Hypothesis
The thermodynamic properties of the motifs significantly associated with effective antisense suppression will be similar to those previously discovered as effective.
Conclusion
The study found numerous motifs that are significantly associated with antisense activity, confirming the link between thermodynamic properties and antisense efficiency.
Supporting Evidence
- 155 motifs were found to associate significantly with high antisense suppression activity.
- 202 motifs were found to associate significantly with low antisense suppression activity.
- The average Gibbs free energy of effective sequences was significantly more negative than that of ineffective sequences.
Takeaway
The researchers looked for patterns in DNA sequences that help block gene activity, finding many new patterns that work well.
Methodology
A Monte Carlo randomization procedure was used to assess the association of various motifs with antisense activity.
Potential Biases
Potential bias due to the correlation between local target secondary structure and suppression efficacy.
Limitations
The significance results apply only to the specific dataset used, which may not represent all antisense sequences.
