Summary
Ribozymes, or RNA enzymes, are emerging as powerful therapeutic agents for genetic diseases and cancer. These catalysts can be delivered exogenously or harnessed endogenously for gene repair and downregulation.
Area of Science:
- Biochemistry
- Molecular Biology
- Gene Therapy
Background:
- Ribozymes (RNA enzymes) show therapeutic potential for diverse diseases, including metabolic disorders, viral infections, and cancer.
- They function by downregulating or repairing pathogenic genes.
Purpose of the Study:
- To explore the therapeutic applications of ribozymes in gene therapy.
- To discuss strategies for both short-term exogenous delivery and long-term endogenous harnessing of ribozymes.
Main Methods:
- Utilizing naturally occurring ribozymes and novel RNA/DNA catalysts developed through in vitro selection.
- Investigating trans-splicing and RNase P mechanisms for endogenous ribozyme activation.
Main Results:
- Ribozymes can be engineered for targeted gene manipulation.
- Viral-mediated delivery enables sustained therapeutic catalyst expression.
- In vitro selection yields new catalytic RNA and DNA molecules.
- Endogenous cellular ribozymes offer alternative therapeutic pathways.
Conclusions:
- Ribozyme-based therapies offer versatile approaches to treating genetic and acquired diseases.
- Both exogenous delivery and endogenous harnessing strategies are promising for future gene therapy applications.

00:59Gene Therapy
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be inserted. The...
02:47Ribozymes
The term ribozyme is used for RNA that can act as an enzyme. Ribozymes are mainly found in selected viruses, bacteria, plant organelles, and lower eukaryotes. Ribozymes were first discovered in 1982 when Tom Cech’s laboratory observed Group I introns acting as enzymes. This was shortly followed by the discovery of another ribozyme, Ribonulcease P, by Sid Altman’s laboratory. Both Cech and Altman received the Nobel Prize in chemistry in 1989 for their work on ribozymes.

02:15Experimental RNAi
RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

01:29Microorganisms in Medicine and Therapeutics
Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
