The prevalence of non-alcoholic fatty liver disease (NAFLD) has sharply increased over the past several decades in Korea. In most cases of NAFLD, metabolic stress and cellular apoptosis are often driven by metabolic abnormality, eventually leading to inflammation and fibrosis . Along with a dramatic surge in the obesity epidemic, 10-20% of NAFLD patients ultimately progress to non-alcoholic steatohepatitis (NASH), a precursor to cirrhosis and hepatocellular carcinoma, as well as multi-organ systemic diseases...

Non-alcoholic fatty liver disease (NAFLD) may be one of the important causes of cryptogenic hepatocellular carcinoma (HCC). NAFLD-related HCCs (NAFLD-HCCs) have the following clinical features: high body mass index, deranged lipid profiles, diabetes mellitus, hypertension, and metabolic syndrome. Among them, obesity, diabetes mellitus, and high Fe contents in the liver are risk factors of developing HCC in patients with NAFLD. Inflammatory cytokines, adipokines, insulin like growth factor-I, and lipotoxicity are intermingled and may cross react with each other to develop HCC...

Understanding the pathogenesis of non-alcoholic steatohepatitis (NASH) and its fibrosis progression is still evolving. Nonetheless, current evidence suggests that mechanisms involved are very complex parallel processes with multiple metabolic factors. Lipotoxicity related with excess saturated free fatty acids, obesity, and insulin resistance acts as the central driver of cellular injury via oxidative stress. Hepatocyte apoptosis and/or senescence are also contribute to the activation of inflammasome via various intra- and inter-cellular signaling mechanisms that lead to fibrosis...

Non-alcoholic fatty liver disease (NAFLD) includes a wide spectrum of diseases that range from simple steatosis to non-alcoholic steatohepatitis (NASH) and cirrhosis. In addition, the burden of NAFLD is rapidly growing. Previously, NAFLD was regarded as a hepatic manifestation of metabolic syndrome, which is a traditional cardiovascular disease (CVD) risk factor. However, there has been an increasing evidence that suggest NAFLD to be an independent risk factor of CVD. Therefore, currently, NAFLD should be reconsidered as not only a simple manifestation of metabolic syndrome, but also a systemic disease that contribute to CVD...

Nutritional effects on cancer occurrence and on treatment outcome in cancer patients may depend on food preferences and on the quantity of foods supplied. However, it has been difficult to reliably show beneficial effects of specific dietary concepts on cancer incidence. On the other hand, obesity as a result of chronic overfeeding has been linked firmly to an increased risk of a number of cancers as well as on cancer recurrence after treatment. Metabolic consequences of obesity and other components of the metabolic syndrome may be responsible for inducing and/or promoting cancer growth and should be antagonized by regular moderate physical activity in healthy subjects and in cancer survivors...

Wei Huang, Nelson J Chao
Graft-versus-host disease (GVHD) is a major complication of allogeneic hematopoietic stem cell transplantation (AHSCT) and the major cause of nonrelapse morbidity and mortality of AHSCT. In AHSCT, donor T cells facilitate hematopoietic stem cell (HSC) engraftment, contribute to anti-infection immunity, and mediate graft-versus-leukemia (GVL) responses. However, activated alloreactive T cells also attack recipient cells in vital organs, leading to GVHD. Different T-cell subsets, including naïve T (TN) cells, memory T (TM) cells, and regulatory T (Treg) cells mediate different forms of GVHD and GVL; TN cells mediate severe GVHD, whereas TM cells do not cause GVHD, but preserve T-cell function including GVL...

The elevated systemic levels of cytokines in rheumatoid arthritis (RA) can change the expression of metabolic enzymes and transporters. Given that statins are lipid-lowering agents frequently used in RA patients with concurrent cardiovascular diseases, the objective of the present study was to investigate the impacts of RA on the pharmacokinetics of statins of different disposition properties in rats with collagen-induced arthritis (CIA). The expression of metabolic enzymes and transporters in tissues of CIA rats were analyzed by RT-qPCR...

Mutations in the human genes PRESENILIN1 (PSEN1), PRESENILIN2 (PSEN2) and AMYLOID BETA A4 PRECURSOR PROTEIN (APP) have been identified in familial Alzheimer's disease (AD). The length of mitochondrion-endoplasmic reticulum (M-ER) appositions is increased in Psen1-/-/Psen2-/- double knockout murine embryonic fibroblasts and in fibroblasts from AD-affected individuals. Development of an easily accessible, genetically manipulable, in vivo system for studying M-ER appositions would be valuable so we attempted to manipulate M-ER apposition length in zebrafish (Danio rerio) embryos...

