Protein Networks02:26

Protein Networks

4.3K
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,...

Propagation of Action Potentials01:23

Propagation of Action Potentials

7.9K
The propagation of an action potential refers to the process by which a nerve impulse, or "action potential," travels along a neuron.
Neurons (nerve cells) have a resting membrane potential, with a slightly negative charge inside compared to outside. This is maintained by ion channels, such as sodium (Na+) and potassium (K+) channels, which control the flow of ions. When a stimulus, like a touch or a signal from another neuron, triggers the neuron, sodium channels open, allowing sodium ions to...

Signal Flow Graphs01:18

Signal Flow Graphs

422
Signal-flow graphs offer a streamlined and intuitive approach to representing control systems, providing an alternative to traditional block diagrams. These graphs use branches to symbolize systems and nodes to represent signals, effectively illustrating the relationships and interactions within the system.
In a signal-flow graph, branches denote the system's transfer functions, while nodes represent the signals. The direction of signal flow is indicated by arrows, with the corresponding...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

6.8K
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...

Background:

  • Practical systems are often modeled as complex networks generating rich data.
  • Network reconstruction is crucial but challenged by limited measurable data.
  • Analyzing unknown network structures from partial data is a significant problem.

Purpose of the Study:

  • To develop a method for network reconstruction with extreme data limitations.
  • To explore the relationship between two nodes in a large, hidden network.
  • To determine connection structure, distance, and interaction intensity between two nodes.

Main Methods:

  • A driving-response approach is proposed for network reconstruction.
  • A high-frequency signal is applied to a source node (A).
  • Data from a target node (B) is measured and analyzed to infer network properties.

Main Results:

  • The driving-response method successfully determines the connection structure between two nodes.
  • Effective interaction intensity and distance from node A to node B can be calculated.
