Image Caption An analysis of accelerated evolution in species with highly distinctive traits reveals candidate functional genomic elements for shaping somatic mutation rate, cancer risk, digit development, immunity, glaucoma, pigmentation, and other clinical phenotypes.
Description An important area of research involves learning how the expression of our genes influences health and disease risks. The parts of the genome that regulate gene expression are cis-regulatory elements. Gregg and colleagues took an unusual approach to discover these cis-regulatory elements by analyzing the genomes of species that evolved disease resistance "superpowers". For example, elephants have large bodies with many cells and have evolved unique mechanisms to prevent cancer. By comparing the elephant genome to smaller, less cancer-resistant species, they uncovered putative master cis-regulatory elements in the genome that shape mammalian cancer resistance. In a separate study, they studied hibernating mammals that have evolved unique controls over metabolism, obesity and aging. By comparing their genomes to non-hibernating species, they found cis-regulatory elements that are putative master regulators of mammalian obesity, feeding, metabolism and aging. In total, the Gregg lab has analyzed the genomes of over ten species with different biomedical superpowers, creating an atlas of cis-regulatory elements linked to clinically important phenotypes.
