tRNAs as uncharacterized, functioning biomarkers in acute respiratory distress syndrome (ARDS)

tRNAs are increasingly acknowledged as essential regulators in various human diseases; however, their role in critical illness has yet to be explored.

Molecular profiling of individuals with critical illnesses

We utilize our extensive ICU biorepository, which includes longitudinal samples from critically ill patients, to elucidate disease mechanisms and discover new targets for further research.

Protein degradation in ARDS and sepsis

Ubiquitination is a universal molecular modification that tags proteins for degradation and governs vital cellular processes, such as cell death and responses to environmental stimuli.

Joseph S. Bednash, MD

Dr. Bednash is an Assistant Professor of Pulmonary and Critical Care Medicine and the Assistant Director of the Acute Lung Injury Center at the Ohio State University. Clinically, he is an attending physician in the Medical Intensive Care Units and Pulmonary Consult services at the Ohio State University Wexner Medical Center and James Cancer Hospital.

In his research laboratory, Dr. Bednash studies how transfer RNAs (tRNAs) influence the development and resolution of critical illness syndromes, such as acute respiratory distress syndrome (ARDS) and sepsis. His research efforts are funded by the National Institutes of Health (NIH), the American College of Chest Physicians (CHEST), as well as support from his institution.

The Bednash lab focuses on collaborative scientific endeavors through joint projects within the Acute Lung Injury Center at Ohio State, while also providing training for aspiring researchers.
