Hypothesis
How are double-stranded RNAs processed by the cell and what factors influence their stability?
Conclusion
The study found that 21- and 24-nucleotide double-stranded RNAs are specifically protected in human cytosolic cell extract, contributing to the longevity of RNA interference effects.
Supporting Evidence
- 21- and 24-nucleotide double-stranded RNAs are relatively protected in human cytosolic cell extract.
- An 18-nucleotide double-stranded RNA is less protected in both cell extract and blood serum.
- The study utilized FRET to monitor RNA stability in real-time.
Takeaway
This study shows that certain types of RNA are better protected from being broken down inside human cells, which helps them work longer.
Methodology
The researchers developed a series of doubly-fluorophore labeled RNAs to study their stability in human cell extracts using fluorescence resonance energy transfer (FRET).
