ATOH1 and neoplasm: We selected the co-expressed genes with the highest correlation between DEFA5 and DEFA6 (Figure 8C): KLK12, PTGDR2, ATOH1, OLFM4, and CLCA1, which are successively involved in tumorigenesis, inflammatory response, transcriptional regulation, inhibition of cell growth, induction of cell differentiation and apoptosis, and promotion of cell adhesion and tumor inhibition.
