Andrew McCallion Laboratory
The McCallion Laboratory studies the roles played by cis-regulatory elements (REs) in controlling the timing, location and levels of gene activation (transcription). Their immediate goal is to identify transcription factor binding sites (TFBS) combinations that can predict REs with cell-specific biological control--a first step in developing true regulatory lexicons. As a functional genetic laboratory, we develop and implement assays to rapidly determine the biological relevance of sequence elements within the human genome and the pathological relevance of variation therein. In recent years, we have developed a highly efficient reporter transgene system in zebrafish that can accurately evaluate the regulatory control of mammalian sequences, enabling characterization of reporter expression during development at a fraction of the cost of similar analyses in mice. We employ a range of strategies in model systems (zebrafish and mice), as well as analyses in the human population, to illuminate the genetic basis of disease processes. Our long-term objective is to use these approaches in contributing to improved diagnostic, prognostic and therapeutic strategies in patient care.
