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
The gastrointestinal tract of mammals is inhabited by hundreds of distinct species of commensal microorganisms that exist in a mutualistic relationship with the host. The process by which the commensal microbiota influence the host immune system is poorly understood. We show here that colonization of the small intestine of mice with a single commensal microbe, segmented filamentous bacterium (SFB), is sufficient to induce the appearance of CD4+ T helper cells that produce IL-17 and IL-22 (Th17 cells) in the lamina propria. SFB adhere tightly to the surface of epithelial cells in the terminal ileum of mice with Th17 cells but are absent from mice that have few Th17 cells. Colonization with SFB was correlated with increased expression of genes associated with inflammation, anti-microbial defenses, and tissue repair, and resulted in enhanced resistance to the intestinal pathogen Citrobacter rodentium. Control of Th17 cell differentiation by SFB may thus establish a balance between optimal host defense preparedness and potentially damaging T cell responses. Manipulation of this commensal-regulated pathway may provide new opportunities for enhancing mucosal immunity and treating autoimmune disease.

Description
Adipogenic differentiation and metabolic adaptation are initiated through transcriptional and epigenetic reprogramming. In particular, dynamic changes in histone modifications may play central roles in the rearrangement of gene expression patterns. LSD1 (KDM1) protein, encoded by aof2 gene, is a histone demethylase, which is involved in transcriptional regulation. Since the enzymatic activity of LSD1 is FAD (flavin adenine dinucleotide)-dependent, its effects on gene expression may be influenced by FAD availability.

Description
Adipogenic differentiation and metabolic adaptation are initiated through transcriptional and epigenetic reprogramming. In particular, dynamic changes in histone modifications may play central roles in the rearrangement of gene expression patterns. BHC80 protein, encoded by phf21a gene, is a part of LSD1 histone demethylase complex and is essential for the demethylation activity.
