Overexpression of ato, or its mouse ortholog Atoh1 (Ensembl: ENSMUSG00000073043)—but not a green fluorescent protein (GFP) control transgene—in the eyeful background almost completely suppresses the formation of eye tumors (Figure 1B (ato): 2%, p < 0.0001, n = 118; Figure 1C (Atoh1): 1%, p < 0.0001, n = 98; GFP (unpublished data): p = 0.25; Figure 1I). This evidence concerns the gene ATOH1 and eye neoplasm.
