    I am writing this today from a spring-like Ann Arbor in the end of February, where the temperature today is 48°F with bright sun. Last week we had temperatures up into the 70’s. This is our second very unusual winter in a row. I assume this is a combination of El Niño along with global warming. I certainly hope it is primarily the former and not the latter. However, we will see what it is over the next several years. This is my last newsletter to the membership as I have transitioned to the Past Chair of the Division. It is hard for me to believe how quickly the time has flown. Serving as Chair of our Division has been an incredibly rewarding experience. I enjoyed both working with the highly dedicated TOXI officers and also getting to know many members of our Division. The elected officers have made my work as Chair easy and very enjoyable, and I would like to take this opportunity to thank all of the elected officers that I have had the good fortune to work with.

    In this newsletter we welcome Professor Nicholas Geacintov as the new Chair of the Division. I would also like to inform you of the results of the recent TOXI election. Our new Chair-Elect is Shana Sturla, Professor of Toxicology at the ETH Zurich, Swiss Federal Institute of Toxicology. Mike Stone, Professor of Chemistry and Biochemistry at Vanderbilt University, is our Treasurer-Elect. Steve Hecht, Professor at the University of Minnesota, is the newly elected member of the Nominations Committee. Nick Meanwell, Executive Director of the Department of Discovery Chemistry and Molecular Technologies at Bristol-Myers Squibb, is the Member-at-Large of the Executive Committee. Sylvia Balbo, Assistant Professor in the School of Public Health at the University of Minnesota, is the new Counselor, and Grover Miller, Associate Professor of Biochemistry and Molecular Biology at the University of Arkansas, is the Alternate Counselor. My congratulations and thanks to them for their continuing service to our Division. Please welcome these new officers to our Division.

    The 254th ACS National Meeting will take place in Washington, D.C., August 20th-24th with the program theme “Chemistry’s Impact on the Global Economy”. Our Program Chair, Thomas Spratt has been working hard to put together a really exciting program for the TOXI Division. The abstract deadline for the meeting is March 27th, 2017. I am also pleased to announce that Dr. Ian Blair from the University of Pennsylvania will be presenting the Richard N. Loeppky Lecture as the awardee of the Founders Award. He also has a very exciting lineup of speakers for the Founders Award Symposium. The preliminary program for the Fall Meeting in Washington, D.C. is provided later in this newsletter.

    I would like to gratefully acknowledge and thank the benefactors of our Division in 2016:
    • Bristol-Myers Squibb
    • National Institutes of Environmental Health Sciences
    • U.S. Food and Drug Administration
    • ACS Publications Division

    In our last newsletter, we featured the Young Investigators who were awarded funding for travel to the National Meeting. In this newsletter we are recognizing and highlighting the Young Investigators who won the awards for Best Poster and Oral Presentations at our Annual Meeting in Philadelphia. I would recommend that you take the time to read their research summaries in this newsletter. Their impressive contributions to research indicate that our discipline of chemical toxicology will continue to be in strong hands, and that the Division has an exceptionally bright future. I would like to thank the Division members who helped in the organization of the oral sessions, symposia, poster sessions, and awards ceremonies, and those who presented their outstanding science at our National Meeting in Philadelphia.

    I am pleased to report that the State of the Division is strong, and I know that with Nick at the helm we will continue to grow in stature.

    I would like to close by thanking all of the members of all our Toxicology Division for their continuing strong support.

    I am a doctoral candidate in Pharmacology and trainee in Environmental Health Sciences at the University of Pennsylvania, working under the mentorship of Dr. Trevor Penning. I received my B.S. in Biochemistry at Virginia Tech in 2012. Presently, I am investigating how estrogen receptor-mediated shuttling of genotoxic polycyclic aromatic hydrocarbon (PAH) ortho-quinones into the nucleus may promote lung cancer. Elucidating this mechanism is important, especially in explaining why women are more susceptible to non-smoking-related lung cancers than their male counterparts.

    I am thankful for the training grant, Translational Research Training Program in Environmental Health Sciences (funded by the National Institute of Environmental Health Sciences (NIEHS)), and Dr. Penning for affording me the opportunity to attend the 252nd American Chemical Society National Meeting. I not only had the privilege to listen to the latest scientific findings from some of the best minds in the world, but also had an opportunity to present my work and receive invaluable feedback that will help move my project forward. My poster presentation to the Division of Chemical Toxicology was titled “Estrogen receptor – mediated shuttling of genotoxic PAH ortho-quinones into the nucleus in lung cancer,” and I am enormously grateful and delighted for having been awarded second place for this presentation among graduate students.

    Given the great experience I had in learning, networking and sharing my own scientific findings, I look forward to attending the next ACS National meeting; I especially can’t wait to see what the TOXI Division has in store for us.

    (3rd Place Poster Presentation Awardee)
    I am currently a doctoral candidate in the laboratory of Dr. Jun Xi in the Department of Chemistry at Drexel University in Philadelphia, PA.

