http://purl.uniprot.org/citations/23722449 | http://www.w3.org/2000/01/rdf-schema#comment | "Objective and designThis study evaluated the effect of an antioxidant, Vitamin E, on cultured chondrocytes against H₂O₂-induced damage in vitro.MaterialRat chondrocytes isolated from articular cartilage.TreatmentChondrocytes were pretreated with either 50 or 100 μM Vitamin E or serum-free medium for 24 h followed by their exposure to 200 μM H₂O₂ for 3 h. Chondrocytes without exposure to H₂O₂ served as control group.MethodsThe effect of Vitamin E pretreatment was evaluated by examining proteoglycan contents, nitrite levels, viability, apoptosis, and senescence of cultured chondrocytes.ResultsProteoglycan contents increased in groups treated with Vitamin E. Semi-quantitative real-time PCR data also correlated with these results and demonstrated that Vitamin E up-regulated expression of Agc1, Col2a1, and PCNA genes along with down-regulation in the expression of Col1a1 and Casp3 genes. The differentiation index improved after Vitamin E pretreatment. Nitrite levels were reduced with a corresponding increase in cell viability. Reduction in apoptosis and senescence was also observed after Vitamin E pretreatment. Moreover, a dose-dependent effect of Vitamin E was seen. In contrast to 50 μM Vitamin E, 100 μM was more potent in inducing protection of chondrocytes from H₂O₂-induced oxidative damage.ConclusionVitamin E reversed the oxidant-induced alterations in chondrocytes and may be a good option to pretreat chondrocytes before transplantation."xsd:string |
