Our interests are in the development of transgenic technologies for genetic modification of the chicken and the applications of these technologies. We have developed an efficient method for production of transgenic chickens using lentiviral vectors (McGrew et al. 2004) and are interested in applying this technology and extending it so that we have the same tools for studying the chick as are available in the mouse. The chick is an excellent model for the study of vertebrate development and we have generated a transgenic line that expresses GFP at high levels in all cells of the developing embryo. These embryos can be used in grafting experiments for lineage analysis during embryogenesis. We are extending this approach by developing additional fluorescent reporter lines and by using transgenesis to study specific aspects of development (e.g. sex determination, see Clinton lab page).
There are many other potential applications of transgenesis in the chicken, particularly in the study of disease in poultry and in biotechnology. We are developing RNA interference strategies to investigate viral pathogenesis and model the potential for producing resistance to infection by specific pathogens. We have recently shown that therapeutic proteins can be synthesised as a component of egg white, using transgenes derived from regulatory sequences of the ovalbumin gene (the major egg white protein gene) and human βinterferon (Lillico et al., 2007).
