View SamplesTo elucidate the bioactive property of the dietary antioxidant curcumin, we examined tissue distribution and the gene expression- and lipidomic-profiles in epididymal white adipose tissue (eWAT) of the diet-induced obese mice. Dietary intake of curcumin (0.1% W/W) didnt affect the eWAT weight and the plasma lipid levels but reduced the levels of lipid peroxidation marker in eWAT. Curcumin was a slightly accumulated in eWAT and altered the gene expression associated with eukaryotic translation initiation factor 2 (EIF2) signaling. Curcumin suppressed the endoplasmic reticulum (ER) stress-related eIF2 phospholyration, the accumulation of macrophages and the expression of oxidative stress-sensitive transcription factor NF-B p65 and leptin, whereas anti-inflammatory effect wasnt enough to reduce the TNF- and IFN- levels. Lipidomic- and gene expression analysis suggests that curcumin reduced the contents of some diacylglyverols (DAGs) and DAG derived glycerophospholipids by suppressing the expressions of lipogenesis-related glycerol-3-phosphate acyltransferase 1 and lipolysis-related adipose triglyceride lipase.

View SamplesFrom preliminary experiments, HSP70 deficient MEF cells display moderate thermotolerance to a severe heatshock of 45.5 degrees after a mild preshock at 43 degrees, even in the absence of hsp70 protein. We would like to determine which genes in these cells are being activated to account for this thermotolerance.

View SamplesBcl6 germline deletion causes a prominent inflammatory disease, owing to over-expression of Th2 cytokines, and affects the properties of B cells prior to immunization. Therefore we established the B cell-specific Bcl6 deletion mice and analyze the gene expression of naive B cells under physiological conditions.

View SamplesNeutrophil abscess formation is critical in innate immunity against many pathogens. Here, the mechanism of neutrophil abscess formation was investigated using a mouse model of Staphylococcus aureus cutaneous infection. Gene expression analysis of S. aureus-infected skin revealed that induction of neutrophil recruitment genes was largely dependent upon IL-1beta/IL-1R activation. Unexpectedly, using IL 1beta reporter mice, neutrophils were identified as the primary source of IL-1beta at the site of infection. Furthermore, IL-1beta-producing neutrophils were necessary and sufficient for abscess formation and bacterial clearance. S. aureus-induced IL 1beta production by neutrophils required TLR2, NOD2, FPRs and the ASC/NLRP3 inflammasome. Taken together, IL-1beta and neutrophil abscess formation during an infection are functionally, spatially and temporally linked as a consequence of direct IL-1beta production by neutrophils.
Neutrophil-derived IL-1β is sufficient for abscess formation in immunity against Staphylococcus aureus in mice.
