Protein Networks02:26

Protein Networks

4.2K
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,...

ER Retrieval Pathway01:45

ER Retrieval Pathway

4.2K
In the secretory pathway, vesicles transport proteins from one cellular compartment to another in forward transport to deliver the protein to its correct location. Occasionally, misfolded proteins and incorrect proteins escape their original compartments, and a retrieval pathway is used to return the escaped proteins to their original compartment.
The ER uses many checkpoints to prevent the entry of incorrectly folded or a resident protein as cargo onto a transport vesicle. These mechanisms...

Area of Science:

  • Biomedical informatics
  • Network science
  • Machine learning

Background:

  • Biomedical heterogeneous networks (BioHNs) offer potential for relationship prediction.
  • Existing methods struggle to capture both local and global information in BioHNs.
  • Self-supervised representation learning on BioHNs is underexplored.

Purpose of the Study:

  • To propose BioERP, a BioHN-based self-supervised representation learning approach for entity relationship prediction.
  • To simultaneously capture local and global association information in BioHNs.
  • To improve the accuracy of biomedical entity relationship predictions.

Main Methods:

  • Developed a self-supervised meta path detection mechanism for Transformer encoder training.
  • Implemented a biomedical entity mask learning strategy for local association reflection.
  • Concatenated representations from different models to generate two-level vectors for relationship prediction.

Main Results:

  • BioERP outperformed 30 state-of-the-art methods across eight datasets.
  • Achieved near-perfect AUC and AUPR scores for drug-target interaction prediction.
  • Demonstrated BioERP's effectiveness in capturing complex relationships within BioHNs.

Conclusions:

  • BioERP is a promising approach for biomedical entity relationship prediction.
  • The method effectively integrates global structure and local associations.
  • BioERP advances self-supervised learning applications in biomedical network analysis.
