OverviewAI-generated summary

Brittni P. Littlejohn's research investigates the influence of environmental factors and physiological states on animal health, with a particular focus on molecular mechanisms. Her work has explored the impact of stress and nutrient availability on gene expression and DNA methylation patterns in cattle and pigs. She has examined the effects of gossypol from cottonseed meal on growth performance and blood parameters in growing pigs, as well as the potential of melatonin supplementation to influence uterine and artery hemodynamics in beef cows grazing endophyte-infected tall fescue. Furthermore, Littlejohn has studied the use of DNA methylation patterns from peripheral blood leukocytes as potential biomarkers for stress axis tissues in Brahman cows and investigated the influence of prenatal stress on amygdala tissue in these animals. Her collaborations include extensive work with Jeremy G. Powell, C.R. Looney, E. B. Kegley, and Doug L. Galloway at the University of Arkansas at Fayetteville, with whom she shares multiple publications.
