2.1.1.45 | additional information | construction of a cell line expressing the Ugi protein inhibitor of UNG family of uracil DNA glycosylases, which reduces cellular uracil DNA glycosylase activity by at least 45-fold. Genomic uracil levels are increased over 4fold following thymidylate synthase inhibition in the Ugi-expressing cells, but do not detectably increase in UNG proficient cells. No difference in toxicity between the UNG proficient and UNG-inhibited cells to folate or nucleotide-based inhibitors of thymidylate synthase. UNG proficient and UNG-inhibited cells arrest in early S-phase and resume replication progression during recovery from raltitrexed treatment almost identically | Homo sapiens |
