While ATOH1 CDXs expressed neither ASCL1 nor POU2F3 (Figure 1A), ATOH1 was expressed alone (CDX17P) or in combination with NEUROD1 at the transcript (Figure 1A) and protein levels (Figure 1C; CDX25, 78% positive tumor cells; CDX30P, 78% positive tumor cells; CDX17, moderate NEUROD1 expression, 30% positive tumor cells). This evidence concerns the gene NEUROD1 and neoplasm.
