  Small molecule inhibitors of PCNA/PIP-box interaction suppress translesion DNA synthesis

  摘要：

  Proliferating cell nuclear antigen (PCNA) is an essential component for DNA replication and DNA damage response. Numerous proteins interact with PCNA through their short sequence called the PIP-box to be promoted to their respective functions. PCNA supports translesion DNA synthesis (TLS) by interacting with TLS polymerases through PIP-box interaction. Previously, we found a novel small molecule inhibitor of the PCNA/PIP-box interaction, T2AA, which inhibits DNA replication in cells. In this study, we created T2AA analogues and characterized them extensively for TLS inhibition. Compounds that inhibited biochemical PCNA/PIP-box interaction at an IC50 <5 mu M inhibited cellular DNA replication at 10 mu M as measured by BrdU incorporation. In cells lacking nucleotide-excision repair activity, PCNA inhibitors inhibited reactivation of a reporter plasmid that was globally damaged by cisplatin, suggesting that the inhibitors blocked the TLS that allows replication of the plasmid. PCNA inhibitors increased gamma H2AX induction and cell viability reduction mediated by cisplatin. Taken together, these findings suggest that inhibitors of PCNA/PIP-box interaction could chemosensitize cells to cisplatin by inhibiting TLS. (C) 2013 Elsevier Ltd. All rights reserved.
