The role of glycogen synthase kinase-3 (GSK-3) in the nitric oxide-guanosine 3',5'-cyclic monophosphate (NO-cGMP)-induced isoflavone production in soybean sprouts was examined. Inhibitors and donors of NO, cGMP, and GSK-3 inhibitor were added to UV-B irradiated sprouts. Results showed that NO, with cGMP, induced the expression of GSK-3 under UV-B radiation. Protein kinase G (PKG) was shown to be involved in NO-cGMP-induced GSK-3 activation. GSK-3 elevated activity and expression levels of chalcone synthase (CHS) and isoflavone synthase (IFS), and increased isoflavone accumulation.
研究了一氧化氮-鸟苷 3',5'-环单磷酸（NO-cGMP）诱导大豆芽中异黄酮产生过程中糖原合成酶激酶-3（GSK-3）的作用。向 UV-B 辐射的豆芽中添加了 NO、cGMP 和 GSK-3 抑制剂的抑制剂和供体。结果表明，NO 与 cGMP 在 UV-B 辐射下诱导 GSK-3 的表达。显示蛋白激酶 G（PKG）参与 NO-cGMP 诱导的 GSK-3 激活。GSK-3 提高了查尔酮合酶（CHS）和异黄酮合酶（IFS）的活性和表达水平，并增加了异黄酮的积累。
