• To investigate methods for down-regulating or repairing unwanted gene expression.
• To identify new therapeutic strategies for untreated diseases.

Main Methods:

• Utilizing hammerhead ribozymes for gene expression down-regulation.
• Employing group I intron ribozymes for inherited mutation repair.
• Investigating peptide nucleic acids (PNAs) to block gene or RNA function.

Main Results:

• Hammerhead ribozymes effectively down-regulate gene expression in viral infections and cancer.
• Group I intron ribozymes show promise for repairing inherited mutations.
• PNAs are being explored for gene and RNA function inhibition.

Conclusions:
