Psoriasis is a common and chronic inflammatory skin disease that is complicated by gene-environment interactions. Although genomic, transcriptomic, and proteomic analyses have been performed to investigate the pathogenesis of psoriasis, the role of metabolites in psoriasis, particularly of lipids, remains unclear. Lipids not only comprise the bulk of the cellular membrane bilayers but also regulate a variety of biological processes such as cell proliferation, apoptosis, immunity, angiogenesis, and inflammation...

Chronic obstructive pulmonary disease (COPD) is a common, preventable and treatable condition that has a complex pathophysiology and an even more complex immunopathological process. The purpose of this review was to analyze COPD immunopathological aspects, which was addressed by undertaking a literature search for the most relevant documents indexed in the PubMed database over the last 10 years. Different conclusions could be drawn: in COPD immunopathology there are immune and non-immune inflammatory changes with oxidative stress imbalance, there are alterations in the protease/anti-protease ratio caused by direct and indirect genetic and epigenetic-environmental defects; COPD produces irreversible tissue damage and chronic inflammation with tissue repair alteration, which induces chronic obstruction of the airway, bronchitis and systemic damage...

Cardiovascular disease is the number one cause of death globally. Poor diet constitutes a key factor in the initiation and progression of cardiovascular disease and has become the leading risk factor for disability and death worldwide. Therefore, addressing suboptimal nutrition is of key prognostic relevance in primary and secondary prevention of metabolic vascular syndrome.Metabolic vascular syndrome is a multidimensional network of acquired cardiometabolic risk factors closely related to insulin resistance (IR) and concomitant hyperinsulinemia...

Validamycin A (Val-A) is produced by Streptomyces as a secondary metabolite with wide agricultural applications of controlling rice sheath blight, false smut and damping-off diseases. The effect of alkaline pH shock on enhancing Val-A production and its mechanism were investigated. A higher yield of Val-A was achieved by NaOH shock once or several times together with faster protein synthesis and sugar consumption and alkaline pH shock can increase Val-A production by 27.43%. Transcription of genes related to amino acid metabolism, carbon metabolism and electron respiratory chain was significantly up-regulated, accompanied by the substantial increase of respiratory activity and glutamate concentration...

REVIEW
Ira Tabas, Andrew H Lichtman
Atherosclerosis is an arterial disease process characterized by the focal subendothelial accumulation of apolipoprotein-B-containing lipoproteins, immune and vascular wall cells, and extracellular matrix. The lipoproteins acquire features of damage-associated molecular patterns and trigger first an innate immune response, dominated by monocyte-macrophages, and then an adaptive immune response. These inflammatory responses often become chronic and non-resolving and can lead to arterial damage and thrombosis-induced organ infarction...

Controllable transgene expression systems are indispensable tools for the production of animal models of disease to investigate protein functions at defined periods. However, in non-human primates that share genetic, physiological, and morphological similarities with humans, genetic modification techniques have not been well established; therefore, the establishment of novel transgenic models with controllable transgene expression systems will be valuable tools to understand pathological mechanism of human disease...

PURPOSE OF REVIEW: Bile acids act as activating signals of endogenous renal receptors: the nuclear receptor farnesoid X receptor (FXR) and the membrane-bound G protein-coupled bile acid receptor 1 (GPBAR1, also known as TGR5). In recent years, bile acids have emerged as important for renal pathophysiology by activating FXR and TGR5 and transcription factors relevant for lipid, cholesterol and carbohydrate metabolism, as well as genes involved in inflammation and renal fibrosis. RECENT FINDINGS: Activation of bile acid receptors has a promising therapeutic potential in prevention of diabetic nephropathy and obesity-induced renal damage, as well as in nephrosclerosis...

PURPOSE OF REVIEW: The renin-angiotensin system (RAS) is a pivotal player in the physiology and pathophysiology of cardiovascular and renal systems. Discovery of angiotensin-converting enzyme 2 (ACE2), capable of cleaving RAS effector peptide angiotensin (Ang) II into biologically active Ang-(1-7), has increased the complexity of our knowledge of the RAS. ACE2 expression is abundant in the kidney and is thought to provide protection against injury. This review emphasizes current experimental and clinical findings that examine ACE2 in the context of kidney injury and its potential therapeutic impact for treatment of kidney disease...

The article of D'Ovidio et al.(1) in the current issue of European Journal of Neurology is an important addition to the growing body of evidence supporting a disease-modifying effect of metabolic disorders in neurodegenerative diseases (NDDs). Eight years ago, we first showed a protective effect of type 2 diabetes mellitus (T2DM) in ALS. Using a very large clinical cohort (n=2,371), we found that pre-morbid T2DM was associated with a reduced risk for ALS and a 4 year delay in onset.(2) Since then, a number of studies have independently confirmed a protective effect of T2DM in ALS...

Use of active forms of vitamin D is advocated in CKD patients for treatment of mineral bone disease because of the presumption that native forms of vitamin D would not undergo significant activation to calcitriol, the most active biological form of vitamin D. We present secondary analysis looking at bone turnover in subjects who completed the randomized, double blind, placebo controlled trial investigating the effect of cholecalciferol supplementation on vascular function in non-diabetic CKD stage G3-4 and vitamin D ≤20ng/ml [CTRI/2013/05/003648]...

BACKGROUND: crAssphage is a novel and by far the most abundant bacteriophage in human gut. This bacteriophage might modulate gut microbiota balance so as to be involved in some diseases like obesity, diabetes, metabolic disorders, hypertension, and cancer. Therefore, a rapid and reliable detection and quantification method for crAssphage is essential for studying its molecular epidemiology and pathogenicity in human diseases. MATERIALS AND METHODS: The primers-probes set for the quantitative real-time PCR assay was designed based on the DNA polymerase gene (ORF00018) of crAssphage...

Renal epithelial cells are exposed to mechanical forces due to flow-induced shear stress within the nephrons. Shear stress is altered in renal diseases caused by tubular dilation, obstruction and hyperfiltration, which occur to compensate for lost nephrons. Fundamental in regulation of shear stress are primary cilia and other mechano-sensors, and defects in cilia formation and function have profound effects on development and physiology of kidneys and other organs. We applied RNA sequencing to get a comprehensive overview of fluid-shear regulated genes and pathways in renal epithelial cells...

Metabolic acidosis is highly prevalent in hemodialysis patients. The disorder is associated with increased mortality and its deleterious effects are already present in the predialysis phase of chronic kidney disease. Metabolic acidosis has been linked to progression of chronic kidney disease, changes in protein and glucose metabolism, bone and muscle disorders and cardiovascular disease. At present, the control of metabolic acidosis in hemodialysis is mainly focused on the supply of bicarbonate during dialysis session, but further studies are needed to set the optimum target serum bicarbonate and the best concentration of the bicarbonate dialysate...
