Bio
Dr. Vorhees has served on numerous National Institutes of Health site visit committees, special emphasis panels, and ad hoc review committees since 1984, and was a regular member of a study section from 1994-1998, serving as interim chair in 1997. He has also reviewed grant applications for the National Science Foundation, Veterans Administration, Wellcome Trust, March of Dimes, and other agencies. He has served on advisory committees to the US Food and Drug Administration, US Environmental Protection agency, National Research Council, several private foundations, and a number of pharmaceutical companies.
Dr. Vorhees was Director of the Graduate Program in Molecular and Developmental Biology, University of Cincinnati College of Medicine, 1998-2004.

Research
Effects of amphetamines on brain development, behavior, and neurotoxicity; neurobiological substrates of learning and memory; proteins for neurotransmitter receptors, second messenger transduction, and regulators of signaling pathways.
Dr. Charles Vorhees' lab is pursuing two lines of research. One is on the prenatal effects of stimulant drugs of abuse on brain development and later learning and memory function. Dr. Vorhees' lab is the first to report that late, but not early, neonatal exposure to methamphetamine in rats (a period of brain development analogous to human third trimester) results in impaired spatial learning and memory, while sparing sequential and other forms of learning. This treatment also increases corticosterone dramatically. This was surprising because the effect occurs during the adrenocortical Stress HypoResponsive Period (or SHRP) stage of development.
Given this, the lab is examining methamphetamine treated offspring for the detailed pattern of how methamphetamine increases corticosterone at different developmental ages and what the effect is of single versus multiple doses. More recently, the findings with methamphetamine on learning have been extended to related substituted amphetamines, including ecstasy (MDMA) and fenfluramine. The lab has found that these drugs not only induce spatial learning and memory deficits similar to those seen with methamphetamine, they also induce impairments of sequential learning. Together, the data reveal previously unrecognized effects resulting from intrauterine exposure to substituted amphetamines and raise issues over the safety of dopaminergic and serotonergic-acting drugs on long-term brain development.
The second line of research uses gene targeting to disrupt genes whose protein products may be involved in learning and memory. The lab has created a knockout mouse with the calcium calmodulin phophodiesterase B1 gene disrupted (CAM PDE). Recent studies have shown that homozygotic mutants for this PDE (PDE1B) show no overt abnormalities, however, when assessed for spatial learning, they exhibit impaired learning. They also show changes in performance that vary as a function of the stimulus characteristic of the cues needed for successful spatial recall. The lab has also shown that mice with disruption of the DFF-45 gene, a recently identified gene involved in apoptosis and disrupted by Dr. Ming Xu, exhibit enhanced learning and memory. The lab is also behaviorally phenotyping other knockout mice in which genes expressed predominately in the brain are disrupted as part of a larger effort to understand the biological basis of learning and memory.
