Call for proposals to create in vitro inhalation tests for nanomaterial toxicity

I got an email announcement (March 17, 2015) which has acted as a spur to my desire to follow up on my Deux Seurats: one (was an artist) and one (is an inquiry into scientifically sound alternatives to animal testing) of December 26, 2014 post.

First, here’s a March 16, 2015 PETA (People for the Ethical Treatment of Animals) International Science Consortium (PISC) press release which describes a practical and scientific initiative for finding alternatives to animal testing,

Today, the PETA International Science Consortium Ltd. put out a request for proposals (RFP) to identify facilities that can develop an in vitro test that, when used in an integrated approach, has the potential to replace the current test conducted on animals to assess the inhalation toxicity of nanomaterials.

The RFP follows a workshop, organized by the Science Consortium and held at U.S. Environmental Protection Agency headquarters in Washington, D.C., that brought together scientific experts from government, industry, academia, and nonprofit organizations from around the world. The goal of the workshop was to make specific recommendations on the design of this in vitro test, including cell types, endpoints, exposure systems, and dosimetry considerations required to develop the in vitro model.

Based on the recommendations from the workshop, the RFP seeks facilities to develop a method that can assess the induction of pulmonary fibrosis in cells co-cultured at the air-liquid interface following exposure to aerosolized multi-walled carbon nanotubes. The Science Consortium will fund this work.

“For both scientific and ethical reasons, there is interest in developing a non-animal method that is faster, cheaper, and more relevant to the human situation,” says the Science Consortium’s Dr. Amy Clippinger.

The long-term vision is to include this in vitro test in a battery of in silico and in vitro assays that can be used in an integrated testing strategy, providing comprehensive information on biological endpoints relevant to inhalation exposure to nanomaterials to be used in the hazard ranking of substances in the risk-assessment process.

The request for proposals can be found here. The proposal deadline is May 29, 2015.

I see the research focus is on multi-walled carbon nanotubes. This makes sense since research has shown that long fibres act like the asbestos fibres they resemble when found in the lung.

Second, I’m hoping to follow up my Deux Seurats piece soon with the tentatively titled, The trouble with mice and … .

Deadline extension (travel grants and poster abstracts) for alternate testing strategies (ATS) of nanomaterials workshop

It seems there have been a couple of deadline extensions (to August 1, 2014) for the September 15-16, 2014 ‘Workshop to Explore How a Multiple Models Approach can Advance Risk Analysis of Nanoscale Materials’ in Washington, DC (first mentioned in my July 10, 2014 posting featuring a description of the workshop). You can go here to submit a poster abstract (from any country) and you can go here if you’re a student or young professional (from any country) in search of a $500 travel award.

I managed to speak to one of the organizers, Lorraine Sheremeta, (Assistant Director, Ingenuity Lab, University of Alberta and co-author a July 9, 2014 Nanowerk Spotlight article about the workshop). Lorraine (Lori) kindly spoke to me about the upcoming workshop, which she described as an academic conference,.

As I understand what she told me, the hosts for the September 15-16, 2014 Workshop to Explore How a Multiple Models Approach can Advance Risk Analysis of Nanoscale Materials in Washington, DC want to attract a multidisciplinary group of people to grapple with a few questions. First, they want to establish a framework for establishing which are the best test methods for nanomaterials. Second, they are trying to move away from animal testing and want to establish which methods are equal to or better than animal testing. Thirdly, they want to discuss what they are going to do with the toxicological data  that we have  been collecting on nanomaterials for years now.

Or, as she and her colleague from the Society of Risk Analysis (Jo Anne Shatkin) have put in it in their Nanowerk Spotlight article:

… develop a report on the State of the Science for ATS for nanomaterials, catalogue of existing and emerging ATS [alternate testing strategies] methods in a database; and develop a case study to inform workshop deliberations and expert recommendations

The collaborative team behind this event includes, the University of Alberta’s Ingenuity Lab, the Society for Risk Analysis, Environment Canada, Health Canada, and the Organization for Economic Co-operation and Development (OECD) Working Party on Manufactured Nanomaterials (WPMN) .

The speaker lineup isn’t settled at this time although they have confirmed Vicki Stone of Heriot-Watt University in Scotland (from her university bio page),

Vicki Stone, Professor of Toxicology, studies the effects of nanomaterials on humans and environmentally relevant species.  Current research projects investigate the mechanism of toxicity of a range of nanomaterials in cells of the immune system (macrophages and neutrophils), liver (hepatocytes) , gastrointestinal tract, blood vessels (endothelium) and lung.  She is interested in interactions between nanomaterials, proteins and lipids, and how this influences subsequent toxicity.  Current projects also develop in vitro alternatives using microfluidics as well as high resolution imaging of individual nanomaterials in 3D and over time.  In addition Vicki collaborates with ecotoxicologists to investigate the impacts of nanomaterials on aquatic organisms. Vicki coordinated a European project to identify the research priorities to develop an intelligent testing strategy for nanomaterials (www.its-nano.eu).

Vicki is Director of the Nano Safety Research Group at Heriot-Watt University, Edinburgh, and Director of Toxicology for SAFENANO (www.safenano.org). She has acted as the Editor-in-chief of the journal Nanotoxicology (http://informahealthcare.com/nan) for 6 years (2006-2011). Vicki has also published over 130 publications pertaining to particle toxicology over the last 16 years and has provided evidence for the government commissioned reports published by the Royal Society (2003) and the on Environmental Pollution (2008).  Vicki was previously a member of the UK Government Committee on the Medical Effects of Air Pollution (COMEAP) and an advisory board member for the Center for the Environmental Implications of NanoTechnology (CEINT; funded by the US Environmental Protection Agency)).

A representative from PETA (People for the Ethical Treatment of Animals) will also be speaking. I believe that will be Amy Clippinger (from the PETA website’s Regulatory Testing webpage; scroll down about 70% of the way),

Science adviser Amy Clippinger has a Ph.D. in cellular and molecular biology and genetics and several years of research experience at the University of Pennsylvania.

PETA representatives have been to at least one other conference on the topic of nano, toxicology, and animal testing as per my April 24, 2014 posting about NANOTOX 2014 in Turkey,

Writing about nanotechnology can lead you in many different directions such as the news about PETA (People for the Ethical Treatment of Animals) and its poster presentation at the NanoTox 2014 conference being held in Antalya, Turkey from April 23 – 26, 2014. From the April 22, 2014 PETA news release on EurekAlert,

PETA International Science Consortium Ltd.’s nanotechnology expert will present a poster titled “A tiered-testing strategy for nanomaterial hazard assessment” at the 7th International Nanotoxicology Congress [NanoTox 2014] to be held April 23-26, 2014, in Antalya, Turkey.

Dr. Monita Sharma will outline a strategy consistent with the 2007 report from the US National Academy of Sciences, “Toxicity Testing in the 21st Century: A Vision and a Strategy,” which recommends use of non-animal methods involving human cells and cell lines for mechanistic pathway–based toxicity studies.

There is a lot of interest internationally in improving how we test for toxicity of nanomaterials. As well, the drive to eliminate or minimize as much as possible the use of animals in testing seems to be gaining momentum.

Good luck to everyone submitting a poster abstract and/or an application for a travel grant!
