- Affymetrix Rice Genome Array (rice)
Description
Cytokinins (CKs) are a class of plant hormones that regulate many aspects of growth and development, including cell division, apical dominance, leaf senescence, nutrient signaling, and shoot differentiation. In the past decade, substantial progress has been made in understanding CK biosynthesis, metabolism and signal transduction. Much of this knowledge is based on research in Arabidopsis, a dicotyledonous model plant. Although cytokinin plays an important role for growth and development in the Gramineae, our knowledge of cytokinin responsive genes in monocotyledonous species is very limited compared to Arabidopsis. The search for genes whose expression is modified by CK has yielded a number of valuable tools that have been used to understand CK signaling and the complex developmental processes under control of this hormone. We tried to identify rice genes regulated by CK using an Affymetrix rice genome array.

In the past decade, substantial progress has been made in understanding CK biosynthesis, metabolism and signal transduction. Much of this knowledge is based on research in Arabidopsis, a dicotyledonous model plant. The current model of the CK signaling pathway is a multi-step His-Asp phosphorelay system. Some of the cytokinin-inducible response regulators are thought to act as negative regulators of CK signaling. We tried to identify rice genes regulated by CK-inducible response regulator using an Affymetrix rice genome array and transgenic rice that over-express OsRR6.

Description
Gibberellins control a wide range of aspects of plant growth and development. Although a series of mutant of the signaling pathway has been identified, the global regulatory network underlying gibberellin signal transduction has not been revealed. To address this issue, we performed microarray analysis with rice gibberellin signaling mutants, gid1, gid2, slr, and the parental cultivar Taichung 65.

Description
Dual oxidases play a role in innate host defense at barrier epithelia. We examined the effect of loss of dual oxidase function (duoxa-/-) on gene expression in the mouse terminal ileum at homeostasis. To control for cage/litter effects, duoxa-/- were cohoused with wild type littermate controls.

Description
Gut dysbiosis is closely involved in the pathogenesis of inflammatory bowel disease (IBD). However, it remains unclear whether IBD-associated gut dysbiosis plays a primary role in disease manifestation or is merely secondary to intestinal inflammation. Here, we established a humanized gnotobiotic (hGB) mouse system to assess the functional role of gut dysbiosis associated with two types of IBD - Crohn's disease (CD) and ulcerative colitis (UC).

Description
Despite accepted health benefits of dietary fiber, little is known about the mechanisms by which fiber deprivation impacts the gut microbiota and alters disease risk. Using a gnotobiotic model, in which mice were colonized with a synthetic human gut microbiota, we elucidated the functional interactions between dietary fiber, the gut microbiota and the colonic mucus barrier, which serves as a primary defence against pathogens. We show that during chronic or intermittent dietary fiber deficiency, the gut microbiota resorts to host-secreted mucus glycoproteins as a nutrient source, leading to erosion of the colonic mucus barrier. Dietary fiber deprivation promoted greater epithelial access and lethal colitis by the mucosal pathogen, Citrobacter rodentium, but only in the presence of a fiber-deprived microbiota that is pushed to degrade the mucus layer. Our work reveals intricate pathways linking diet, gut microbiome and intestinal barrier dysfunction, which could be exploited to improve health using dietary therapeutics.

Description
TET2 is an enzyme for converting methylcytosine (mC) to hydorxymethylcytosine (hmC) and its mutations have been frequently found in myeloid malignancies and T-cell lymphoma in humans. We analyzed Tet2 gene trap mice and found that homozygous mice developed T-cell lymphoma with follicular helper T-cell-like features.
