Although the other 19 nodes (i.e., GATA2, ETS1,YBX1, AR, FOXP3, GATA1, SP1, E2F4, PRDM14, ARNT, MIA3, JUN, CREB1, FOS, STAT1, CEBPA, AHR, E2F1, PAX5, and Pax-5) except FOS were not differentially expressed in pulpitis, they still play critical roles in the pathogenesis of pulpitis by interacting and regulating DEGs that are expressed in pulpitis. This evidence concerns the gene ARNT and pulpitis.
