Increased type IV collagenase in lgl-induced invasive tumors of Drosophila

Loss of function mutations in the lethal giant larvae (lgl) gene causes neoplastic brain tumors in Drosophila. We have introduced a lacZ reporter gene into lgl mutant cells and used beta-galactosidase expression as a marker to monitor the growth of such tumors following transplantation into wild-typ...
