Potential mechanism for liver injury due to chronic alcohol consumption and hyperglycemia

Scientists from India have examined the roles of alcohol and high glucose levels on ethanol metabolizing enzymes and how such conditions can promote oxidative stress and cellular damage. Diabetes, characterized by the presence of inherent oxidative stress, may be further complicated by the additional oxidative stress generated due to the metabolism of alcohol.

Interviewing Frederik-Jan van Schooten, Associate Editor for Toxicology Research

Toxicology research Associate Editor Frederik-Jan van SchootenFrederik-Jan van Schooten is a Professor of Genetic Toxicology at Maastricht University Medical Centre and is the Head of Department for the Department of Health Risk Analysis and Toxicology. As part of the Toxicology Research Editorial Board and one of the journal’s Associate Editors we took this opportunity to ask him a few questions:

1.         What led you to specialise in toxicology?

For the past 30 years I have been working in the field of chemical carcinogenesis and genetic toxicology. From the beginning of my scientific career it has fascinated me how chemical carcinogens induce cancer through damaging DNA and disrupting cellular control, especially how people differ in their response. The question why certain people have an increased susceptibility to chemical exposure and have an enhanced risk of getting cancer is intriguing to me. In toxicology it all comes together; chemical structures, biochemistry, biology, individual susceptibility for disease, and of course how to implement all this knowledge into assessing risks and onto policy making.

2.         What do you think are the most important developments in the field of toxicology at the moment?

Toxicology has grown into a real multidisciplinary discipline. It is not anymore describing phenomena by, for instance, treating animals with a chemical carcinogen and then counting the number of tumours that ultimately arise. Nowadays it is strongly orientated towards molecular mechanisms behind chemical exposures leading to disease by making use of state of the art technologies such as genomics, proteomics and metabolomics. Next to that is the emerging arena of the exposome that is the analytical challenge to judge a person’s lifetime exposure. An important development is the importance of knowing at what time during life we are exposed and especially the prenatal exposure window is increasingly becoming of interest via epigenetic imprinting. The following quote is still inspiring me: “What is it that is not a poison? All things are poisons and nothing is without poison. It is the dose only that makes a thing not a poison.” Who said this a long time ago? Right; Paracelsus, 1493-1541.

3.         How do you envisage toxicology research developing in the future?

Toxicology is developing into a real important and modern field of science that is highly relevant for society. It integrates all modern insights in science and the gained knowledge is increasingly important for an array of societal applications including refinement of risk assessment, replacement of animals in chemical testing and also applications in translational medicine by judging side effects of therapeutics.

4.         You’re one of the Associate Editors for Toxicology Research. What excites you most about your new role?

To say it bluntly, it is my desire to help to make Toxicology Research one of the leading journals dealing with chemical exposures and its effects in ecosystems to humans. I think that science should not be restricted to certain disciplines and that we can learn when crossing borders. And that we should use our imagination and creativity as much as possible to find solutions for the global environmental and societal problems we are facing. I am very proud to be part of a team that has the ambition to go beyond our self-imposed boundaries. Therefore I encourage the scientists to let loose their creativity and submit these papers to this inter-disciplinary journal.

5.         What advice would you give to the students who will be the next generation of scientists?

Research is very exciting. When I was a PhD student I remember how I biked to work in the morning, wondering what my experiment in the lab that night had done. I know that students first have to study hard to gain knowledge before becoming a scientist and sometimes this can be boring. But I advise them to push through because science is so exciting. Once a scientist, many times during the course of their experiments they may face troubles but it is very rewarding when the expectations come true. So, don’t give up because we need young and gifted people.

6.         If you weren’t a scientist, what would you be?

If possible something in a creative direction; perhaps an artist or actor. However I cannot imagine not being in science.

If you would like to submit an article to Toxicology Research, to be handled by Frederik-Jan, you can do so here on our submissions platform.

Review: Mechanisms of lead and manganese neurotoxicity

It has been shown that exposure to high levels of lead and manganese in both children and adults can cause cognitive and behavioural deficits. While both metals having distinct neurological effects, each with different brain targets and modes of action, they do share a key similarity in that they both disrupt synaptic transmission.

In this review Tomas R. Guilarte and April P. Neal summarise the toxicokinetics of lead and manganese; describing their neurotoxic mechanisms and discussing the commonalities in their neurotoxicity.

Safer blood clotting agents for open wounds

New toxicity results show that foams would be safer than the currently used clays as materials to stem blood flow in open wounds.

Blood loss is one of the leading causes of death in both military and civilian casualties. Currently, aluminosilicate layered clays, such as kaolin clay, are used as haemostatic agents (agents that encourage the blood to clot) in dressings to prevent fatalities. These clays have varying degrees of cytotoxicity and can be difficult to remove from wounds, which can lead to thrombosis. Recently, one clay product has been removed from use for this reason.

Haemostatic agents are added to wound dressings to encourage the blood to clot

Now, scientists in Singapore and the US, led by Daniele Zink from the Institute of Bioengineering and Nanotechnology in Singapore and Galen Stucky from the University of California, Santa Barbara, have found, using in vitro tests, that a silica mesocellular foam (MCF-26) is 1–2 orders of magnitude less toxic to human cells than the clays, whereas its potency in promoting blood clotting is similar.

‘MCF-26 would be effective and safer than currently used haemostatic agents,’ says Zink. She adds that the clay particles in their tests to compare the two materials adhered to cell surfaces and were taken up into the cells’ cytoplasm. The MCF-26 was not taken up and was easy to remove.

In vitro models for liver toxicity testing

In this review Ivan Rusyn, University of North Carolina, and co-workers present an overview of various traditional and novel liver-derived in vitro systems for hepatotoxicity testing. Examples of such systems include:

  • Primary hepatocytes cultures,
  • Immortalized cell lines,
  • Co-cultures of hepatocytes with liver non-parenchymal cells,
  • Bioartificial livers.

Rusyn et al. discuss the benefits and disadvantages associated with using traditional in vitro systems whilst also examining the usefulness of the novel in vitro liver models for toxicity testing.
