Environmental factors that can affect gene expression. Exposing a fetus, infant, or child to a chemical or nutritional (or other) stressor during development can affect the risk of disease development even into adulthood. The mechanisms involved are probably epigenetics (Boekelheide et al. 2012).
The research program in the Laboratory of Receptor Biology and Gene Expression concerns the elucidation of mechanisms involved in the regulation of genetic expression in eukaryotic cells, and the identification of genes and regulatory processes involved in modulated states of expression during oncogenesis.he research program in the Laboratory of Receptor Biology and Gene Expression concerns the elucidation of mechanisms involved in the regulation of genetic expression in eukaryotic cells, and the identification of genes and regulatory processes involved in modulated states of expression during oncogenesis.
