Summary
Prion protein (PrP(C)) is a novel cancer therapy target. Interfering with its interactions, like with HOP/STI1, effectively controlled glioblastoma growth in animal models, showing promise for anti-tumor treatments.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Prion protein (PrP(C)) plays a role in tumor growth, metastasis, and chemotherapy resistance.
- PrP(C) forms multiprotein complexes on cell membranes, influencing signaling pathways and stem cell self-renewal.
- Cancer stem cells, implicated in tumor origin and relapse, involve PrP(C) interactions.
Purpose of the Study:
- To explore PrP(C)-organized multicomplexes as potential anti-tumor therapeutic targets.
- To investigate the interference of PrP(C) protein-protein interactions as a novel cancer treatment strategy.
Main Methods:
- Targeting protein-protein interactions involving PrP(C).
- Interfering with the interaction between PrP(C) and HOP (STI1).
- Evaluating the control of human glioblastoma growth in animal models.
Main Results:
- Successful interference with PrP(C) and HOP/STI1 interaction.
- Demonstrated control of human glioblastoma growth in preclinical animal models.
- PrP(C)-organized multicomplexes show feasibility as anti-tumor targets.
Conclusions:
- PrP(C) is a promising molecular target for cancer therapies.
- Interfering with PrP(C) interactions offers a novel therapeutic strategy.
- PrP(C)-organized multicomplexes warrant further investigation for anti-tumor applications.

Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

5.1K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

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,...

Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...
