Four transgenic founder mice were produced that carry the adenovirus E1A gene under control of the human red pigment promoter. Two of the founder animals passed the transgene to progeny, and one line was bred to homozygosity. The line of mice homozygous for the transgene expressed E1A-specific RNA at a low level in their eyes; no expression could be detected in other tissues that were tested. Either the founder animals or their progeny exhibited developmental abnormalities of their eyes, including a small eye phenotype, retinal dysplasia, anterior cleavage syndrome, and retinal pigment epithelium dysplasia. Individuals from the same line of mice exhibited subsets of the abnormalities, e.g., many animals had one normal size eye and one small eye, even though both eyes contained E1A-specific RNA. No tumors resulted from E1A expression in animals monitored for 22 months.