    In the Xi laboratory, we are focused on applying innovative sensing based technologies to investigate the properties of biological systems that are relevant to fundamental biology and future medical applications. The quartz crystal microbalance with dissipation monitoring (QCM-D) is an ultrasensitive mechanical sensing device that is capable of providing real-time, non-invasive measurements of the changes in frequency and energy dissipation of adhered cells. Such measurement has allowed us to quantitatively track the real time change in cell adhesion, which can be used as a platform to screen environmental toxins, evaluate potential drug candidates, and examine cell signaling network. My current research efforts involve understanding of the role of the GPCR signaling network in mediating cell adhesion that plays an essential role in tissue repair and regeneration, cellular regulation, and disease progression.

    I am very grateful for the Division of Chemical Toxicology for giving me the opportunity to present my poster titled “Dissipation Monitoring of the QCM-D to Study Ligand-Induced Cell Signaling” at the 252nd American Chemical Society Meeting in Philadelphia. This exciting experience has allowed me to learn from other professionals in the field, receive constructive feedback on my research, and expand my professional network. I am also sincerely thankful to the officers of the Toxicology Division for awarding me the 3rd place poster award, and I look forward to attending future ACS meetings.

    Byeong Hwa Yui

    (1st Place Postdoctoral Poster Presentation Awardee)
    I am a research associate and a lab manager in the laboratory of Dr. Robert Turesky, housed in the Masonic Cancer Center at University of Minnesota (Twin Cities). I received my PhD in Chemistry from New York University under the supervision of Prof. Nicholas E. Geacintov. My doctoral research interests were focused on the mechanisms of oxidative DNA damage by photo-irradiation and developing liquid chromatography-mass spectrometry techniques to measure the oxidative DNA adducts formed by carcinogens and reactive oxygen species.

    My current research involves the biomonitoring of DNA adducts of carcinogens in human cohorts. I have developed a long sought mass spectrometry method to measure DNA adducts in formalin-fixed paraffin-embedded (FFPE) tissues, a largely underutilized biospecimen for DNA adduct biomarker research. Our methodology was successfully applied to measure DNA adducts of multiple classes of carcinogens, including aristolochic acid, aromatic amines, heterocyclic aromatic amines, polycyclic aromatic hydrocarbons, and N-nitroso compounds. However, the isolation of DNA from FFPE tissues is a major bottleneck in the analysis of DNA adducts. Recently, our group developed a rapid throughput method to isolate DNA from FFPE tissues that increases the sample processing rate by 8-fold over manual methods at a similar cost of consumable reagents and comparable quality of DNA. Our rapid throughput DNA isolation method can be implemented in large scale studies designed to assess the role of exposures to hazardous chemicals and their DNA adducts in the etiology of cancer.

    I am very grateful to the Division of Chemical Toxicology of the ACS for their recognition of our work and awarding me the best poster award at 252th ACS National Meeting. It is my great honor to communicate and build networks with members of TOXI Division. I am looking forward to participating in future ACS meetings.

    (2nd Place Postdoctoral Poster Presentation Awardee)
    I received my Ph.D. degree in Analytical Chemistry from the Department of Chemistry at the University of Minnesota. Currently, I am a research associate in the laboratory of Dr. Stephen Hecht at the University of Minnesota. My research in the Hecht lab has been focused on studying the metabolic activation and DNA modification by carcinogens in tobacco products and the human environment. Using mass spectrometry, I am responsible for developing analytical methods for the quantitation of DNA adducts and detoxification urinary metabolites in laboratory animals and humans.

    I had a wonderful experience presenting my recent work on the “analysis of enantiomeric composition of N’-nitrosonornicotine in the urine of cigarette smokers and smokeless tobacco users” in the Division of Chemical Toxicology at the 252nd American Chemical Society National Meeting. It was a great opportunity to receive feedback and exchange ideas with graduate students, postdocs and professors. I was excited to win the 2nd place of the best postdoc poster awards, and I am looking forward to the next ACS meeting.

    Roman Hillebrand

    (3rd Place Postdoctoral Poster Presentation Awardee)
    I am a postdoctoral fellow in Prof. Peter Dedon’s lab in the Bioengineering Department at MIT. I received my Ph.D. in Chemistry at the University of Missouri – Columbia under Prof. Kent S. Gates’ supervision. My dissertation focused on the development of exo-affinity labeling agents for Tyrosine-protein phosphatase non-receptor type 1.

    My current research focuses on mass spectrometry methods for discovering novel DNA and RNA damage products and modifications. These methods combine the sensitivity of multiple reaction monitoring (MRM) with the discovery power of MS scanning to systematically search for unknown 2-deoxynucleoside structures in enzymatic hydrolysates of DNA. Applying this approach to DNA isolated from rats, we found a variety of previously undescribed DNA damage products in different tissues. The structures of these novel 2-deoxyribonucleosides are currently being established. Stepped MRM also revealed age-dependent increases in a previously described adduct, N2-carboxymethyl-dG (CMdG), in liver. CMdG is known to arise from reactions of DNA with glyoxal, the ubiquitous dialdehyde derived from oxidation of glucose, proteins and lipids, and is involved in formation of advanced glycation end-products associated with chronic diseases. This approach thus provides a means to identify the DNA damage products and modifications that truly matter in normal development and tissue-specific pathophysiology of aging.

    ACS meetings are always fun and helpful in broadening your horizons and engaging with other researchers. I am grateful to the officers of the Division for 3rd place in the postdoctoral poster awards.
