Analysis of brown adipose tissues from glycerol kinase (GK) knockout mutants. GK is at the interface of fat and carbohydrate metabolism and has been implicated in insulin resistance and type 2 diabetes mellitus. Results provide insight into the role of GK in insulin resistance.

(Submitter supplied) Glycerol kinase (GK) is at the interface of fat and carbohydrate metabolism and has been implicated in insulin resistance and type 2 diabetes mellitus (T2DM). To define GK’s role in insulin resistance, we examined gene expression in brown adipose tissue in a glycerol kinase (Gyk) knockout (KO) mouse model using microarray analysis. Global gene expression profiles of KO mice were distinct from wild type (WT) with 668 genes that were differentially expressed. more...

(Submitter supplied) Glycerol kinase deficiency (GKD) is an X-linked inborn error of metabolism with metabolic and neurologic crises. Liver shows the highest level of glycerol kinase (GK) activity in humans and mice. Absence of genotype-phenotype correlations in patients with GKD indicate the involvement of modifier genes, including other network partners. To understand the molecular pathogenesis of GKD, we performed microarray analysis on liver mRNA from neonatal glycerol kinase (Gyk) knockout (KO) and wild type (WT) mice. more...

(Submitter supplied) Subcutaneous abdominal adipose tissue was obtained from female subjects undergoing plastic surgery in agreement with French laws on biomedical research. Stromal cells prepared from WAT were cultured for 13 days in a chemically defined medium. At day 13, 60–80% of cells were differentiated into lipid droplet-containing adipocytes. The cells were infected at a m.o.i. of 200 for 6 h. The day after infection, cells were treated with the following drugs at 1 µM unless otherwise indicated: rosiglitazone (BRL49653, Smith Kline and French, Harlow, UK) and 9-cis-RA (Sigma). more...

(Submitter supplied) Social stress is well known to be involved in the occurrence and exacerbation of mental illness, and also various life-style related diseases such as hyperinsulinemia, hyperglycemia, cardiovascular diseases and cancer. However, there is little information on tissue-specific gene expression in response to social stress, which reflects our daily life. Liver is one of the most important organs, owing to its biological functions such as energy metabolic homeostasis, metabolization and detoxification of endo- and exogenous substances. more...

(Submitter supplied) Recently, abnormalities in mitochondrial oxidative phosphorylation (OXPHOS) have been implicated in the pathogenesis of skeletal muscle insulin resistance in type 2 diabetes. In the present study, we hypothesized that decreased expression of OXPHOS genes could be of similar importance for insulin resistance in the polycystic ovary syndrome (PCOS). Using the HG-U133 Plus 2.0 expression array from Affymetrix, we analyzed gene expression in skeletal muscle from obese women with PCOS (n=16) and age- and body mass index-matched control women (n=13) metabolically characterized by euglycemic-hyperinsulinemic clamp and indirect calorimetry. more...

(Submitter supplied) d-serine is naturally present throughout the human body. It is also used as add-on therapy for treatment-refractory schizophrenia. d-Serine interacts with the strychnine-insensitive glycine binding site of NMDA receptor, and this interaction could lead to potentially toxic activity (i.e., excitotoxicity) in brain tissue. The transcriptomic changes that occur in the brain after d-serine exposure have not been fully explored. more...

(Submitter supplied) Prostaglandin F2 alpha (PGF2alpha) brings about regression of the bovine corpus luteum (CL). This luteolytic property of PGF2alpha is used in the beef and dairy cattle to synchronize estrus. A limitation of this protocol is an insensitivity of the early CL to luteolytic actions of PGF2alpha. The mechanisms underlying luteal sensitivity (LS) are poorly understood. The early CL has maximum number of PGF2alpha receptors; therefore differences in signaling events might be responsible for LS. more...
