugs or the capacity to grow under various conditions. Among these, the ability to exhibit anchorage-independent cell growth (colony forming capacity in semisolid media) has been considered to be fundamental in cancer biology because it has been connected with tumor cell aggressiveness in vivo such as tumorigenic and metastatic potentials, and also utilized as a marker for in vitro transformation. Although multiple genetic factors for anchorage-independence have been identified, the molecular basis for this capacity is still largely unknown. To investigate the molecular mechanisms underlying anchorage-independent cell growth, we have used genome-wide DNA microarray studies to develop an expression signature associated with this phenotype. Using this signature, we identify a program of activated mitochondrial biogenesis associated with the phenotype of anchorage-independent growth and importantly, we demonstrate that this phenotype predicts potential for metastasis in primary breast and lung tumors.
