Increased Advanced Oxidation Protein Products Generation by Cyclosporine-A and Angiotensin II in Human Gingival Fibroblasts – Ex-vivo Study
Journal Title: Journal of Clinical and Diagnostic Research - Year 2017, Vol 11, Issue 1
Abstract
Introduction: Cyclosporin-A (CsA), an immunosuppressant, induces renal fibrosis and Renin Angiotensin System (RAS) is known to play a major role. CsA has the potential to increase the oxidative stress; specifically through the Advanced Oxidation Protein Products (AOPP) which could possibly stimulate fibrosis. A similar type of pathology occurs even in the gingiva known as CsA Induced Gingival Overgrowth (CIGO). Aim: This study was undertaken to estimate the AOPP generation by Human Gingival Fibroblasts (HGF) under the influence of CsA and Angiotensin II (Ang II). Materials and Methods: Six healthy gingival tissue samples were obtained during crown lengthening procedure and primary HGF were cultured using enzymatic digestion method. The ideal non-cytotoxic concentrations of CsA and Ang II were identified using cytotoxicity assay. Later, HGF were incubated with CsA and Ang II for 12 hours and AOPP assay was performed at zero and one hour interval. Results: There was a statistically significant increase in AOPP production in both the CsA and Ang II when compared to the control group with a p value<0.05. Conclusion: CsA can induce oxidative stress and preventing/ controlling it may be necessary to prevent untoward effect of the drug.
