OBJECTIVE To examine the impact of low-density lipoprotein (LDL), an established mediator of atherosclerosis, on the transcription factor cAMP-response element-binding protein (CREB), which is a regulator of vascular smooth muscle cell (VSMC) quiescence. METHODS AND RESULTS VSMC CREB content is diminished in rodent models of diabetes and pulmonary hypertension. We examined aortic CREB content...
Previous studies show that exercise training and caloric restriction improve cardiac function in obesity. However, the molecular mechanisms underlying this effect on cardiac function remain unknown. Thus, we studied the effect of exercise training and/or caloric restriction on cardiac function and Ca handling protein expression in obese rats. To accomplish this goal, male rats fed with a high-f...
Previous studies show that exercise training and caloric restriction improve cardiac function in obesity. However, the molecular mechanisms underlying this effect on cardiac function remain unknown. Thus, we studied the effect of exercise training and/or caloric restriction on cardiac function and Ca(2+) handling protein expression in obese rats. To accomplish this goal, male rats fed with a hi...
Thioredoxin-interacting protein (Txnip) inhibits thioredoxin NADPH-dependent reduction of protein disulfides. Total Txnip knockout (TKO) mice adapted inappropriately to prolonged fasting by shifting fuel dependence of skeletal muscle and heart from fat and ketone bodies to glucose. TKO mice exhibited increased Akt signaling, insulin sensitivity, and glycolysis in oxidative tissues (skeletal mus...
Hypercholesterolemia is a major risk factor for atherosclerosis. It also is associated with platelet hyperactivity, which increases morbidity and mortality from cardiovascular disease. However, the mechanisms by which hypercholesterolemia produces a procoagulant state remain undefined. Atherosclerosis is associated with accumulation of oxidized lipoproteins within atherosclerotic lesions. Small...
During inflammation, serum amyloid A (SAA) protein increases up to 1000-fold and can become a major component of high-density lipoprotein (HDL). We have identified a new apolipoprotein molecule (SAA5) as a distinct member of the SAA family. It differs from the inflammatory isotypes (SAA1, SAA2, and SAA3) not only in structure but in the fact that it is constitutive on normal HDL where it accoun...
Granulocyte-colony stimulating factor (G-CSF) has been reported to improve the function of infarcted heart, but its effects on atherosclerosis are unclear. Here we examined the effects and the potential mechanisms in the high-fat diet rabbit model. Six-month-old male New Zealand white rabbits, fed a high-cholesterol diet or a normal diet for 10 weeks, were treated with vehicle or G-CSF. G-CSF i...
Alcoholic liver disease (ALD) spans a spectrum of liver pathology, including fatty liver, alcoholic steatohepatitis, and cirrhosis. Accumulating evidence suggests that dietary factors, including dietary fat, as well as alcohol, play critical roles in the pathogenesis of ALD. The protective effects of dietary saturated fat (SF) and deleterious effects of dietary unsaturated fat (USF) on alcohol-...
The trafficking of dietary fat was assessed in obesity-prone (OP) and obesity-resistant (OR) male and female rats. Test meals containing [1-(14)C]palmitate were delivered through gastric feeding tubes while rats consumed a high-carbohydrate diet (HCD) or after 5 days of a high-fat diet (HFD). Over the subsequent 24 h, the appearance of (14)C was followed in the GI tract, skeletal muscles (SM), ...
Role of persimmon (Diospyros kaki, Thunb ‘Saijo’) peel was investigated on developing atherosclerosis in low-density lipoprotein receptor (LDLR)-deficient mice with emphasis on lipid metabolism, physio-biological oxidation, production of related atherogenic autoantigens, and production of anti-atherogenic natural antibodies. Male LDLRdeficient mice were fed high fat diet or high fat diet supple...
