Abstract

Chinese hamster pulmonary fibroblasts (V79 cells) pre-treated with flax fabrics derived from non-modified or genetically engineered flax fibres and treated with H2O2 revealed a markedly lower level of intracellular reactive oxygen species (ROS) than control, non-pre-treated cells. The fabrics were prepared from fibres derived from two kinds of transgenic plants: W92 plants, which overproduce flavonoids, and M type plants, which produce hydroxybutyrate polymer in their vascular bundles and thus in fibres. Incubating the V79 cells with the flax fabrics prior to H2O2 treatment also reduced the amount of DNA damage, as established using the comet assay (also known as alkaline single-cell gel electrophoresis) and pulsed-field electrophoresis of intact cellular DNA. Selected gene expression analysis revealed the activator impact of fabrics on the apoptotic (BCL2 family, caspases) gene expression. This promoting activity was also detected for histone acetyltransferase (HAT; MYST2) gene expression. The flax fabric derived from both GM flax plants exhibited a protective effect against oxidative stress and ROS-mediated genotoxic damage, but the W92 fabric was the strongest. It is thus suggested that these fabrics might be useful as a basis for new biomedical products (e.g. wound dressings) that actively protect cells against inflammation and degeneration.
