Project description:The role of murine peroxisome proliferator-activated receptor-delta (PPARd) in mammary tumorigenesis was assessed. Microarrays were used to analyse global gene expression to determine changes in MMTV-PPARd transgenic mice versus wild-type mice and the effect of GW501516.

Project description:Investigation of whole genome gene expression level changes in GW501516 (a Ppard ligand) or Il-4 treated Ppard-overexpressing RAW 264.7 macrophages as compared to vehicle. Alternative activation of adipose tissue resident macrophages inhibits obesity-induced metabolic inflammation. In the current study we profile genes regulated by two M2 inducers, Il-4 or Ppard agonists and find that alternative activation promotes the cell survival program, while inhibiting that of inflammation-related cell death.

Project description:The role of murine peroxisome proliferator-activated receptor-delta (PPARd) in mammary tumorigenesis was assessed. Microarrays were used to analyse global gene expression to determine changes in MMTV-PPARd transgenic mice versus wild-type mice and the effect of GW501516. RNA was isolated (RNeasy Mini Kit, Qiagen) from mammary gland tissue of transgenic and wild-type mice maintained on normal rodent chow or 0.005% GW501516

Project description:The PPAR (Peroxisome proliferator-activated receptor) family of nuclear receptors has three members: PPARg, PPARa and PPARd. Although they share similar structures, their biological functions are distinct. PPARg controls lipid storage and adipogenesis, while PPARd is associated with fat burning. The highly specific synthetic ligand for PPARd, GW501516, is a promising drug candidate for obesity and diabetes. Here we use Affymetrix microarray to analyze gene expression profile in mouse embryo fibroblasts treated with 100 nM GW501516 for 0, 2, 8 and 24 hours. These data may provide new clues into the molecular mechanism by which GW501516 ameliorates obesity and diabetes.

Project description:The formation of antigen-specific memory CD8+ T cells is one of the most important features of the adaptative immune system, allowing the establishment of long-term protection against secondary infections. Although emerging evidence suggests that metabolic reprogramming is crucial for memory T cell differentiation and survival, the underlying mechanisms that drive metabolic rewiring needed for memory T cells remain unclear. Here, we found that the nuclear receptor peroxisome proliferator-activated receptor-beta/delta (PPARβ/δ) was upregulated to instruct the metabolic reprogramming, including downregulation of aerobic glycolysis and the promotion of oxidative metabolism and fatty acid oxidation, that occurs during the transition toward the establishment of central memory CD8+ T cells. Mechanistically, the exposure to interleukin-15 (IL-15) and expression of T cell factor 1 (TCF1) could coordinately activated the PPARβ/δ pathway during acute viral infection and chronic antigen exposure contexts, counteracting apoptosis induced by antigen clearance and metabolic stress. Together, our work indicates that PPARβ/δ is a master metabolic regulator orchestrating the metabolic reprogramming required for the establishment of a metabolic profile favorable for T cells longevity.

Wild type mouse embryonic fibroblasts (MEFs) stably infected with retroviruses MSCVpuro expressing PPARd were plated at 0.5 million per 10 cm dish. After overnight incubation, cells were treated with 100nM GW501516 for 0h, 2h, 8h and 48h. Cells were collected at subconfluent condition. Total RNAs were sequentially purified with Trizol (Invitrogen) and RNeasy kit (Qiagen) and analyzed in triplicate on Mouse Genome 430 2.0 Array (Affymetrix) at NIDDK Microarray Core Facility following standard protocols.

Project description:Alcoholic liver disease is a pathological condition caused by over-consumption of alcohol. Due to the high prevalence of morbidity and mortality associated with this disease, there remains a need to elucidate the molecular mechanisms underlying the etiology to develop new treatments. Since peroxisome proliferator-activated receptor-β/δ (PPARβ/δ) modulates ethanol-induced hepatic effects, the present study examined alterations in gene expression that may contribute to this disease.
