Summary
Activatable Proteolysis-targeting chimeras (PROTACs) offer targeted protein degradation, minimizing side effects. These smart PROTACs activate on demand, enhancing precision cancer therapy by reducing off-site accumulation.
Area of Science:
- Biochemistry
- Molecular Biology
- Pharmacology
Background:
- Proteolysis-targeting chimeras (PROTACs) are emerging therapeutics for protein degradation.
- Systemic administration of PROTACs can lead to off-tissue side effects due to nonspecific accumulation.
- Developing targeted PROTAC activation is crucial for improving therapeutic safety and efficacy.
Purpose of the Study:
- To review the recent advancements in activatable PROTACs.
- To categorize activatable PROTACs based on their stimuli-responsive activation mechanisms.
- To discuss the design principles, therapeutic prospects, and challenges of smart PROTACs.
Main Methods:
- Literature review of recent research on activatable PROTACs.
- Categorization of PROTACs based on activation stimuli (reduction, hypoxia, enzymes, light).
- Analysis of design strategies for stimuli-responsive PROTACs.
Main Results:
- Activatable PROTACs demonstrate on-demand protein degradation.
- Stimuli-responsive elements enable localized activation, reducing off-site effects.
- Various activation mechanisms include reduction, hypoxia, enzymatic cleavage, and light-induced changes.
Conclusions:
- Smart activatable PROTACs represent a promising strategy for precision cancer therapy.
- Targeted activation minimizes systemic toxicity and enhances therapeutic outcomes.
- Further research is needed to overcome challenges and fully realize the potential of activatable PROTACs.

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.

02:26Protein Networks
4.1K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

01:13The Proteasome
1.2K
Eukaryotic cells can degrade proteins through several pathways. One of the most important among these is the ubiquitin-proteasome pathway. It helps the cell eliminate the misfolded, damaged, or unwarranted cytoplasmic proteins in a highly specific manner.
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. This involves participation of a series of enzymes including— E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...

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...

02:58Regulated Protein Degradation
7.7K
It is vital to regulate the activity of enzymatic as well as non-enzymatic proteins inside the cell. This can be achieved either through creating a balance between their rate of synthesis and degradation or regulating the intrinsic activity of the protein. Both these regulation mechanisms play an essential role in the normal functioning of cells.
Protein degradation plays two important roles in the cells. It helps to protect cells from misfolded or damaged proteins before they lead to a...

02:53Adaptive Mechanisms in Cancer Cells
6.0K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
