Understanding Protein Network Construction and Topological Analysis

Understanding protein interactions and topological structures is central to unraveling the molecular mechanisms of life. Proteins rarely act in isolation; instead, they form dynamic interaction networks that influence biological processes, disease progression, and therapeutic outcomes. The topological properties of these networks—such as connectivity, clustering, and modular organization—provide critical insights into protein function and pathway regulation.

However, analyzing protein networks requires advanced computational methods, domain expertise, and curated datasets. Creative BioMart addresses these challenges by offering professional services in protein network construction, topology prediction, and statistical analysis, enabling researchers to focus on biological interpretation while relying on accurate, high-quality computational outputs.

Representative Case Studies

Case 1: Identification of COPD blood-based biomarkers through network analysis

Banaganapalli et al., 2022. doi:10.1371/journal.pone.0274629

Chronic obstructive pulmonary disease (COPD) is a progressive respiratory disorder with significant global morbidity and mortality. This study used computational analysis of microarray gene expression datasets from blood and lung tissues to identify shared differentially expressed genes (DEGs). A total of 63 DEGs were found, from which 12 hub gene-network clusters (including SREK1, TMEM67, IRAK2, MECOM, and ASB4 ) were prioritized through protein network construction and functional enrichment analysis. These genes were linked to inflammation, immune activity, and airway remodeling. Several, such as IRAK2 and MECOM, were also implicated in pulmonary diseases and lung cancer, highlighting their biomarker potential.

Case 2: Improved detection of protein complexes using link-based clustering

Hu et al., 2021. doi:10.1109/TNSE.2021.3109880

Protein complexes are essential functional modules that drive cellular organization and processes, making their accurate detection critical for biological research. Traditional clustering algorithms often rely on protein-level criteria, overlooking the fact that proteins operate through interactions. To address this, a novel link-based clustering algorithm was developed, focusing on pairwise interaction similarities derived from network topology and Gene Ontology. By formulating the problem as an optimization task, this method effectively identifies overlapping protein complexes. Tests on five yeast and human PPI datasets demonstrated significantly higher detection accuracy compared to state-of-the-art approaches, revealing functionally meaningful complexes with improved precision.
