International Journal of Toxicology

The Research Publications track research that is published across national and international peer-reviewed journals. The most recent articles are available ahead of print and searchable by Journal Title, Subject, USDA Grant Funding Agencies or FDA Grant Funding Agencies. The research publications are tracked across five subject areas: Bacterial Pathogens, Chemical Contaminants, Natural Toxins, Parasites, and Viruses.

The renal proximal tubule cell line, human kidney 2 (HK-2), recapitulates many of the functional cellular and molecular characteristics of differentiated primary proximal tubule cells. These features include anchorage dependence, gluconeogenesis capability, and sodium-dependent sugar transport. In order to ascertain how well HK-2 cells can reliably reveal the toxicological profile of compounds...

Aim:Aflatoxin B1 (AFB1) is hepatotoxic. Numerous studies have shown that mitochondria play an essential role in AFB1-induced steatosis. However, the mechanisms of AFB1-induced steatosis via mitochondria are still obscure. The present study aimed to confirm that AFB1 causes hepatocyte steatosis regulated by cyclooxygenase-2 (COX-2)-induced mitophagy, both in vivo and in vitro.Methods:Adult male...

Polycyclic aromatic hydrocarbons (PAHs) refer to a ubiquitous group of anthropogenic air pollutants that are generated through incomplete carbon combustion. Although the immunotoxic nature of PAHs has been previously reported, the underlying molecular mechanisms of this effect are not fully understood. In the present study, we investigated the mitochondrial-mediated epigenetic regulation of 2...

Zanubrutinib an oral irreversible Bruton’s tyrosine kinase (BTK) inhibitor, is under development for the treatment of a variety of B-cell malignancies and has received accelerated approval by the US Food and Drug Administration for treatment of adult patients with mantel cell lymphoma who have received at least one prior therapy. Zanubrutinib moderately inhibited the human ether- à -go-go-related...

Introduction:The Safety Pharmacology Society (SPS) conducted a membership survey to examine industry practices related mainly to cardiovascular (CV) safety pharmacology (SP).Methods:Questions addressed nonclinical study design, data analysis methods, drug-induced effects, and conventional and novel CV assays.Results:The most frequent therapeutic area targeted by drugs developed by the companies/...

Acrylamide (AA) is a food contaminant present in a wide range of frequently consumed foods, which makes human exposure to this toxicant unfortunately unavoidable. However, efforts to reduce the formation of AA in food have resulted in some success. This review aims to summarize the occurrence of AA and the potential mitigation strategies of its formation in foods. Formation of AA in foods is...

Azo dyes are used widely as color additives in food, drugs, and cosmetics; hence, there is an increasing concern about their safety and possible health hazards. In the present study, we chose 4 azo dyes tartrazine, Sunset Yellow, amaranth, and Allura red and evaluated their developmental toxicity on zebrafish embryos. At concentration levels of 5 to 50 mM, we found that azo dyes can induce...

Cadmium is an environmental pollutant well known for its nephrotoxic effects. Nevertheless, mechanisms underlying nephrotoxicity continue to be elucidated. MicroRNAs (miRNAs) have emerged in recent years as modulators of xenobiotic-induced toxicity. In this context, our study aimed at elucidating whether miRNAs are involved in renal proximal tubular toxicity induced by cadmium exposure. We showed...

Aflatoxin (AF) B1 is a potent hepatotoxic, mutagenic, teratogenic mycotoxin and may cause immune suppression/dysregulation in humans and animals. Toxic effects of AFB1 on key mammalian immune cells (ie, leukocytes) needs to be mechanistically elucidated. In this study, along with the determination of AFB1’s LC50 for certain leukocytes, we analyzed the effect of naturally occurring levels of AFB1...

Background:Acute pancreatitis (AP) is associated with risks of morbidity and mortality. The incidence of AP recently increased compared to that traditionally reported in the literature.Objective:The purpose of this study was to evaluate the possible association between AP and drugs using the Japanese Adverse Drug Event Report (JADER) database, which is a spontaneous reporting database of adverse...

Central nervous system (CNS)-targeted products are an important category of pediatric pharmaceuticals. In view of the significant postnatal maturation of the CNS, juvenile animal studies (JAS) are performed to support pediatric development of these new medicines. In this project, the design and results of juvenile toxicity studies from 15 drug compounds for the treatment of neurologic or...
