Oxidative stress, glutathione, and gene expression as key indicators in SH-SY5Y cells exposed to zearalenone metabolites and beauvericin.
2020
The co-presence of mycotoxins from fungi of the genus Fusarium is a common fact in raw food and food products, as trace levels of them or their metabolites can be detected, unless safety practices during manufacturing are carried out. Zearalenone (ZEA), its metabolites α-zearalenol (α-ZEL) and β-zearalenol (β-ZEL) and, beauvericin (BEA) are co/present in cereals, fruits or their products which is a mixture that consumer are exposed and never evaluated in neuronal cells. In this study the role of oxidative stress and intracellular defense systems was assessed by evaluating reactive oxygen species (ROS) generation and glutathione (GSH) ratio activity in a human neuroblastoma cell line, SH-SY5…
Protective Effects of the Hydroethanolic Extract of Fridericia chica on Undifferentiated Human Neuroblastoma Cells Exposed to α-Zearalenol (α-ZEL) an…

Fridericia chica (Bignoniaceae) is a traditional medicinal plant. The aim of this research was to determine the protective effects of the hydroethanolic extract from the F. chica leaves (HEFc) against the cytotoxicity of zearalenone (α-ZEL) and β-ZEL on SH-SY5Y cells. Free radical scavenging activity of HEFc was evaluated using the DPPH method. The cytotoxicity of both zearalenone metabolites and HEFc was examined using MTT test, as was the cytoprotective effects of the HEFc on cells treated with these mycotoxins. The chemical composition of HEFc was determined using UPLC-QTOF-MS/MS. HEFc elicited good DPPH radical scavenging activity following a concentration-dependent relationship. Cells …
