    非洲爪蟾卵母細胞內的螺旋鈣波和靶波
  15. In xenopus embryonic extracts camp concentration and pka activity also oscillations accompany with the cell cycle, low in mitosis and increased during m / g1 transition, keep high until next mitosis, and the mechanism concern with the cdc25 phosphorylation state and cyclin b concentration. mouse fertilized egg is the most simple and natural model for cell cycle that near to human, but little is know about pka on mpf also pka on mitosis

    通過對非洲爪贍胚胎細胞周期的研究發現jka活性也隨細胞周期變化而波動，在m期出現時pka活性下降，而m間期轉換時pka活性達最大值，一直維持高值直到下一個m期出現，其對mpf活性調節與cdc25磷酸化狀態及周期素b表達有關。
  16. An improved method of the preparation of xenopus oocytes for gene expression of ion channels

  17. A critical and central component is likely to be mpf ( m - phase promoting factor, another name is maturation - promoting factor, it was first discovered by masui and marikert in 1971, and then purified from xenopus laevis eggs in 1988

    P34 ~ （ cdc2 ）有三個重要調節位點thr14 、 tyr15和thr161分別被其他各種因素調節，當thr161處于磷酸化，而thrl4 、 tyrls處于脫磷酸化時， p34拋才能被激活。
  18. Mpf is a complex that consists of the protein kinase p34cdc2 and the regulatory protein cycli b ; the protein kinase activity of p34cdc2 is strictly dependent on its association with cyclinb. in xenopus laevis eggs the absent of cyclin b, mpf will not be activited

    Ca卜活化p34 」擬的機制第一步是結合cycinb ，並且處于磷酸化狀態，即thr14 、 tyrls和tlirl61都處于磷酸化狀態；第二步是cdc25磷酸酶通過是thr14 、 tyr15脫磷酸化而激活p34 」擬。
