A General Sight about Linking PARP-1 and NFKB1 Variations to the Inflammatory Events

Sultuybek GK, Yenmis G and Koc A

Poly (ADP-ribose) polymerase-1 (PARP-1) has various roles in cellular processes such as DNA repair, genomic stability, transcription, stress response, and cell death via regulating death and inflammation signalling pathways. On the other hand, PARP-1 inhibition has been shown to provide benefits in experimental models of animals with inflammatory diseases such as asthma, atherosclerosis and diabetes. PARP-1 also acts a transcriptional coactivator of nuclear factor kappa B (NFKB). The NFKB is a ubiquitous transcription factor that controls the expression of genes encoding cell adhesion molecules, growth factors, cytokines, and some acute phase proteins. Inappropriate activation of NFKB has been mostly searched with inflammatory events. In complete and persistent inhibition studies of NFKB, apoptosis, inappropriate immune cell development and delayed cell growth were investigated. These findings might provide new perceptions in the pathogenesis of inflammatory disorders regarding the roles of PARP-1 and NFKB1 proteins. In this review, we focus on some variations (rs28362491, rs696, rs1136410, rs2793378, rs7527192) of PARP-1 and NFKB1 genes in relation to susceptibility to common inflammatory diseases including rheumatoid arthritis, systemic lupus erythematosus, allergic rhinitis, Graves’ disease, Hashimoto’s thyroiditis, asthma and Behcet’s disease.
