Tool Details

  • Tool name: N_M5R1 Cell Line
  • Tool type: Cell Lines
  • Tool sub-type: Continuous
  • Parental cell line: NGP
  • Tissue: Lung
  • Disease: Cancer
  • Model: Cancer Model
  • Conditional: No
  • Description: To determine how resistance to MDM2/p53 binding antagonists might develop, NGP cells were exposed to growth inhibitory concentrations of a MDM2 inhibitor, MI-63, and a clonal resistant cell line was generated. The p53 mediated responses of the parental and resistant cell line were compared. In contrast to the parental cell lines, p53 activation by Nutlin-3, MI-63 or ionizing radiation was not observed in the NGP derived cell line, N_M5R1.
  • Research area: Cancer; Apoptosis and autophagy; Cell biology; Drug development; Genetics
  • Production details: Resistant cell lines were established by exposing NGP cells to MI-63. Single cell derived colonies were isolated with cloning cylinders and the clonal population expanded in culture medium containing the MDM2/p53 antagonist refreshed weekly for 60 days. Stage 1 resistant clones were then further exposed to increased concentrations of MI-63 for 30 days to generate stage 2 resistant clones.
