Hypothesis
The presence of VEGF mRNA might be used as a marker for relevant levels of hypoxia in cervical cancer.
Conclusion
The study found that different cervical cancer cell lines have varying oxygen levels that induce the up-regulation of VEGF mRNA.
Supporting Evidence
- The presence of hypoxia in tumors correlates with poor prognosis and treatment resistance.
- VEGF mRNA levels were up-regulated in response to low oxygen concentrations.
- Different cervical cancer cell lines showed varying Km values for VEGF mRNA up-regulation.
Takeaway
This study looked at how low oxygen levels in cancer cells can change their behavior, specifically how they produce a certain factor that helps them grow and spread.
Methodology
Suspension cultures of three human cervical cancer cell lines were exposed to defined oxygen concentrations for 2 or 4 hours to measure VEGF mRNA levels.
