Protein Networks02:26

Protein Networks

4.6K
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,...

Intracellular Signaling Affects Focal Adhesions01:17

Intracellular Signaling Affects Focal Adhesions

3.7K
Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

Metastasis02:30

Metastasis

6.7K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Overview of Cell Signaling01:23

Overview of Cell Signaling

25.6K
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate with the environment.
Cells respond to many types of information, often through receptor proteins positioned on the membrane. For example, skin cells respond to and transmit touch...

Intracellular Signaling Cascades01:24

Intracellular Signaling Cascades

54.3K
Once a ligand binds to a receptor, the signal is transmitted through the membrane and into the cytoplasm. The continuation of a signal in this manner is called signal transduction. Signal transduction only occurs with cell-surface receptors, which cannot interact with most components of the cell, such as DNA. Only internal receptors can interact directly with DNA in the nucleus to initiate protein synthesis. When a ligand binds to its receptor, conformational changes occur that affect the...

Overview of Cell-Matrix Interactions01:24

Overview of Cell-Matrix Interactions

9.6K
The extracellular matrix or ECM holds cells together to form a tissue and allows the cells within the tissue to communicate. ECM comprises proteins such as fibronectin, collagen, laminin, etc. The most abundant protein in this space is collagen. Collagen fibers are interwoven with carbohydrate-containing protein molecules called proteoglycans. ECM allows cell migration and provides a structural scaffold at cell adhesion that anchors the cell when the extracellular matrix proteins interact with...

  • Network Science
  • Computational Social Science

Background:

  • Spreading processes, like epidemic contagion and information propagation, are crucial dynamics in complex networks.
  • Identifying influential nodes is key for controlling or optimizing these spreading phenomena.
  • Existing methods often focus on maximizing overall spread, not targeted dissemination.

Purpose of the Study:

  • To address the need for identifying nodes that can spread information to specific target groups within complex networks.
  • To develop a method for evaluating node influence concerning localized spreading objectives.

Main Methods:

  • Proposing a novel 'reversed local path algorithm' specifically designed for localized spreading.
  • Utilizing simulation-based evaluations to compare the proposed method against existing approaches.

Main Results:

  • The reversed local path algorithm demonstrates superior performance in identifying influential nodes for localized targets.
  • Nodes identified by this method are effective in spreading to targets while avoiding non-target nodes.

Conclusions:

  • The reversed local path algorithm offers a more precise approach for influence maximization in targeted spreading scenarios.
  • This method has practical implications for applications like advertising and news propagation where specific audience reach is desired.
