  "id": "MLC-T-ONC-013099",
  "term": "DNA polymerase theta inhibitor ART6043",
  "field": "Oncology and biomedicine",
  "definition": "An orally bioavailable selective and reversible inhibitor of DNA polymerase (pol) theta, with potential chemosensitizing and antineoplastic activities. Upon oral administration, pol theta inhibitor ART6043 specifically targets, binds to and inhibits the activity of pol theta. This prevents pol theta-mediated repair of double-stranded DNA breaks via the microhomology-mediated end joining (MMEJ) process. This causes apoptosis and inhibits proliferation in cancer cells. ART6043 may have a synergistic effect if administered in combination with agents that cause DNA damage. Pol theta plays a key role in DNA synthesis and repair that is highly expressed in cancer cells while nearly absent in most healthy tissues. It plays a key role in cancer cell survival.",
