Recent Grants:

  • NIH-SCORE, 2000-2003, $149,000. “Biological activity of secondary metabolites of American mistletoe,” PI: Kincaid; Research Assistant, A. Opler. This was preliminary support to see if mistletoe extracts from our southeastern United States species of mistletoe kill cancer cells in vitro and to test hypotheses about quality of biological activity of extracts relative to host tree species and other ecological factors. Results were not conclusive due to technical setbacks.
