Research Overview

Research in the lab is focused on determining the mechanisms underlying thalidomide-induced teratogenesis; identifying non-teratogenic forms of thalidomide; studying the actions of Primodos (was used as a hormone pregnancy test and alleged to have caused birth defects); screening drugs to identify their function/s and action/s; studying how blood vessels are involved in controlling normal and abnormal limb development; studying the role of the YAP signaling pathway in embryonic development; using the chicken embryo to produce a model of Clubfoot to understand how this common birth anomaly comes about; and understanding how birth defects come about in general.

My recent research on Primodos, helped contribute to the establishment of an Independent Medicines and Medical Devices Safety Review in 2018, which i contributed to and which concluded Primodos survivors deserve an apology and compensation in July 2020.

Current Research

PRIMODOS:

Primodos was used as a hormone pregnancy test between 1958-1978. It is alleged to have caused birth defects in children exposed to the drug when their mother was trying to confirm they were pregnant. Conflicting research results was obtained from studies in the 1970s and 1980s. We have investigated the actions of the components of the drug in Zebrafish embryos and show Primodos can harm zebrafish embryos.

For an overview of the history of Primodos, how it worked, the allegations about its safety and why its still relevant to day, have a listen to these Podcast interviews i gave for:

For a discussion on Primodos and its prior use and history please see the following article: https://theconversation.com/is-primodos-the-forgotten-thalidomide-50673

Our Primodos paper using zebrafish embryos was published in 'Scientific Reports' on 13 Feb 2018 and which received widespread media coverage (Sky News, BBC, ITV, newspapers and online media)

We have demonstrated (Therapontos et al., 2009) how thalidomide can cause limb malformations. The drug was used as a non-addictive, non-barbiturate sedative and was also prescribed to pregnant women suffering from morning-sickness (typically, but not exclusively, between weeks 5-10). Tragically over 10000 children were born with severe birth defects, notably, and commonly, limb malformations.

Using analogs and metabolic byproducts of the drug, we showed that the antiangiogenic action of the drug causes limb defects, through preventing blood vessel migration into the developing limb bud. We further showed how the drug exerts its antiangiogenic effect, through preventing endothelial cell proliferation and migration and thus, preventing vessel tube networks from forming. At the time the limb forms (which in humans is around 5-8 weeks) it has a highly changeable vessel pattern - whereas the rest of the body has a stable vascular network. Thalidomide therefore may prevent new vessel outgrowth, which then causes an increase in cell death and loss of limb signalling pathways, stopping limb formation.

Our worked received national and international interest. Including interviews on BBC TV, ITV and in a large number of newspapers, including The Independent, The Daily Mail, The Scotsman, The Press & Journal, The Sunday Times, The New York Times (twice), Nature News, several national and international Radio stations including BBC Radio 4 'The Material World', BBC Radio 4 'The Today Programme', The Naked Scientists (twice), German Public Radio and the US National Public Radio Show 'The Diane Rehm Show' (http://thedianerehmshow.org/shows/2010-09-16/thalidomide-and-fda)

Making safer Thalidomide alternatives:

We are also interested in identifying thalidomide alternatives that retain the clinical benefits of the drug (successfully used to treat Leprosy and Multiple Myeloma) with lessened or no side-effect (eg: birth defect, peripheral neuropathy). To this end we have compared the effects of Thalidomide with its structural analogs, Lenalidomide and Pomalidomide. We demonstrated that the minor structural changes in Pomalidomide make this compound more anti-inflammatory (and not teratogenic in chicken and zebrafish embryos) at lower concentrations than Thalidomide and Lenalidomide (Mahony et al., 2013). We have also screened fluorinated thalidomide analogs and demonstrated differences in analog activities (Beedie et al., 2015). These findings validate making structural changes to Thalidomide to try to find safer alternatives.

Following on from this work we have screened over 80 thalidomide analogs in our zebrafish and chicken embryo assays and identified several with actions that retain clinical advantages (ie: anti-inflammatory) with reduced or no observable teratogenic effects in zebrafish and chicken embryos (Beedie et al., 2016). Some of these analogs have been patented.

Impact:

My research has led to requests to advise the WHO and several international Governments. Including Canada and Australia who have since apologised to thalidomide survivors and offered survivors compensation packages. Moreover my research work has led to meeting thalidomide victims from all over the world and discussing the mechanism of the drugs action.

Some images of my thalidomide work is featured in a Fine Art Exhibition (and subsequent Book) by the renowned artist, Taryn Simon. The Exhibition is entitled: ‘A Living Man Declared Dead and Other Chapters’ and toured the world throughout 2011 and 2012.

Awards for Public Engagement

Winner, 2017 Principal's Prize for Public Engagement with Research - Senior Award.

https://www.abdn.ac.uk/engage/staff-students/2column-page-152-152.php

Some of the Lab's research on Primodos, a now disused hormone pregnancy test alleged to have also caused birth defects, featured in a Sky News & Sky Atlantic documentary  (https://www.youtube.com/watch?v=7ZRkCNUQvBA) and Neil was part of resulting interviews, including on Sky News Live (21 March, 2017) and news stories in national and international media. Neil also discussed the Primodos research and answered questions from MP’s and Lords at the Houses of Parliament at a special event where the Sky News documentary was premiered. In addition, Neil presented the Primodos research to an Expert Working Group of the UK’s Medicine and Healthcare Regulatory Agency who are determining if Primodos could have caused birth defects – their decision due in late 2017. Neil’s other research interest is understanding how thalidomide caused birth defects and identifying forms of the drug that retain clinical benefit without the spectre of birth defects. This work led to an advisory role to the World Health Organisation in 2014 which has contributed to advisory notices about the diagnosis and causation of thalidomide embryopathy from the World Health Organisation. In addition, Neil gave evidence to the Health Committee of the Canadian House’s of Parliament in 2017 investigating how the drug caused birth defects and the range of damage it induces, as part of the Canadian Government’s scheme of who and how to award compensation for thalidomide damage. Neil has also written several popular articles in 2015 and 2016 for the website ‘theconversation.com’ on Primodos (https://theconversation.com/is-primodos-the-forgotten-thalidomide-50673), thalidomide (https://theconversation.com/thalidomide-the-drug-with-a-dark-side-but-an-enigmatic-future-50330) and the zika virus and how it might cause birth defects (https://theconversation.com/proving-that-the-zika-virus-causes-microcephaly-53716).
