The tested genotypes were Me; l(3)mbn1, in which the l(3)mbn tumor suppressor gene is mutant, Me,hopTum, carrying constitutively active allele of hopscotch (hop), and Me; Hml>Pvrλ, where the constitutively active form of the receptor tyrosine kinase Pvr is expressed with the hemocyte specific Hemolectin (Hml-Gal4) driver [4,30,31,42]. Here, PVR is linked to neoplasm.
