DNA repair in bleomycin-pretreated, permeable mouse sarcoma (SR-C3H/He) cells requires ATP for at least two steps, the repair DNA synthesis step and the repair patch ligation step. ADP can apparently replace ATP in both steps. Maximal, 1.5-2 fold stimulation of repair DNA synthesis was observed with
Effects of ATP and some other nucleotides (AMP, ADP, CTP, GTP, UTP and dATP) on reparative DNA synthesis and repair patch ligation in bleomycin-pretreated permeable mouse sarcoma cells were studied. Reparative DNA synthesis was significantly stimulated by 2.5 mM ATP, ADP or dATP. The stimulation was
The adenylate kinase (AK) isoforms network plays an important role in the intracellular energy transfer processes, the maintenance of energy homeostasis, and it is a major player in AMP metabolic signaling circuits in some highly-differentiated cells. For this purpose, a rapid and sensitive method
Specific chromosomes of sheep have been selectively "captured" in hamster x sheep cell hybrids produced by fusing different Chinese hamster auxotrophs with lymphocytes from sheep carrying normal or Robertsonian translocation chromosomes. A minipanel has been established comprising sheep chromosomes
