Of note:

In a recent Nature Methods paper, Doug Taatjes, Ph.D., Director of the Microscopy Imaging Center, and the Center for Biomedical Shared Resources at the Larner College of Medicine, together with colleagues from the international consortium QUAREP-LiMi, proposed a set of standardized community-developed checklists to assist researchers, reviewers, and journal editors with the goal of increasing the clarity and reproducibility of image figures and their analyses. The hope is that many journals will adopt these guidelines as part of their “Instructions for Authors”—providing a succinct and easy to use checklist for authors when compiling images for reproduction and descriptions of image analyses performed.

Please join Dr. Vikas Anathy in congratulating Nicolas Chamberlain and Dr. Emily Nakada.

Nicolas Chamberlain a PhD student recently published a paper entitled “Lung epithelial protein disulfide isomerase A3 (PDIA3) plays an important role in influenza infection, inflammation, and airway mechanics” in the journal Redox Biology (PMID 30735910). His abstract to be presented at the American Thoracic Society (ATS) conference was chosen to receive an abstract scholarship. The scholarship includes a full in-training registration to the 2019 ATS International Conference in Dallas, Texas. 

Dr. Emily Nakada was a post-doctoral fellow in our group. Her manuscript entitled “Conjugated bile acids attenuate allergen-induced airway inflammation and hyperresposiveness by inhibiting UPR transducers” has been recently accepted in the journal JCI Insight.

A new study Yvonne Janssen-Heininger, Ph.D., professor of pathology and laboratory medicine, and colleagues published in Nature takes a deep dive into unraveling the oxidative vulnerabilities of each of the cysteines of glutaredoxin, which is important in protection from fibrosis but gets inactivated via oxidative mechanisms. The team leveraged computational chemistry approaches and experimental validation using a new assay specifically designed for this purpose. (8/2023- Larner College of Medicine Newsletter)

A very successful Inaugural Redox Biology and Pathology Retreat was held recently at the Courtyard Marriott in Burlington. The day resulted in new collaborations and connections spanning, medicine, biology, and chemistry. The images show attendees in the meeting space, our individual elevator pitch winners- Dr. Reem Aboushousha, Dr. Rob Hondal, and Maurice Newton, and our $15,000 research project design winning team.(6/2023)           

vandervliet-habibovic420x280A new study by Albert van der Vliet, Ph.D., professor of pathology and laboratory medicine, and a team of University of Vermont (UVM) researchers is honing in on why people with asthma often have worse symptoms if they are obese. This new research demonstrates that the gene DUOX1 likely contributes to the connection between obesity and asthma.  The research was published ahead of print in the American Journal of Physiology-Lung Cellular and Molecular Physiology and was highlighted as an APSselect article for March 2023. Albert van der Vliet, Ph.D., was the senior author on the paper, along with department of pathology and laboratory medicine coauthors Aida Habibovic, lab research technician;Litiele Cruz, Ph.D., visiting scholar; Vikas Anathy, Ph.D., associate professor; University Distinguished Professor Yvonne Janssen-Heininger, Ph.D.; and additional team members and authors from UVM.

Albert in JapanCongratulations to Dr. Albert van der Vliet, Ph.D., professor of pathology and laboratory medicine, for being selected as an Invited Fellow to Tohoku University in Sendai, Japan, to participate in research in the laboratory of Takaaki Akaike, M.D., Ph.D., professor of environmental medicine and molecular toxicology. The invitational fellowship relates to a Tohoku University initiative that allows Tohoku faculty members to host invited researchers to promote collaborative research in the host lab for up to three months. The objective is to promote joint publications and expand international collaborations. Dr. van der Vliet's visit coincided with a medley of scientific meetings and symposia collectively termed  Redox Week In Sendai 2022 and held October 27-November 1, 2022. The events brought together leading scientists from around the world in the specific research fields of nitric oxide biology, polysulfur biochemistry, and biology. Van der Vliet was co-organizer and speaker at one of the symposiums, and Yvonne Janssen-Heininger, Ph.D., and Brian Cunniff, Ph.D., both professors of pathology and laboratory medicine, also participated as invited speakers. Additional Japanese federal funding supports the exchange of invited researchers, graduate students, and post-doctoral scholars to collaborate on research. Read more about the redox research collaboration  between UVM and Tohoku University. (01/2023)
