Abstract
A depletion method to inhibit tumor growth includes introducing a viral expression system capable of expressing methioninase or a fusion protein containing methioninase into a tumor contained in a vertebrate subject or cells thereof. The fusion protein may contain a fluorescent protein to permit monitoring of the completeness of the depletion method. The fusion protein can be used in vivo as well as in vitro screening protocols which employ the viral expression system. The expression system includes control sequences and means to integrate the nucleotide sequence into the genome of a host cell for expression. The method may also include treating the cells with isolated methioninase and/or with a therapeutic cell. The depletion method can be with other known therapies, such as maintaining the animal having the tumor on a methionine depleted diet.
