The role of cdc 2 , cdc 25 and cyclin A genes in the maintenance of immortalization and growth arrest in a rat embryonic fibroblast conditional cell line . ^^^ The role of the cell cycle control genes cdc 2 , cdc 25 and cyclin A in the maintenance of immortalization and in growth arrest was examined in the tsa 14 , a SV 40 T antigen rat embryonic fibroblast conditional for growth cell line . ^^^ The ability of cdc 2 , or cdc 25 , or cyclin A genes to maintain the tsa 14 immortal phenotype was also examined by electroporations of these genes into the tsa 14 cells . ^^^ Clones over expressing the electroporated cdc 2 , or cdc 25 , or cyclin A , or combinations of these genes growth arrested at the non permissive conditions similar to controls , thereby suggesting that the expression of these genes alone is insufficient for tsa 14 maintenance of immortalization . . ^^^

In this study , we isolated cDNAs of starfish cyclin A and Cdc 2 , and monitored extensively the cell cycle dynamics of cyclin A and cyclin B levels and their associated Cdc 2 kinase activity , Tyr phosphorylation of Cdc 2 , and Cdc 25 phosphorylation states throughout meiotic and early embryonic cleavage cycles in vivo . ^^^ Cyclin B , but not cyclin A , associated Cdc 2 was subjected to regulation via Tyr phosphorylation , and phosphorylation states of Cdc 25 correlated with cyclin B / Cdc2 kinase activity with some exceptions . ^^^ Between meiosis 1 and 2 and at the pronucleus stage , cyclin A and B levels remained low , Cdc 2 Tyr phosphorylation was undetectable , and Cdc 25 remained phosphorylated depending on MAP kinase activity , showing a good correlation between these two stages . ^^^ In the first cleavage cycle , under conditions which prevented Cdc 25 activity , cyclin A / Cdc2 was activated with a normal time course and then cyclin B / Cdc2 was activated with a significant delay , resulting in the delayed completion of M phase . ^^^
