Background

Luísa Camacho received a bachelor’s in applied plant biology from the Faculty of Sciences of the University of Lisbon, Portugal in 1998, and a Ph.D. in cell biology from the University of Lisbon, Portugal in 2003. She was a research associate at the School of Biological and Biomedical Sciences of the University of Durham, UK between 2003 and 2005. She was an academic visitor at the Department of Plant Sciences of the University of Oxford, UK between 2005 and 2007. In 2007, Dr. Camacho joined NCTR’s Division of Biochemical Toxicology as a postdoctoral fellow; she converted to an FDA Staff Fellow in 2009. Dr. Camacho has published over 25 research articles and book chapters. She is a member of the editorial board for the journal Data in Brief and has served as a reviewer for more than 25 scientific journals.

Research Interests

Dr. Camacho’s group conducts toxicological studies in animal models to assess the toxicity of products of interest to FDA. A particular focus has been on compounds with endocrine activity and on toxicological studies that include exposures during the perinatal period of life. In addition to the traditional toxicological endpoints, she assesses molecular endpoints using biological samples collected from the same animals. This complementary effort contributes to a better understanding of the molecular mechanisms by which the compounds may act and helps identify potential novel biomarkers of toxicity. Many of these studies are conducted under the sponsorship of the National Toxicology Program (NTP) and/or conducted in collaboration with colleagues from other divisions at NCTR and from the FDA product centers. Dr. Camacho has multiple major research interests. The first of these is CLARITY-BPA (Consortium Linking Academic and Regulatory Insights on Bisphenol A Toxicity), a collaborative research program that involves staff from FDA (NCTR and Center for Food Safety and Applied Nutrition), National Institute of Environmental Health Sciences (Division of Extramural Research and Training and NTP), and 13 university-based researchers. Next, there is the characterization of the fibrinolytic activity of the dietary supplements nattokinase and lumbrokinase in vitro and assessment of their toxicological effects, either individually or in combination with aspirin, in vivo using a rat model. Finally, Dr. Camacho retains an interest in comparison of the dose-response and temporal dynamics of traditional (blood urea nitrogen and serum creatinine) and novel (serum microRNAs) biomarkers of nephrotoxicity upon a combined exposure to melamine and cyanuric acid in rats.
