Insulin and tumor necrosis factor alpha (TNF alpha) produce potent and opposing physiological signals in adipocytes. However, genes that are co-regulated by the hormone and cytokine during and after adipocyte differentiation have not been characterized. Using 3T3-L1 cells, we have studied the
NADPH-generating enzymes, glucose-6-phosphate dehydrogenase (G6PDH), and malic enzyme (ME) were studied in rat liver when necrosis and regeneration were induced by a single sublethal dose of thioacetamide (6.6 mmol/kg). Both enzyme activities decreased sharply at 12-24 hr of treatment and increased
This study was conducted to investigate the role of tumor necrosis factor-alpha (TNF-alpha) and interleukin-2 (IL-2) in inducing cancer cachexia, and the results were compared with those obtained from our previous study on Fisher 344 rats with methylcholanthrene-induced sarcoma. Three groups of male
The effects of multicytokine inducer, OK-432, on tumor-induced metabolic alterations were studied by assessing three key regulatory enzymes of gluconeogenesis, de novo fatty acid synthesis and the triglyceride clearance pathways. Two Klinish Einheit (KE) of OK-432 was subcutaneously injected on
The protective effects of Houttuynia cordata aqueous extract (HCAE) in mice consuming a high saturated fat diet (HFD) were examined. HCAE, at 0.5, 1, or 2%, was supplied in drinking water for 8 weeks. HCAE was rich in phenolic acids and flavonoids. HCAE intake at 1 and 2% decreased body weight,
We developed a strictly controlled serum-free culture system and tested the effects of adipogenic and antiadipogenic agents on the proliferation and(or) adipose conversion of porcine stromal-vascular cells. To avoid any interference with serum components, stromal-vascular cells were isolated,
Extracellular regulated kinases (ERKs) mediate the inhibitory effect of tumor necrosis factor alpha (TNF-alpha) on uncoupling protein-1 (UCP-1), but not on lipid accumulation. TNF-alpha-induced ERK-dependent peroxisome proliferator activator receptor gamma (PPAR gamma) phosphorylation could be
BACKGROUND
Neonatal Gram-negative sepsis is often characterized by a fulminant clinical course, compared to adults, resulting in higher morbidity and mortality. Genome-wide gene expression analysis can provide insights into the molecular alterations in sepsis.
OBJECTIVE
To evaluate in vitro
The acute-phase response (APR) leads to alterations in lipid metabolism and type II nuclear hormone receptors, which regulate lipid metabolism, are suppressed, in liver, heart, and kidney. Here, we examine the effect of the APR in adipose tissue. In mice, lipopolysaccharide produces a rapid, marked
Alleviative effects of s-allyl cysteine (SAC) and s-ethyl cysteine (SEC) upon methionine and choline deficient (MCD) diet-induced hepatotoxicity in mice were examined. SAC or SEC at 1g/L was added into drinking water for 7 weeks with MCD diet. MCD feeding significantly increased hepatic triglyceride
Triple negative breast cancer (TNBC) is characterized by poor prognosis and a DNA hypomethylation profile. Withaferin A (WA) is a plant derived steroidal lactone which holds promise as a therapeutic agent for treatment of breast cancer (BC). We determined genome-wide DNA methylation changes in
Based on the fact that traumatic brain injury is associated with mitochondrial dysfunction we aimed at localization of mitochondrial defect and attempted to correct it by thiamine.
Interventional controlled experimental animal study was used. Adult male Sprague-Dawley rats were subjected to lateral
The thiazolidinediones (TZDs) or 'glitazones' are a new class of oral antidiabetic drugs that improve metabolic control in patients with type 2 diabetes through the improvement of insulin sensitivity. TZDs exert their antidiabetic effects through a mechanism that involves activation of the gamma
Male outbred Sprague-Dawley rats were fed a choline-deficient diet containing 0.10% DL-ethionine for up to 30 weeks. Liver slices from rats killed 4, 6, 10, 14, 22 and 30 weeks after starting the treatment were histochemically analyzed for the following parameters: basophilia, expression of
