In addition, periodontitis caused a significant increase in the NF-κB p65 levels in the nuclear fractions from of gingivomucosal tissues from operated rats (Figures 2(c) and 2(d)) compared to the gingivomucosal tissues from the contralateral side (Figures 2(c) and 2(d)). Here, NFKB1 is linked to periodontitis.
