Protein Networks

Protein Networks

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,...

Evolutionary Relationships through Genome Comparisons

Evolutionary Relationships through Genome Comparisons

Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Genome Annotation and Assembly

Genome Annotation and Assembly

The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.

Synthetic Biology

Synthetic Biology

Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

Background:

Interpreting genome-scale experimental results is crucial but challenging in biomedical research.
Biological networks integrate experimental data with existing knowledge to hypothesize gene-phenotype relationships.
Large and dense biological networks hinder efficient exploration and understanding.

Purpose of the Study:

To develop a visual analytics approach for interactive exploration of large biological networks.
To facilitate the understanding of complex gene-phenotype relationships from high-throughput data.
To provide a tool for comparing multiple network subnetworks.

Main Methods:

Interactive filtering of dense networks using degree-of-interest functions.
Attribute-based layouts for visualizing resulting subnetworks.
An interactive super-network with brushing-and-linking for cross-network component highlighting.

Main Results:

A visual analytics approach integrating interactive filtering and attribute-based layouts was developed.
A super-network facilitates comparison of multiple subnetworks representing different analysis facets.
The approach is implemented as a freely available Cytoscape app.

Conclusions:

The approach's utility was demonstrated through case studies on heart failure patients and beta-blocker treatment.
The study discusses the iterative design process, limitations, and generalizability of the visual analytics method.
This tool aids in the interpretation of complex biological data for hypothesis generation.
