Figure 4From: R-Roscovitine (Seliciclib) prevents DNA damage-induced cyclin A1 upregulation and hinders non-homologous end-joining (NHEJ) DNA repairRoscovitine inhibits NHEJ activity synergistically when combined with Doxorubicin treatment in A549 cells. A) Analysis by real time PCR of NHEJ plasmid re-ligation activity of untreated A549 cell lysate with the addition of 20 μM Roscovitine, DMSO or Wortmannin. B) Analysis by real time PCR of NHEJ plasmid re-ligation activity in A549 cells treated for 12 hours with 20 μM Roscovitine. Wortmannin was added to untreated cell lysate as a negative control for NHEJ activity in vitro.Back to article page
