Overview

Quantitative assays evaluate helicase and polymerase activities as targeted therapies in cancer treatment.

Key Points

  • The study aims to develop quantitative assays to measure the activities of DNA polymerases and helicases involved in DNA damage repair.
  • Established enzymatic assays to evaluate helicase activity and ATP hydrolysis.
  • Assays optimized for specific helicases such as WRN, DHX9, and BLM.
  • Measured the potency and selectivity of candidate inhibitors.
  • Quantitative assays provide insights into helicase and polymerase function.
  • Inhibitors effectively disrupt ATPase activity, enhancing DNA damage in cancer cells.
  • Assays demonstrate potential for improving therapeutic strategies targeting DNA damage repair.
