CD Genomics provides a comprehensive and integrative approach to analyzing biological networks to better understand complex biological systems.

What is biological network analysis?

Biological network analysis is a computational approach used to study complex biological systems by analyzing the interactions and relationships among various biological components such as genes, proteins, metabolites, and other molecules. It involves the construction of network graphs that represent the nodes (biological components) and edges (interactions or relationships between them) within the system. Different techniques can be used in analyzing biology networks. However, many biological studies compare more than two networks, it requires a comparative analysis of multiple network graphs.

Our Biological Network Analysis Service

Our custom biological network analysis solution involves the construction and analysis of network models. We help our clients in identifying key components and pathways that are involved in various biological processes, such as cell signaling, metabolism, and disease progression, promoting underlying mechanisms of diseases and developing new therapeutic strategies.

Based on our capacities of graph theory, machine learning, and statistical modeling, we build and analyze networks in system biology, including but not limited to:

Protein-Protein Interaction Networks Analysis

Protein-protein interactions (PPIs) is essential for almost every process in a cell. PPINs provide a mathematical representation of PPIs and can be used to assign putative roles to uncharacterized proteins, add detail to signaling pathways, characterize multi-molecular complexes, identify drug targets, and design new proteins. Learn more about our Proteomic Data Analysis Services.

Interactomes Data Analysis

The interactome is a complex and dynamic network of protein-protein interactions (PPIs) that occur within a cell, organism, or specific biological context. However, the interactome remains a valuable resource for understanding the complex network of PPIs that underlie cellular function.

Gene Regulatory Networks (GRNs)

GRNs represent the interactions between genes that regulate their expression. Graph theory can be used to analyze the topology of GRNs, while machine learning can be used to identify key regulatory genes or modules within the network. Statistical modeling can be used to identify significant regulatory interactions between genes and to predict the effect of perturbations on gene expression.

Sequence Similarity Networks (SSNs)

SSNs represent the evolutionary relationships between protein sequences. Graph theory can be used to identify clusters or subgroups of related sequences within the network, while machine learning can be used to predict the function or properties of uncharacterized sequences based on their sequence similarity to known sequences.

Signal Transduction Networks

Signal transduction networks represent the signaling pathways that transmit signals between cells or within a cell. Graph theory can be used to analyze the topology of these networks, while machine learning can be used to predict the effect of perturbations on the signaling pathway or to identify key regulatory nodes within the network.

Metabolic Networks

The metabolic network usually focuses on the mass flow in basic chemical pathways that generate essential components such as amino acids, sugars, and lipids, and the energy required by the biochemical reactions. As such, these networks typically present both protein and metabolite information.

lncRNA–Protein Interaction Networks

lncRNA–protein interaction networks represent the interactions between long non-coding RNAs (lncRNAs) and proteins in a cell. Graph theory can be used to analyze the topology of these networks, while machine learning can be used to identify key regulatory lncRNAs or modules within the network.

Disease Networks

Disease networks are a way of visualizing the connections between diseases and their causative genes. These networks are typically constructed using data from repositories such as the Online Mendelian Inheritance in Man (OMIM), which contains information about genetic disorders and their associated genes.
