Differential expression of inflammatory responsive genes between chronic periodontitis and periodontally affected bronchiectasis patients.

Abstract

The study aimed to investigate differential expression of targeted inflammatory-immune responsive genes [LTA, LTB, TNFSF4, TNFSF11/RANKL, TNFSF13, TNFSF13B, TNFRSF11B/ Osteoprotegerin; OPG and GFPT1/GFA ] in gingival tissues of bronchiectasis patients having chronic periodontitis in North central Indian population. Gingival tissues were collected from 30 systemically healthy chronic periodontitis patients (CP), 30 bronchiectasis patients with chronic periodontitis (B+CP), 3 systemically healthy with healthy gingiva (healthy control; HC) and 3 bronchiectasis with healthy gingiva (bronchiectasis control; BC). Statistical analysis revealed 7 genes to be significantly upregulated on comparing CP with B+CP i.e LTA (P<0.0001) in B+CP while LTB (P<0.0001), TNFSF4 (P=0.0003), TNFSF11 (P<0.0001), TNFSF13 (P=0.0003), TNFSF13B (P<0.0001) and TNFRSF11B (P=0.0004) in CP group. LTA (Lymphotoxin A) gene could be a potential genetic marker in bronchiectasis patients with chronic periodontitis.
