Acetaminophen cytotoxicity in HepG2 cells is associated with a decoupling of glycolysis from the TCA cycle, loss of NADPH production, and suppression of anabolism.

Arch Toxicol 2018 Dec 14. Epub 2018 Dec 14.

Department of Surgery and Cancer, Faculty of Medicine, Imperial College London, London, UK.

Acetaminophen (APAP) is one of the most commonly used analgesics worldwide, and overdoses are associated with lactic acidosis, hepatocyte toxicity, and acute liver failure due to oxidative stress and mitochondrial dysfunction. Hepatoma cell lines typically lack the CYP450 activity to generate the reactive metabolite of APAP observed in vivo, but are still subject to APAP cytotoxicity. In this study, we employed metabolic profiling and isotope labelling approaches to investigate the metabolic impact of acute exposure to cytotoxic doses of APAP on the widely used HepG2 cell model.

Aging of Antiviral CD8 Memory T Cells Fosters Increased Survival, Metabolic Adaptations, and Lymphoid Tissue Homing.

J Immunol 2018 Dec 14. Epub 2018 Dec 14.

Department of Anesthesiology, University of Colorado Denver, Aurora, CO 80045;

Aging of established antiviral T cell memory can foster a series of progressive adaptations that paradoxically improve rather than compromise protective CD8 T cell immunity. We now provide evidence that this gradual evolution, the pace of which is contingent on the precise context of the primary response, also impinges on the molecular mechanisms that regulate CD8 memory T cell (T) homeostasis. Over time, CD8 T generated in the wake of an acute infection with the natural murine pathogen lymphocytic choriomeningitis virus become more resistant to apoptosis and acquire enhanced cytokine responsiveness without adjusting their homeostatic proliferation rates; concurrent metabolic adaptations promote increased CD8 T quiescence and fitness but also impart the reacquisition of a partial effector-like metabolic profile; and a gradual redistribution of aging CD8 T from blood and nonlymphoid tissues to lymphatic organs results in CD8 T accumulations in bone marrow, splenic white pulp, and, particularly, lymph nodes.

Generating accurate in vitro intrinsic clearance data is an important aspect of predicting in vivo human clearance. Primary hepatocytes in suspension are routinely used to predict in vivo clearance; however, incubation times have typically been limited to 4-6 hours, which is not long enough to accurately evaluate the metabolic stability of slowly metabolized compounds. HepatoPac is a micropatterened hepatocyte-fibroblast coculture system that can be used for continuous incubations of up to 7 days. Read More

Development of an anti-hepatitis B virus (HBV) agent through the structure-activity relationship of the interferon-like small compound CDM-3008.

Bioorg Med Chem 2018 Dec 5. Epub 2018 Dec 5.

Department of System Chemotherapy and Molecular Sciences, Division of Bioinformatics and Chemical Genomics, Graduate School of Pharmaceutical Sciences, Kyoto University, Sakyo-ku, Kyoto 606-8501, Japan. Electronic address:

Hepatitis B, a viral infectious disease caused by hepatitis B virus (HBV), is a life-threatening disease that leads liver cirrhosis and liver cancer. Because the current treatments for HBV, such as an interferon (IFN) formulation or nucleoside/nucleotide analogues, are not sufficient, the development of a more effective agent for HBV is urgent required. CDM-3008 (1, 2-(2,4-bis(trifluoromethyl)imidazo[1,2-a][1,8]naphthyridin-8-yl)-1,3,4-oxadiazole) (RO8191)) is a small molecule with an imidazo[1,2-a][1,8]naphthyridine scaffold that shows anti-HCV activity with an IFN-like effect.

Parathyroid carcinoma.

Best Pract Res Clin Endocrinol Metab 2018 Dec 1. Epub 2018 Dec 1.

Departments of Laboratory Medicine and Pathobiology, Medicine and Genetics, University of Toronto, Toronto, Ontario, Canada. Electronic address:

Parathyroid carcinoma (PC) is a rare disease with an indolent behavior due to the low malignant potential. The etiology is unknown. Somatic mutations of CDC73 gene, the same gene involved in the hyperparathyroidism-jaw tumor syndrome, can be identified in up to 70% of patients with PC and in one-third of cases the mutations are germline.

Identification of 2-(2'-fluoro-[1,1'-biphenyl]-2-yl)acetamide as a Sodium Valproate-like broad spectrum anti-epileptic drug candidate.

Bioorg Med Chem Lett 2018 Dec 7. Epub 2018 Dec 7.

