Transfection-mediated cell synchronization: acceleration of G1-S phase transition by gamma irradiation
1Tulane Health Sciences Center, New Orleans, LA 70112, USA.
Abstract:
We have previously provided evidence that the uptake of DNA into cells is cell cycle specific following transfection. We show here that, immediately after transfection, successfully transfected cells are greatly enriched for cells in early G1 or G0 phase and that, upon removal of the DNA precipitates, cells progress through G1 and enter S phase in a synchronous fashion. We also demonstrate that this approach can be utilized in meaningful cell-cycle experiments, and we show that gamma irradiation accelerates the G1-S phase transition in a cell line with a functionally inactive p53 protein.
