Summary
Proteolysis targeting chimeras (PROTACs) offer a novel method for targeted protein degradation, showing promise in treating gastrointestinal cancers. This technology is advancing rapidly, with 15 PROTACs in clinical trials for various targets.
Area of Science:
- Biochemistry
- Molecular Biology
- Oncology
Background:
- Proteolysis targeting chimeras (PROTACs) are heterobifunctional molecules designed for targeted protein degradation (TPD).
- PROTACs leverage the ubiquitin-proteasome system (UPS) to selectively degrade target proteins.
- This technology offers advantages such as broad targeting, cell permeability, tissue specificity, and oral bioavailability.
Purpose of the Study:
- To review the mechanism, research progress, and clinical applications of PROTACs.
- To summarize achievements in developing PROTACs for gastrointestinal cancers.
- To discuss the benefits and challenges of PROTACs in cancer therapy.
Main Methods:
- Literature review of PROTAC technology and its applications.
- Analysis of PROTAC development for gastrointestinal cancer targets.
- Examination of ongoing clinical trials involving PROTACs.
Main Results:
- PROTACs have demonstrated significant potential in targeted protein degradation.
- Numerous PROTACs targeting gastrointestinal cancers have been developed, with validated targets.
- Fifteen PROTACs are currently in clinical trials, indicating rapid advancement.
Conclusions:
- PROTAC technology represents a powerful strategy for targeted protein degradation in cancer treatment.
- The application of PROTACs in gastrointestinal cancers is a rapidly evolving field with promising clinical outcomes.
- Further research and development are crucial to overcome challenges and maximize the therapeutic potential of PROTACs.

02:56Treatment Resistant Cancers
3.4K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

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.

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

245
Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy. SP binds and activates...
