Popis: The fruit of Ziziphus jujuba Mill., known as jujube or Chinese date, is commonly consumed as a health supplement worldwide. To study the role of jujube in brain benefits, the expression of neurotrophic factors and anti-oxidant enzymes in the jujube-treated cultured astrocytes was determined. Application of a chemical standardized water extract of jujube in cultured astrocytes for 24 h stimulated the expressions of nerve growth factor, brain-derived neurotrophic factor and glial cell line-derived neurotrophic factor in a concentration-dependent manner. The pre-treatment with H89, a protein kinase A inhibitor, attenuated the jujube-induced expression of neurotrophic factors. In parallel, the treatment of jujube water extract induced the transcriptional expressions of the enzymes responsible for anti-oxidation, i.e.quinine oxidoreductase 1, glutamate-cysteine ligase catalytic subunit, glutamate-cysteine ligase modifier subunit and glutathione S-transferase, in a concentration-dependent manner. These results proposed the benefits of jujube in regulating expressions of neurotrophic factors and anti-oxidant enzymes in cultured astrocytes.
