Abstract
INTRODUCTION Endothelin-1 (ET-1) is a potent vasoconstrictive peptide with multi functional activity in various systemic diseases. Previous studies indicate the detection of ET-1 in gingival tissues and gingival crevicular fluid. AIM The aim of this study was to estimate the serum ET-1 levels in clinically healthy subjects and subjects with chronic periodontitis, before and after treatment, and correlate it with the clinical parameters. MATERIALS AND METHODS A total of 44 patients were included in the study. Group I comprised of 20 subjects with clinically healthy periodontium. Group II comprised of 24 subjects with chronic periodontitis. Group III comprised of same Group II subjects following periodontal management. Serum samples were collected from the subjects and an Enzyme Linked Immunosorbent Assay (ELISA) was done to estimate the ET-1 levels. The ET-1 levels were then correlated among the three groups with the clinical parameters namely, Plaque Index (PI), Sulcus Bleeding Index (SBI), probing pocket depth, clinical attachment loss and Periodontally Inflamed Surface Area (PISA). The independent t-test and paired t-test were used for comparison of clinical parameters and Pearson's correlation coefficient test was used for correlating the ET-1 levels. RESULTS ET-1 levels in chronic periodontitis subjects were significantly higher compared to healthy subjects (p<0.001). However, the clinical parameters did not statistically correlate with the ET-1 levels. There was a significant decrease in ET-1 levels following treatment (p<0.001). CONCLUSION Serum ET-1 is increased in chronic periodontitis and reduces after periodontal therapy. Further studies are required to establish ET-1 as a biomarker for periodontal disease.

Abstract
Tn antigen (GalNAc-α-O-Ser/Thr), a mucin-type O-linked glycan, is a well-established cell surface marker for tumors and its elevated levels have been correlated with cancer progression and prognosis. There are also reports that Tn is elevated in inflammatory tissues. However, the molecular mechanism for its elevated levels in cancer and inflammation is unclear. In the current studies, we have explored the possibility that cytokines may be one of the common regulatory molecules for elevated Tn levels in both cancer and inflammation. We showed that the Tn level is elevated by the conditioned media of HrasG12V-transformed-BEAS-2B cells. Similarly, the conditioned media obtained from LPS-stimulated monocytes also elevated Tn levels in primary human gingival fibroblasts, suggesting the involvement of cytokines and/or other soluble factors. Indeed, purified inflammatory cytokines such as TNF-α and IL-6 up-regulated Tn levels in gingival fibroblasts. Furthermore, TNF-α was shown to down-regulate the COSMC gene as evidenced by reduced levels of the COSMC mRNA and protein, as well as hypermethylation of the CpG islands of the COSMC gene promoter. Since Cosmc, a chaperone for T-synthase, is known to negatively regulate Tn levels, our results suggest elevated Tn levels in cancer and inflammation may be commonly regulated by the cytokine-Cosmc signaling axis.

Abstract
BACKGROUND/PURPOSE Transforming growth factor-β (TGF-β) plays an important role in the pathogenesis of cyclosporine A (CsA)-induced gingival overgrowth (GO). Connective tissue growth factor (CTGF/CCN2) acts as a cofactor with TGF-β to induce the maximal profibrotic effects of TGF-β. We investigated the effects of CsA on CCN2 expression in human gingival fibroblasts (HGFs) and the potential chemopreventive agent for CsA-induced GO. METHODS Western blot analyses were used to examine the signaling pathways of CsA-induced CCN2 expression in HGFs and whether epigallocatechin-3-gallate (EGCG), curcumin, or lovastatin can inhibit CsA-induced CCN2 expression. RESULTS CsA significantly stimulated CCN2 synthesis in HGFs. This effect can be inhibited by c-Jun NH(2)-terminal kinase (JNK) and Smad3 inhibitors but not by TGF-β neutralizing antibody and TGF-β type I receptor inhibitor. Furthermore, EGCG completely blocked CsA-induced CCN2 expression. CONCLUSION CsA-induced CCN2 protein expression is mediated through JNK and Smad signaling. CsA may contribute to the pathogenesis of GO through upregulation of CCN2 expression in HGFs. EGCG could be an adjuvant for the prevention of CsA-induced GO.

Abstract
Cyclosporine-A (CsA) stimulates heme oxygenase-1 (HO-1) expression in the gingiva, but the regulation and the role of HO-1 in gingival overgrowth are not well-understood. HO-1 is regulated by several transcription factors, such as nuclear factor-κB (NF-κB) and nuclear factor erythroid-2-related factor 2 (Nrf-2). The aim of this study was to examine the role of Nrf-2 in the regulation of CsA-stimulated HO-1 expression in human gingival fibroblasts. Nrf-2 siRNA (siNrf-2), NF-κB, kinase inhibitors, and sulforaphane (SFN) were used to examine the nuclear translocation of Nrf-2 and expression of HO-1 and transforming growth factor-β1 (TGF-β1) in cells. Treatment with siNrf-2, but not with an NF-κB inhibitor, reduced CsA-stimulated HO-1 mRNA expression. ERK inhibition significantly decreased CsA-stimulated Nrf-2 nuclear translocation and HO-1 mRNA expression. Pre-treatment with SFN showed that HO-1 plays a role in attenuating CsA-mediated TGF-β1 expressions. These findings suggest that CsA-stimulated HO-1 expression is mediated through the activation of ERK, and that Nrf-2 plays a protective role against CsA-induced gingival fibrosis by modulating collagen turnover-related genes.
