Improving health for older populations

Undergrad researchers join redox biologist Tinna Traustadóttir in a clinical study of broccoli-based interventions for healthier aging.

A new study led by NAU Associate Professor Tinna Traustadóttir is investigating the relationship between aging, exercise, and phytonutrients—nutrients found in plants such as broccoli. Paradoxically, her team includes undergraduates from a decidedly younger population.

Does exercise + phytonutrients = healthy aging?

Yasmin and Ellaine presented their preliminary data on the effects of Astaxanthin supplementation on global thiol oxidation and stimulated antioxidant gene expression at the AZ PS 2021 Annual Meeting held in person at Midwestern University in Glendale, AZ.  They received the top award in the undergraduate category. Ellaine is funded by LSAMP and HURA and Yasmin is funded by RISE and LSAMP. Congratulations to Yasmin and Ellaine!

This summer we moved the wet lab (and Dr. T’s office) to the Wettaw building, second floor. The room number for the lab is #233 and the office is directly across the hall in room #235. The clinical lab remains in the Bio building, room #121.

Ethan Ostrom completed his Ph.D. and graduated in the spring of 2021. He has started a post-doctoral fellowship at the University of Washington in Seattle and received an F-32 training grant from the National Institute on Aging. Please join us in congratulating him and wish him all the best in his post-doc.

The first paper from the 3 year study on exercise training and redox balance was recently published in Free Radical Biology and Medicine (see our publications page). This study was an 8-week randomized controlled where young and older individuals were randomly assigned to either exercise training or a non-exercise control group. The primary outcome tested whether the exercise intervention would improve Nrf2 activation and signaling in response to acute exercise. The two main findings were i) the exercise… Read more

Dr. Traustadóttir was among the 40 recipients of the Women in Research Award granted by Cayman and CABRI.  “The company planned to award five well-qualified applicants,” said Dr. Kirk Maxey, President and CEO of Cayman. “But the applicant pool was so impressive, we extended the award to forty women who are working to answer essential research questions. Reviewing the value of the contributions these women are making to scientific discovery has made us optimistic for overcoming the many challenges… Read more
