Research Overview
Dr. Laura James’ research focus is on mechanisms and pathways of recovery in the liver following acetaminophen toxicity in the mouse. In September 2007, the National Institute of Diabetes and Digestive Disease (NIDD) awarded her an R01 grant to examine the role of hypoxia inducible factor 1 alpha and VEGF in repair processes in the mouse liver after toxic dosing of acetaminophen. Dr. James is also interested in the development of assays for measuring biomarkers of acetaminophen toxicity in clinical samples from patients with acute acetaminophen overdose and liver failure and in patients receiving therapeutic exposures to acetaminophen. She currently serves as the Principal Investigator for the Arkansas Children’s Hospital PPRU. The PPRU is one of 13 centers nationally participating in the Network of Pediatric Pharmacology Research Units funded by the National Institute of Child Health and Human Diseases.