Drug Research Division, Sumitomo Dainippon Pharma Co., Ltd, 3-1-98 Kasugade-naka Konohana-ku, Osaka 554-0022, Japan.

By further optimizing compound A [2'-fluoro-N-methyl-[1,1'-biphenyl]-2-sulfonamide], we identified DSP-0565 [2-(2'-fluoro-[1,1'-biphenyl]-2-yl)acetamide, 17a] as a strong, broad-spectrum anti-epileptic drug (AED) candidate. Our efforts mainly focused on finding an alternative polar group for the sulfonamide in order to improve ADME profile of compound A including good metabolic stability and no reactive metabolic production. This led to the identification of biphenyl acetamide as a new scaffold for development of broad-spectrum AED candidates. Read More

Immune-metabolic interactions during systemic and enteric infection in Drosophila.

Curr Opin Insect Sci 2018 Oct 28;29:21-26. Epub 2018 May 28.

Electronic address:

Immune-metabolic interactions are evolutionarily conserved phenomena observed in all metazoans, from invertebrates to vertebrates. Although it is believed that immune activation drives chronic metabolic diseases, clear conclusions about the reasons and mechanisms of cross-talk between immune and metabolic signaling cannot be drawn. The Drosophila insect model equipped with genetically well-defined immune and metabolic signaling pathways is suitable in understanding the molecular codes underlying immune-metabolic interactions.

The functional decoupling of processes in alpine ecosystems under climate change.

Curr Opin Insect Sci 2018 Oct 17;29:126-132. Epub 2018 Jul 17.

Laboratory of Functional Ecology, Institute of Biology, University of Neuchâtel, Rue Emile-Argand 11, 2000 Neuchâtel, Switzerland. Electronic address:

Climate change may promote the decoupling of the different above-ground and below-ground compartments of high elevation ecosystems. Along elevation gradients, a trade-off between species tolerance to cold climates and metabolic rates dictates that cold adapted organisms display a lower efficiency in decomposition, growth or herbivory. As a consequence, if dispersal or evolution under climate change is systematically faster for agents of one compartment (e. Read More

Curr Opin Insect Sci 2018 Oct 26;29:1-6. Epub 2018 May 26.

Department of Entomology and Department of Molecular Biology & Genetics, Cornell University, Ithaca, NY 14853, USA. Electronic address:

Omic studies of metabolic interactions between insects and their microbial symbionts enable us to construct precise hypotheses, especially regarding the metabolic services provided by microbial partners and the identity of metabolites exchanged between microorganisms and the insect host. Valuable sources of information include the complement of metabolism-related genes in the microbial partners, and differences in the abundance of transcripts, proteins or metabolites, either between microbe-bearing organs and the whole body or between insects bearing and lacking microbial symbionts. Hypotheses generated from omic data can, most productively, be tested by experiments using reverse genetics for precise manipulation of the gene expression. Read More

PIF-mediated sucrose regulation of the circadian oscillator is light quality and temperature dependent.

Genes (Basel) 2018 Dec 13;9(12). Epub 2018 Dec 13.

Department of Plant and Environmental Sciences, Institute for Life Sciences, Edmond J. Safra Campus, Givat Ram, Hebrew University, Jerusalem 91904, Israel.

Studies are increasingly showing that metabolic and circadian (~24 h) pathways are strongly interconnected, with the circadian system regulating the metabolic state of the cell, and metabolic products feeding back to entrain the oscillator. In plants, probably the most significant impact of the circadian system on metabolism is in its reciprocal regulation of photosynthesis; however, the pathways by which this occurs are still poorly understood. We have previously shown that members of the basic helix-loop-helix (bHLH) transcription factor PHYTOCHROME INTERACTING FACTOR (PIF) family are involved in the photosynthate entrainment of the circadian oscillator.

Pediatric Fatty Liver and Obesity: Not Always Justa Matter of Non-Alcoholic Fatty Liver Disease.

Children (Basel) 2018 Dec 13;5(12). Epub 2018 Dec 13.

Pediatrics Residency Joint Programs, University of Naples Federico II, 80131 Naples, Italy.

Obesity-related non-alcoholic fatty liver disease (NAFLD) represents the most common cause of pediatric liver disease due to overweight/obesity large-scale epidemics. In clinical practice, diagnosis is usually based on clinical features, blood tests, and liver imaging. Here, we underline the need to make a correct differential diagnosis for a number of genetic, metabolic, gastrointestinal, nutritional, endocrine, muscular, and systemic disorders, and for iatrogenic/viral/autoimmune hepatitis as well.
