BACKGROUND: Familial hypercholesterolemia is a genetic lipoprotein disorder characterized by elevated plasma low-density lipoprotein cholesterol level, (tendinous xanthomas, xanthelasmas, and premature arcus corneus) and early onset atherosclerotic cardiovascular disease. Familial hypercholesterolemia is caused by mutations in the low-density lipoprotein receptor, apolipoprotein B or proprotein convertase subtilisin/kexin type 9 genes. Rare mutations in low-density lipoprotein receptor adapter protein 1, APOE p...

Elevated levels of reactive oxygen species (ROS) are a hallmark of obesity. Peroxiredoxin 5 (Prx5), which is a cysteine-dependent peroxidase enzyme, has an intensive ROS scavenging activity because it is located in the cytosol and mitochondria. Therefore, we focused on the role of Prx5 in regulating mitochondrial ROS and adipogenesis. We demonstrated that Prx5 expression was upregulated during adipogenesis and Prx5 overexpression suppressed adipogenesis by regulating cytosolic and mitochondrial ROS generation...

The microtubule protein tubulin is a heterodimer comprising α/β subunits, in which each subunit features multiple isotypes in vertebrates. For example, seven α-tubulin and eight β-tubulin isotypes in the human tubulin gene family vary mostly in the length and primary sequence of the disordered anionic C-terminal tails (CTTs). The biological reason for such sequence diversity remains a topic of vigorous enquiry. Here, we demonstrate that it may be a key feature of tubulin's role in regulation of the permeability of the mitochondrial outer membrane voltage-dependent anion channel (VDAC)...

Bifenthrin (BF) is a synthetic pyrethroid pesticide widely used in several countries to manage insect pests on diverse agricultural crops. Growing evidence indicates that BF exposure is associated with an increased risk of developing neurodegenerative disorders. However, the mechanisms by which BF induces neurological and anxiety alterations in the frontal cortex and striatum are not well known. The present in vivo study was carried out to determine whether reactive oxygen species (ROS)-mediated oxidative stress (OS) and neuroinflammation are involved in such alterations...

AIMS: Decreased insulin clearance has been reported to be associated with insulin resistance-related disorders and incident type 2 diabetes. The aim of this study was to evaluate whether higher levels of uric acid (UA), a known risk factor of type 2 diabetes, are associated with a reduced insulin clearance. METHODS: 440 non-diabetic individuals were stratified in tertiles according to serum UA levels. Insulin clearance and skeletal muscle insulin sensitivity were assessed by euglycemic hyperinsulinemic clamp...

Genetically modified mice models suggest an important role for G-protein-coupled receptor kinase 5 (GRK5) in the pathophysiology of obesity and related disorders. We investigated whether single nucleotide polymorphisms (SNPs) in the gene encoding GRK5 affect cardiometabolic traits in humans. We genotyped 3 common SNPs in intron 1 (rs1980030, rs10466210, rs9325562) and one SNP in intron 3 (rs10886471) of GRK5 in 2332 subjects at risk for type 2 diabetes. Total- and visceral fat mass were measured by magnetic resonance (MR) tomography and liver fat content by 1 H-MR spectroscopy...

BACKGROUND Cholesteryl ester storage disease (CESD), also known as lysosomal acid lipase deficiency (LAL-D), is a rare autosomal-recessive inheritable lysosomal storage disease. Since 2015, a causal treatment with sebelipase alfa, which replaces the missing LAL enzyme, has been approved. We report a fatal course of LAL-D in a female patient. CASE REPORT In 1979, CESD was first diagnosed in a 13-year-old female with marked hepatomegaly. At that time, no specific treatment for CESD was available and the spontaneous course of the disease had to be awaited...

Objectives: Major depressive disorder is diagnosed on the basis of patient's self-reported experiences, behavior reported by relatives, and a mental status examination, and yet we do not have any reliable biomarker for this. Mood-regulating pathways are affected by oxidative injury to lipids and cortisol is released into the blood due to stimulation of corticotrophin receptors in the adrenal cortex. Here, we aimed to determine serum levels of malondialdehyde and cortisol in major depressive disorder patients and controls...

Over the recent years, a particular interest was shown towards understanding the roles of excessive hepatic fat accumulation and the development of obesity-related diseases. While hepatic triacylglycerol accumulation seems to be a response to the systemic increase of insulin release, fatty acid metabolites contribute to the progression of non-alcoholic fatty liver disease (NAFLD) to non-alcoholic steatohepatitis (NASH). It is widely accepted that NAFLD is a polygenic and multifactorial disease under the influence of critical behavioral factors such as overeating and sedentary lifestyles...

Diabetes mellitus (DM) is a chronic disease that can affect metabolism of glucose and other metabolites. In this study, the normal- and obese-diabetic rats were compared to understand the diabetes disorders of type 1 and 2 diabetes mellitus. This was done by evaluating their urine metabolites using proton nuclear magnetic resonance (1 H NMR)-based metabolomics and comparing with controls at different time points, considering the induction periods of obesity and diabetes. The biochemical parameters of the serum were also investigated...

BACKGROUND/AIMS: Systemic iron homeostasis is strictly governed in mammals; however, disordered iron metabolism (such as excess iron burden) is recognized as a risk factor for various types of diseases including AS (Atherosclerosis). The hepcidin-ferroportin axis plays the key role in regulation of iron homeostasis and modulation of this signaling could be a potential therapeutic strategy in the treatment of these diseases. TMP (Tetramethylpyrazine) has been reported to have therapeutical effect on AS...

Lipids are essential structural and functional components of cells. Little is known, however, about the evolution of lipid composition in different tissues. Here, we report a large-scale analysis of the lipidome evolution in six tissues of 32 species representing primates, rodents and bats. While changes in genes' sequence and expression accumulate proportionally to the phylogenetic distances, less than two percent of the lipidome evolves this way. Yet, lipids constituting this two percent cluster in specific functions shared among all tissues...