Anorexia nervosa (AN) is a psychiatric disease with devastating physical consequences, with a pathophysiological mechanism still to be elucidated. Metagenomic studies on anorexia nervosa have revealed profound gut microbiome perturbations as a possible environmental factor involved in the disease. In this study we performed a comprehensive analysis integrating data on gut microbiota with clinical, anthropometric and psychological traits to gain new insight in the pathophysiology of AN. Fifteen AN women were compared with fifteen age-, sex- and ethnicity-matched healthy controls...

Currently available studies have suggested that a number of exosome-encapsulated microRNAs (miRNAs) are recognized as stable biomarkers for cancers. However, little is known about the effect of exosomal miRNAs on colorectal cancer (CRC). The aim of study is to identify specific miRNAs in serum exosomes, which may serve as potential diagnostic and prognostic biomarkers and therapeutic targets for CRC. Microarray analyses of miRNAs in serum exosomes from 3 primary CRC patients and 3 healthy controls were performed...

Quantification of circulating tumor cells (CTCs) in blood samples from cancer patients is a non-invasive approach to monitoring the status of the disease. Most of the methods proposed in the recent years are phenomenological and rely on the use of antibodies labelled with fluorophores, magnetic particles, or immobilized on surfaces to capture the CTCs. Herein, we designed and optimized a method that employs a glucose analogue labelled with a fluorophore which takes advantage of the different metabolic pathways of cancer cells to discern them from normal ones...

Chronic inflammation is increasingly recognized as an important component of tumorigenesis and metabolic diseases. The roles of microRNA149* (miRNA149*) in inflammation remain poorly understood. Here, we demonstrate that miR-149* is a suppressor of STAT3-mediated inflammation. MiR-149*-/- mice were generated with CRISPR/CAS9 technique. In a lipopolysaccharide (LPS)-induced inflammation model, miR-149*-/- mice show more severe liver injury and inflammation, compared with wild-type (WT) mice. MiR-149*-/- mice also displayed elevated messenger RNA (mRNA) levels of interleukin (IL)-6, inducible nitric oxide synthase (iNOS), complement C3 (C3) and IL-4 in response to LPS...

Residual risk, which cannot be prevented by statins alone, must be controlled for inhibiting the onset of coronary events. Omega-3 polyunsaturated fatty acids (PUFAs) play an important role in controlling residual risk. The Japan eicosapentaenoic acid (EPA) Lipid Intervention Study demonstrated the inhibitory effect of high-purity EPA preparations on the residual risk of cardiovascular events. Omega-3 PUFAs inhibit coronary artery disease (CAD) through various actions, including triglyceride-lowering action...

New, safe and effective drugs are urgently needed to treat and control malaria and tuberculosis, which affect millions of people annually. However, financial return on investment in the poor settings where these diseases are mostly prevalent is very minimal to support market-driven drug discovery and development. Moreover, the imminent loss of therapeutic lifespan of existing therapies due to evolution and spread of drug resistance further compounds the urgency to identify novel effective drugs. However, the advent of new public-private partnerships focused on tropical diseases and the recent release of large data sets by pharmaceutical companies on antimalarial and antituberculosis compounds derived from phenotypic whole cell high throughput screening have spurred renewed interest and opened new frontiers in malaria and tuberculosis drug discovery...

Acute myocardial infarction (AMI) is a common disease with serious consequences in mortality and cost. Here we aim to screen the differentially expressed genes (DEGs) as biomarkers for early diagnosis of AMI. The microarray data of AMI was downloaded from Gene Expression Omnibus (GEO), including two independent types of research GSE66360 and GSE62646. The DEGs between control and processed samples were screened out by using limma package. Meanwhile, we performed functional analysis of GO terms and/or KEGG pathways to observe the enriched pathways of the DEGs...

Chronic obstructive pulmonary disease (COPD) still remains a serious public health problem, which is a common cause of disability and death in the able-bodied population. Furthermore, the number of patients with metabolic syndrome (MS) is steadily increasing worldwide. Recently, there is also an increase in the number of patients with COPD concurrent with MS, which is a mutually confounding risk factor for concomitant cardiovascular disease and adversely affects prognosis in these patients. Systemic subclinical inflammation is a common link between COPD and the components of MS...

Several echinoderms, including sea urchins, are valuable sources of bioactive compounds but their nutraceutical potential is largely unexplored. In fact, the gonads of some sea urchin species contain antioxidants including carotenoids and polyhydroxylated naphthoquinones (PHNQ's), such as echinochrome A. Astaxanthin is known to have particular bioactivity for the prevention of neurodegenerative diseases. This carotenoid is produced by microalgae, while several marine invertebrates can bioaccumulate or synthetize it from metabolic precursors...
