Background:

Pathogenicity of dominant genetic disorders, viral infections, and cancers often involves detrimental proteins.
Inhibiting the synthesis of these abnormal proteins is a key therapeutic goal.
Gene expression interference at the messenger RNA (mRNA) level offers a targeted approach.

Purpose of the Study:

To explore the potential of ribozymes for therapeutic applications.
To highlight the advantages of ribozymes over antisense oligodeoxynucleotides.
To discuss the applicability of ribozyme technology to dominant genetic disorders.

Main Methods:

Utilizing ribozymes, which are RNA molecules with catalytic activity.
Designing ribozymes to specifically bind and cleave target mRNA molecules.

Investigating the mechanism of ribozyme-mediated mRNA suppression.

Main Results:

Ribozymes can specifically target and degrade disease-associated mRNA.
Ribozymes offer advantages over antisense oligodeoxynucleotides, including independence from host cell machinery and catalytic turnover.
Successful application of ribozymes demonstrated in viral and neoplastic diseases.

Conclusions:

Ribozyme technology presents a potent strategy for inhibiting abnormal protein synthesis.
This approach holds significant promise for treating dominant genetic disorders, including connective tissue diseases like osteogenesis imperfecta, Marfan syndrome, and craniosynostotic syndromes.
Further research into ribozyme applications for genetic disorders is warranted.
