Newswise — For more than five decades, the SOT Awards have celebrated visionary toxicologists, exceptional early career scientists, and outstanding postdocs and students. This longstanding tradition continues this year, with SOT acknowledging individuals who have made remarkable contributions to the field of toxicology.

Among the accomplishments of this year’s awardees are discoveries related to the role of altered pharmacokinetics in non-alcoholic fatty liver disease, chemical risk assessments, the mechanisms of Parkinson’s disease neurodegeneration, the mechanisms of dioxin, risk of COVID-19 to smokers and vapers, the mode of action by which certain chemicals induce kidney tumors in male rats, and the role of the microbiome in pregnancy and early developmental programming.

Among the scientific advancements of this year’s award recipients are:

  • Understanding the effects of xenobiotic exposure to nanoparticles and microplastics on pregnancy and fetal health
  • The generation and use of genomics-based data to help inform risk assessment and regulatory decisions
  • The recognition of Gulf War Illness as a neuroinflammatory disorder driven by persistent neuroimmune dysfunction
  • The generation of very large novel datasets in the public domain that can be used for mapping molecular and cellular events in nuclear receptor signaling, stress response, and developmental toxicity pathways.
  • The discovery of the pivotal role of cell proliferation and spontaneous errors during cell replication as contributors to cancer, resulting in non-linear dose-response and thresholds.
  • Clarifying the regulatory mechanisms behind the cellular NRF2-KEAP1 defense system against environmental insults
  • Understanding the molecular mechanisms underlying the initiation of cancer due to chemical exposures, such as to aflatoxin B1 and its metabolite AFB-8,9-epoxide, in our diet and environment
  • More efficient diagnosis and treatment of exposure to chemical warfare agents, notably organophosphorus toxicants and sulfur mustard

The recipients of the 2024 Awards have demonstrated excellence not only in their respective fields but also in leadership, mentorship, and educational roles. This is evident through hundreds of published papers, the positive impact on numerous students and postdocs who have benefited from their guidance, and their influence on various regulations, processes, and standards.

The 2024 new Honorary member and SOT Award recipients will be honored during the Society’s 63rd Annual Meeting and ToxExpo in Salt Lake City, Utah, March 10–14, 2024.

About SOT Awards and Honors

The Society of Toxicology (SOT) Awards program recognizes distinguished toxicologists and students each year based on merit. In 1962, the Society inducted its first Honorary members, establishing its honors program. In 1965, the SOT Awards program was created with the establishment of two awards, the SOT Merit Award and the SOT Achievement Award, to support “the furtherance of the science of toxicology.” Today, the Society presents more than 20 awards that recognize achievement, facilitate travel for senior and budding scientists, and further toxicological research. Hashtag: #SOTAwards
