Summary
This study introduces a new computational method to identify key control points in cancer networks. The findings suggest potential new therapeutic strategies by targeting essential proteins for personalized cancer medicine.
Area of Science:
- Network science
- Computational biology
- Cancer research
Background:
- Control theory is applied to network science, particularly in bio-medicine and cancer research.
- Structural controllability identifies driver nodes for network control.
- Cancer networks present complex control dynamics.
Purpose of the Study:
- To develop an efficient method for targeted structural controllability of cancer networks.
- To analyze breast, pancreatic, and ovarian cancer using protein-protein interaction networks.
- To identify driver nodes among FDA-approved drug-target nodes for potential cancer therapies.
Main Methods:
- Constructing protein-protein interaction networks for specific cancer types.
- Focusing on survivability-essential proteins within these networks.
- Applying a novel computational approach to determine structural controllability and identify driver nodes.
Main Results:
- Essential proteins in cancer networks are controllable by a small set of driver nodes.
- The method successfully identified drug-target driver nodes.
- Some identified drug-target nodes are not currently used in therapies for the analyzed cancer types, and some are not used in any cancer therapy.
Conclusions:
- Computational modeling of cancer control dynamics can reveal new therapeutic strategies.
- The developed method aids in understanding cancer network control for personalized medicine.
- Targeting identified driver nodes offers potential for novel and efficient cancer treatments.

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,...

14.8K
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...

03:03mTOR Signaling and Cancer Progression
4.9K
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.

02:53Adaptive Mechanisms in Cancer Cells
7.2K
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.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

01:19Interactions Between Signaling Pathways
7.4K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
