Research Statement

Dr. Omar Shakeel's research interest includes better understanding the environmental determinants of pediatric cancers. The incidence of pediatric cancers has steadily increased since 1975, which could suggest that other exogenous factors are accounting for an increasing proportion of cases. There has been growing concern over environmental exposures (e.g., toxicants) on the development of pediatric cancers. Unfortunately, identifying environmental determinants of childhood cancer has been challenging because there are currently no existing biomarkers to measure how various exposures co-occur and jointly influence pediatric cancer risk. There is growing evidence that primary teeth serve as a stable repository for exposures during development and early childhood. This novel biomarker has the potential to uncover the etiological mechanisms of cancer types, bridge the gap of understanding gene-environment interactions on the development of pediatric cancers, and profoundly impact the discovery of preventative strategies. We plan to measure multiple exogenous and endogenous factors in tooth layers corresponding to specific life stages in pediatric patients with acute lymphoblastic leukemia (ALL).
