Hypothesis
The study aims to analyze the expression of the anionic glutathione S transferase (GSTi) gene in invasive cervical cancers and its potential role in drug resistance.
Conclusion
High levels of GSTi transcripts in invasive cervical cancers may indicate a link to drug resistance mechanisms.
Supporting Evidence
- GSTi mRNA levels were significantly lower in normal cervix compared to invasive carcinomas.
- 84% of invasive cancers exhibited overexpression of the GSTi gene.
- High GSTi levels were found in squamous cell carcinomas compared to other histological types.
Takeaway
The study found that cervical cancer cells have more of a certain gene that might make them resistant to treatment, while normal cells have less of it.
Methodology
Total RNA from 106 invasive cervical cancers, 3 carcinomas in situ, and 24 normal cervical epitheliums was analyzed using Northern and slot blot hybridization.
Limitations
The study did not find significant differences in GSTi levels between different clinical stages of cervical cancer.
Participant Demographics
The study included untreated patients with invasive cervical cancer and patients treated for other conditions.
