Hypothesis
Co-cultivation of murine BMDCs with 67NR mouse mammary carcinoma cells will lead to the development of drug-resistant cancer cells.
Conclusion
The study found that co-cultivation of murine BMDCs and 67NR-Hyg mammary carcinoma cells resulted in the emergence of highly drug-resistant cells.
Supporting Evidence
- The study demonstrated a marked up-regulation of ABC multidrug transporters in the drug-resistant clones.
- Inhibition of transporter function by verapamil reduced drug resistance in the clones.
- The clones exhibited unique gene expression profiles compared to parental cells.
Takeaway
When immune cells and cancer cells grow together, the cancer cells can become super strong and resist medicine that usually kills them.
Methodology
The study involved co-cultivating murine BMDCs with 67NR-Hyg mammary carcinoma cells and analyzing the resulting cell clones for drug resistance and genetic changes.
Limitations
The exact mechanism of how the drug-resistant cells originated (cell fusion vs. horizontal gene transfer) remains unclear.
Participant Demographics
Murine models were used, specifically Tg(GFPU)5Nagy/J mice for BMDCs and Balb/cfC3H mice for 67NR cells.
