TOXI Program at the ACS Meeting
ACS Fall 2021 Atlanta and online hybrid National Meeting Program; August 22-26
The TOXI division celebrated the 25th anniversary of its founding in 2021 with a hybrid in-person and online meeting program. The meeting was held Sunday-Wednesday with scientific sessions, professional development opportunities and division business meetings. Posters and talks were presented live, and many recorded presentations were also available during and after the meeting. The Program Committee and the TOXI division thank NIEHS, Chemical Research in Toxicology, Thermo Fisher Scientific, Bristol Myers Squibb, ACS, TOXI members, and Frederick and Susan Beland for generous funding of our program. Sunday and Monday featured both in-person and online content, following public health recommendations.
The meeting kicked off on Sunday with two award symposia. Congratulations to Prof. Christie Sayes at Baylor University for the Chemical Research in Toxicology Young Investigator Award for her work on toxicology along the supply chain, with a focus on nanomaterial toxicity. She organized an exciting symposium that included Robert Strongin, Portland State University, who spoke about potential environmental exposures due to vaping products. Sherine Obare, University of North Carolina, Greensboro, spoke about her work on nanoparticle toxicity, while the work of April Gu’s laboratory at Cornell on drinking water disinfection byproducts was also presented.
Prof. John Essigmann from MIT was recognized with the TOXI Division Founders’ Award for his work on DNA damage and mutagenesis. Prof. Essigmann organized a symposium featuring an arc of work on the metabolism of DNA lesions in multiple cellular contexts. Also included in the symposium were Natalia Tretyakova (University of Minnesota), who discussed DNA-protein cross-links; Deyu Li (University of Rhode Island), who presented his work on identifying endogenously generated lesions that can be substrates for damage bypass DNA polymerases; Sarah Delaney (Brown University), who spoke about base excision repair in the context of chromatin; Shana Sturla (ETH-Zurich), who presented her work on genomic patterns of chemically induced DNA damage and mutagenesis.
The TOXI keynote address was given by Patrick Breysse from the Centers for Disease Control, who gave an insightful and wide-ranging presentation featuring several different examples of how biological monitoring can inform public health and regulatory decision-making.
Michael Trakselis, Baylor University, and Laura Niedernhofer, University of Minnesota, organized a session on Toxicants and Cellular Aging co-sponsored with the BIOL division. Michael Trakselis presented his group’s work on the involvement of the MCM8/9 recombination helicase in stabilizing stalled replication forks and regulating fork progression. Non-B-DNA forms H-DNA and Z-DNA contribute to mutagenesis due to their enrichment near translocation regions, as discussed by Karen Vasquez, University of Texas, Austin. Patricia Opresko, University of Pittsburgh, presented a tool developed by her laboratory to induce oxidative stress and generate 8-oxo-dG only in telomeres in order to probe the mechanisms by which chronic 8-oxo-dG leads to telomere fragility and loss, triggering senescence. Weiwei Dang, Baylor College of Medicine, addressed the effects of histone levels and modifications in yeast lifespan. Finally, Laura Niedernhofer reported on her work showing that senescent cells play a causal role in aging and age-related diseases.
An in-person poster session was held in Atlanta Sunday evening, complemented by an online poster session on Tuesday. Posters were also available throughout the meeting with short recorded presentations.
Monday morning featured the Student and Postdoctoral Scholar Symposium, organized by Erin Prestwich and Ujjal Sarker. Some highlights include Merve Demir’s, University of California, Davis, identification of a MutY loop that is important for 8-oxo-dG recognition, and Taylor Dodson’s, University of Toledo, work showing the changed in tRNA modifications due to diabetes.
The 25th anniversary of the TOXI division was celebrated with a symposium organized by Michael Trakselis and Sarah Shuck, City of Hope, featuring former and current TOXI division leaders Fred Guengerich, Vanderbilt University, Nicholas Geacintov, New York University, Lisa Peterson, University of Minnesota, Stephen Hecht, University of Minnesota, Shana Sturla, and Natalia Tretyakova. Michael Stone, Vanderbilt University, gave a historical overview of the early days of the division. The symposium highlighted the development of the division in parallel with the development of the different scientific fields of interest to the division.
Thinking Outside the Well: Novel Assays in Drug Discovery & Development was organized by Donna Huryn, University of Pittsburgh, and Michael Walters, University of Minnesota and co-sponsored with the MEDI division. Donna Huryn described a zebrafish model system for screening compounds active in treating acute kidney injury, a disease common in those spending time in the ICU and for which there are no prognostic biomarkers. Randall Peterson, University of Utah, described another zebrafish screen, in this case identifying chemicals that disrupt social behavior in fish to identify autism-related genes. Thalita Boldrin Zanoni, Charles River Laboratories; Banupriya Sridharan, GlaxoSmithKline, and Marc Ferrer, National Institutes of Health, discussed cell and tissue models that can reduce the need for animal models in research and development.
TOXI hosted a live poster session Tuesday morning on Gather (gather.town), which allowed participants to browse posters and interact with participants mimicking an in-person poster session.
The Topics in Chemical Toxicology symposium was organized by Sarah Shuck and Linlin Zhao. Shilpi Paul, Pennsylvania State University Hershey described work to determine proteins associated with damage-bypass polymerase pol kappa in human cells. Kari Knobbe, University of Missouri, reported the development of a model describing steroid metabolism by cytochrome P450 in stress responses. The excellent presentations in this session covered a range of topics including, a range of methods to detect and characterize toxicants and their metabolites in cells, repair of DNA adducts, and their cytotoxicity.
Harnessing the Microbiome for Disease Prevention & Therapy, organized by Nick Meanwell, Bristol Myers Squibb, and Fred Guengerich, featured James Brown, Kaleido Biosciences; Jingwei Cai, Genentech; Jason Crawford, Yale University; and Beth McCormick, University of Massachusetts Medical School. Presentations covered a range of topics related to host-microbe interactions and the impact of the metabolism of each on drug discovery.
The TOXI programming wrapped up on Wednesday with a Publishing workshop, led by Chemical Research in Toxicology editors and the TOXI business meeting. An excellent conclusion to the meeting was the Career Mentoring Panel Discussion organized by Sarah Shuck and featuring Amanda Bryant-Friedrich (Wayne State University), Kirsten Fertuck (Northeastern University), and Jason Walsh (Pfizer). Participants benefitted from the insightful discussion on identifying mentors, the value of multiple mentors, seeking and using career advice, and many more topics.
