Abstract
Exploitation of the insulating properties of the complete chicken lysozyme gene domain may facilitate the production of transgenic chicken bioreactors with the capacity to deposit valuable proteins in the egg white. Chimeric genes consisting of the chicken lysozyme gene regulatory sequences and sequences encoding foreign proteins could be inserted randomly into the chicken genome and retain appropriate expression levels. The research reported here established that chicken lysozyme gene regulatory sequences can be used to direct the production and secretion of green fluorescent protein (used as a reporter protein) in transiently transfected chicken blastodermal cells. Attempts to verify these findings in transgenic hens are currently in progress. To provide a rapid means of generating constructs encoding other foreign proteins under the control of lysozyme gene regulatory sequences that can facilitate the secretion of heterologous proteins in vivo, a generic lysozyme gene regulatory scaffold was created using a poxvirus-mediated gene targeting system.
