The Effect of Protein Kinase B on the Expression and Location of p21 in Early Development of Mouse Fertilized Eggs
小鼠受精卵早期发育过程中PKB/Akt对p21蛋白表达及定位的影响

To investigate the effect of Protein kinase B on the expression and location of p21 in mouse early development. Immunopreciptation technology was used to detect the localization of p21 and Western blotting was used to analyze the expression of p21 after microinjecting mRNA of WT-PKB,myt-PKB and PKB-KD to mouse eggs. There was no obvious difference between the three kinds of mRNA in the expression of p21. But the cell localization altered. The p21 retain in cytoplasm after microjecting myt-PKB. In mouse fertilized egg PKB/Akt controls the cell cycle by changing the cell localization of p21.
