Human plasma phospholipid transfer protein (PLTP) circulates bound to high density lipoprotein (HDL) and mediates both net transfer and exchange of phospholipids between different lipoproteins. However, its overall function in lipoprotein metabolism is unknown. To assess the effects of increased plasma levels of PLTP, human PLTP transgenic mice were established using the human PLTP gene driven ...

Serum apolipoprotein (apo)AI and -B have been shown to be associated with diabetic retinopathy, but the underlying mechanisms are unclear. We investigated whether apoAI and apoB levels are associated with measures of systemic and retinal microvascular function in patients with diabetes. We recruited 224 diabetic patients (85 type 1 and 139 type 2) and assessed serum lipids and lipoproteins from...

The apolipoprotein AI (apoAI) promoter/enhancer contains multiple cis -acting elements on which a variety of hepatocyte-enriched and ubiquitous transcription factors function synergistically to regulate liver-specific transcription. Adenovirus E1A proteins repress tissue-specific gene expression and disrupt the differentiated state in a variety of cell types. In this study expression of E1A 12S...

The aim of the study was the assessment of the impact of supplementation with folic acid on the concentration of homocysteine, total cholesterol (TC), HDL- and LDL-cholesterol, triglycerides (TG), apoprotein AI (apoAI) and apoprotein B (apoB) in patients suffering from primary hypertension. The examined group comprised 42 patients suffering from primary hypertension. All examined patients under...

Background: In the era of intensity-modulated radiotherapy (IMRT), distant metastasis remains the major cause of death from nasopharyngeal carcinoma (NPC). This study aimed to evaluate the clinical value of pretreatment serum lipid profiles in predicting clinical outcome of NPC. Methodology / Principal Findings: A total of 1927 consecutive patients who had untreated NPC and completed radical IM...

Since the original description of the gene encoding apolipoprotein AI (apoAI) considerable progress has been made in identifying the regulatory regions and corresponding transcription factors that regulate its transcription in liver and intestinal cells. Nuclear receptors (in particular HNF-4) have emerged as the dominant (although by no means the exclusive) transcriptional activators that driv...

An initial step in reverse cholesterol transport is the movement of unesterified cholesterol from peripheral cells to high-density lipoproteins (HDLs). This transfer usually occurs in extracellular spaces, such as the subendothelial space of a vessel wall, and is promoted by the interaction of lipid-free or lipid-poor apolipoprotein (apo)AI with ATP binding cassette A1 cellular transporters on ...

Obesity is a strong cardiometabolic (CM) risk factor in children. We tested potential CM risk in obese/overweight children and the effect of an intensive lifestyle intervention using newer CM markers: atherogenic index of plasma AIP [Log(TG/HDL-C)], apoB/apoAI ratio and a marker of insulin resistance HOMA-IR. The participants (194 girls, 115 boys, average age 13) were enrolled in an intensive, ...

Apolipoprotein A-I (apoA-I) is the main protein of high-density lipoprotein (HDL) and a principal mediator of the reverse cholesterol transfer pathway. Variants of apoA-I have been shown to be associated with hereditary amyloidosis. We previously characterized the G26R and L178H variants that both possess decreased stability and increased fibril formation propensity. Here we investigate the Mil...
