Tool Details
- Tool name: S_N40R2 Cell Line
- Tool type: Cell Lines
- Tool sub-type: Continuous
- Parental cell line: SJSA-1
- Tissue: Bone
- Cancer type: Sarcoma
- Disease: Cancer
- Model: Cancer Model
- Conditional: No
- Description: To determine how resistance to MDM2/p53 binding antagonists might develop, SJSA-1 cells were exposed to growth inhibitory concentrations of MDM2 inhibitors, Nutlin-3, and a clonal resistant cell line generated. The p53 mediated responses of parental and resistant cell lines were compared. In contrast to the parental cell lines, p53 activation by Nutlin-3, MI-63 or ionizing radiation was not observed in the SJSA-1 derived cell lines.

- Production details: Resistant cell lines were established by exposing SJSA-1 cells to Nutlin-3. 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 Nutlin-3 for 30 days to generate stage 2 resistant clones.
