Tissue-Based SARS-Cov-2 Detection in Fatal COVID-19 Infections: Sustained Direct Viral-Induced Damage is Not Necessary to Drive Disease Progression.

Hum Pathol 2021 May 4. Epub 2021 May 4.

Departments of Pathology, Molecular and Cell-Based Medicine, The Icahn School of Medicine at Mount Sinai Hospital, New York, NY. Electronic address:

Background: Coronavirus disease 2019 (COVID-19) is an ongoing pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Although viral infection is known to trigger inflammatory processes contributing to tissue injury and organ failure, it is unclear whether direct viral damage is needed to sustain cellular injury. An understanding of pathogenic mechanisms has been handicapped by the absence of optimized methods to visualize the presence and distribution of SARS-CoV-2 in damaged tissues. Read More

Iron oxide nanoparticles aggravate hepatic steatosis and liver injury in nonalcoholic fatty liver disease through BMP-SMAD-mediated hepatic iron overload.

Nanotoxicology 2021 May 7:1-18. Epub 2021 May 7.

CAS Key Laboratory for Biomedical Effects of Nanomaterials and Nanosafety, Institute of High Energy Physics, Chinese Academy of Sciences (CAS), Beijing, China.

Nonalcoholic fatty liver disease (NAFLD) is the leading hepatic manifestation of metabolic syndrome worldwide, and is clinically accompanied by iron overload. As the increasing application of iron oxide nanoparticles (IONPs) on the imaging and diagnosis in NAFLD, the potential hepatic effect and mechanism of IONPs on NAFLD should be well studied. Here, we demonstrate that carboxyl-modified (COOH-IONPs) and amino-coated IONPs (NH-IONPs) exhibit no significant hepatic toxicity in normal mice at the clinical injection dose, but aggravate SREBP-1c-mediated lipogenesis (DNL) in the livers of mice with NAFLD induced by high-fat diet (HFD) and in HepG2 cells incubated with oleic acid (OA), especially in those treated by the positive NH-IONPs.

Liver Int 2021 May 7. Epub 2021 May 7.

Institute of Tropical Medicine, University of Tübingen, Wilhelmstrasse 27, 72074, Tübingen, Germany.

The hepatitis E virus (HEV) is one of the main causes of acute hepatitis and the de facto global burden is underestimated. HEV-related clinical complications are often undetected and are not considered in the differential diagnosis. Convincing findings from studies suggest that HEV is clinically relevant not only in developing countries but also in industrialized countries. Read More

Drug-induced liver injury: Oltipraz and C2-ceramide intervene HNF-1α/GSTA1 expression via JNK signaling pathway.

J Appl Toxicol 2021 May 6. Epub 2021 May 6.

Department of Basic Veterinary Science, College of Veterinary Medicine, Northeast Agricultural University, Harbin, China.

Drug-induced liver injury (DILI) is a serious and frequently occurring issue in drug development. The c-Jun N-terminal kinase (JNK) signaling pathway plays an important role in many diseases; hepatocyte nuclear factor-1α (HNF-1α) and glutathione S-transferase A1 (GSTA1) are important in regulating liver-specific genes expressions and affecting drug metabolism. Oltipraz is used to treat liver cirrhosis by improving liver function, and C2-ceramide is a pro-apoptotic lipid that regulates multiple signaling pathways. Read More

Integration of temporal single cell cellular stress response activity with Logic-ODE modeling reveals activation of ATF4-CHOP axis as a critical predictor of drug-induced liver injury.

Biochem Pharmacol 2021 May 3:114591. Epub 2021 May 3.

Division of Drug Discovery and Safety, Leiden Academic Centre for Drug Research, Leiden University, Leiden, The Netherlands. Electronic address:

Drug-induced liver injury (DILI) is the most prevalent adversity encountered in drug development and clinical settings leading to urgent needs to understand the underlying mechanisms. In this study, we have systematically investigated the dynamics of the activation of cellular stress response pathways and cell death outcomes upon exposure of a panel of liver toxicants using live cell imaging of fluorescent reporter cell lines. We established a comprehensive temporal dynamic response profile of a large set of BAC-GFP HepG2 cell lines representing the following components of stress signaling: i) unfolded protein response (UPR) [ATF4, XBP1, BIP and CHOP]; ii) oxidative stress [NRF2, SRXN1, HMOX1]; iii) DNA damage [P53, P21, BTG2, MDM2]; and iv) NF-κB pathway [A20, ICAM1].
