“…18,20 Early somatic cell fusion experiments proved that G 0 cells actively synthesize endogenous cell cycle inhibitors that prevent the onset and progression of G 1 . 43 These studies also demonstrated that growth factors signal G 0 exit and transit of cells through G 1 by reprogramming the cellular metabolic machinery toward production of moieties neutralizing the G 1 inhibitors in G 0 cells and promoting the G 0 -to-S transition. Later work unveiled the molecular identity of these moieties: progression through G 1 and initiation of DNA synthesis are cooperatively driven by cyclin-dependent kinases (CDKs), whose activities are kept in check by CDK inhibitors.…”

“…В литературе имеются сведения о том, что на модели гетерокарионов удается обнаружить не только позитивное, но и негативное влияние на синтез ДНК в ядрах. При слиянии с клетками, находящимися в искусственно вызванном состоянии покоя [7][8][9] или с прекратившими пролиферацию диплоидными фибробластами поздних пассажей [7], вступление ядер пролиферирующих клеток в фазу синтеза ДНК угнетается. Можно было предположить, что и терминально дифференцированные клетки способны угнетать синтез ДНК в гетерокарионах.…”
