Protein Networks02:26

Protein Networks

4.7K
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,...

Genome-wide Association Studies-GWAS

16.5K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Protein-protein Interfaces

15.0K
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...

Purpose of the Study:

  • To develop a method for computing concept relatedness within a hybrid biomedical knowledge network.
  • To enable the discovery of valuable, implicit knowledge for biomedical research and precision medicine.

Main Methods:

  • Constructed a hybrid biomedical knowledge network integrating multiple ontologies and non-structural data.
  • Developed a Multi-Ontology Relatedness Model (MORM) using set-theoretic operations to compute a relatedness network (RN).
  • Implemented semantic constraints to optimize the search space within the relatedness network.

Main Results:

  • Successfully constructed a hybrid biomedical knowledge network.
  • The Multi-Ontology Relatedness Model (MORM) effectively computes concept relatedness across ontologies.
