The 2015 Dietary Guidelines for Americans recommend limiting the intake of saturated fatty acids (SFAs) to <10% of energy/d and replacing dietary SFAs with unsaturated fatty acids. A Presidential Advisory from the American Heart Association recently released its evaluation of the relation between dietary fats and cardiovascular disease (CVD), and also recommended a shift from SFAs to unsaturated fatty acids, especially polyunsaturated fatty acids (PUFAs), in conjunction with a healthy dietary pattern. However, the suggestion to increase the intake of PUFAs in general, and omega-6 (n-6) PUFAs in particular, continues to be controversial...

Peroxisomes are central to eukaryotic metabolism, including the oxidation of fatty acids-which subsequently provide an important source of metabolic energy-and in the biosynthesis of cholesterol and plasmalogens. However, the presence and nature of peroxisomes in the parasitic apicomplexan protozoa remains controversial. A survey of the available genomes revealed that genes encoding peroxisome biogenesis factors, so-called peroxins (Pex), are only present in a subset of these parasites, the coccidia. The basic principle of peroxisomal protein import is evolutionarily conserved, proteins harbouring a peroxisomal-targeting signal 1 (PTS1) interact in the cytosol with the shuttling receptor Pex5 and are then imported into the peroxisome via the membrane-bound protein complex formed by Pex13 and Pex14...

Colorectal cancer (CRC) is the third most prevalent neoplasm worldwide and fourth most frequent reason of cancer-related death throughout the world. About 70% of malignant tumors are related to lifestyle and environmental factors, and better knowledge of their significance might reduce the prevalence of CRC. The cyclooxygenase-2 (COX-2) inhibitory and other direct and indirect pathways of aspirin are translated to inhibition proliferation and enhanced apoptosis of cancer cells. Many studies showed the benefits of aspirin in reducing the risk of CRC development, cancer-related mortality and adenoma prevalence rate in general population, but not in high risk populations...

There is an escalating debate over the value and validity of memory-based dietary assessment methods (M-BMs). Proponents argue that despite limitations, M-BMs such as food frequency questionnaires (FFQs), provide valid and valuable information about consumed foods and beverages, and therefore can be used to assess diet-disease relations and inform public policy. In fact, over the past 60 years thousands of research reports using these methods were published and used to populate the United States Department of Agriculture's National Evidence Library, inform public policy, and establish the Dietary Guidelines for Americans...

Epidemiologic studies are controversial concerning the roles played by cholesterol in cancer risk and development, possibly as it is not cholesterol per se that is pathologic in cancers. Indeed, recent data reveal that the cholesterol metabolism in cancer cells can generate endogenous oncopromoter metabolites at higher levels compared with normal tissues and/or can be deregulated in the production of endogenous oncosuppressor metabolites in an opposite way. These metabolites are oxysterols, which are cholesterol oxygenation products generated by enzymatic and/or autoxidation processes...

To transfer the viral genome into the host cell cytoplasm, internalized influenza A virus (IAV) particles depend on the fusion of the IAV envelope with host endosomal membranes. The antiviral host interferon (IFN) response includes the upregulation of interferon-induced transmembrane protein 3 (IFITM3), which inhibits the release of the viral content into the cytosol. Although IFITM3 induction occurs concomitantly with late endosomal/lysosomal (LE/L) cholesterol accumulation, the functional significance of this process is not well understood...

Objective: MicroRNA (miR)-122 is highly expressed in the liver, where it has been implicated as a regulator of fatty-acid metabolism. A recent study reported that miR-122 plays a role in pathogenesis of atherosclerosis; however, whether it connects with severity of atherosclerotic lesion is still controversial. We therefore investigated the association between miR-122 expression and presence and severity of coronary atherosclerotic plaque. Methods: During January-November 2017, we included 300 patients with coronary heart disease (CHD) and 100 subjects as the control group...

Nonalcoholic fatty liver disease (NAFLD) is strongly associated with insulin resistance. The peroxisome proliferator-activated receptor (PPAR) activators, thiazolidinediones, (TZDs), are insulin sensitizers used as a treatment for NAFLD. However, TZDs are a controversial treatment for NAFLD because of conflicting results regarding hepatic steatosis and fibrosis. To evaluate a possible effective drug for treatment of NAFLD, we investigated the effects of a newly developed TZD, lobeglitazone, with an emphasis on hepatic lipid metabolism...

PURPOSE OF REVIEW: Current data suggest that proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors may affect many metabolic pathways beyond lowering LDL cholesterol. The aim of the present manuscript is to present these so-called pleiotropic effects of PCSK9 inhibitors. RECENT FINDINGS: PCSK9 may affect the activity of other receptors beyond LDL receptors (LDLR), such as cluster of differentiation 36 (CD36), very-low-density-lipoprotein (VLDL) receptors, apolipoprotein (Apo) E receptors, LDLR-related protein 1 (LRP-1) and ATP-Binding Cassette Transporter (ABCA1)...

During their metabolism, all lipoproteins undergo endocytosis, either to be degraded intracellularly, for example in hepatocytes or macrophages, or to be re-secreted, for example in the course of transcytosis by endothelial cells. Moreover, there are several examples of internalized lipoproteins sequestered intracellularly, possibly to exert intracellular functions, for example the cytolysis of trypanosoma. Endocytosis and the subsequent intracellular itinerary of lipoproteins hence are key areas for understanding the regulation of plasma lipid levels as well as the biological functions of lipoproteins...

PURPOSE: Previous studies have shown that serum uric acid levels and inflammation are associated with bone mineral density. Gout, a disease characterized by hyperuricemia and inflammation, contributes to the risk of osteoporotic fractures. However, this association is controversial. Therefore, this study investigated whether gout in older people (age > 55 years) is associated with osteoporotic fracture risk. METHODS: This population-based, cross-sectional study included 2674 participants (147 cases of gout and 388 fractures)...
