hyperlipidemias/tyrosine

BACKGROUND Estrogen deficiency and increase in protein tyrosine phosphatase (PTPase) activity may be a key mechanism in postmenopausal dyslipidemia-induced vascular dysfunction and dementia. Thus, the present study has been designed to investigate the effect of biochanin A (BCA, a phytoestrogen) and

Postprandial dyslipidemia is recognized as an important complication of insulin-resistant states, and recent evidence implicates intestinal lipoprotein overproduction as a causative factor. The mechanisms linking intestinal lipoprotein overproduction and aberrant insulin signaling in intestinal

A 76-year-old man, diagnosed with chronic myeloid leukemia in 2010, had been on nilotinib for 7 years. He presented with right hemiparesis in September 2017. He had no history of hypertension, diabetes, hyperlipidemia, heart disease, or smoking. Brain MRI revealed a border-zone infarction of the

Protein tyrosine phosphatase 1B (PTP1B) is a widely confirmed target of the type 2 diabetes mellitus (T2DM) treatment. Herein, we reported a highly specific PTP1B inhibitor 2,2',3,3'-tetrabromo-4,4',5,5'-tetrahydroxydiphenylmethane (compound 1), which showed promising hypoglycemic activity in

OBJECTIVE To evaluate the lipid-regulating effects of extract from Ginkgo biloba leaves (EGB) using pharmacological methods and metabonomic profiling in a rat model of diet-induced hyperlipidemia. METHODS EGB was orally administered at a dose level of 40 mg/kg in both the EGB-prevention and

Endothelin-1 (ET-1) signaling mechanisms have been implicated in the pathogenesis of excess coronary artery disease in diabetic dyslipidemia. We hypothesized that in diabetic dyslipidemia ET-1-induced coronary smooth muscle calcium (Ca2+m) and tyrosine phosphorylation would be increased, and the

BACKGROUND Protein tyrosine phosphatase (PTP)- 1B, encoded by the PTPN1 gene, negatively regulates insulin signaling by dephosphorylating the phosphotyrosine residues of the insulin receptor kinase activation segment. Several rare single nucleotide polymorphisms (SNP) have been linked to diseases

Oxidative stress is believed to cause endothelial dysfunction, an early event and a hallmark in cardiovascular diseases (CVD) including hypertension, diabetes, and dyslipidemia. However, the targets for oxidative stress-mediated endothelial dysfunction in CVD have not been completely elucidated.

BACKGROUND Apolipoprotein CIII (apoCIII) is a component of some triglyceride-rich very-low-density and low-density lipoprotein and is elevated in dyslipidemia with insulin resistance and the metabolic syndrome. We previously reported that apoCIII directly activates proinflammatory and atherogenic

BACKGROUND Dityrosine, the modification of tyrosine residues, may contribute to metabolic disorders. This study was undertaken to investigate plasma dityrosine concentrations in patients with hyperlipidemia and to examine the correlation between dityrosine and lipid profiles. METHODS Fluorescence

There are several reports in literature implicating cholesterol metabolism in the pathogenesis of neuronal degenerations, oncogenesis, functional neuropsychiatric disorders and multiple sclerosis. Biosynthesis of cholesterol takes place by the isoprenoid pathway, which also produces digoxin, an

Obesity increases the incidence of cardiac arrhythmias and impairs wound healing. However, it is presently unknown whether a high-fat diet affects arrhythmic risk or wound healing before the onset of overt obesity or hyperlipidemia. After 8 wk of feeding a high-fat diet to adult female rats, a

Hypercholesterolemia and mesangial cell proliferation have been proposed to play a role in the progression of glomerulosclerosis in diabetic nephropathy and other renal diseases. Although LDL is mitogenic for and cytotoxic to mesangial cells, the effect of HDL on these cells is unknown. HDL
