Summary
RNA-cleaving deoxyribozymes (RCDZ) show promise for cancer gene therapy. DNA nanomachines offer a novel approach to enhance RCDZ delivery and targeting for improved cancer treatment efficacy.
Area of Science:
- Biochemistry
- Nanotechnology
- Molecular Biology
Background:
- RNA-cleaving deoxyribozymes (RCDZ) have been investigated for anticancer gene therapy.
- Despite low toxicity, clinical applications are limited by poor accessibility, low intracellular catalytic efficiency, and delivery challenges.
Purpose of the Study:
- To explore the potential of DNA nanotechnology for developing multifunctional RCDZ-based nanomachines.
- To address limitations of RCDZ agents by integrating RNA unwinding, cancer marker recognition, and targeted RNA cleavage functions.
Main Methods:
- Designing DNA nanomachines incorporating RCDZ functionalities.
- Integrating RNA unwinding and cancer marker recognition modules.
- Proposing targeted cleavage of housekeeping gene mRNA in cancer cells.
Main Results:
- Conceptualization of multifunctional DNA nanomachines for cancer therapy.

DNA unwinding helicase enzymes are a type of motor protein. Motor proteins can translocate along filaments or polymers using energy generated from ATP hydrolysis. Helicases are involved in all the important cellular processes where DNA unwinding is required, such as DNA replication, repair, recombination, and transcription. They are present in all living organisms, but vary in their structure, function, and mechanism of action. For example, in prokaryotes, DnaB helicase binds and translocates...

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

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.

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...
