Abstrakt: Flavonoids, considered as phytoestrogen mainly deriving from fruit and vegetable, are known to have beneficial effects in brain functions. The role of flavonoids in induction of a cholinergic enzyme, acetylcholinesterase (AChE), was being explored here. In cultured PC12 cells, twenty-four commonly found flavonoids were tested for its induction on AChE activity. Fourteen flavonoids showed induction, and five of them had robust effect, i.e. daidzin, alpinetin, irisflorentin, cardamonin and lysionotin. The induction of AChE was fully blocked by pre-treatment of G15 (a selective G protein-coupled receptor 30 [GPR 30] antagonist), suggesting a direct involvement of a membrane-bound estrogen receptor, named as GPR 30, in the cultures. In addition, daidzin was further identified to induce expression of tetrameric globular form of proline-rich membrane anchor (PRiMA)-linked AChE. In parallel, application of daidzin in cultured PC12 cells significantly induced expression of neurofilaments, markers for neuronal differentiation. Taken together, flavonoids could induce the expression of AChE via GPR 30 in cultured PC12 cells, which could be a good candidate for possible treatment of the brain diseases.
