Hypothesis
Higher levels of mdrl mRNA in bladder tumors may indicate poor prognosis and resistance to chemotherapy.
Conclusion
The study found that mdrl mRNA levels are significantly higher in poorly differentiated high-grade bladder tumors compared to lower-grade tumors.
Supporting Evidence
- mdrl mRNA was detected in all tumor samples analyzed.
- mdrl mRNA levels varied over a 63-fold range among individual tumors.
- High-grade tumors showed significantly higher mdrl levels than low-grade tumors.
Takeaway
This study looked at a gene that helps cancer cells resist treatment, finding that higher levels of this gene in bladder tumors might mean the cancer is harder to treat.
Methodology
The study used a quantitative PCR-based assay to measure mdrl mRNA levels in bladder tumor samples.
Limitations
The study did not find a correlation between mdrl levels and tumor recurrence or progression.
Participant Demographics
The study involved patients with untreated transitional cell carcinomas of the bladder.
