Network Analysis Service in Biology

Network Analysis Service in Biology 1

Biological systems are often represented as networks of complex sets of binary interactions or relations between different entities. Essentially, every biological entity has interactions with other biological entities, from the molecular to the ecosystem level, providing us with the opportunity to model biology using many different types of networks such as ecological, neurological, metabolic or molecular interaction networks. Systems biology aims to understand biological entities at the systemic level, analyzing them not only as individual components, but also as interacting systems and their emergent properties. Related to this is network biology which allows the representation and analysis of biological systems using tools derived from graph theory.

Features

  • Small world effect

The network's diameter (the maximum number of steps separating any two nodes) is small, regardless of the network size. This usually means that any two nodes are separated by less than six steps, more or less, reflecting the now widely popularised “six degrees of separation” theory used in social sciences.

  • Scale-free networks

The majority of nodes (proteins) in scale-free networks have only a few connections to other nodes, whereas some nodes (hubs) are connected to many other nodes in the network.

  • Transitivity

The transitivity or clustering coefficient of a network is a measure of the tendency of the nodes to cluster together. High transitivity means that the network contains communities or groups of nodes that are densely connected internally.

Overall Solution

  • Different types of information can be represented in the shape of networks in order to model the cell. The meaning of the nodes and edges used in a network representation depends on the type of data used to build the network.
  • Different types of data will also produce different general network characteristics in terms of connectivity, complexity and structure, where edges and nodes potentially convey multiple layers of information.

Different types of biological networks we can provide include:

1. Protein-protein interaction networks

Network Analysis Service in Biology 3

  • Represent the physical relationships between proteins. They are central to practically every process that takes place in the cell.
  • Proteins are represented as nodes that are linked by undirected edges.

Network Analysis Service in Biology 4

2. Metabolic networks

  • Represent the biochemical reactions that allow an organism to grow, reproduce, respond to the environment and maintain its structure.
  • Metabolites and enzymes take the role of nodes and the reactions describing their transformations are represented as directed edges.
  • Edges can represent the direction of the metabolic flow or regulatory effects of a specific reaction.

3. Gene/transcriptional regulatory networks

Genes and transcription factors are represented as nodes, while the relationship between them is depicted by different types of directional edges.

4. Cell signalling networks

  • Signalling pathways represent the ordered sequences of events and model the information flow within the cell.
  • Gene regulation networks can be considered as a sub-type of cell signalling networks, focusing on a specific signalling event which is often the final stage of a signalling cascade.

5. Genetic interaction networks

  • Genetic interaction is the synergistic phenomenon where the phenotype resulting from simultaneous mutations in two or more genes is significantly different from the phenotype that would result from adding the effects of the individual mutations.
  • Represent a functional relationship between different genes, rather than a physical one.
  • Genes are represented as nodes and their relationships as edges. Depending on the type of evidence behind the interaction, directionality can be inferred for the edges.

Network Analysis Service in Biology

    • Q: What are the basic characteristics of the network?
      • A:

        Degree: A degree of a node is a number of edges in a network that connect node with its neighbors.

        Connectivity: A connectivity represents minimum number edges that need to be removed to make a disconnected graph.

        Shortest path: A shortest path is a path in which the two nodes are connected by the smallest number of intermediate nodes.

        Closeness: A closeness centrality of a node is the reciprocal of the average shortest path length.

        Betweenness centrality: A betweenness centrality of a node is the number of times that a node is included in the shortest path between each pair of nodes, normalized by the total number of pairs.

    • Q: What can network analysis service help us do?
      • A:

        Network analysis may help in choosing the right pose in protein-protein docking, which is important for selecting inhibitor binding sites.

        Network analysis facilitates the search for variable conformation sites and the study of the mechanism of intra-protein signaling.

        The development of protein-protein interaction inhibitors is a promising approach to drug design, and networks demonstrate their suitability for this purpose.

    • Q: How to place an order for network analysis?
      • A: You just need to provide us with the raw files of molecular dynamics simulations, and we can perform network analysis services. If you do not have the relevant trajectory files, we also provide a one-stop analysis service including molecular dynamics simulations.
