2 Core Members Glenn Talaska, Ph.D., CIH, Core Leader Marian Miller, Ph.D., Imaging Head Stacey Andringa, RA2, Imaging and Analysis Consultative Resources: Robert Bornschein, Ph.D. Scott Clark, Ph.D., CIH Carol Rice, Ph.D., CIH Howard Shertzer, Ph.D. David Warshawsky, Ph.D. CEG Biomonitoring and Imaging Facilities and Services Core

3 Services Consultation, Analysis and Training Related to: DNA Adduct Analysis (Talaska, Warshawsky) Carcinogen Metabolites (Warshawsky, Talaska) Radical/Electrophile Scavenger and Enzyme Assays (Shertzer) Mass Spectroscopy Referral (Warshawsky) Imaging and Histological Phenotyping (Miller) CEG Biomonitoring and Imaging Facilities and Services Core

4 Services (Cont.) Consultation Regarding: Review and Critique Exposure Assessment Strategies (Rice, Bornschein, Clark, Talaska) Selection of Exposure Metrics (Rice, Clark, Talaska) Exposure Reconstruction (Rice) Review Exposure Data (Rice, Talaska) Biological Monitoring (Talaska) CEG Biomonitoring and Imaging Facilities and Services Core

5 Biomarkers in human and animal studies can: 1.Reduce Misclassification 2. Document the extent of effect modification 1.Exposure : Exposure Interactions 2.Gene : Exposure Interactions 3. Determine Mechanisms 4. Serve as outcome variables
